Change background color of one menubar item eg Help in blue

[maulik_887]

Hello All,

I'm new to QT and I'm stuck at one point.
I have some of my menu bar items in right side (using this code http://qt-project.org/faq/answer/how...in_the_menubar). And I want the background color of those menu bar items will be blue/some icon.
Is this possible in QT ? If so then could anyone provide me a way to do so ?

Thanks in advance.

you can try something like this:

#include <QApplication>
#include <QMainWindow>
#include <QWidgetAction>
#include <QMenuBar>
#include <QMenu>
#include <QLabel>
#include <QStyle>
#include <QDebug>
 
int
main (int argc,
      char **argv)
{
    QApplication app(argc, argv);
    app.setStyleSheet("QLabel#label1 { background-color: blue }" \
                      "QLabel#label2 { background-color: yellow }");
 
    QMainWindow win;
 
    QLabel *label1 = new QLabel("Action1");
    label1->setObjectName("label1");
    QWidgetAction action1(&win);
    action1.setDefaultWidget(label1);
 
    QLabel *label2 = new QLabel("Action2");
    label2->setObjectName("label2");
    QWidgetAction action2(&win);
    action2.setDefaultWidget(label2);
 
    QMenu menu("Edit");
    menu.addAction(&action1);
    menu.addAction(&action2);
 
    win.menuBar()->addMenu(&menu);
    win.show();
 
    return app.exec();
}

#include <QApplication>
#include <QMainWindow>
#include <QWidgetAction>
#include <QMenuBar>
#include <QMenu>
#include <QLabel>
#include <QStyle>
#include <QDebug>

int
main (int argc,
      char **argv)
{
    QApplication app(argc, argv);
    app.setStyleSheet("QLabel#label1 { background-color: blue }" \
                      "QLabel#label2 { background-color: yellow }");

    QMainWindow win;

    QLabel *label1 = new QLabel("Action1");
    label1->setObjectName("label1");
    QWidgetAction action1(&win);
    action1.setDefaultWidget(label1);

    QLabel *label2 = new QLabel("Action2");
    label2->setObjectName("label2");
    QWidgetAction action2(&win);
    action2.setDefaultWidget(label2);

    QMenu menu("Edit");
    menu.addAction(&action1);
    menu.addAction(&action2);

    win.menuBar()->addMenu(&menu);
    win.show();

    return app.exec();
}

Thanks for the reply. Sorry, but it didnt help.

Let me describe my problem again. I want to have different colored "Menu Bar Items" not "Menu Item".
I have some Menu bar items like File, Edit etc in left site.. those will be in default color. And Some in right side say Help.. and that HELP itself should be in blue color(or have some BG image/style) not it's items(help->show help, Help->About).

Something like this..

Is this possible ?

This seems to be a hole in Qt. I didn't find a way to do that. Maybe it is possible if you reimplement QMenuBar or QStyle and provide your custom rendering. As a workaround I can propose you to use QToolBar instead of QMenuBar, where you can add labels or button via QWidgetAction and style them like in the sample above. With that approach you will have to display menu manually, but that should not be difficult.

Okay.. Will try to implement it as you suggested.

AFAIK you can change background color of all items in the menu bar but not some/specific items

QMenuBar:item { background-color: rgb(255, 37, 186); }

QMenuBar:item { background-color: rgb(255, 37, 186); }

To do what you want you would need to inherit from menu bar and paint it the way you want.
