如何在Qt应用程序中使用样式表更改QPushButton图标

Question

Is it possible to set and change the icon on a QPushButton using stylesheets?

I need this for a Windows-based white-label Qt4.5 application that customers stylize using stylesheets.

Thanks.

Answer 1

A little late for a reply, but in case anyone else pops on this via google;

You can add the icon by changing the QAbstractButton-property. Simply use:

QAbstractButton {
     qproperty-icon: theme_url("/button_action/add");
}

The type-selector (QAbstractButton), enables you to set the style for the selected object and all its subclasses . Since QProcessButton extends the QAbstractButton, this will do the trick. (Of course you could also use the QPushButton type-selector here).

For more information on how to use selectors, I found this quite helpful.

If you want to learn more about the button-properties, refer to the QT-Documentation here .

PS. In case you want to change the icon, once the button is clicked, use

qproperty-icon: url(":/Icons/before_click.png") off,
                url(":/Icons/after_click.png") on ;

对。

border-image: url(/url/to/image);

Answer 3

You can use:

image: url(/url/to/image);
