pyqt5-字体，颜色选择对话框设置label标签字体颜色样式

1.采用实例方法，先创建2个dialog对象，采用该对象的信号触发相应的操作

import sys

from PyQt5.Qt import *

class MyWidget(QWidget):

    def __init__(self):

        QWidget.__init__(self)

        self.resize(500,500)

        self.setup_ui()

    def setup_ui(self):

        self.btn = QPushButton("选择字体",self)

        self.color_btn = QPushButton("选择颜色",self)

        self.color_btn.move(100,0)

        self.fd = QFontDialog(self)

        self.qfc = QColorDialog(self)

        self.fd.fontSelected.connect(self.font_select)

        self.fd.currentFontChanged.connect(self.font_select)

        self.qfc.colorSelected.connect(self.color_select)

        self.label = QLabel("天佑中华！",self)

        self.label.move(100,100)

        self.btn.clicked.connect(self.open_choose)

        self.color_btn.clicked.connect(self.open_color_choose)

    def color_select(self,color):

        red,green,blue,_ = color.getRgb()

        self.label.setStyleSheet("color:rgb({},{},{},255)".format(red,green,blue))

    def open_color_choose(self):

        self.qfc.open()

    def open_choose(self):

        self.fd.open()

    def font_select(self,font):

        self.label.setFont(font)

        self.label.adjustSize()

if __name__ == "__main__":

    app = QApplication([])

    window = MyWidget()

    window.show()

    sys.exit(app.exec_())

2.采用类静态方法，直接获取返回值

import sys

from PyQt5.Qt import *

class MyWidget(QWidget):

    def __init__(self):

        QWidget.__init__(self)

        self.resize(500,500)

        self.setup_ui()

    def setup_ui(self):

        self.btn = QPushButton("选择字体",self)

        self.color_btn = QPushButton("选择颜色",self)

        self.label = QLabel("天佑中华！", self)

        self.color_btn.move(100,0)

        self.label.move(100,100)

        self.btn.clicked.connect(self.open_choose)

        self.color_btn.clicked.connect(self.open_color_choose)

    def open_color_choose(self):

        qcolor = QColorDialog.getColor()

        red, green, blue, _ = qcolor.getRgb()

        self.label.setStyleSheet("color:rgb({},{},{},255)".format(red, green, blue))

    def open_choose(self):

        font,ischecked = QFontDialog.getFont(self)

        if ischecked:

            self.label.setFont(font)

            self.label.adjustSize()

if __name__ == "__main__":

    app = QApplication([])

    window = MyWidget()

    window.show()

    sys.exit(app.exec_())
