QMenu with tearoff enabled and with QWidgetAction

TheKodz

Implemented QMenu with QWidgetAction as one of the menu item along with many QAction's in it. Also enabled the tear off (setTearOffEnabled(true) ).

On executing the app and doing tearoff of menu, this QWidgetAction (which is a QLabel) is blank. Is this a bug in QT? If yes, is there any alternative to make the QWidgetAction visible?

Thanks.

Hi and welcome to devnet,

What version of Qt are you using ? On which OS ?

Can you share the code where you setup that menu ?

Thanks SGaist for replay.
I took the example itself from Qt : examples\activeqt\menus\main.cpp, menus.cpp

I updated menus.cpp and added following code:

QMenus::QMenus(QWidget *parent) 
    : QMainWindow(parent, 0) 
{
    QAction *action;

    QMenu *file = new QMenu(this);
    file->setTearOffEnabled(true);  //<= MY CHANGE

    action = new QAction(QPixmap((const char**)fileopen), "&Open", this);
    action->setShortcut(tr("CTRL+O"));
    connect(action, SIGNAL(triggered()), this, SLOT(fileOpen()));
    file->addAction(action);

    action = new QAction(QPixmap((const char**)filesave),"&Save", this);
    action->setShortcut(tr("CTRL+S"));
    connect(action, SIGNAL(triggered()), this, SLOT(fileSave()));
    file->addAction(action);
                                                                    //<= MY CHANGE
    file->addSeparator();                                           //<= MY CHANGE
    QWidgetAction* waction1 = new QWidgetAction(this);              //<= MY CHANGE
    QLabel*        label  = new QLabel("My Data");                  //<= MY CHANGE
    label->setAlignment(Qt::AlignHCenter);                          //<= MY CHANGE
    waction1->setDefaultWidget(label);                              //<= MY CHANGE
    file->addAction(waction1);                                      //<= MY CHANGE
                                                                    //<= MY CHANGE
    QWidgetAction* waction2 = new QWidgetAction(this);              //<= MY CHANGE
    QCheckBox*        chk  = new QCheckBox("Personal Data");        //<= MY CHANGE
    waction2->setDefaultWidget(chk);                                //<= MY CHANGE
    file->addAction(waction2);                                      //<= MY CHANGE

So, after tearoff, Label and checkbox are missing/hidden. Further I found following defect which looks to be not addressed yet.

I tried 4.8.6 and 5.5. Is there any way out for this?
