Mac OS X support about bqt

[melMass]

Yep my bad it works well, I ended up using a fork of bqt for the specific use case I had but I also tried again with bqt master with similar results

[melMass]

Nope I used this here which is now very outdated: https://github.com/melMass/bqt

I'll start fresh and rety bqt soon as I'm currently reimplementing a lot of my tools in pyside6.

I don't know if you use/heard of Prism v2, it's a pretty awesome asset/shot manager. Most of its core will be open source (it already is but just not "deployed" anywhere yet). The most impressive feature to me is how each integrations are seamless and really well made (some of these will be payed at the end of this month), it's all pyqt based but they seem to be able to ship a very minimal build, I just asked over their discord to know more:

I believe a tech art community member completed the Mac support, yes. I do not own a Macintosh so I can not test it for you. the blender_applications\darwin_blender_application.py file looks complete to me.

[bob-white]

I believe there is a dependency on the PyObjc project to make it work. Much like we need pywin32 to make the windows version work.

[skarndev]

I can't seem to be able to install AppKit with pip. Where can I grab the dependencies?

[cmcpasserby]

unless someone else has taken it, over i was never able to get mac support fully working

[Amatobahn]

Last I recall we had it partially working but not at the same level of functionality as we have currently on windows

[bob-white]

I can't seem to be able to install AppKit with pip. Where can I grab the dependencies?

pip install pyobjc should get you AppKit

[skarndev]

It seems there is still an issue. In the Darwin Blender application, there is a method with __ (double underscore) being called which does not exist in the class. And the handler does not start the Window correctly as "startup" in file condition is not fulfilled? Any idea on how to fix the last one?

which method is this? afraid I won't be much help here since I don't have a mac.

the missing startup file has now been added, see PR #22

Hi,

Last time I tried bqt it wasn't working on either mac or windows, @hannesdelbeke just notified me on blender chat that the current master should fix my issues, I will give it another go today and I'm able to test/debug it on mac if needed

[hannesdelbeke]

did you get a chance to test on mac?

[hannesdelbeke]

thanks for your quick response 🙏
will close this thread for now then, sounds like it works

[hannesdelbeke]

This might not work as intended due to the focus operator.
curious if @melMass noticed any errors?

Right now it should run the following code whenever the window focus changes. Which I believe would not run on Mac.
Could someone try run this manually on Mac in Blender and see if this errors?

import ctypes

keycodes = [
	("_ALT", 0x12),
	("_CTRL", 0x11),
	("_SHIFT", 0x10),
	("VK_LWIN", 0x5B),
	("VK_RWIN", 0x5C),
	("OSKEY", 0x5B),  # dupe oskey, blender names it this
]

for name, code in keycodes:
	ctypes.windll.user32.keybd_event(code, 0, 2, 0)  # release key

[melMass]

Did it change recently?
I did not encounter any error besides that it always segfaults when closing blender (not sure if it's a Mac specific or not though)

[hannesdelbeke]

It didn't change, just surprised you didn't get any errors tbh.
The issue on closing also happens on windows.
Thanks for the quick reply :)

[hannesdelbeke]

tested myself on mac, and noticed bqt is completely broken.
one of the reasons is that the requirements dont include appkit and pyobjc

[hannesdelbeke]

after small fix where method was named with _ but called with __,
and manually installing the modules above with pip install iterm2 instead of appkit and pyobjc,
bqt now loads without crashing and wraps blender on mac
but it also freezes blender ...

Also on exit I get an error, just like on windows #47

TODO

• wrap blender without freeze
• instructions on how to install dependencies
• auto install dependencies based on different OS

[hannesdelbeke]

when I set the env var "BQT_DISABLE_WRAP" to 1, to disable wrapping, bqt seems to run great on Mac. see #66

[hannesdelbeke]

released some more fixes, since code broken when init on blender startup. likely some code functions different if startup is not finished yet. seems to be running alright now if wrapping is disabled

error

also running into this warning when creating a dock widget. repro 100%

• this error is also mentioned here brainglobe/brainrender#215

locall modules PySide2 5.15.2.1 (believe we only use this one)
Qt.py 1.3.8
Qt5.py 0.1.0

[melMass]

Honestly it was months ago so I could'nt tell, I feel like I would just have solved the issues you mention locally since they seem straightforward, but I think I would have specify it here (maybe not 😅)...

Anyway now my main driver isn't a Mac anymore but I can still test anything needed on an m1 laptop. Don't hesitate

[hannesdelbeke]

i wonder if perhaps you pip installed bqt on mac before we updated it on pip.
it was outdated for over a year on pip, and only a few months ago was updated
that version likely worked on mac.
