Hi all,
I am using Qt(C++) to develop an IOS app. When I use a QMenu without parent
on a modal dialog, the menu gets hidden behind the dialog. This issue does
not happen if I set the modal dialog as parent. Upon debugging in Qt, I
noticed that the window level of a menu (Qt::Popup) is lower than of a
modal dialog. Is this window level correct or is it a bug? What will be the
correct way for me to fix this issue if I do not want to create the menu
without a parent.?
Example code in my blocking dialog:
> m_Button = *new* QPushButton(m_ButtonFrame);
> m_Button->setText("Test Menu");
>
> QMenu* menu = *new* QMenu();
> QAction* act = menu->addAction("Test0");
> menu->addAction("Test1");
> menu->addAction("Test2");
> m_Button->setMenu(menu);
Qt's code in question:
> void QIOSWindow::updateWindowLevel()
> {
> Qt::WindowType type = window()->type();
> if (type == Qt::ToolTip)
> m_windowLevel = 120;
> else if (window()->flags() & Qt::WindowStaysOnTopHint)
> m_windowLevel = 100;
> else if (window()->isModal())
> m_windowLevel = 40;
> else if (type == Qt::Popup)
> m_windowLevel = 30;
> else if (type == Qt::SplashScreen)
> m_windowLevel = 20;
> else if (type == Qt::Tool)
> m_windowLevel = 10;
> else
> m_windowLevel = 0;
> // A window should be in at least the same m_windowLevel as its
> parent:
> QWindow *transientParent = window()->transientParent();
> QIOSWindow *transientParentWindow = transientParent ?
> static_cast<QIOSWindow
> *>(transientParent->handle()) : 0;
> if (transientParentWindow)
> m_windowLevel = qMax(transientParentWindow->m_windowLevel,
> m_windowLevel);
> }
Thanks in advance.
Regards,
Sivan
