Style Sheet Editor

Qt Style Sheets allow the user to customize the appearance of widgets. Qt Style Sheets are similar to HTML Cascading Style Sheets (CSS) but adapted to widgets. To define style sheets, open the Editor with Display => Customize style sheet.

The following example customizes the appearance of the three tree views. The tree items are drawn in black, selected tree items in red. The background color of the tree items is set to lightgray, the background color of selected items to green. To draw the tree items, the font family "Bitstream Charter" with 10 point size is used.

QTreeView {
      color: black;
      background-color: lightgray; 
      selection-color:red;
      selection-background-color:lightgreen;
      font-family: Bitstream Charter;
      font-size: 10pt
    }
