showMaximized in MDI

[walito]

Hi!!

Im preoblem using MDI and subwindow.
The problem is when use showMaximized(), setWindowFlags(Qt::WindowTitleHint) not found.

But I use show() setWindowFlags(Qt::WindowTitleHint) remove button OK.

Where is de problem?

The code is:

QMdiSubWindow *subWindow1 = new QMdiSubWindow(this);
    subWindow1->setWindowTitle(tr("ZZZZ"));   
 
    subWindow1->setWindowFlags(Qt::WindowTitleHint);
    subWindow1->setAttribute(Qt::WA_DeleteOnClose);
    subWindow1->setWidget(new QPushButton("xxx"));
 
    mdiArea->addSubWindow(subWindow1);    
    subWindow1->showMaximized();
    //subWindow1->show();

QMdiSubWindow *subWindow1 = new QMdiSubWindow(this);
    subWindow1->setWindowTitle(tr("ZZZZ"));   
    
    subWindow1->setWindowFlags(Qt::WindowTitleHint);
    subWindow1->setAttribute(Qt::WA_DeleteOnClose);
    subWindow1->setWidget(new QPushButton("xxx"));
    
    mdiArea->addSubWindow(subWindow1);    
    subWindow1->showMaximized();
    //subWindow1->show();

Maximized windows don't have titles. Their title is shown on the viewport's title bar.

Sorry, the correct line is:

subWindow1->setWindowFlags(Qt::Window | Qt::CustomizeWindowHint);

subWindow1->setWindowFlags(Qt::Window | Qt::CustomizeWindowHint);

This would make the mdi child a top level window, but that wouldn't make any sense, would it? What are you trying to achieve?
