    Default QPushButton - Only show the Icon

    Hi
    I checked the "flat" property on a QPushButton containing a Icon.
    Whe i press the button the original rectangular shape shows again?
    How do i disable this?

    Thanks

    I don't think this is possible, as the user needs some response that "something" is happening when he presses the flat button.
    Otherwise the button could be a QLabel which normally never changes its shape. But of course a label has no clicked() signal.

    I'm using 2 diferent Pixmaps for that.
    One for pressed and one for released.
    That's why i want the original sape to go away.

    Then subclass QPushButton and write your own print() method. It's not that difficult.

    Qt source code . There are billions of paint methods implemented. Start at QPushButton:: paint().

    Ah, I'm going crazy. I cant keep that in mind! It's not print and neither it's paint: It's QWidget::paintEvent(QPaintEvent *event)!

    Qt Code:
    1. class MyButton : public QPushButton
    2. {
    3. //...
    4. void setImages(QImage normal, QImage pressed /*...*/);
    5. protected:
    6. void paintEvent(QPaintEvent *event);
    7. private:
    8. QImage m_normal;//...
    9. };
    10.  
    11. void MyButton::paintEvent(QPaintEvent *event)
    12. {
    13. QPainter painter(this);
    14. // do your painting here
    15. }
    To copy to clipboard, switch view to plain text mode

    It should be possible to obtain the same effect purely by using stylesheets too.
    Your biological and technological distinctiveness will be added to our own. Resistance is futile.

    Please ask Qt related questions on the forum and not using private messages or visitor messages.

    Yess ... that's what i did for not making the solution "too complex" for the moment.
    this did the job:
    Qt Code:
    1. w.setStyleSheet("QPushButton {border-style: outset; border-width: 0px;}");
    To copy to clipboard, switch view to plain text mode 

    Thanks all
