CudaText doesn't start if you disable the window frame (Linux).

[VicDobrov]

Window manager: kwin If you disable the window borders (create a rule - without borders), the editor does not start. It is sad…

What linux distro do I need, to not break my Ubuntu ? How to setup kwin in it? How to turn off border?

[Alexey-T]

Pls test this simple dialog app http://uvviewsoft.com/c/testmsgboxes.zip it if don't work too, we have lazarus gtk2 bug.

I tested it, everything is fine! Created rules that disable the window frame. Launched the dialogue - all the dialogue normally displayed without a frame.

The rule the kwin Window manager: "Hide the title and border of a window" Force

If you create a similar rule for CudaText, the program will not start. It will be the maximum load of one processor core… Perhaps the reason for the hang is that the editor remembers the geometry of its window itself.

Any Linux (I have Arch Linux). file: $HOME/.config/kwinrulesrc [$Version] update_info=kwinrules.upd:replace-placement-string-to-enum [1] Description=Settings testmsgboxes clientmachinematch=0 noborder=true noborderrule=2 title=StrCaption titlematch=1 types=32 wmclass=testmsgboxes wmclassmatch=1 [2] Description=Settings testmsgboxes clientmachinematch=0 noborder=true noborderrule=2 title=Test for various message-boxes titlematch=1 types=1 wmclass=testmsgboxes wmclassmatch=1

I don't know how to build from sources. ;-(

Instructions on how to disable the window frame for 1) copy the rules file, the text of which I gave earlier: $HOME/. config/kwinrulesrc 2) Install Desktop Environment: plasma or LXDE or LXQt 3) run "Default applications for LXSession"for LXDE. For LXQt, run Session Settings. 4) select kwin_x11 as the window Manager 5) launch the program, press Alt+F3, select the submenu item: Window parameters. 6) add a rule: Hide the title and borders of the window 7) select the launch type For this rule: «Force» 8) close the app and start it again...

The point is for the window Manager to load rules that allow the application to run without a window frame. The rules are supported by many window managers: openbox, awesome, icewm, and many others…

If you will get Lazarus, test the issue on it, pls?

[VicDobrov]

Test results — Lazarus IDE with the window frame forcibly disabled runs without errors.

[Alexey-T]

Hm, so I need to test it myself.. pls wait.

[VicDobrov]

A small addition: Linux window Manager (such as kwin) searches for rules for a specific application's window class, such as Cuda Test As a result, the Cuda Test window is created immediately without the window frame, if the option is available: noborder=true

[Alexey-T]

sorry, no time to test this: I will need to install new Linux (easy) and follow config steps (hard for me), and install fpcupdeluxe, and compile CudaText.

CudaText compile info: https://wiki.freepascal.org/CudaText#How_to_compile_CudaText

no time to test/setup this.
