get property from qss in runtime

[steep8]

I have qss file like this :

QSlider::groove:horizontal {
 
     border: 1px solid #999999;
 
     height: 10px; 
 
     background: #c4c4c4;
 
     margin: 0px 5px 0 5px;
 
 }

QSlider::groove:horizontal {

     border: 1px solid #999999;

     height: 10px; 

     background: #c4c4c4;

     margin: 0px 5px 0 5px;

 }

How to get margin property at runtime?, like

int margin_right = getMarginRight();

int margin_right = getMarginRight();

To copy to clipboard, switch view to plain text mode 

Its useful to paint custom rectangle like:

const QRect slider_rect_groove = style()->subControlRect(QStyle::CC_Slider, &opt, QStyle::SC_SliderGroove , this);
 
int rect_position_x = slider_rect.right();
 
int current_width = rect_width * (slider_rect_groove.width() - margin_right)/100 - rect_position_x;

const QRect slider_rect_groove = style()->subControlRect(QStyle::CC_Slider, &opt, QStyle::SC_SliderGroove , this);

int rect_position_x = slider_rect.right();

int current_width = rect_width * (slider_rect_groove.width() - margin_right)/100 - rect_position_x;

Style sheets are a custom engine that bypasses C++. There is no way to query for a particular property of qss. If you want such information available, code it in C++.
