gtk-sharp 0.0.0.0 neutral Gtk# is thread aware, but not thread safe; See the Gtk# Thread Programming for details. GtkWidget introduces style properties - these are basically object properties that are stored in the style object associated to the . Style properties are set in resource files. This mechanism is used for configuring such things as the location of the scrollbar arrows through the theme, giving theme authors more control over the look of applications without the need to write a theme engine in C. Use , or to obtain the value of a style property. Gtk.Object Atk.Implementor GLib.IWrapper GLib.IWrapper System.IDisposable Method System.Void Makes all newly-created as composite children until the corresponding call. A composite child is a child that's an implementation detail of the container it's inside and should not be visible to people using the container. Composite children aren't treated differently by GTK# (but see vs. ), but e.g. GUI builders might want to treat them in a different way. Method System.Void Pushes onto a global stack of colormaps. Colormap that is pushed by . Pushes onto a global stack of colormaps; the topmost colormap on the stack will be used to create all . Remove with . There's little reason to use this method. Method System.Void Removes a colormap pushed with . Removes a colormap pushed with . Method System.Void Cancels the effect of a previous call to . Cancels the effect of a previous call to . Method Atk.Object Gets a reference to an object's implementation. An . Gets a reference to an object's implementation. Method System.Void Shows a . If the is an unmapped toplevel , a that has not yet been shown, enter the main loop and wait for the window to actually be mapped. Be careful, because the main loop is running, anything can happen during this method. Method System.Void Causes to become the default . The default is activated when the user presses Enter in a window. Default must be activatable, that is, should affect them. The must have the flag set; typically you have to set this flag yourself by calling . Method System.Void Moves a from one to another, handling reference count issues to avoid destroying the . A to move the into. Moves a from one to another, handling reference count issues to avoid destroying the . Method System.Boolean Move focus to particular . Direction of focus movement. if focus ended up inside . This method is used by custom implementations; if you're writing an app, you'd use to move the focus to a particular , and to change the focus tab order. So you may want to investigate those methods instead. is called by containers as the user moves around the window using keyboard shortcuts. indicates what kind of motion is taking place (up, down, left, right, tab forward, tab backward). invokes the event on ; override the default handler for this event in order to implement appropriate focus behavior. The "focus" default handler for a should return if moving in direction left the focus on a focusable location inside that , and if moving in direction moved the focus outside the . If returning , normally call to place the focus accordingly; if returning , they don't modify the current focus location. Method System.Void Should be called by implementations of the remove method on , to dissociate a child from the container. This method is only for use in widget implementations. Method System.Void Creates the GDK (windowing system) resources associated with a . For example, ->window will be created when a is realized. Normally realization happens implicitly; if you show a and all its parent containers, then it will be realized and mapped automatically. Realizing a requires all the widget's parent widgets to be realized; calling realizes the widget's parents in addition to itself. If a is not yet inside a toplevel window when you realize it, bad things will happen. This method is primarily used in widget implementations, and isn't very useful otherwise. Many times when you think you might need it, a better approach is to connect to a event that will be called after the is realized automatically, such as . Or simply to the realize event. Method System.Void Invalidates the rectangular area of a . y coordinate of upper-left corner of rectangle to redraw. x coordinate of upper-left corner of rectangle to redraw. Width of region to draw. Height of region to draw. Invalidates the rectangular area of defined by , , and by calling on the 's window and all its child windows. Once the main loop becomes idle (after the current batch of events has been processed, roughly), the window will receive events for the union of all regions that have been invalidated. Normally you would only use this method in widget implementations. You might also use it, or directly, to schedule a redraw of a or some portion thereof. Frequently you can just call or instead of this method. Those methods will invalidate only a single window, instead of the and all its children. The advantage of adding to the invalidated region compared to simply drawing immediately is efficiency; using an invalid region ensures that you only have to redraw one time. Method System.Void Sets the foreground for a in a particular . The state for which to set the background color. The color to assign (does not need to be allocated), or to undo the effect of previous calls to of . All other style values are left untouched. See also . Method Gdk.Pixbuf A convenience method that uses the theme engine and RC file settings for to look up and render it to a . A stock ID. A stock size. Render detail to pass to theme engine. A new , or if the wasn't known. The should be a stock icon ID such as or . should be a size such as . should be a string that identifies the or code doing the rendering, so that theme engines can special-case rendering for that or code. The pixels in the returned are shared with the rest of the application and should not be modified. The should be freed after use with . Method System.Void Gets the values of a multiple style