Load global stylesheet from resource.qrc and apply it to the application?

Shadowblitz16

can someone tell me how to load a global stylesheet from my resources and apply it to my application?

this is my mainwindow.cpp

#include "mainwindow.h"
#include "ui_mainwindow.h"

#include <QFontDatabase>
#include <QFileDialog>

MainWindow::MainWindow(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::MainWindow)
{
    ui->setupUi(this);
    ui->statusBar->setSizeGripEnabled(false);
    setStyleSheet("Styles/Style.qss");
}

MainWindow::~MainWindow()
{
    delete ui;
}

and this is my style.qss file


QToolBar {
	border-image: url(Images/Panel1_Normal);
	border-top: 4;
	border-left: 4;
	border-bottom: 4;
	border-right: 4;
}

I feel it might have something to do with me passing the file in directly and not getting the contents as a string, however I'm not sure how to do this.

EDIT: ok so I tried to do this

#include "mainwindow.h"
#include "ui_mainwindow.h"

#include <QFontDatabase>
#include <QFileDialog>
#include <QTextStream>

MainWindow::MainWindow(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::MainWindow)
{
    ui->setupUi(this);
    ui->statusBar->setSizeGripEnabled(false);

    QFile file("Styles/Style.qss");
    if (!file.open(QIODevice::ReadOnly | QIODevice::Text)) return;
    QTextStream in(&file);
    QString text;
    text = in.readAll();
    file.close();

    setStyleSheet(text);
}

MainWindow::~MainWindow()
{
    delete ui;
}

to convert the style sheet into a string but my application toolbar still doesn't change

EDIT2: ok so I figured it out I just did this in my main.cpp

#include "mainwindow.h"
#include <QApplication>

#include <QFile>

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    MainWindow w;

    // Load an application style
    QFile styleFile( ":/Styles/Resources/Styles/Style.qss");
    styleFile.open( QFile::ReadOnly );

    // Apply the loaded stylesheet
    QString style( styleFile.readAll() );
    a.setStyleSheet( style );

    w.show();

    return a.exec();
}
