QToolButton bottom left down arrow



  • Hey folks,

    i want to create a QToolButton with instant popup and down arrow alongside button text. It is working for me by setting the ToolButtonStyle and DownArrow. The image below shows the tool button.

    Image 1

    However, when i add an Action to the tool button, another down arrow in the lower right corner appears like presented by the image below.

    alt text

    I do not want that arrow. Is there any way to get rid of the down arrow in the lower right corner?

    Minimal example

    main.cpp

    #include "mainwindow.h"
    #include <QApplication>
    
    int main(int argc, char *argv[])
    {
        QApplication a(argc, argv);
        MainWindow w;
        w.show();
    
        return a.exec();
    }
    

    mainwindow.h

    #ifndef MAINWINDOW_H
    #define MAINWINDOW_H
    
    #include <QMainWindow>
    
    namespace Ui {
    class MainWindow;
    }
    
    class MainWindow : public QMainWindow
    {
        Q_OBJECT
    
    public:
        explicit MainWindow(QWidget *parent = 0);
        ~MainWindow();
    
    private:
        Ui::MainWindow *ui;
        QAction* myDummyAction;
        QMenu* myMenu;
    };
    
    #endif // MAINWINDOW_H
    

    mainwindow.cpp

    #include"mainwindow.h"
    #include"ui_mainwindow.h"
    
    #include<QAction>
    
    MainWindow::MainWindow(QWidget *parent) :
        QMainWindow(parent),
        ui(new Ui::MainWindow)
    {
        myDummyAction = new QAction("dummy action", this);
    
        ui->setupUi(this);
    
        ui->toolButton->addAction(myDummyAction);
    }
    
    MainWindow::~MainWindow()
    {
        delete ui;
    }

  • Hi @DaStroe

    What about using setDefaultAction instead of addAction ?

    Your cpp will look to something like this:

    #include "mainwindow.h"
    #include "ui_mainwindow.h"
    
    #include <QDebug>
    MainWindow::MainWindow(QWidget *parent) :
        QMainWindow(parent),
        ui(new Ui::MainWindow)
    {
        ui->setupUi(this);
        myDummyAction = new QAction("dummy action", this);
    
        ui->toolButton->setDefaultAction(myDummyAction);//use setDefaultAction instead of addAction
    }
    
    MainWindow::~MainWindow()
    {
        delete ui;
    }
    


  • Hi mostefa

    Using setDefaultAction removes the arrow in the lower right. However, i want to create a drop down menu with multiple actions, which pops up on click. The setDefaultAction method does not create such a menu.

    Is there any way to have a drop down menu in QToolButton without having the down arrow in the lower right corner?

    Regards

  • I think it should work with:

    QToolButton::down-arrow {
    image: none;
    background-color: red;
    }

    in your stylesheet
