Have you try using the @void setWindowFlags ( Qt::WindowFlags type )@

Its the correct function, the usage is the following:

"QWidget::setWindowFlags":http://doc.qt.nokia.com/latest/qwidget.html#windowFlags-prop
"Qt::WindowsFlags":http://doc.qt.nokia.com/latest/qt.html#WindowType-enum

@
MyDialog::MyDialog(QWidget* pParent) :
QDialog(pParent, Qt::CustomizeWindowHint | Qt::WindowTitleHint | Qt::WindowMinMaxButtonsHint )
{
}
@

I don't remember if you have any flag to dissable the close button, but in that scenario, you could apply the:
Qt::FramelessWindow
Flag in the initialization of the QDialog parent, and that will allow you to dismiss the NonClient Area (titlebar, the window borders), in that case you have to provide a way to close the window.

Regards!

FramelessWindow removes the complete frame

Qt::CustomizeWindowHint says: i say what to display. If you don't set Qt::WindowSystemMenuHint or Qt::WindowCloseButtonHint, the close button should be away but you have a title bar, window frame etc.

I think this removes only the close button

@dialog->setWindowFlags( ( (dialog->windowFlags() | Qt::CustomizeWindowHint)
& ~Qt::WindowCloseButtonHint) );@

no it removes everything, also max and min button.
windows flags does not contain min/m ax hint by default, as they are only needed if Qt::CustomizeWindowHint is used.

Thanks, your methods is fantancy. But's a little flaw. the Min button and Max button not hint.

giesbert

if you don't want m in/max button, remove them from the flas.

@giesbert said in How to hide the dialog window close button?:

if you don't want m in/max button, remove them from the flas.

You mean like this?
: QDialog(parent, Qt::CustomizeWindowHint | Qt::WindowTitleHint )
That does not work, the min/max buttons, i.e. the small arrows on the right hand side, are still there. I have tried various combinations of flags, but I cannot get rid of those arrows. I don't want to remove the top panel.
