pyqt5之QColorDialog颜色对话框最简单使用

QWidget.setStyleSheet(‘QWidget {background-color:#88ab45}‘) 

col=QColorDialog.getColor()
col.name() 此值就是颜色值的十六进制

from PyQt5.QtWidgets import QApplication,QWidget,QColorDialog
import sys
from t import Ui_Form

class myform(QWidget,Ui_Form):
    def __init__(self):
        super().__init__()
        self.setupUi(self)
        self.btn.clicked.connect(self.ok)
    def ok(self):        
        col=QColorDialog.getColor()
        self.setStyleSheet(‘QWidget {background-color:%s}‘ %col.name()) 
        
if __name__==‘__main__‘:
    app=QApplication(sys.argv)
    w=myform()
    w.show()
    app.exec_()
