Query regarding aboutToShow signal of Qmenu widget.

@Ratzz But that action will displayed as drop down of About. I don't want that I just when I click About it should display the dialog box irrespective if we click other menu items.

But that action will displayed as drop down of About.

Not sure what you have done & indented to do. If your intent is to show the dialog when you click on about action, as @Ratzz suggested, you can add three different actions & connection to slot. Inside the slot you can show any dialog you want. If not show the image of what you are planning to achieve.

@dheerendra I mean if I add action in About it will show context menu when I click on About.
Suppose I added Action About1 in About then when I click About it will show About1 as context Menu option. as per my understanding?

If not please let me know how can I add action and it should be not visible in UI and just clickin on About it will show dialog...how can i do this through programming

dheerendra

Add this in construction.
connect(ui->aboutAction,&QAction::triggered, this,&MyWidget::showAbout)

MyWidget::showAbout() {
// Create any dialog
// show it
}

You can connect signal/slot from Designer also. I'm showing you example from code.

@dheerendra I am using design view. And I do not want that action to be displayed in menu. Where and how should i create the action and attach to the about menu.

dheerendra

How are you adding the about menu option ? Can you tell ?

U can create an QAction to the menubar directly.
Your About menu will always be the last menu . Just try to add from code and connect to aboutclick()

@dheerendra I am adding through design view of QT.

@Ratzz Can I add QAction to the About menu using progamming even I if i am using design view

I think u can do in two ways
1)Using Code

 QMenuBar *m = this->menuBar();
 QAction *aboutMenu = new QAction("About");
 connect(aboutMenu, &QAction::triggered, this, &MainWindow::aboutclick);
 m->addAction(aboutMenu);

Using designer- Add an menu then connect to your slot

connect(ui->menuAbout,&QMenu::aboutToShow,this,&MainWindow::aboutclick);

You can do it. That is the code I wrote and showed you.
