CenterOnScreen not working for FixedSize Window

[scorpione71]

Describe the bug:

Good evening. I have some problems found after updating Fyne V. 2.0 to Version V. 2.1. The fields of the struct Label "Alignment fyne.TextAlign" and "TextStyle fyne.TextStyle", which worked perfectly with V. 2.0, do not work after the update to V. 2.1. Another problem, the "CenterOnScreen ()" function, which should place the window in the center of the screen, which worked before the update, with the new version, unfortunately it positions the window lower and to the right of the center of the screen. I hope that these problems that I have encountered can be solved, and in any case, I take advantage of the opportunity to compliment the excellent work done.

We prefer to have one bug report per issue because it is much more clear (especially if a PR is aiming to fix one issue but the issue remains open afterwards because the other bugs in the issue are not fixed). It would be great if we could get working, minimal code examples for reproducing issues (no screenshots of code please and not parts of code).

After editing properties of a widget you need to call Refresh. You can get this behaviour back by making the SetText the last call in your function as it will refresh and apply all the settings you have made.

Thank you for answering. It was very useful. If you find a solution for the CenterOnScreen() function as well, please let me know. Thank you very much for the attenzione. Il ven 15 ott 2021, 15:16 Andy Williams ***@***.***> ha scritto:

I cannot replicate the center on screen issue, perhaps it is Linux (Mint?) specific.
Can you provide more details about the desktop / window manager so we can replicate?

Maybe the center on screen is not a real issue.
If it can help, I noticed that this also happens to me but only when I activate the second monitor.
Using just one display the window is correctly centered on the screen.

$ hostnamectl
  Operating System: Debian GNU/Linux 11 (bullseye)
            Kernel: Linux 5.10.0-9-amd64
      Architecture: x86-64

$ cat /usr/share/gnome/gnome-version.xml
<?xml version="1.0"?>
<gnome-version>
  <platform>3</platform>
  <minor>38</minor>
  <micro>5</micro>
  <distributor>Debian</distributor>
</gnome-version>

Using just one display the window is correctly centered on the screen.

When there is a second screen active where does the window appear?

[lucasepe]

It appears a little bit moved to the lower right corner (do you want me to run a snippet with a fixed size window and post the screen shots?)

[andydotxyz]

That could be helpful thanks. There a couple of different ways the positioning could be off and seeing it will help.

[lucasepe]

I have to correct myself, doing more experiments I noticed that regardless of number of monitors the window is not centered when the w.Resize(...) command is given (calls order does not make difference).

I have attached an animated gif showing that using w.Resize(...) the window is no longer centered (btw: I'dont think it's a big issue...users move windows all the time).

Fixed in v2.1.2

[scorpione71]

Good evening, thanks for the information. I'll keep practicing with Fyne. I think he has already reached a good maturity, I hope that many more tools will be introduced in the future. Good job. Il giorno mar 7 dic 2021 alle ore 01:12 Andy Williams < ***@***.***> ha scritto:
