How to embed modelPanel to a pyqt ui (again) ?

[oglop]

i know this has been asked on 2011 and Justine has an awesome example here
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.

example1

from PyQt4 import QtCore,QtGui

import maya.cmds as cmds
import maya.OpenMayaUI as OpenMayaUI

def getMayaWindow():

Wasn't sure if this was a question or another example of how to do it?

Also another thing I found was that Maya didn't seem to like layouts being added to layouts. I had to add a widget in between. Maybe that has changed. Haven't tested it in the latest Maya.

that was a question , because if i do a complex ui, there are many nested layout, and there will be ||| errors, when i press 4 or 5 ? shall i manually call setObjectName on all the "missing" layouts?  this doesn't feel correct to me .)

        ptr <span style="co

...

[Justin Israel]

I'm not sure if there really is a "correct" way to be doing this anyways, since it is the process of hijacking Maya's UI elements and interacting with how it has implemented it's translation between QWidgets and the Maya object path.

I would have to say that as far as I know, and have tested, setting object names on all of the parent elements of the intended Maya UI element is kind of necessary.

The whole thing is pretty much an unsupported trick.

shall i manually call setObjectName on all the “missing” layouts? this doesn’t feel correct to me .)

I might add that an object can only ever have 1 name. So if it turns out Maya is actually using the objectName that you are changing, you might end up breaking things; and there is no undo for that. :)

On the other hand, setting objectNames “manually” certainly isn’t “hacky” or even “manual”; Qt isn’t setting those names for you, they are meant to be set by you for you to distinguish them from other objects, however like I said, Maya may have already done that for a reason.

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

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.

Running the code below adds the splitter. Do you know if there's a work around for this?

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 :-)
