Custom button

[Erik-Moscow]

Hi!

There is a question to create button (or action for QToolBar) like this:

Here is two states: checked and unchecked + menu or other additional action.

Any ideas?
PS: sorry, if there exists topic like this...

Use QToolButton::setPopupMode(QToolButton::MenuButtonPopup) to get the menu drop down, and QAbstractButton::setCheckable(true) (inherited by QToolButton) to make the button checkable. Then supply both "On" and "Off" images for the QIcon you set on the button.

Yes, I created this: http://paste.org.ru/?nw5bfs But don't know how to create action instead menu
(really, it's needed to show widget insted menu)

(really, it's needed to show widget insted menu)

Perhaps it would work to create a QWidgetAction, then use QMenu::addAction(QAction*) to add it as the single item in a menu, then set that as the menu for the QToolButton.

Thanks a lot! Works great! =)
Working code:

#include <QApplication>
#include <QtGui>
 
int main(int argc, char **argv)
{
    QApplication app(argc, argv);
 
    QSlider *sl = new QSlider(Qt::Horizontal);
        sl->setRange(10, 100);
        sl->setFixedWidth(200);
        sl->setTickPosition(QSlider::TicksBelow);
 
    QWidgetAction *wa = new QWidgetAction(0);
        wa->setDefaultWidget(sl);
 
    QMenu *menu = new QMenu;
        menu->addAction(wa);
 
    QToolButton btn;
    btn.setText("Checkable");
    btn.setMenu(menu);
    btn.setPopupMode(QToolButton::MenuButtonPopup);
    btn.setCheckable(true);
 
    btn.show();
 
    return app.exec();
}

#include <QApplication>
#include <QtGui>

int main(int argc, char **argv)
{
    QApplication app(argc, argv);

    QSlider *sl = new QSlider(Qt::Horizontal);
        sl->setRange(10, 100);
        sl->setFixedWidth(200);
        sl->setTickPosition(QSlider::TicksBelow);

    QWidgetAction *wa = new QWidgetAction(0);
        wa->setDefaultWidget(sl);

    QMenu *menu = new QMenu;
        menu->addAction(wa);

    QToolButton btn;
    btn.setText("Checkable");
    btn.setMenu(menu);
    btn.setPopupMode(QToolButton::MenuButtonPopup);
    btn.setCheckable(true);
	
    btn.show();

    return app.exec();
}
