Hi
I am creating a WinMo application. I have a main menu which should
normally be displayed, but sometimes certain widgets want to display
their own menu content in the right menu. So I create a backup copy of
the main menu so I can restore it after any context sensitive menus has
been shown.
The very wierd thing is that when I make a backup of a menu item in a
sub QMenu, this QAction is always triggered multiple times and I do not
understand why. It only happens with Qt for Windows Mobile, it works
just fine in Win32. QActions not contained in a QMenu but directly in
the QMenuBar works just fine.
The minimal code to reproduce it is like below. What will happen is that
the QDialog in the slot will be displayed twice. It will open, you will
close it and then it will open again but only in Windows Mobile. I hope
I am doing it right and I am out of ideas so please, any ideas or
workarounds?
TestMenu::TestMenu(QWidget *parent, Qt::WFlags flags)
: QMainWindow(parent, flags)
{
ui.setupUi(this);
QMenuBar* originalMenuBackup;
//Clear the native menubar so we start from scratch
this->menuBar()->clear();
//1. Create the menu for the test
QMenu* debugMenu = new QMenu(tr("Test"),this);
debugMenu->addAction(tr("Item1"), this, SLOT(onItem1()));
this->menuBar()->addMenu(debugMenu);
//2. Make a backup copy of the original menu in 1 so we can restore
it later. If this is not done, everything works just fine
originalMenuBackup = new QMenuBar();
for (int i=0;i<this->menuBar()->actions().count();i++)
{
originalMenuBackup->addAction(this->menuBar()->actions()[i]);
//Something here must cause the triggered() signal to emit twice
}
//We are done, now just click on the Item1 button in the emulator
and the Item1 slot below will be called twice.
}
TestMenu::~TestMenu()
{
}
void TestMenu::onItem1()
{
QDialog dlg1;
dlg1.exec();
}
