Hi
Well docs says
"Note: Creating a main window without a central widget is not supported. You must have a central widget even if it is just a placeholder."

@mrjj said in can i donot setCentralWidget in QMainWindow?:

placeholder

placeholder? simply setCentralWIdget(new QWidget())?

[mrjj]

@opengpu
yes.

[opengpu]

QWidget* pCentralWidget = new QWidget(this);
//pCentralWidget->setVisible(false); //which is better?
//pCentralWidget->setFixedSize(QSize(0,0)); //which is better?
setCentralWidget(pCentralWidget);

[opengpu]

@mrjj //which is better?

Hi
well what do you try to do ?
i would say setVisible(false); if you try to hide it.

Normally all other widgets live in CentralWidget
so its odd if you want to hide it.

@mrjj i want all the Widgets are dockwidget

I would support a central widget by implementing drag-n-drop of docks into the center and vise versa.

Normally all other widgets live in CentralWidget? but i think the DockWidget is in the MainWindow which is their parent.

Hi
Yes dockwidgets do live outside central. (around it)
I mean other widgets. But if you dont need it, i guess only docks are fine :)
