#[repr(transparent)]pub struct DragIcon { /* private fields */ }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§
source§impl DragIcon
impl DragIcon
sourcepub fn create_widget_for_value(value: &Value) -> Option<Widget>
pub fn create_widget_for_value(value: &Value) -> Option<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.
