[Solved] Display QMainwWindow and QMdiArea

Franzk

QMdiArea::addSubWindow() returns a QMdiSubWindow. Do your resizing on that instead of the QWidget. You can probably also set the size of the widget before you add it to the mdi area. That will initialize the QMdiSubWindow with the correct size.

mbynet

please post example

@void MainWindow::spShShow()
{
QWidget *wgt = new QWidget();
wgt->resize(200,200);
mdiArea->addSubWindow(wgt);
wgt->show();
}

dont work too

Franzk

Untested but most likely to work:
@QWidget *w = new QWidget;
QMdiSubWindow *sw = mdiArea->addSubWindow(w);
sw->resize(200,200);
sw->show();@

i use this example, dont work. sw - show max window.

This works as expected:

@

#include <QApplication>
#include <QMainWindow>
#include <QMdiArea>
#include <QMdiSubWindow>
#include <QTextEdit>

int main(int argc, char **argv)
{
QApplication a(argc, argv);

QMainWindow mw;
QMdiArea *mdi = new QMdiArea(&mw);
mw.setCentralWidget(mdi);

QTextEdit *te = new QTextEdit;
QMdiSubWindow *sw = mdi->addSubWindow(te);
sw->resize(300,100);
sw->show();

mw.show();
a.connect(&a, SIGNAL(lastWindowClosed()), &a, SLOT(quit()));
return a.exec&#40;&#41;;

}

BTW: Are you sure you call the right function?MainWindow::spClientShow() always shows your new Window maximized!

question another!!!!

@#include <QApplication>
#include <QMainWindow>
#include <QMdiArea>
#include <QMdiSubWindow>
#include <QTextEdit>

int main(int argc, char **argv)
{
QApplication a(argc, argv);

QMainWindow mw;
QMdiArea *mdi = new QMdiArea(&mw&#41;;
mw.setCentralWidget(mdi);

QTextEdit *te = new QTextEdit;
QMdiSubWindow *sw = mdi->addSubWindow(te);

// sw->resize(300,100);
sw->showMaximized();

QTextEdit *ti = new QTextEdit;
QMdiSubWindow *sb = mdi->addSubWindow(ti);
sb->resize(300,100);
sb->show();

mw.show();
a.connect(&a, SIGNAL(lastWindowClosed()), &a, SLOT(quit()));
return a.exec(&#41;;

}

How Display QTextEdit *ti size(300,100)??? *ti Display Maximized. If push minimize 2 windows minimize and *ti take size 300,100

You must call

@
mdi->setOption(QMdiArea::DontMaximizeSubWindowOnActivation, true);
