Methods for controlling drag and drop handling.

Gtk# has a rich set of methods for doing inter-process communication via the drag-and-drop metaphor. Gtk# can do drag-and-drop (DND) via multiple protocols. The currently supported protocols are the Xdnd and Motif protocols. As well as the methods listed here, applications may need to use some facilities provided for . Also, the Drag and Drop API makes use of events in the class. Constructor

A constructor.

Method Gdk.DragContext The source . The targets (data formats) in which the source can provide the data. A bitmask of the allowed drag actions for this drag. The button the user clicked to start the drag. The event that triggered the start of the drag.

Initates a drag on the source side.

The context fot this drag. The method only needs to be used when the application is starting drags itself, and is not needed when is used. Method System.Boolean A . X coordinate of a start of drag. Y coordinate of a start of drag. Current X coordinate. Current Y coordinate.

Checks to see if a mouse drag starting at (, ) and ending at (, ) has passed the GTK# drag threshold, and this should trigger the beginning of a drag-and-drog operation.

if the drag threshold has been passed. Method System.Void a

To be added Method Gdk.Atom Drag destination . Drag context. List of droppable targets, or to use .

Looks for a match between ->targets and the , returning the first matching target, otherwise returning GDK_NONE.

First target that the source offers and the dest can accept. or GDK_NONE. should usually be the return value from but some widgets may have different valid targets for different parts of the ; in that case, they will have to implement a drag_motion handler that passes the correct target list to this method. Method Gtk.TargetList A .

Returns the list of targets this can accept from drag-and-drop.

The , or if none. Method System.Boolean a to test.

Tests if a widget is set to raise drag motion events.

if , the widget raises . Method System.Void a a , which types of default drag behavior to use a , table of targets that can be accepted a , default behaviors

Register a drop site and possibly add default behaviors.

Method System.Void A . The window to which to foward drag events. The drag protocol which the accepts (You can use to determine this). If , send the same coordinates to the destination, because it is an embedded subwindow.

Sets this as a proxy for drops to another window.

Method System.Void A that's a drag destination. List of droppable targets, or for none.

Sets the target types that this can accept from drag and drop.

The must first be made into a drag destination with . Method System.Void the to configure. turns on motion events if .

Sets the generic drag motion behavior for a widget.

This method can be used to make a widget raise events despite its target settings and flags, allowing a widget to perform generic actions regardless of the source widget's target settings. Method System.Void A .

Clears information about a drop destinantion set with .

The will no longer receive notification of drags. Method System.Void The drag context. A flag indicating whether the drop was successful. A flag indicating whether the source should delete the original data (this should be for a move). The timestamp from the event.

Informs the drag sourcre that the drop is finished, and that the data of the drag will no longer be repaired.

Method System.Void The that will receive the event. The drag context. The target (form of the data) to retrieve. A timestamp for retrieving the data. This will generally be the time received in a or event.

Obtains the data associated with a drag.

When the data is received or the retrieval fails, GTK# will emit a event. Failure of the retrieval is indicated by the length field of the signal parameter being negative. However, when is called implicitely because the was set, then the will not receive notification of failed drops. Method Gtk.Widget A (destination side) drag context.

Determines the source for a drag.

If the drag is occurring within a single application, a pointer to the source . Otherwise, . Method System.Void A to highlight.

Draws a highlight around a .

This will attach handlers to and , so the highlight will continue to be displayed until is called. Property System.Obsolete("Replaced by SetIconDefault(ctx)") Gdk.DragContext

Obsolete. Replaced by

Method System.Void The context of the drag (this must be called with a context for the source side of a drag).

Sets the icon for a particular drag to the default icon.

Method System.Void The drag context. name of an Icon in the Icon theme. the x offset within the icon of the hotspot. the y offset within the icon of the hotspot.

Sets the icon for a drag using a name from an Icon theme.

Method System.Void The context for a drag (this must be called with a context for the source side of a drag). The to use as the drag icon. The X offset within of the hotspot. The Y offset within of the hotspot.

Sets as the icon for a given drag.

Method System.Void The context of the drag (this must be called with a context for the source side of a drag). The ID of the stock icon to use for the drag. The X offset within the icon of the hotspot. The Y offset within the icon of the hotspot.

Sets the icon for a given drag from a stock ID.

Changes the icon for a to a given .

GTK# will not destroy the icon, so if you don't want it to persist, you should connect to the event and destroy it yourself. Method System.Void a

Sets the icon that will be used for drags from a particular source to a stock icon.
