hi
(repost)
I am trying to use a button in the menu of my window(addwidget) to add
another dock to my dock area. ( see file attached)
The widget gets added and it seems to function but i get the following
error:
AttributeError: 'NoneType' object has no attribute 'type'
Traceback (most recent call last):
..pyqtgraph\dockarea\Dock.py", line 170, in resizeEvent
self.setOrientation()
..\pyqtgraph\dockarea\Dock.py", line 143, in setOrientation
if self.container().type() == 'tab':
AttributeError: 'NoneType' object has no attribute 'type'
The error does not happen if the main window is empty ( for the 1st widget
you add), but the following ones do the same
can anybody help?
There is a second button I added(add widget hack), in which I use a
workaround, by creating a temporary area to which I add a widget, and then
move it back to the original one.
Am I missing something ? Am trying to find the proper way of doing it!
