MainWindow::MainWindow(QWidget *parent) : QMainWindow(parent), ui(new Ui::MainWindow) { ui->setupUi(this); // setWindowFlags(Qt::FramelessWindowHint); //color 设定前景色，就是字体的颜色 //background 设定后景色，就是按钮的背景的颜色 ui->pushButton->setStyleSheet("QPushButton{color:red;background:yellow}"); //background跟background-color:rgb(r,g,b)效果一样，只不过是使用rgb来设定背景颜色 ui->pushButton_2->setStyleSheet("QPushButton{color:blue;" "background-color:rgb(255,0,0)}"); ui->pushButton_3->resize(100,100); ui->pushButton_3->setStyleSheet("QPushButton{" "background-image:url(:image/07_u.png);"//设置按钮背景图片 "background-repeat:repeat-xy;" //设置按钮的背景图片的重复规则，x方向y方向，xy方向 "background-position:Center;" //设定背景图片在按钮中的位置,按左对齐Left，右Right，中间Center，上Top，底部Bottom "background-attachment:fixed;" "background-clip:padding}"); //可以使用border-top,border-right,border-bottom,border-left分别设定按钮上下左右边框 //border-image设定边框的北京图片 //border-radius设定边框的弧度 ui->pushButton_4->setStyleSheet("QPushButton{" "border:3px solid white;" //宽度为3px的红色边框 "border-radius:5px}"); //边框角的弧度为8px ui->pushButton_5->resize(70,70); ui->pushButton_5->setStyleSheet("QPushButton{" "min-height:20;" "border-style:solid;" "border-top-left-radius:2px;" "border-top-right-radius:2px;" "background: qlineargradient(x1: 0, y1: 0, x2: 0, y2: 1, stop:0 rgb(226,236,241), " "stop: 0.2 rgb(233,242,247)," "stop: 0.7 rgb(176,208,225)," "stop: 0.8 rgb(176,208,225)," "stop: 1 rgb(192,216,232));" "}"); //border:3px solid red; setStyleSheet("QWidget{background-color:rgb(255,255,255);" "}"); }
