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_()
