Option to maximize when there is only one window

[deleterium]

Hi! I know there is no big difference when the window is maximized or just resized to entire screen. But of course there is a difference in some applications. Some users may prefer to use the window maximized when there is only one!

My case is that I use another script for kwin named hide-titles ( https://github.com/bahamondev/hide-titles ). That script hides the title bar only when the window is maximized, but that script didn't work with this project...

I'm not pro in programming, but I solved this issue creating couple of lines, that add new config. I set it manually in kwinrc (I don't have knowledge to edit the .ui files and their control logic). So I just let the code here to make easier to implement this enhancement!

setMaximize doesn't appear to be a thing according to the docs, and as far as I know there never was a way to set maximize state from scripts.

I know it is strange, but I found setMaximize inside the code, file tilelist.js line 222 --- client.setMaximize(true, true); and it just works!

Oh, jesus, so the docs are now outright incomplete? Lovely.

My fault. I've added setMaximize to KWin back in 2019, but I completely forgot about the API docs.

I guess this belongs here since it's related and I didn't wanted to create another issue:
If you select the option to maximize window, it makes it wider and larger just to fit on the screen, but it's not really a "maximized" window per se, so the window doesn't make the panel adaptive opacity work and it doesn't apply the effect.
I tried to read the code base, but I didn't really find a way to do this from the script itself since I don't know js, I was thinking about making a qdbus call to really make it maximized, but as I said, I'm not able to fix it, so I'll leave my concern here
