Qt-custom attributes for style sheets

achieve

     1, ui defines the style sheet

// 在最开始的类中右键 - 样式表
QPushButton#button2[test="true"]{
    
    color:green;}
QPushButton#button2[test="false"]{
    
    color:red;}

 

     2. Define attributes and implementation in the main class

#define POLISH(widget) (widget->style()->polish(widget))

class Widget : pulib QWidget
{
    
    
    Q_OBJECT

    Q_PROPERTY(bool test READ getTest WRITE setTest)

public:
    Widget(QWidget *parent = nullptr) : QWidget(parent){
    
    }
    
protected:
    bool getTest(){
    
    return test;}
    void setTest(const bool &b){
    
    test = b;}
    
protected slots:
	// button1点击测试 - button2显示样式
	void on_button1_clicked();					
	{
    
    
		static bool b = false;
		b = !b;
		
		ui.button2->setProperty("test",b);

		// 设置完属性想要button2更改样式就必须进行刷新
		// 方案1:
		ui.button2->style()->polish(ui.button2)
		// 方案2 (注意传入为指针,该指针不能为空)
		// POLISH(ui.button2);
	}
	
private:
    bool test = false;
}

 

Mention

     It seems that you don't need to set Q_PROPERTY. Just set the attribute value for the corresponding control, wow.

 

reference

     Can refer to Qt properties
