Qpushbutton drop-down menu (whether to cancel the drop-down triangle, check)

To add a menu to Qpushbutton, there are three ways ahead:

QT Learning to Qpushbutton add menu Actionscontextmenu method

QT Learning to Qpushbutton Add menu Customcontextmenu method

QT Learning to Qpushbutton add menu Defaultcontextmenu method

One more way today is to add a drop-down menu to Qpushbutton. Similar to a ComboBox. The first three ways to do this are where the cursor is located and where the menu is displayed. The drop-down menu is displayed only below the button, and the drop-down triangle appears, with the following effect:

To implement a drop-down menu, you first need to create a menu, action, and the button itself, in order to make it easier to display the effect, and add two member functions to display different information when the action is triggered:

M_menu = new Qmenu (this), m_addaction = new Qaction (m_menu); m_delaction = new Qaction (m_menu); M_addaction->settext ( Qobject::tr ("add")); M_delaction->settext (qobject::tr ("delete")); M_menu->addaction (m_addaction);m_menu-> Addaction (m_delaction), connect (m_addaction, &qaction::triggered, this, &buttonmenu::addfunc), connect (m_ Delaction, &qaction::triggered, this, &buttonmenu::d elfunc); M_pushbutton = new Qpushbutton (this); m_ Pushbutton->settext (QOBJECT::TR ("Test button menu"); M_pushbutton->setmenu (m_menu);//Settings menu

void Buttonmenu::addfunc () {qdebug () << "Addfunc";} void ButtonMenu::d elfunc () {qdebug () << "Delfunc";}

Compile run, there is a problem, Chinese characters garbled.

Because I am VS2013+QT, so solve the garbled problem in the header file add a sentence.

For the drop-down triangle icon on the button, you can cancel it by QSS if you don't need it:

M_pushbutton->setstylesheet ("Qpushbutton::menu-indicator{image:none;}"); /Do not display the drop-down picture

You can see that the small triangle does not show:

If you need an action click, there is a clear indication, that is, the state, as follows:

You only need to set qaction to check on it:

M_addaction->setcheckable (TRUE);//Can checkm_delaction->setcheckable (true);//can check

Finally, run successfully, click the corresponding action, you can see the console output:
