Expand description

DragIcon is a Root implementation for drag icons.

A drag icon moves with the pointer during a Drag-and-Drop operation and is destroyed when the drag ends.

To set up a drag icon and associate it with an ongoing drag operation, use for_drag() to get the icon for a drag. You can then use it like any other widget and use set_child() to set whatever widget should be used for the drag icon.

Keep in mind that drag icons do not allow user input.

Implementations§

Gets the widget currently used as drag icon.

Returns

The drag icon

Sets the widget to display as the drag icon.

child

a Widget

Creates a widget that can be used as a drag icon for the given @value.

Supported types include strings, gdk::RGBA and TextBuffer. If GTK does not know how to create a widget for a given value, it will return None.

This method is used to set the default drag icon on drag-and-drop operations started by DragSource, so you don’t need to set a drag icon using this function there.

value

a GValue

Returns

A new Widget for displaying @value as a drag icon.

Gets the DragIcon in use with @drag.

If no drag icon exists yet, a new one will be created and shown.

drag

a gdk::Drag

Returns

the DragIcon

Creates a DragIcon that shows @paintable, and associates it with the drag operation.

The hotspot position on the paintable is aligned with the hotspot of the cursor.

drag

a gdk::Drag

paintable

a gdk::Paintable to display

hot_x

X coordinate of the hotspot

hot_y

Y coordinate of the hotspot
