script editor looses cursor after going to different software and coming back to Maya.

[ynedelin]

Behavior I am used to is this:
if I am typing something in Maya Script Editor Command Input (bottom) section and then ALT+TAB into another software like Notepad and then ALT+TAB back into Maya my cursor is back in script editor at the place I left it so I can continue to type stuff.

This how it used to be on window machines in classic theme until windows 8 and that how it works on osx.

I got a new machine with windows 8 and now when I ALT-TAB back to Maya script editor cursor is not back in the script editor's Command Input (bottom) but some other panel is in focus in Maya so now I have to grab the mouse and click in the Command Input aria manually !
This is very annoying.

Anyone has any suggestions ?
is there a way to force cursor into the Command Input section of the Script editor with code?

Thank you

Yury

I don't know much about this particular problem, since on my OSX machine w/ Maya 2015 it does not lose focus. But you could probably install an event filter on the QApplication, to detect the ApplicationDeactivate and ApplicationActivate events. You could then handle checking if the script editor is up and on top, and if so, give it editing focus again.

Justin,
Thanks for replying, I will try this approach to put script editor in focus.

There is an added issue of putting  the command input section of the script editor in focus.

Hey Yury,

If I understand correctly, this is a preference and if I remember it isn't on by default.

Preferences -> Interface -> Command Line: Hold Focus [x]

Does checking this box solve your problem?

That only seems relevant to the command-line text input box, and not the script editor.

I get this too, on Windows, and also find it quite bothersome. If a fix comes up, my mind would produce more endorphins.

Well for now I have a ghetto workflow to avoid the mouse.

I have assigned this mel command to the ALT+1 hot key

selectCurrentExecuterControl

its in scriptEditorPanel.mel

so now I do ALT+TAB ALT+1

It seems none of Maya windows is selected when user ALT+TAB back to Maya so just selecting menu panel of the script editor fixes this. I will try Justin's solution later this week, it might all we need.

[Marcus Ottosson]

Intrigued by the possibility eliminating this minor annoyance, I followed Justin’s suggestion and wrote a solution.

Run this, or put it in your userSetup.py, and it will restore focus to the Script Editor, if it is available.

from PySide import QtCore, QtGui

class RestoreScriptEditorFocus(QtCore.QObject):
    def eventFilter(self, obj, event):
        if event.type() != QtCore.QEvent.ApplicationActivate:
            return super(RestoreScriptEditorFocus, self).eventFilter(obj, event)

        script_editor = next(w for w in QtGui.qApp.topLevelWidgets() if w.objectName() == "scriptEditorPanel1Window")
        script_editor.activateWindow()
        return True

f = RestoreScriptEditorFocus()
QtGui.qApp.installEventFilter(f)

It’ll also “restore” focus to it, even if it wasn’t the last thing to have focus at the time of leaving the Maya window. Whether that’s a problem or not is too soon to tell, but I’ll leave the implementation for that to the reader.

Enjoy!

@Marcus Ottosson: Awesome!!!

I was trying to hack a version that remembers if last window was actually the scriptEditor. Using QtCore.QEvent.ApplicationDeactivate you easily get when you leave Maya. But getting the last window seems tricky!

QtGui.qApp.activeWindow() does not get you anything at that point.
QtGui.qApp.topLevelWidgets() is not sorted to have topmost window last or something.
cmds.getPanel(withFocus=True) is only sometimes giving you the 'scriptEditorPanel1' :( [wtf?] and
cmds.getPanel(underPointer=True) is kind of unreliable :/

my playground so far: http://pastebin.com/ibq7ZBVD

I'll try If I'm more happy with brute force scriptEditorPanel activation like that already :]
thanks a bunch!!!

Hi Eric, glad you liked it.

Thanks for posting your progress! With that in mind, I gave it another go and came up with this.

from PySide import QtCore, QtGui

class RestoreScriptEditorFocus(QtCore.QObject):

    def __init__(self):
        super(RestoreScriptEditorFocus, self).__init__()
        QtGui.qApp.focusChanged.connect(self.on_focuschanged)
        self.restore = False

    def on_focuschanged(self, old, new):
        self.restore = "cmdScrollFieldExecuter" in old.objectName() if old else False

    def eventFilter(self, obj, event):
        if event.type() == QtCore.QEvent.ApplicationActivate and self.restore:
            script_editor = next(w for w in QtGui.qApp.topLevelWidgets() if w.objectName() == "scriptEditorPanel1Window")
            script_editor.activateWindow()
            return True
        else:
            return super(RestoreScriptEditorFocus, self).eventFilter(obj, event)

f = RestoreScriptEditorFocus()
QtGui.qApp.installEventFilter(f)

In a nutshell, it listens for any change of focus, and records whether or not the change was from the input field of the script editor, apparently called something like “cmdScrollFieldExecuter”. Not sure how consistent this is across versions of Maya.

Fixed issues with a docker Script Editor and also went ahead and made a permanent Gist for it to track revision and facilitate searches via Google.

for me, I keep the script editor in a panel of my layout (saved dev layout).  I found when it's in the panel layout, I can ALT+TAB between apps and still have my cursor at the script editor where I left it.  If it's a floating window, not the case.

[Marcus Ottosson]

So you don’t do anything when docked then?

I hadn’t experienced the issue when it was docked, so figured it’d be safe to simply do nothing.

Hey everybody, first post on this list for me - nice to e-meet you all! :)

Marcus, thanks again for having provided this workaround for preserving Script Editor focus. However I just noticed that this does not seem to work anymore in Maya 2017 (on Windows, that is...) 

I just had a quick look and the following change/addition seems to work for me both in 2017 and in older versions (the change is in line 15):  

            # (...)
            try:
                script_editor = next(w for w in QtGui.qApp.topLevelWidgets() if w.objectName() == "scriptEditorPanel1Window" or w.accessibleName() == "Script Editor")
                script_editor.activateWindow()
                return True

Marcus, I also commented on your Gist on GitHub, but I somehow failed at issuing a pull request for my change to you. Is that even possible for Gists? 

Anyway, here's my forked and updated Gist - hope this is helpful to somebody besides me.  

Cheers, Martin

Hi Marcus, that was fast!  :)  

However I'm afraid I have messed up my updated Gist... :(  

I just updated my Gist again and verified that this works both in 2017 and 2016 on Windows.

Main Changes:

- import block tries to load PySide2 and falls back to PySide

- qApp now belongs to QWidgets (in PySide2) instead of QtGui (in PySide)

Could you please have another look?  Thanks again and sorry about that...

 Link to my forked and updated Gist

Cheers, Martin

No problem, Martin.

I've made another update; removed a few imports and made it PEP08 compliant in terms of line width as well.
