MainWindow doesnt show MenuBar

JonB

@medyakovvit
Won't he need setMenuBar(sb) for his main window too?

Vadik

@medyakovvit Already tried this, and many of other combination "removing-adding". No one helps

JonB

@Vadik
So you've tried this?

QMenuBar *mb = menuBar();
mb->addMenu(file);
this->setMenuBar(mb);

@JNBarchan said in MainWindow doesnt show MenuBar:

QMenuBar *mb = menuBar();
mb->addMenu(file);
this->setMenuBar(mb);

yes, have tried, and the same code is working on other machines.

JonB

@Vadik
Oh, this is the first time you're saying the code works on some machines and not others?

Vadik

@JNBarchan yeah, I just forgot, allready corrected. Thanks for reminder.

JonB

@Vadik
So I would look at exactly what version of Qt libraries is being used on your machine versus other machines? Maybe they have a later version than your 5.5, and it will work then?

Vadik

@JNBarchan Allready reinstalled Qt up to 5.9.2 version. And still didn't help

Hi,

Aren't you on Ubuntu ? If so, isn't your menu bar shown at the top of the screen macOS like ?

JonB

@SGaist
LOL if that's what OP means. I have my desktop preference set to show menus on windows, but the default is on system menu.

@Vadik YEEEEAH, solved, after some investigations and reinstalling of all components it turned out. Need to change in 'System Settings -> Appearance -> Behavior' parameter for 'Show the menus for a window' from the "In the menu bar" to "In the window's title bar". Thanks to everyone who tried to help.

@JNBarchan Question is solved, but as you asked.
I don't think it's needed as he gets pointer to menu bar with:

QMenuBar *mb = menuBar();

and this function returns the menu bar that already set.

JonB

@medyakovvit
Yeah, I kinda mis-read (C++ not being my language) it as having been:

QMenuBar *mb = new QMenuBar();

thinking he was creating his own new one which would need setting. Using the existing menubar and changing its content is of course preferable.
