Menu bar does not show up

[SahamGhazavi]

Hi

I am following tutorials on youtube. My form has Manu bar and toolbar. I have created one menu named File and under that I have submenu called New Window. I also added actionNew_Window to the toolbar. When I run the program, the toolbar is there but I dont see my menu.

Any idea?

Thank you

It is very strange if example not works as expected. Did you make any changes in code from example?

[SahamGhazavi]

Nope. I even started the new project and just created one File menu with no submenu. Still does not show up when I run it!!

Check if the menu bar is visible with the isVisible() function. You never know

[SahamGhazavi]

There is not visible property for the menu bar or I cannot find it.
I even add this on main window constructor:
ui->menuBar->setVisible(true);

but didnt help

[raf924]

There is : ui->menuBar->isVisible()
Just out of curiosity : what version of Qt are you using?

[SahamGhazavi]

Qt Creator 2.7.0
Based on Qt 5.0.2 (64 bit)

isVisible() just checks for visibility but I wanted to set the visibility :)

[SahamGhazavi]

If the following always puts NO in the text filed
if(ui->menuBar->isVisible())
ui->plainTextEdit->setPlainText("YES");
else
ui->plainTextEdit->setPlainText("No");

Can you post your project?
