Qmenu::findChild is not working properly

Qt Enthusiast

Hi All
The QMenu findChild is not working properly

QMenu* lMenu;
QMenu* existingMenu = lMenu->findChild<QMenu*>(QString("A..."));
if (!existingMenu)
lMenu->addMenu("A...");

Can someone help me to solve the same . In this case existing menu is always NULL athat is why A... gets added multiple times

findChild

the string you define in findchild specifies the objectname. Newly, by code not designer, created Objects have an empty string as ObjectName.

untested.

QMenu* lMenu;
QMenu* existingMenu = lMenu->findChild<QMenu*>(QString("A..."));
if (!existingMenu){
     existingMenu  = new  QMenu("A...");
     existingMenu->setObjectName("A...");
     lMenu->addMenu(existingMenu);
}
