/* example of custom variable reference */
QWidget
{
    color: $text; /* reference variable text*/
    background-color: $background; /* reference variable background*/
}

When a variable is defined in QssStylesheetEditor, the variable will be automatically displayed in the color pannel. You can click the color button to select the variable color through the color pick-up box.

If an undefined variable is referenced, it will be automatically recognized and displayed in the color panel too.

Image reference path

When images are use in the qss code, if the url is relative, QssStylesheetEditor will find the image file in the folder where the qss code file is.

background-image: url("img/close.png");
/* the img folder must be in the same directory of the qss code file*/

image in resource file

If your image files is converted to resource file by pyrcc5(pyrcc5 xxx.qrc -o xxxresource.py).

You can reference images in the resource file as following:

background-image: url(":/img/close.png");

QssStylesheetEditor will search the resource file filename.py(filename must be same of qss file) in the directory of the currently opened qss stylesheet code file and loads it automatically.

QPalette reference

color: palette(Text);
background-color: palette(Window);

Changing color of QPalette is supported via pick-up color in palettdialog. And the new QPalette code can be viewed via click the "ViewPaletteCode" button.

The reset button in PaletteDialogreset could cancel QPalette modification.
