PyQt5 QColorDialog – 获取字体
在本文中,我们将了解如何获取 QColorDialog 的字体。字体是颜色对话框中文本的样式,即属性。我们使用setFont
方法来设置对话框的字体。
注意:增加字体大小会增加对话框的大小,尽管对话框大小是固定的
为了做到这一点,我们使用带有 QColorDialog 对象的font
方法
Syntax : dialog.font()
Argument : It takes no argument
Return : It returns QFont object
下面是实现
# importing libraries
from PyQt5.QtWidgets import *
from PyQt5 import QtCore, QtGui
from PyQt5.QtGui import *
from PyQt5.QtCore import *
import sys
class Window(QMainWindow):
def __init__(self):
super().__init__()
# setting title
self.setWindowTitle("Python ")
# setting geometry
self.setGeometry(100, 100, 500, 400)
# calling method
self.UiComponents()
# showing all the widgets
self.show()
# method for components
def UiComponents(self):
# creating a QColorDialog object
dialog = QColorDialog(self)
# setting custom colors
dialog.setCustomColor(1, Qt.red)
dialog.setCustomColor(2, Qt.green)
dialog.setCustomColor(3, Qt.yellow)
dialog.setCustomColor(4, Qt.blue)
# font
font = QFont('Times', 12)
# setting font to the dialog
dialog.setFont(font)
# creating label
label = QLabel("Geeks for Geeks", self)
label.setAlignment(Qt.AlignCenter)
# making label multi line
label.setWordWrap(True)
# setting stylesheet of the label
label.setStyleSheet("QLabel"
"{"
"border : 5px solid black;"
"}")
# getting the custom color
color = dialog.customColor(4)
# setting graphic effect to the label
graphic = QGraphicsColorizeEffect(self)
# setting color to the graphic
graphic.setColor(color)
# setting graphic to the label
label.setGraphicsEffect(graphic)
layout = dialog.layout()
layout.addWidget(label)
dialog.setLayout(layout)
# getting font
value = dialog.font()
# setting text to the label
label.setText("Font : " + str(value))
dialog.exec_()
self.deleteLater()
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
输出 :
