gtk-sharp 0.0.0.0 neutral Gtk# is thread aware, but not thread safe; See the Gtk# Thread Programming for details. An object for rendering a single cell on a The is a base class of a set of objects used for rendering a cell to a . These objects are used primarily by the widget, though they are not tied to them in any specific way. It is worth noting that is not a and cannot be treated as such. The primary use of a is for drawing a certain graphical elements on a . Typically, one is used to draw many cells on the screen. To this extent, it is not expected that a keep any permanent state around. Instead, any state is set just prior to use. Then, the cell is measured using . Finally, the cell is rendered in the correct location using . There are a number of rules that must be followed when writing a new . First and foremost, it is important that a certain set of properties will always yield a of the same size, barring a change. The also has a number of generic properties that are expected to be honored by all children. Gtk.Object GLib.IWrapper System.IDisposable Method System.Void Invokes the virtual render function of the . an object of type an object of type an object of type an object of type an object of type an object of type The three passed-in rectangles are areas of . Most renderers will draw within ; includes the blank space around the cell, and also the area containing the tree expander; so the rectangles for all cells tile to cover the entire window. is a clip rectangle. Method System.Void Sets the renderer size to be explicit, independent of the properties set. an object of type an object of type Method System.Void Fills in and with the appropriate size of . an for the width an for the height Method System.Boolean Passes an activate event to the for possible processing. an object of type an object of type an object of type an object of type an object of type an object of type an object of type Some s may use events; for example, toggles when it gets a mouse click. Method System.Void Disposes the resources associated with the object. Constructor Internal constructor Pointer to the C object. An instance of CellRenderer, wrapping the C object. This is an internal constructor, and should not be used by user code. Property System.Int32 The fixed height. an object of type an object of type Property System.Boolean Display the cell. an object of type an object of type Property System.Single The x-align. an object of type an object of type Property System.Int32 The fixed width. an object of type an object of type Property System.Single The y-align. an object of type an object of type Property System.Boolean Row has children. an object of type an object of type Property System.UInt32 The ypad. an object of type an object of type Property System.UInt32 The xpad. an object of type an object of type Property System.Boolean Row is an expander row, and is expanded. an object of type an object of type Property Gtk.CellRendererMode Editable mode of the CellRenderer. an object of type an object of type Property Gdk.Color Cell background color as a . a a Property System.String Cell background color as a . a a Property GLib.GType GType Property. a Returns the native value for . Constructor Protected Constructor. a a Chain to this constructor if you have manually registered a native value for your subclass. Constructor Protected constructor. a Method System.Void Obtains the and needed to render the cell. a a a a a a Used by view widgets to determine the appropriate size for the passed to gtk_cell_renderer_render(). If is not , fills in the x and y offsets (if set) of the cell relative to this location. Please note that the values set in and , as well as those in and are inclusive of the xpad and ypad properties. Method System.Void Invokes the virtual render function of the . The three passed-in rectangles are areas of window. Most renderers will draw within ; the xalign, yalign, xpad, and ypad fields of the should be honored with respect to . includes the blank space around the cell, and also the area containing the tree expander; so the rectangles for all cells tile to cover the entire window. is a clip rectangle. a to render to a , the widget that owns a , entire cell area (including tree expanders and maybe padding on the sides) a , area normally rendered by a cell renderer a , area that needs updating a , flags that affect rendering Method Gtk.CellEditable Passes an activate event to the for possible processing. a a a a a a a Some cell renderers may use events; for example, toggles when it gets a mouse click. Event System.EventHandler This event is fired when the user cancels the process of editing a cell. For example, an editable cell renderer could be written to cancel editing when the user presses Escape. Method System.Void Default handler for the event. Override this method in a subclass to provide a default handler for the event. Method System.Void Causes the cell renderer to fire an event. This function is for use only by implementations of cell renderers that need to notify the client program that an editing process was canceled and the changes were not committed.