properties of . The name of the first property to get. A va_list of pairs of property names and locations to return the property values, starting with the location for . Gets the values of a multiple style properties of . Used primarily by language bindings. Method System.Void Recursively shows a , and any child (if the widget is a container). Recursively shows a , and any child (if the widget is a container). Method System.Void Sets the text for a in a particular state. The state for which to set the text color. The color to assign (does not need to be allocated), or to undo the effect of previous calls to of . All other style values are left untouched. The text color is the foreground color used along with the base color (see ) for such as and . See also . Method Pango.Context Creates a new with the appropriate colormap, font description, and base direction for drawing text for . The new . See also . Method System.Boolean Utility method; intended to be connected to the event on a . Returns . The method calls on its argument, then returns . If connected to , the result is that clicking the close button for a window (on the window frame, top right corner usually) will hide but not destroy the window. By default, GTK+ destroys windows when is received. Method System.Void Obtains ->. A to be filled in. Obtains ->, unless someone has forced a particular geometry, in which case it returns that geometry instead of the widget's . This method differs from in that it retrieves the last size request value from ->, while the method computes the size request and fill in ->, and only then returns ->. Method System.Void Causes a to have the keyboard focus for the it's inside. The must be a focusable , such as a ; something like won't work (More precisely, it must have the flag set). Method System.Void Equivalent to calling for the entire area of a . Equivalent to calling for the entire area of a . Method System.Void Given an accelerator group, , and an accelerator path, , sets up an accelerator in so whenever the key binding that is defined for is pressed, will be activated. Path used to look up the the accelerator. A . This removes any accelerators (for any accelerator group) installed by previous calls to . Associating accelerators with paths allows them to be modified by the user and the modifications to be saved for future use. This is a low level method that would most likely be used by a menu creation system like . If you use , setting up accelerator paths will be done automatically. Method System.Void Flags a to be displayed. Any that isn't shown will not appear on the screen. If you want to show all the in a container, it's easier to call on the container, instead of individually showing the . Remember that you have to show the containers containing a , in addition to the itself, before it will appear onscreen. And that when a toplevel container is shown, it is immediately realized and mapped; other shown are realized and mapped when their toplevel container is realized and mapped. Method System.Boolean For that support scrolling, sets the scroll adjustments. An adjustment for horizontal scrolling, or . An adjustment for vertical scrolling, or . Returns if the supports scrolling. For that don't support scrolling, does nothing and returns . that don't support scrolling can be scrolled by placing them in a , which does support scrolling. Method Pango.Layout Creates a new with the appropriate colormap, font description, and base direction for drawing text for . text to set on the layout (can be ). The new . If you keep a created in this way around, in order notify the layout of changes to the base direction or font of this , you must call in response to the and events for the . Method System.Void Reset the styles of and all descendents, so when they are looked up again, they get the correct values for the currently loaded RC file settings. This method is not useful for applications. Method System.Boolean For that can be "activated" (buttons, menu items, etc.) this method activates them. Returns if the was activatable. Activation is what happens when you press Enter on a widget during key navigation; clicking a button, selecting a menu item, etc. If the isn't activatable, the method returns . Method System.Void Sets the background color for a in a particular state. The state for which to set the background color. The color to assign (does not need to be allocated), or to undo the effect of previous calls of . All other style values are left untouched. See also . Method System.Boolean Rarely-used method. This method is used to emit the events on a . A . Return from the event emission ( if the event was handled) If you want to synthesize an event though, don't use this method; instead, use to invalidate a region of the window. Method System.Void Reverses the effects of , causing the to be hidden (invisible to the user). Reverses the effects of , causing the to be hidden (invisible to the user). Method System.Void Sets the base color for a in a particular state. The state for which to set the base color. The color to assign (does not need to be allocated), or to undo the effect of previous calls to of . All other style values are left untouched. The base color is the background color used along with the text color (see ) for such as and . See also . Method System.Void Recursively resets the shape on and its descendants. Recursively resets the shape on this and its descendants. Method System.Void Modifies style values on the . The holding the style modifications. Modifications made using this technique take precedence over style values set via an RC file, however, they will be overriden if a is explicitely set on the using . The structure is designed so each field can either be set or unset, so it is possible, using this method, to modify some style values and leave the others unchanged. Note that modifications made with this method are not cumulative with previous calls to or with such methods as . If you wish to retain previous values, you