Child window help
Message 1 in thread
I have a QtGui.QMainWindow that I want to spawn a configuration dialog
from. I have been trying many things and cannot seem to get it working.
What I have right now is a MainWindow created in QT-Designer, and a
Dialog created in QT-Designer. Both are separate UI files, and are both
included in the main program. So I guess before I tell you the million
ways I've tried it, How do I launch the child window with a Button? This
is a SDI, not a MDI interface. I have tried the windowflags example and
cannot even get that working.
Thanks,
Lawrence

There are several ways of applying a form to a QDialog instance
(see designer manual for details). Then you connect a slot to the
clicked signal of your button and in that slot you create the dialog and
call its exec() function.
If you need more detailed instructions please provide some example code.

Take a look to the MDI example:
http://doc.trolltech.com/4.2/mainwindows-mdi.html
good luck!
David.
this is important:
//mainwindow.cpp
class MainWindow : public QMainWindow
{
private:
QWorkspace *workspace;
};
//mainwindow.cpp
MainWindow::MainWindow()
{
workspace = new QWorkspace;
setCentralWidget(workspace);
}
void MainWindow::newFile()
{
MdiChild *child = createMdiChild();
child->newFile();
child->show();
}
MdiChild *MainWindow::createMdiChild()
{
MdiChild *child = new MdiChild;
workspace->addWindow(child);
return child;
}
