工作中,工具用到了python Qt5,涉及到了按钮颜色,这里就做个总结。也顺便给要用这块的同仁抛出来一个砖头,把大牛引出来做个指导。
一般设置按钮的颜色有三种表达:如下所示:具体的怎么使用,估计要看一下用例就清楚了。
QPushButton button1, button2, button3; button1.setStyleSheet("background-color: red"); button2.setStyleSheet("background-color:#ff0000;"); button3.setStyleSheet("background-color:rgb(255,0,0)");
接下来上一个例子:
1 import sys 2 from PyQt5.QtWidgets import QApplication, QWidget, QPushButton 3 from PyQt5.QtGui import QIcon 4 from PyQt5.QtCore import pyqtSlot 5 global ival 6 class App(QWidget): 7 8 def __init__(self): 9 super().__init__() 10 self.title = 'PyQt5 button color:https://www.cnblogs.com/dylancao/' 11 self.left = 10 12 self.top = 10 13 self.width = 320 14 self.height = 200 15 self.initUI() 16 global ival 17 ival = 0 18 19 def initUI(self): 20 self.setWindowTitle(self.title) 21 self.setGeometry(self.left, self.top, self.width, self.height) 22 23 self.button = QPushButton('Color', self) 24 self.button.setToolTip('This is an example button about color ') 25 self.button.setStyleSheet("background-color: red") 26 self.button.move(100,70) 27 self.button.clicked.connect(self.on_click) 28 29 self.show() 30 31 @pyqtSlot() 32 def on_click(self): 33 global ival 34 ival += 1 35 if ival == 1: 36 self.button.setStyleSheet("background-color: red") 37 elif ival == 2: 38 self.button.setStyleSheet("background-color: #ffff00;") 39 elif ival == 3: 40 ival = 0 41 self.button.setStyleSheet("background-color: rgb(0,255,255)") 42 43 print('PyQt5 button click:',ival) 44 45 if __name__ == '__main__': 46 app = QApplication(sys.argv) 47 ex = App() 48 sys.exit(app.exec_())
运行的结果:
