Gtk3 widgetset - call for testing

Zorin Os 18.1 is using GNOME 46.7 on Wayland.
Even after saving the settings, the IDE always starts with the windows centered and overlapping, as shown in the attached images.
It's a minor annoyance to rearrange these windows, but it doesn't interfere with the rest of my work each day.
The small projects I've tested so far also start centered even when they shouldn't, but then they work normally.

That's Wayland. It's garbage.

Yesterday I've fixed most of assertions from gtk3 css. Update your git and rebuild ide.

Would it be useful to attach the whole log of compiling messages?

Why are there so many Warnings and Hints' messages?

Should I compile Lazarus Trunk with FPC fixes_3_2 instead of FPC 3.2.2?

[zeljko]

gtk3 compiles with fpc-3.2.2 , fpc-3.2.4, trunk. Such messages like: "Parameter "cell_layout" not used" can be surpressed by disabling such fpc message...etc. , such like this:  Unit "LazPangoCairo1" not used in Gtk3CellRenderer will be cleaned up by me. For problem with compilation try to delete *.o and *.ppu inside lcl/units/YOURCPUANDOS/gtk3 , and then rebuild. It works here w/o problems.

Even the yellow tooltip that appears when the mouse hovers over the TButton in the IDE's Toolbar is anywhere far depending on which of the 5 Lazarus windows is selected when I hover the mouse over the TButton. See attached image.

When Lazarus 5.0 with LCL_GTK3 (current trunk) is released, will there be a notification stating that Wayland is not supported?

There will be notification stating that wayland isn't what an winapi based app expect (window positioning, querying x,y pos, window state changes). There are some trials with wayland to get some kind of window positioning via zones, and probably sending window state changes. Hints should work, and if they're misplaced then it is about wayland compositor implementation you use, not lazarus. Note that I have not problem with hints under weston or kwin-wayland. I know that you may be frustrated, but 90% of problems is not about lazarus implementation but different wayland compositors implementation.

Hi
Hahaha, I'm running both KDE 6.6.x & IceWM -- X11  ·  and IceWm doesn't give a toss about your placement specification... It puts your app in one of the four corners or dead center    KDE does what you tell it to do...
So, not just Wayland

Yes, just like it is written in basic x11 docs. Window manager decides about everything. Using KDE Plasma x11 for development, everything works fine here, xfwm4 also as I can see on my old laptop with Mint 20.03. Metacity have problems, but it's on it's way to be fixed. IceWM is still around ? Haven't play with it for 20 yrs.

[cdbc]

Hi zeljko
Yup, IceWM is still going strong and themes beautifully...
I actually switch to it when I'm programming/coding, 'cause it's so "Blitz-Schnell" -- no dead-wood to drag around -- plus if it runs there it'll run pretty much everywhere 
My old HP-lappy is loving it    Especially when I code with 'fpGUI' 
One minor bit is missing though -- I'll have to implement some app for DropBox & NextCloud, as they're refusing to "play ball" with IceWM... Someday I will

Thanks for your patience and effort.

Certification  processes exist for many reasons, mainly for cost and training time.

I am studying alternatives to minimize the impact.

Tampering with the certified end-user environment is always more traumatic and more expensive than limiting programmers and network administrators.

Well, great, progress is being made with Wayland Zones -

https://www.phoronix.com/news/Wayland-Experimental-Zones

All we need to wait for now is it to make it through to a practicable release and Gnome to take it up. Gnome apparently is accused of cherry picking only the new things it likes and the industry just seems to follow Gnome, unquestioningly.

Sorry, for those not unduly excited about Wayland, Zones is apparently some add on protocol that will allow an application to position a window where it wants to instead of the centre of the screen. But who would want that ?

Now, do we wait for Zones to be accessible cutesy of GTK4, 5 or 6 or what ever or do we consider a 'zones' unit that can make those calls in Pascal ?  For example, I call direct to X to change workspaces (but obviously fails in wayland).

Well, great, progress is being made with Wayland Zones -

https://www.phoronix.com/news/Wayland-Experimental-Zones

All we need to wait for now is it to make it through to a practicable release and Gnome to take it up. Gnome apparently is accused of cherry picking only the new things it likes and the industry just seems to follow Gnome, unquestioningly.

Sorry, for those not unduly excited about Wayland, Zones is apparently some add on protocol that will allow an application to position a window where it wants to instead of the centre of the screen. But who would want that ?

Now, do we wait for Zones to be accessible cutesy of GTK4, 5 or 6 or what ever or do we consider a 'zones' unit that can make those calls in Pascal ?  For example, I call direct to X to change workspaces (but obviously fails in wayland).

Zones will be available imediatelly for any lazarus WS that supports wayland. Zones primary usage is to restore window positions (not exact x,y but zones) at next application start.

Yet not a solution per se, but still interesting:
