如何使用 PyQt5 设置窗口图标? [英] How to set a window icon with PyQt5?

问题描述

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

class Application(QMainWindow):
    def __init__(self):
        super(Application, self).__init__()
        self.setWindowIcon(QtGui.QIcon('icon.png'))

我正在尝试设置一个窗口图标(窗口左上角)，但正常图标却消失了.

I am trying to set a window icon (top left of the window) but the normal icon disappeared instead.

我尝试了许多图标分辨率(8x8、16x16、32x32、64x64)和扩展名(.png 和 .ico).

I tried with many icon resolutions (8x8, 16x16, 32x32, 64x64) and extensions (.png and .ico).

我做错了什么?

推荐答案

asker 建议的命令对我有用:

The command, as suggested by asker, works for me:

 self.setWindowIcon(QtGui.QIcon('icon.png'))

我放了 256x256 png，一切正常.我有 Win 7 pro 64 位，Python 3.5.2 32 位.

I put 256x256 png and all was OK. I have Win 7 pro 64 bit, Python 3.5.2 32 bit.
