Re: [bugs #11713] Windows resizable when they shouldn't be

[Fred Kiefer]

Hi Alex,

would you mind to put further replies into the Savannah entry? This will 
make it a lot easier to track a bug report later on.

No, I don't think my questions where overanalytical. We first have to 
agree on when we expect a window to be non resizable and than agree on 
the way to implement it.
From what I understand from your mail your position on the first 
question is that a window should be non-resizable when you think it 
should not be resizable. This is a bit hard to implement. You probably 
mean that some other window manager (perhaps Window Maker?) treats this 
windows as non-resizable and you would like other window managers (the 
one from Gnome) to do the same. But this just brings us back to my first 
question: Why does the first window manager know that the window is not 
resizable? As far as I can tell window managers treat windows with 
minSize and maxSize both set to the window size as non-resizable. If you 
find a window manager where this is not the case, we should analyse the 
behaviour and find a workaround.
Now Gorm panels are resizable for me (on KDE) and I think this is 
because maxSize is not set there (and actually I am glad that this is 
the case).

Sorry, this was a real question. Are windows with the flag missing 
expected to be non-resizable? The Apple documentation is not clear on 
this (it just talks about resize hints not being displayed). If this is 
an expected behaviour, we need to implement it. But there are at least 
two ways to do so. Either we make sure that for windows without this 
flag, minSize and maxSize (on NSWindow) always stay the same as the 
frame size (which would happen in GUI) or we leave these values alone, 
but pass on the actual size as max and min size as window manager hints 
in the backend. Both ways are very easy to implement, but we should make 
an educated decisson first.
That's why I started asking questions. Implementing something that seems 
to work in some conditions is fairly easy, but implementing the correct 
thing may require some testing. Actually I prefer to have the correct 
thing implemented.

Cheers
