If you set the enclosing Widget size policy to Fixed, then it should use the
minimum required for its layout anyway. You can also play with the
layout's size constraint property.

Hi thanks
Another way is to use QToolButton instead of QCheckBox.
For each button do something like this:
QIcon Icon;
QPixmap pm(":/images/off.png");
QPixmap pmSelected(":/images/on.png");
Icon.addPixmap(pm,QIcon::Normal,QIcon::Off);
Icon.addPixmap(pmSelected,QIcon::Normal,QIcon::On);
QToolButton

Hello. I'm trying to produce a layout similar to the attached, where
nine radio buttons are set out in a 3x3 cluster. I am producing the

On Mac I *think* everything under /Volumes can be considered mounted (not sure
about network/NFS mounted drives though).
But I'm sure there's a more reliable API to query that.

Hi List.
Is there a way to get a list of currently mounted network volumes? Or

I thought QDir::drives() is it but it returns only the root (/) on Mac
and drive letters on Windows. I am looking to get the names of the
server volumes.

Very much likely ;) My book sais that "LLVM 3.0 / Clang" did not become the
default until Xcode 4.2 - For Xcode 3.2
Just another data point:

Regarding this problem, I've found a way around. It is a nasty way

I've added some warnings, and adding a new variable, a QStringList

QStringList sons = s.childGroups();
In the loop, I check if a group exists, with a call to QSettings

375% CPU utilisation, so a -j4 would be recommended.

In QtCreator it uses "Make" to do the compile and by default it will only use a
