Problem This is in response to Vadim's comments with regards to "attaching the handle of a toolbar to another place".
I created this example to show that it's not possible to do so using the standard GtkHandleBox. Try dragging the toolbars to a different position. Although you can place it in a different position manually, when you click on the main window, the toolbar will be hidden behind the main window. (You have to drag the main window away to reveal the toolbars hiding behind.)
Solution
- You will find that in PHP-GTK the detachable toolbar remembers where is its "home". It refuse to stay in other's home.
- For example, for toolbar 1, snapping will only occur with its own "home".
- If you try to drag toolbar 1 to the "home" of toolbar 2 or 3, it won't snap to either home.
- This is the reason why you cannot swap two detachable toolbars by dragging to each other's home.
