下面寫個很簡單可以改變按鈕外觀的方法

 

到designer裡按右鍵,變更樣式表即可

 

 

 

Another way, to edit it's StyleSheets. It's easy!

 

 

 

#include <QApplication>
#include <QPushButton>
#include <QFont>
#include <QMenu>
#include <QLabel>
 
int main(int argc, char *argv[]) {
 
 
     QApplication app(argc, argv);
 
     QPushButton *btn = new QPushButton("Close");
     btn->setWindowTitle("Signal & Slot");
     btn->setFont(QFont("Courier", 18, QFont::Bold));
     btn->resize(250, 50);
     btn->setStyleSheet("background-color: yellow");
 
     QObject::connect(btn, SIGNAL(clicked()), &app, SLOT(quit()));
 
     btn->show();
 
 
     return app.exec();
}
