Change QCheckBox Style in Qt Jambi

I am currently using Eclipse 3.5.2 and Qt Jambi 4.7.2 in Ubuntu 11.04 Natty Narwhal

I am trying to use stylesheets to customize my QCheckBox. I have found examples for C++ but I cannot find equivalents for Java. I am wanting to do so开发者_运维知识库mething similar to the following using stylesheets.

QCheckBox::indicator {
    width: 13px;
    height: 13px;
}

QCheckBox::indicator:unchecked {
    image: url(:/images/checkbox_unchecked.png);
}

QCheckBox::indicator:unchecked:hover {
    image: url(:/images/checkbox_unchecked_hover.png);
}

QCheckBox::indicator:unchecked:pressed {
    image: url(:/images/checkbox_unchecked_pressed.png);
}

QCheckBox::indicator:checked {
    image: url(:/images/checkbox_checked.png);
}

QCheckBox::indicator:checked:hover {
    image: url(:/images/checkbox_checked_hover.png);
}

QCheckBox::indicator:checked:pressed {
    image: url(:/images/checkbox_checked_pressed.png);
}

If anyone could help me out, it would be much appreciated. Thanks in advance!

Also, does anyone know how to make a QCheckBox bigger?

Judging this page, you can set stylesheets into use with QApplication::setStyleSheet() and QWidget::setStyleSheet(). Neither of those is static function, so something like

MyWidget widget = new MyWidget();
widget.setStyleSheet("path/to/stylesheet");

Note that I haven’t myself tried those stylesheets, as a developer of Jambi I’d be interested if those styleheets actually work and if they could be fixed then.

EDIT: And for making check boxes bigger, maybe easiest way is to wrap them into layouts and let layouts to populate whole widget size -> with one item in a layout the widget in layout would be as big as the widget where the layout is attached to.

In order to change the size of the check box you can use

QCheckBox::indicator {
    width: 50px;
    height: 50px;
}

in your style sheet. This makes the check mark very pixelated however so I then proceeded to use

QCheckkBox::indicator:checked {
   border-image: url(classpath:Icons/checkmark.png);
}

along with the first thing. It works wonderfully and the checkmark can be any image you want to use!
