I'm trying to create a drag and drop destination, and I have the following code
(excerpt):
gboolean
drag_motion (GtkWidget *widget,
GdkDragContext *context,
gint x,
gint y,
guint time,
gpointer data)
{
g_print ("drag motion\n");
gtk_drag_get_data (widget, context,
GDK_POINTER_TO_ATOM(context->targets[0].data), time);
return TRUE;
}
gboolean
drag_drop (GtkWidget *widget,
GdkDragContext *drag_context,
gint x,
gint y,
guint time,
gpointer user_data)
{
g_print ("drag drop\n");
return TRUE;
}
static void
drag_data_received (GtkWidget *widget,
GdkDragContext *context,
gint x,
gint y,
GtkSelectionData *selection_data,
guint info,
guint time,
gpointer data)
{
g_print ("drag data received\n");
gtk_drag_finish (context, TRUE, FALSE, time);
}
static void
shelf_init (GtkWidget *widget)
{
gtk_drag_dest_set (widget, GTK_DEST_DEFAULT_ALL, targets, 1, GDK_ACTION_LINK);
g_signal_connect (G_OBJECT(widget), "drag-motion",
G_CALLBACK(drag_motion), NULL);
g_signal_connect (G_OBJECT(widget), "drag-drop",
G_CALLBACK(drag_drop), NULL);
g_signal_connect (G_OBJECT(widget), "drag-data-received",
G_CALLBACK(drag_data_received), NULL);
g_print ("shelf_init\n");
}
The problem is, after running this code, the mouse is grabbed and not released,
and I end up having to restart my system. Can anyone tell me what I'm doing
wrong?
Also, the drag source is a GtkIconView. What type of selection data will I
receive, and how do I parse it?
