i don't know if anyone's still following this thread, but i have run
into a nearly identical situation to the one described here. i have a
central widget which i always want to remain the same size, and dock
widgets that i want to stretch as the QMainWindow resizes
i have set the fixed size of the central widget accordingly and set the
sizePolicy and the vertical/horizontal stretch on the QDockWidgets to
every imaginable configuration and still when the QMainWindow is resized
it (at best) creates what i can only imagine to be dead space between
the central widget and the dock widgets (screenshot 1).
also of note is that when the dock widgets are then resized
(specifically when they are made smaller), the painting of the slider
bar as it moves through the large gray area seems to be buggy, as though
the background in that area is not being repainted (screenshot 2).
anyway, i'm hoping to not have to do anything too messy to fix this,
since it seems like a reasonable thing to want the QMainWindow to do,
but i'm pretty much open to any solution at this point.
thanks in advance,
jeff.

I wasn't able to fix it, so I am going to ditch this QDockWidget, I
think :D

ditching the QDockWidget sounds pretty nice, but unfortunately i think
i'm pretty stuck with using it in my application. it will eventually
need to display a whole lot of information, and having it all dockable
and closeable would make it much easier to organize and help to keep the
clutter down.
for anyone who's interested, here's a pretty basic demonstration of the
problem:
#include <QApplication>
#include <QDockWidget>
#include <QGroupBox>
#include <QMainWindow>
#include <QTextEdit>
int main(int argc, char **argv)
{
QApplication a(argc, argv);
// Main window
QMainWindow *mw = new QMainWindow;
// Dock widget
QDockWidget *d0 = new QDockWidget("Dock widget");
QWidget *w = new QWidget;
d0->setWidget(w);
d0->setMinimumSize(200, 200);
d0->setSizePolicy(QSizePolicy::Expanding,
QSizePolicy::Expanding);
mw->addDockWidget(Qt::RightDockWidgetArea, d0);
// Central widget
QTextEdit *te = new QTextEdit("Central widget", mw);
te->setFixedSize(400, 400);
mw->setCentralWidget(te);
mw->show();
return a.exec();
}
