Python获取系统上可用字体的列表

Question

如何获取系统中所有可用的字体（Linux）？

我搜索并找到了这个：http://www.lemoda.net/pango/list-fonts/ 但它是在 C 中并且依赖于 pango。

如何在 Python 中做到这一点？

Answer 1

您可以尝试在 ubuntu 上使用 fc-list，然后将每一行以 ":" 分割，以获取 ubuntu http://manpages.ubuntu.com/manpages/hardy/man1/fc-list.1.html 上的所有字体

map(lambda x : x.split(":")[1],commands.getstatusoutput('fc-list')[1].split("\n"))

虽然某些字体名称可能包含 python 可能无法正确打印的符号。

Answer 2

使用 PyQt5.QtGui.QFontDatabase 的 families 方法获取不同的可用字体

QFontDatabase().families()

下面是一个查看不同字体的gui程序

程序：

import sys
import textwrap

from PyQt5.QtWidgets import *
from PyQt5 import QtWidgets, QtGui, QtCore
from PyQt5.QtWidgets import QTextEdit
from PyQt5.QtGui import *
from PyQt5.QtCore import *


class Window(QWidget):

    def __init__(self):
        super().__init__()
        self.title = "Available fonts"
        self.width = 500
        self.height = 500
        self.top = 10
        self.left = 10
        self.initUI()
        self.show()

    def initUI(self):
        self.setGeometry(self.left, self.top, self.width, self.height)
        self.setWindowTitle(self.title)
        self.layout = QVBoxLayout()

        self.comboBox = QComboBox(self)
        self.families = QFontDatabase().families()
        print(type(self.families))
        self.comboBox.addItems(self.families)
        self.comboBox.setEditable(True)
        # Dont Add the new values to combobox
        self.comboBox.setInsertPolicy(QComboBox.NoInsert)
        # Autocompleting
        self.comboBox.completer().setCompletionMode(QtWidgets.QCompleter.PopupCompletion)
        song = ("""
            My Heart Will Go On\n
            by Celine Dion\n
            Every night in my dreams
            I see you, I feel you
            That is how I know you go on
            Far across the distance
            And spaces between us
            You have come to show you go on
            Near, far, wherever you are
            I believe that the heart does go on
            Once more, you open the door
            And you're here in my heart
            And my heart will go on and on
            Love can touch us one time
            And last for a lifetime
            And never let go 'til we're gone
            Love was when I loved you
            One true time I'd hold to
            In my life, we'll always go on
            Near, far, wherever you are
            I believe that the heart does go on
            Once more, you open the door
            And you're here in my heart
            And my heart will go on and on
            You're here, there's nothing I fear
            And I know that my heart will go on
            We'll stay forever this way
            You are safe in my heart and
            My heart will go on and """)
        # print(song)
        # when ever new item is selected from comboxbox call textChanged method
        self.comboBox.currentTextChanged.connect(self.textChanged)
        self.textEdit = QPlainTextEdit(song)
        self.layout.addWidget(self.comboBox)
        self.layout.addWidget(self.textEdit)
        # setting layout
        self.setLayout(self.layout)

    # Called when combo box current text is changed
    def textChanged(self):
        fontStr = self.comboBox.currentText()
        if fontStr in self.families:
            self.textEdit.setFont(QFont(fontStr))


if __name__ == "__main__":
    App = QApplication(sys.argv)
    window = Window()
    sys.exit(App.exec())

输出：
