[anupamgee]

hi all,
i want to change the background color of Qmenu.
i tried the following code:

TabWindow::TabWindow(QWidget *parent) : QWidget(parent)
{
    QMenu  *menu=new QMenu(this);
    onlineAct = new QAction(tr("Online"), this);
    busyAct = new QAction(tr("Busy"), this);
    menu->addAction(onlineAct);
    menu->addAction(busyAct);
    connect(onlineAct,SIGNAL(triggered()),this,SLOT(online()));
    connect(busyAct,SIGNAL(triggered()),this,SLOT(busy()));
   menu->setAutoFillBackground(true);
   QPalette palette=menu->palette();
   palette.setColor(QPalette::Window, Qt::blue);
   menu->setPalette(palette);
}

TabWindow::TabWindow(QWidget *parent) : QWidget(parent)
{
    QMenu  *menu=new QMenu(this);
    onlineAct = new QAction(tr("Online"), this);
    busyAct = new QAction(tr("Busy"), this);
    menu->addAction(onlineAct);
    menu->addAction(busyAct);
    connect(onlineAct,SIGNAL(triggered()),this,SLOT(online()));
    connect(busyAct,SIGNAL(triggered()),this,SLOT(busy()));
   menu->setAutoFillBackground(true);
   QPalette palette=menu->palette();
   palette.setColor(QPalette::Window, Qt::blue);
   menu->setPalette(palette);
}

To copy to clipboard, switch view to plain text mode 

but the color is not changing.It is showing white background color.
what to do??

you can set style sheet using this method QWidget::setStyleSheet.
so, in you case you should write something like this

TabWindow::TabWindow(QWidget *parent) : QWidget(parent)
{
    QMenu  *menu=new QMenu(this);
    menu->setStyleSheet(...);
...
}

TabWindow::TabWindow(QWidget *parent) : QWidget(parent)
{
    QMenu  *menu=new QMenu(this);
    menu->setStyleSheet(...);
...
}

To copy to clipboard, switch view to plain text mode
