The Style Sheet example shows how widgets can be styled using Qt Style Sheets. You can open the style editor by selecting File > Edit Style Sheet, to select an existing style sheet or design your own style and load it.

The Style Sheet example consists of 2 classes:

• MainWindow
• StyleSheetEditor

MainWindow Class

MainWindow inherits QWidget, and is the application's main window defined in mainwindow.ui. The style of MainWindow can be modified with StyleSheetEditor.

StyleSheetEditor Class

StyleSheetEditor enables you to open an editor where you can load an existing style sheet. It is also possible to define a new stylesheet and load it. Its layout is defined in stylesheeteditor.ui.

void StyleSheetEditor::on_styleCombo_activated(const QString &styleName)

void StyleSheetEditor::on_styleSheetCombo_activated(const QString &sheetName)
