This is exposed for applets that need to do their own drag and drop handling but still want to chain the this function so it can handle icons that are dropped. Use this by setting the drag_and_drop property of AwnThemedIcon and chaining to this function from the applet drag data received handler.

widget :

 An AwnThemedIcon object.

context :

 The GDK drag context.

x :

 The X position of the drop.

y :

 The Y position of the drop.

selection_data :

 The received data.

info :

 The info that has been registered with the target in the GtkTargetList.

evt_time :

 The drag event time.

Property Details

The "applet-name" property

  "applet-name"              gchar*                : Read / Write / Construct

The applet name.

Default value: NULL

The "drag-and-drop" property

  "drag-and-drop"            gboolean              : Read / Write / Construct

Whether to enable the dragging and dropping of icons, so that a user can customize the icon via a user interface. One example of an applet that would not want this behavior enabled is a trash applet that allowed a user to drag and drop files onto it, in order to send them to the trash.

If this value is FALSE, the icon customization behavior can be used as a fallback by calling awn_themed_icon_drag_data_received in a custom signal handler for "drag-data-received".

Default value: TRUE

The "rotate" property

  "rotate"                   GdkPixbufRotation     : Read / Write / Construct

Rotates the icon as per GdkPixbufRotation.

Default value: GDK_PIXBUF_ROTATE_NONE
