Remove native Mac menu items such as Show Tab Bar

[ArmanSom]

It seems that the action - Show Tab Bar - automatically inserts itself into the View menu that I create.

I would like to keep the menu named as is. Is it possible to remove the system menu action through the Qt API? If not, may I have suggestions for non-Qt solutions?

Thank you,
Arman

Hi and welcome to devnet,

If you don't have any tool bar then you can use QMainWindow::setUnifiedTitleAndToolBarOnMac.

Hope it helps

According to this topic : how-do-i-disable-the-show-tab-bar
you need to call:
[NSWindow setAllowsAutomaticWindowTabbing: NO];

For doing that, you have to create a C++ class (named CocoaBridge here) with .mm extension.

Add it to your .pro file:

macx{

HEADERS +=		CocoaBridge.h 
OBJECTIVE_SOURCES +=	CocoaBridge.mm

 LIBS +=		-framework AppKit
}

The C++ class looks like this:

#ifndef COCOABRIDGE_H
#define COCOABRIDGE_H

class CocoaBridge
{

	CocoaBridge() {}

	public:

    static void setAllowsAutomaticWindowTabbing(bool flag);

};

#endif // COCOABRIDGE_H

and CocoaBridge.mm :

#include "CocoaBridge.h"
#import <Cocoa/Cocoa.h>

void  CocoaBridge::setAllowsAutomaticWindowTabbing(bool flag)
 {
	[NSWindow setAllowsAutomaticWindowTabbing: flag];
 }

Should work ...
