#49 Initial painting yields "stretched" look

[Geoff Hutchison]

Particularly on my Mac, when I launch, the first painting of the GLWidget yields a "stretched" look (see attachment).

Resizing the window results in a normal look to the render.

Perhaps the initial GLWidget (or somewhere along the render chain) is assuming a particular window size? Avo has saved my preference for a large window.

Please try the attached patch, which adds a call to resizeGL() at the end of initializeGL().

No, it doesn't seem to work.

Strangely, I also don't seem to save the window size on quit. I don't know if these are related. Can you reproduce the problem, or is it only my machine?

Hm, then revert the previous patch and apply the new one.

Here (Kubuntu, qt-copy from KDE trunk) the window size is properly saved and restored. I don't know if that can be related.

That seems to fix it, although I'm not going to close the bug yet -- I'd like to figure out why my Mac isn't saving the window preferences.

OK, committed.

I have no clue why the Mac isn't saving the window preferences, though. But I understand that the fact that it restores the window size on some platforms means that resizeGL is automatically called on those platforms, which might explain why the two issues might be related.

I am re-opening this bug. I think it is due to when the GLWidget is created and when the MainWindow is shown. Particularly due to "delayed initialization". I was having a problem with my first GLWidget (View 1) being slow when i first started Avogadro until i resized the GLWidget, then it ran normal. I tracked the bug down to the fact that the MainWindow wasn't being ::setVisible until AFTER i had created the GLWidget or loaded settings. This is something that shouldn't be an issue but it is for some QT4 behind the scenes reason (or that's what i chalk i up to). So i have changed the order to:

Load a File
Show MainWindow
Read MainWindow settings (creates GLWidgets etc)

This way the MainWindow only becomes visible when it's ready to be used. It's not that long of a delay so there is no reason for a splash screen.

Geoff, this is assigned to you as I would ask that you comment the line that Benoit provided: GLWidget.cpp:728 and see if this resolves your stretch issue.

No. Without Benoit's fix, I get a "stretched look."

I'm marking this bug closed. If we want to talk about this issue, let's open another bug thread, because what you're discussing is a new question.