must first call , make your modifications to the returned , then call with that . On the other hand, if you first call , subsequent calls to such methods will have a cumulative effect with the initial modifications. Method System.Void Sets the minimum size of a ; that is, the 's size request will be by . Width should request, or -1 to unset. Weight should request, or -1 to unset. You can use this method to force a to be either larger or smaller than it normally would be. In most cases, is a better choice for toplevel windows than this method; setting the default size will still allow users to shrink the window. Setting the size request will force them to leave the window at least as large as the size request. When dealing with window sizes, can be a useful method as well. Note the inherent danger of setting any fixed size - themes, translations into other languages, different fonts, and user action can all change the appropriate size for a given . So, it's basically impossible to hardcode a size that will always be correct. The size request of a is the smallest size a can accept while still methoding well and drawing itself correctly. However in some strange cases a may be allocated less than its requested size, and in many cases a may be allocated more space than it requested. Method System.Boolean Activates the targets associated with the mnemonic. To be added: an object of type 'bool' if the activation is done. Method System.Void Gets the size request that was explicitly set for the using . Return location for width, or . Return location for height, or . A value of -1 stored in or indicates that that dimension has not been set explicitly and the natural requisition of the will be used intead. See . To get the size a will actually use, call instead of this method. Method System.Boolean Removes an accelerator from , previously installed with . Accel group for this . GDK keyval of the accelerator. Modifier key combination of the accelerator. Returns whether an accelerator was installed and could be removed. Removes an accelerator from , previously installed with . Method System.Void Causes a to be unmapped if it's currently mapped. This method is only for use in widget implementations. Method System.Void Causes a to be mapped if it isn't already. This method is only for use in widget implementations. Method Gdk.Region Computes the intersection of a 's area and , returning the intersection. A , in the same coordinate system as ->allocation. That is, relative to ->window for ; relative to the parent window of ->window for widgets with their own window. A newly allocated region holding the intersection of and . The coordinates of the return value are relative to ->window for , and relative to the parent window of ->window for widgets with their own window. The result may be empty, use to check. Method System.Void Flags a to have its size renegotiated; should be called when a for some reason has a new . This method is only for use in widget implementations. One example, when you change the text in a , it queues a resize to ensure there's enough space for the new text. Method System.Void Sets the font to use for a . The font description to use, or to undo the effect of previous calls to . All other style values are left untouched. See also . Method System.Int32 Very rarely-used method. This method is used to emit an events on a . A . Return from the event emission ( if the event was handled). This method is not normally used directly. The only time it is used is when propagating an to a child , and that is normally done using . If you want to force an area of a window to be redrawn, use or . To cause the redraw to be done immediately, follow that call with a call to . Method System.Void Causes a to be unrealized (frees all GDK resources associated with the widget). This method is only useful in widget implementations. Method System.Void Ensures that has a style (->style). Not a very useful method; most of the time, if you want the style, the is realized, and realized are guaranteed to have a style already. Method System.Boolean Determines whether is somewhere inside , possibly with intermediate containers. Another . Returns if ancestor contains as a child, grandchild, great grandchild, etc. Determines whether is somewhere inside , possibly with intermediate containers. Method System.Void Adds the events in the bitfield to the event mask for . See for details. Method System.Void Recursively hides a and any child . Recursively hides a and any child . Method System.Void Reverts the effect of a previous call to . Reverts the effect of a previous call to . This causes all queued events on to be emitted. Method System.Void Sets a shape for this 's GDK window. This allows for transparent windows etc., see for more information. Shape to be added, or to remove an existing shape. X position of shape mask with respect to the window. Y position of shape mask with respect to the window. Sets a shape for this 's GDK window. This allows for transparent windows etc., see for more information. Method System.Void Emits a event for the child property on . The name of a child property installed on the class of widget's parent. Emits a event for the child property on . Method System.Void Destroys a . Equivalent to , except that you don't have to cast the to . When a is destroyed, it will break any references it holds to other objects. If the is inside a container, the will be removed from the container. If the is a toplevel (derived from ), it will be removed from the list of toplevels, and the reference GTK+ holds to it will be removed. Removing a from its container or the list of toplevels results in the being finalized, unless you've added additional references to the with .In most cases, only toplevel widgets (windows) require explicit destruction, because when you destroy a toplevel its children will be destroyed as well. Method System.Void Stops emission of events on . The events are queued until is called on . Method System.Void This method is