As mentioned, you have to set object names for everything. And also avoid
adding a layout to a layout. You should put widgets between layouts :

Widget - layout - widget - layout

Yes, after following many recomendations like yours, i found out that the sign " | " actually represent a layout without name in the route, so if you have something like G.Ex: my_window||||my_layout|etc|etc .. that means that you have 3 layouts without name, you have, why i said 3 and not 4 if there are 4 | between my_window and my_layout ? because we have to be aware that one of those " | " is the way how maya represents the hiererchy in paths, in my test, at least in mine, dont mind if we have nested layouts, or widgets in bettween, you just have to name all layouts that will represent the path to the viweport, not the widgets, in first i put a name on the widgets too, but just for testing after i deleted the object name from the widgets and leave it on the layouts and still work on ! thank you ! now everything will be ok !!

Hello, Thanks for the examples but I noticed that none of the icons in
modelEditorIconBar seem to work. Clicking on shaded or wireframe icons have
no effect in the viewport. Does anyone know how to fix this problem? I am
referring to example1.

Thanks

you saw the last few lines i commented out the setObjectName xxxx and
yyyyy, without them, when you run the code in maya, it successfully opens
the ui, but when you press 4 or 5 on the modelPanel, you will see the
updateModelPanelBar
MayaWindow|||formLayout1|viewPanes|modelPanel4|modelPanel5|modelPanel5;
notice the ||| part.
it seems as if without object names set, maya doesn't know how to find the
newly created modelPanel. also if i'm using mainwindow i also see this
error unless i set object names using an awkward workaround.

I've updated the original blog post with a Maya >= 2017 port of that
example code:
http://justinfx.com/2011/11/20/mixing-pyqt4-widgets-and-maya-ui-objects/

I tested it in Maya 2018 and it seems like the toolbar icons in the model
editor worked just fine. Can you confirm?

Thank Justin. I don't have access to my code right now to check the differences between mine and this one but this code works perfectly fine. Thanks again.

Hey Justin,


It seems like putting the paneLayout into a QSplitter causes the issue. I edited your code to add the splitter.

Hey Justin,


It seems like putting the paneLayout into a QSplitter causes the issue. I edited your code to add the splitter.

I've updated the original blog post with a Maya >= 2017 port of that example code:
http://justinfx.com/2011/11/20/mixing-pyqt4-widgets-and-maya-ui-objects/

I tested it in Maya 2018 and it seems like the toolbar icons in the model editor worked just fine. Can you confirm?

you saw the last few lines i commented out the setObjectName xxxx and yyyyy, without them, when you run the code in maya, it successfully opens the ui, but when you press 4 or 5 on the modelPanel, you will see the following error message similar to :

updateModelPanelBar MayaWindow|||formLayout1|viewPanes|modelPanel4|modelPanel5|modelPanel5;

notice the ||| part.

it seems as if without object names set, maya doesn't know how to find the newly created modelPanel. also if i'm using mainwindow i also see this error unless i set object names using an awkward workaround.

I don't really have an answer for you on this one. I tried to shuffle
things around in your latest code example, and tried even creating an
intermediate widget+layout between the splitter and the paneLayout, but the
behaviour did not change. Don't forget, this is all a hack on the Maya UI
so its not unreasonable for things to work incorrectly :-)

** Incoming mail from outside The Mill **

I don't really have an answer for you on this one. I tried to shuffle things around in your latest code example, and tried even creating an intermediate widget+layout between the splitter and the paneLayout, but the behaviour did not change. Don't forget, this is all a hack on the Maya UI so its not unreasonable for things to work incorrectly :-)

Hello, Thanks for the examples but I noticed that none of the icons in
modelEditorIconBar seem to work. Clicking on shaded or wireframe icons have
no effect in the viewport. Does anyone know how to fix this problem? I am
referring to example1.

Thanks
