本節主要介紹PyQt的調色板的使用,在點擊按鈕後對窗體進行着色,具體代碼以下python
import sys from PyQt5 import QtGui from PyQt5.QtWidgets import QApplication, QWidget, QPushButton, QColorDialog from PyQt5.QtGui import QPainter from PyQt5.QtCore import pyqtSlot class App(QWidget): def __init__(self): super().__init__() self.title = 'PyQt5 color dialog - pythonspot.com' self.left = 100 self.top = 100 self.width = 320 self.height = 200 self.initUI() def initUI(self): self.setWindowTitle(self.title) self.setGeometry(self.left, self.top, self.width, self.height) button = QPushButton('Open color dialog', self) button.setToolTip('Opens color dialog') button.move(10, 10) button.clicked.connect(self.on_click) self.show() @pyqtSlot() def on_click(self): qp = QPainter(self) color = QColorDialog.getColor() if color.isValid(): # 實例化調色板 palette1 = QtGui.QPalette() # 設置調色板顏色 palette1.setColor(palette1.Background, color) # 應用調色板 self.setPalette(palette1) print(color.name()) if __name__ == '__main__': app = QApplication(sys.argv) ex = App() sys.exit(app.exec_())