only used by subclasses, to assign a size and position to their child . A position and size to be allocated to . This fuction is only used by subclasses, to assign a size and position to their child . Method System.Void Disposes the resources associated with the object. Constructor Internal constructor Pointer to the C object. An instance of Widget, wrapping the C object. This is an internal constructor, and should not be used by user code. Constructor Internal constructor. An instance of . This is an internal constructor, and should not be used by user code. Property Gdk.Visual Obtains the visual of the default colormap. Returns a visual of the default colormap. Not really useful; used to be useful before existed. Property Gtk.Style Obtains the default style used by all initially. Returns the default style. This object is owned by GTK+ and should not be modified or freed. Returns the default style used by all initially. Property Gdk.Colormap Sets or obtains the default colormap to use when creating . A colormap (see ). A . is a better method to use if you only want to affect a few widgets, rather than all widgets. Property Gtk.TextDirection Sets or obtains the default reading direction for . A . A . Where the direction has not been explicitly set by . Property Gdk.Window To be added To be added: an object of type 'Gdk.Window' To be added Property Gdk.Rectangle To be added To be added: an object of type 'Gdk.Rectangle' To be added Property Atk.Object Obtains the default reading direction for . A . Obtains the default reading direction for . Property Gtk.TextDirection Sets or obtains the reading direction on a particular . A . The reading direction for the . This direction controls the primary direction for containing text, and also the direction in which the children of a container are packed. The ability to set the direction is present in order so that correct localization into languages with right-to-left reading directions can be done. Generally, applications will let the default reading direction present, except for containers where the containers are arranged in an order that is explicitely visual rather than logical (such as buttons for text justification). If the direction is set none, then the value set by will be used. Property Gdk.Colormap Sets or obtains the colormap that will be used to render . A colormap (see ). A . Widget must not have been previously realized. Property System.Boolean Sets or obtains whether should be mapped along with its when its parent is mapped and has been shown with . If , should be mapped along with its parent. Returns if the is mapped with the parent. The child visibility can be set for before it is added to a container with , to avoid mapping children unnecessary before immediately unmapping them. However it will be reset to its default state of when the is removed from a container. Note that changing the child visibility of a does not queue a resize on the . Most of the time, the size of a is computed from all visible children, whether or not they are mapped. If this is not the case, the container can queue a resize itself. This property is only useful for container implementations and never should be called by an application. Property System.String Sets or obtains a composite name. The name to set. The composite name of , or if is not a composite child. The string should not be freed when it is no longer needed. The must be a composite child of its parent; see . Property Gtk.Widget Obtains the topmost in the container hierarchy is a part of. The topmost ancestor of , or itself if there's no ancestor. Note the difference in behavior against , would return if wasn't inside a toplevel window, and if the window was inside a GtkWindow-derived which was in turn inside the toplevel . While the second case may seem unlikely, it actually happens when a is embedded inside a within the same application. To reliably find the toplevel , use and check if the flag is set on the result. Property System.Boolean Sets whether a size allocation changes, the entire is queued for drawing. the entire will be redrawn when it is allocated to a new size. only the new portion of the will be redrawn. Returns because it is on by Default, but returns if you turn it off. By default, this setting is and the entire is redrawn on every size change. If your leaves the upper left are unchanged when made bigger, turning this setting on will improve performance. Note that for setting this flag to turns off all allocation on resizing: the will not even redraw if its position changes; this is to allow containers that don't draw anything to avoid excess invalidations. If you set this flag on a that does draw on ->window, you are responsible for invalidating both the old and new allocation of the when the is moved and responsible for invalidating regions newly when the increases size. Property System.Boolean Use this property to turn off the double buffering. is on by Default, if you want to turn off double buffering no use call for true because it is default. Returns because double buffering is on by Default, but returns if you turn it off. Widgets are double buffered by default, you can use this property to turn off the buffering. "Double buffered" simply means that and are called automatically around events sent to the . diverts all drawing to a 's window to an offscreen buffer, and draws the buffer to the screen. The result is that users see the window update in one smooth step, and don't see individual graphics primitives being rendered. In very simple terms, double buffered don't flicker, so you would only use this property to turn off double buffering if you had special needs and really knew what you were doing. Property Gtk.Settings Obtains the settings object holding the settings (global property settings, RC file information, etc) used for this . The relevant object. Note that this property can only be called when the is attached to a toplevel, since the settings object is specific to a particular . Property Gdk.Window