如何将 CSS 样式类添加到 QWidget

Question

In JavaFx I can easily add a CSS style class as follows:

Scene scene = new Scene(new Group(), 500, 400);
scene.getStylesheets().add("path/stylesheet.css");

......

Label label = new Label("Cool Looking Styled Label");
label.getStyleClass().add("my-label-style");

css

.my-label-style {
    -fx-font: 16px "Serif";
    -fx-padding: 10;
    -fx-background-color: #CCFF99;
}

How can I go about adding a style class to a QWidget , QLabel , for example?

Answer 1

label->setProperty("class", "my-label-style");

Then in a CSS you can call it normally by:

.my-label-style {
  [..]
}

Answer 2

The method is in the QWidget base class; it's QWidget::setStyleSheet.

Answer 3

you have two ways to do that

coding

• widget.setStyleSheet("css code");

Form ui

• right click on the widget
• select change stylesheet
• a dialog box appears where you need to write css codes

but all css code are not supported,you need to see documentation of stylesheet
