from PyQt4.QtGui import *

from PyQt4.QtCore import *

import sys

import qtawesome as qta

class MyWindow(QMainWindow):

def __init__(self):

super(MyWindow, self).__init__()

mainWidget = QWidget()

layout = QVBoxLayout(mainWidget)

icon1 = qta.icon('fa.music', scale_factor = 1, color='blue')

btn1 = QPushButton(icon1, 'Icon + Text')

font=QFont(btn1.font())

font.setPointSize(30)

btn1.setFont(font)

btn2 = QPushButton(unichr(0xf101))

btn2.setFont(qta.font('fa', 50))

layout.addWidget(btn1)

layout.addWidget(btn2)

self.setCentralWidget(mainWidget)

btn1.clicked.connect(quit)

def main():

app = QApplication(sys.argv)

mainWnd = MyWindow()

mainWnd.show()

sys.exit(app.exec_())

if __name__ == '__main__':

main()

2、不使用第三方库文件，要求在当前目录下必需有字体文件：fontawesome-webfont.ttf

import sys

from PyQt4.QtGui import *

from PyQt4.QtCore import *

class MyWindow(QMainWindow):

css = """

QToolButton{{

border: None;

"""

def __init__(self):

super(MyWindow, self).__init__()

self.setStyleSheet(self.css.format())

fontId = QFontDatabase.addApplicationFont("fontawesome-webfont.ttf")

fontName = QFontDatabase.applicationFontFamilies(fontId)[0]

self.font = QFont(fontName, 30)

btn = QToolButton(self)

btn.setToolButtonStyle(Qt.ToolButtonIconOnly)

btn.setFont(self.font)

btn.setText(unichr(0xf101))

self.setCentralWidget(btn)

btn.clicked.connect(quit)

def main():
