window.Resize() does not work if SetFixedSize(true) is set after

[FredPont]

Describe the bug:

In Fyne 2.1.3 the order of window.Resize() and SetFixedSize(true) matters. This is not the case in Fyne 2.1.2

To Reproduce:

This code only works on Fyne 2.1.2. On Fyne 2.1.3, it does not resize the window w which appears minimized :

w.Resize(fyne.NewSize(finalWidth, finalHeight)) 
w.SetFixedSize(true)

Whereas this code works perfectly

w.SetFixedSize(true)
w.Resize(fyne.NewSize(finalWidth, finalHeight)) 

Device :

• OS: Linux Manjaro
• Version: up do date 2022-03-04
• Go version: go1.17.6 linux/amd64
• Fyne version: 2.1.3

May or may not be related to #2800, another window resize/fixedsize related regression

[andydotxyz]

Thanks for connecting the two, but #2800 isn't a regression as far as I know, the initial size of an image using FillOriginal has always been off, it corrects on the second draw. Normal windows then adjust accordingly but FixedSize windows don't. It too needs fixed, but this regression is much higher priority.

[kheyse-werk]

it is a regression because in 2.0 the same code works without problem.
but we should probably discuss that on that issue.

I cannot replicate on macOS, this may be Linux specific which could explain why it was missed I guess.
Window sizing is one of the most complex code paths :(.

[andydotxyz]

I cannot replicate on Debian/FyneDesk either. Can you please provide more info about the failing WM and desktop setup @FredPont ?

[andydotxyz]

This may also depend on the content of the window I guess - the excerpt provided may not be enough to replicate.

I did the test on 3 computers with XFE 4.16.
computer 1 & 2 Linux manjaro
computer 3 : Xubuntu 21.10

I reproduce the issue on the 3 computers with my software based on Fyne. In this software, the window content is a multilayer scroll image with a PNG picture, an interactive raster, and containers for drawing. It is thus difficult to build a toy program with this structure (maybe it could be reproduced with pixel editor).

type Editor struct {
	drawSurface                     *interactiveRaster
	microscop                       *canvas.Image
	min                             fyne.Size 
	layer                           *fyne.Container 
	win                             fyne.Window
	gateContainer                   *fyne.Container
	gateNumberContainer             *fyne.Container
	gateDotsContainer               *fyne.Container
	clusterContainer                *fyne.Container

}

the final window content is :

e.layer = container.NewMax(e.drawSurface, e.microscop, e.clusterContainer, e.gateContainer, e.gateDotsContainer, e.gateNumberContainer)

w.SetContent(container.NewScroll(e.layer))

Please note that the 3 computers use a Nvidia card.

I did the test on 3 computers with XFE 4.16.

Maybe it is specific to that WM?

Is it possible to replicate the problem with a minimal example, that will be very helpful.
For example a small modification to the hello world example?

[FredPont]

@andydotxyz ,

I send you a zip file with a minimal example to reproduce the issue and a video showing that, depending on the position of w.SetFixedSize(true), the fyne window is minimized or not.

Thanks, verified with this code - it seems that some content triggers it and others don't

[andydotxyz]

If you get a chance please test #2829 - I think it resolves this issue

[andydotxyz]

Fixed in v2.1.4 under vote now
