Strange performance of QDockWindow?

[luffy27]

I have a MainWindow subclassed by QMainWindow, and also a QDockWindow on the bottom of the MainWindow. Then I add a QWidgetStack into the QDockWindow. The QWidgetStack contains two QHBox. Each QHBox is a toolbar. Finally, I want to switch on/off between the two toolbar by clicking a toolbutton, that is why I use a QWidgerStack in the QDockWindow.

However, despite of the swicth on/off functionality, the QDockWindow has a ridiculous presentation or performance, it can not show correctly!

Below is my code, Please Help Me!


#include <qapplication.h>
#include <qstring.h>
#include <qmainwindow.h>
#include <qdockwindow.h>
#include <qtextedit.h>
#include <qtoolbar.h>
#include <qtoolbutton.h>
#include <qpopupmenu.h>
#include <qwidgetstack.h>
#include <qhbox.h>
#include <qlayout.h>

toolBarStack->raiseWidget(0);

textEdit = new QTextEdit(this,"textedit");
textEdit->setTextFormat(Qt::PlainText);
textEdit->setFocus();
this->setCentralWidget(textEdit);
}

int main(int argc, char *argv[])

Wouldn't it be simpler to use regular toolbars? QToolBar inherits QDockWindow so you can use it just like a dock window and you can use show() and hide() to switch between toolbars without a widget stack.

[luffy27]

Is there any functions like show() or hide() supplied by QToolBar?
Ok, I will try it.

But by the way, I have solved the problem by adding this:
toolBarDockWindow->setWidget(toolBarStack);

Thanks a lot!

Yes, QToolBar inherits QWidget.

toolBarDockWindow->setWidget(toolBarStack);

Using show/hide will give you much cleaner code, especially if you use setShown()/setHidden() which are slots, so that you'll be able to connect them to actions that can trigger those changes.

All right, I will try it.
Thanks a lot!
