QMainWindow and saving positions of child widgets Qt : Qt 3.3.6
Message 1 in thread
Hi All,
I am working on an open source project called KWebTest.
I have lots of dockwidgets in a QMainWindow
I want the position of all the dock windows (ie child widgets) to be remebered
automatically upon application shutdown and want them to be restored when the
application starts again.
Can someone please tell me as to how it can be made possible?
Regards
Manish

Hi,
quoted from the Qt 3.3 documentation
(http://doc.trolltech.com/3.3/qmainwindow.html#details) :
To save the layout and positions of all the dock windows do this:
QFile file( filename );
if ( file.open( IO_WriteOnly ) ) {
QTextStream stream( &file );
stream << *mainWindow;
file.close();
}
To restore the dock window positions and sizes (normally when the
application is next started), do following:
QFile file( filename );
if ( file.open( IO_ReadOnly ) ) {
QTextStream stream( &file );
stream >> *mainWindow;
file.close();
}
I think creating a QTextStream for a QString
(http://doc.trolltech.com/3.3/qtextstream.html#QTextStream-3) and then
saving that QString using QSettings should work, but I don't have a Qt
3.3 installed to test it.
Regards,
Ralf

Call saveGeometry() on each of the dock widgets and on your main window,
and store each of them in QSettings. On loading, use restoreGeometry()
with that QByteArray.
You have to give your dock widgets object names for this to work.
