PyQT5 顏色對話方塊
PyQt5 支援一種名為 QColorDialog 的顏色選擇器。此對話方塊是你在繪畫或圖形程式中看到的典型對話方塊。
要從 PyQt5 對話方塊中獲取顏色,只需呼叫:
color = QColorDialog.getColor()

PyQt5 顏色對話方塊示例
下面的示例在單擊按鈕後開啟 QColorDialog,並返回所選顏色。
import sys
from PyQt5.QtWidgets import QApplication, QWidget, QPushButton, QColorDialog
from PyQt5.QtGui import QIcon
from PyQt5.QtCore import pyqtSlot
from PyQt5.QtGui import QColor
class App(QWidget):
def __init__(self):
super().__init__()
self.title = 'PyQt5 color dialog - tastones.com'
self.left = 10
self.top = 10
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):
openColorDialog(self)
def openColorDialog(self):
color = QColorDialog.getColor()
if color.isValid():
print(color.name())
if __name__ == '__main__':
app = QApplication(sys.argv)
ex = App()
sys.exit(app.exec_())