Sets or obtains 's parent window. The new parent window. The parent window of . Sets or obtains 's parent window. Property Pango.Context Obtains a with the appropriate colormap, font description and base direction for . Unlike the context returned by , this context is owned by the (it can be used until the screen for the changes or the is removed from its toplevel), and will be updated to match any changes to the 's attributes. If you create and keep a using this context, you must deal with changes to the context by calling on the layout in response to the and events for the . Property Gtk.StateType Sets the state of a (insensitive, prelighted, etc.). New state for . The of the . Usually you should set the state using wrapper fuctions such as . This property is for use in widget implementations. Property Gdk.Visual Obtains the visual that will be used to render . The visual for . Obtains the visual that will be used to render . Property Gtk.RcStyle Obtains the current modifier style for the .(As set by ) The modifier style for the . This rc style is owned by the . If no style has previously set, a new will be created with all values unset, and set as the modifier style for the . If you make changes to this rc style, you must call , passing in the returned rc style, to make sure that your changes take effect. Caution: passing the style back to will normally end up destroying it, because copies the passed-in style and sets the copy as the new modifier style, thus dropping any reference to the old modifier style. Add a reference to the modifier style if you want to keep it alive. Property System.Boolean Whether the is visible. If the widget is set to be visible. if the widget is meant to be visible. Property System.Int32 Override for the width request for the . The width to be set for the . The width of the . Or -1 if natural request should be used. Property System.Boolean Whether the responds to input. If the is set to respond to input. if the responds to input. Property System.Int32 Obtains or sets the event mask for the (a bitfield containing flags from ). Event mask. Event mask for . The event mask determines which events a will receive. Keep in mind that different widgets have different default event masks, and by changing the event mask you may disrupt a 's fuctionalit, so be careful. This property must be called while a is unrealized. Consider for widgets that are already realized, or if you want to preserve the existing event mask. This property can't be used with widgets; to get events on those events, place them inside a and receive events on the event box. These are the events that the will receive. Property System.Boolean Whether to make the receive the default action when it is focused. If the will receive the default action when is focused. if the will receive the default action when is focused. Property System.Boolean Whether the has the input focus.

The for the toplevel for this . This method can only be called after the has been added to a widget hierarchy with a at the top. In general, you should only create display specific resources when a has been realized, and you should free those resources when the is unrealized. Property Gdk.Screen Obtains the from the toplevel window associated with this . The for the toplevel for this . This method can only be called after the has been added to a widget hierarchy with a at the top. In general, you should only create screen specific resources when a has been realized, and you should free those resources when the is unrealized. Property System.Boolean Determines if the is the focus widget within its toplevel. if the is the focus widget. This does not mean that the flag is necessarily set; will only be set if the toplevel additionally has the global input focus.

Method System.Void Obtains the location of the mouse pointer in coordinates. Return location for the X coordinate, or . Return location for the Y coordinate, or . Widget coordinates are a bit odd; for historical reasons, they are defined as ->window coordinates for widgets that are not , and are relative to ->allocation.x, ->allocation.y for widgets that are . Method System.Boolean Translate coordinates relative to 's allocation to coordinates relative to 's allocations. A . X position relative to source . Y position relative to source . Location to store X position relative to . Location to store Y position relative to . Returns if either was not realized, or there was no common ancestor. In this case, nothing is stored in and . Otherwise . In order to perform this operation, both widgets must be realized, and must share a common toplevel. Method System.Void Obtains the full path to . Location to store length of the path, or . Location to store allocated path string, or . Location to store allocated reverse path string, or . The path is simply the name of a and all its parents in the container hierarchy, separated by periods. The name of a comes from . Paths are used to apply styles to a in gtkrc configuration files. Widget names are the type of the by default (e.g. "") or can be set to an application-specific value with . By setting the name of a , you allow users or theme authors to apply styles to that specific in their gtkrc file. fills in the path in reverse order, i.e. starting with 's name instead of starting with the name of 's outermost ancestor.

Event GtkSharp.WidgetEventHandler To be added To be added Method System.Void Obtains the preferred size of a . A . The container uses this information to arrange its child widgets and decide what size allocations to give them with . You can also call this method from an application, with some caveats. Most notably, getting a size request requieres the to be associated with a screen, because font information may be needed. Multihead-aware applications should keep this in mind. Also remember that the size request is not necessarily the size a will actually be allocated. Method System.Void Obtains the value of a style property of . The name of a style property.
