This example shows you how to apply a style sheet application-wide.


Applying a Qt style sheet to an application via QApplication

#include "yourwindow.h"
#include <QtGui>
#include <QApplication>
#include <QFile>
#include <QString>
#include <QTextStream>
void loadStyleSheet() {
/* Let's use QFile and point to a resource... */
QFile data(":/style.qss");
QString style;
/* open the file */
if( {
/* QTextStream... */
QTextStream styleIn(&data);
/* file to a string. */
style = styleIn.readAll();
/* We'll use qApp macro to get the QApplication pointer
* and set the style sheet application wide. */

int main(int argc, char *argv[]) {
QApplication a(argc, argv);
YourWindow* w = new YourWindow();
/* Load style sheet */
int returnValue = a.exec();
return returnValue;


Now you can style your application with Qt style sheets.
