Actors selection in Atlas not working

[cephalotus]

It seems that since the release of A27, selecting actors in Atlas using Alt+Select (as usual) doesn't work at all. I was searching a bit and I didn't find anyone discussing the problem, so my question is if this is a known issue or I'm missing something. It's pretty unfortunate, because I'm unable to make my own maps currently. I tested it on two computers, both running on Linux Manjaro, and it's not working on either of these, but it worked on A26. The recent patch release didn't fix the issue.

It is not a known issue as far as I am aware so thanks for reporting. Could be because arch and manjaro use sdl3 rather than sdl2. Maybe @hyperion can reproduce

Hello @cephalotusmind if you help with some information regarding your  Linux Manjaro, im not sure what version of wxWidget you have there, can you tell me about it?

 

why?: the Atlas Editor relay on wxWidget to capture keyboards keys, so maybe can be related to a bug or kind of wxWidget but i would like to discard if this is the issue first

Sure thing, this should be what you are asking for:

Name            : wxwidgets-gtk3
Version         : 3.2.8.1-2

i would like to ask you two additional things:

1. An screenshot that show me the whole AtlasUI when you tried to click or select an actor

2. Maybe if you can record and upload the record to see what steps are you using to being able to catch any minimal detail that drive me to found the real issue

thx

I can reproduce it with system wx.

If I build wx from source without the make it work for both x11 and wayland hacks the distribution adds the alt key starts working again. Instead it it triggers another issue with our code which makes Atlas useless. Namely wxGetKeyState is only usable for modifier keys with that codepath.

Will have to think more about how to go about it. There is also wx 3.4 in the making which likely will solve the x11 vs wayland issue (glcanvas) but trying to build against wx 3.3 fails, so atlas needs fixing for that as well, don't know yet how much work it would be yet.

TLDR, not something fixed in a few minutes.

So there are now:

https://gitea.wildfiregames.com/0ad/0ad/pulls/8293

https://gitea.wildfiregames.com/0ad/0ad/pulls/8294

https://gitea.wildfiregames.com/0ad/0ad/pulls/8295

This allows to use GTK on pure Wayland builds of wxWidgets where "Alt" works as expected and the others are in preperation for wxWidgets 3.3/3.4.

 

The cause for the "alt" issue root lays in https://github.com/wxWidgets/wxWidgets/issues/22325 , guess we could work around it by directly depending on gtk (which I rather not) or check if it's possible to upstream a patch.
