Re: Drag'n'Drop and SelectionData

[Flavio Danesse <fdanesse gmail com>]

Yo lo hago de esta forma:

I do it this way:

        my_widget = gtk. . . .

        my_widget.drag_source_set(gtk.gdk.BUTTON1_MASK, targets, gtk.gdk.ACTION_MOVE)

        . . .

        my_vbox.drag_dest_set(gtk.DEST_DEFAULT_ALL, targets, gtk.gdk.ACTION_MOVE)

        my_vbox.connect("drag-drop", self.drag_drop)

        

        . . .

        

    def drag_drop(self, destino, drag_context, x, y, cosas):

        objeto = drag_context.get_source_widget()

        if objeto.get_parent() == destino: return

    

        objeto.get_parent().remove(objeto)

        destino.pack_start(objeto, False, False, 1)

targets = [("Moviendo", gtk.TARGET_SAME_APP, 1)]

Hey,

In an application I have a gtk.VBox filled with own widgets. The plan is
to let the user reorder these widgets per drag and drop.

These widgets are set as the drag_sources and the parent VBox as the
drag destination. Now I need to somehow inform the VBox which child
widget was moved. If I understood correctly it's SelectionData what is
used for that.
I would like to add a link of the child to SelectionData to be able to
reorder the children as the user wishes (if you see better alternatives
here, please tell me)
However the documentation states: "In PyGTK the selection data is always
a string...". Does that mean that I need to convert my widgets to a
string and then back to a widget for the drag and drop process?
Or do I miss another way or best practice to exchange this information?

Thanks for your help!
Paul
