高分辨率屏幕上的 PyQt GUI 大小 [英] PyQt GUI size on high resolution screens
本文介绍了高分辨率屏幕上的 PyQt GUI 大小的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我不久前发布了一个
解决方案
在应用加载前,而不是在加载时.
插入:
if hasattr(QtCore.Qt, 'AA_EnableHighDpiScaling'):PyQt5.QtWidgets.QApplication.setAttribute(QtCore.Qt.AA_EnableHighDpiScaling, True)如果 hasattr(QtCore.Qt, 'AA_UseHighDpiPixmaps'):PyQt5.QtWidgets.QApplication.setAttribute(QtCore.Qt.AA_UseHighDpiPixmaps, True)
像这样:
导入 PyQt5从 PyQt5 导入 QtCore、QtGui、uic、QtWidgets从 PyQt5.QtWidgets 导入 QWidget如果 hasattr(QtCore.Qt, 'AA_EnableHighDpiScaling'):PyQt5.QtWidgets.QApplication.setAttribute(QtCore.Qt.AA_EnableHighDpiScaling, True)如果 hasattr(QtCore.Qt, 'AA_UseHighDpiPixmaps'):PyQt5.QtWidgets.QApplication.setAttribute(QtCore.Qt.AA_UseHighDpiPixmaps, True)类 MyWindow(PyQt5.QtWidgets.QMainWindow):def __init__(self):super(MyWindow, self).__init__()
如果这仍然不起作用,请在 user en var 中,而不是在 system en var 中.
QT_AUTO_SCREEN_SCALE_FACTOR=2
I posted a question a while ago asking about Tkinter backends and subsequently forgot about it but I've since realised that I'm using the pyqt backend. Is there a fix for that?
Original Question:
So it appears that matplotlib gui plots (a la plt.show()) don't adapt to monitor resolution and appear tiny on high resolution screens. Is there a matplotlib+Pyqt fix or do I have fiddle around somewhere in Windows settings?
Thanks
解决方案
Before app is loaded, and not while loading.
insert:
if hasattr(QtCore.Qt, 'AA_EnableHighDpiScaling'):
PyQt5.QtWidgets.QApplication.setAttribute(QtCore.Qt.AA_EnableHighDpiScaling, True)
if hasattr(QtCore.Qt, 'AA_UseHighDpiPixmaps'):
PyQt5.QtWidgets.QApplication.setAttribute(QtCore.Qt.AA_UseHighDpiPixmaps, True)
like so :
import PyQt5
from PyQt5 import QtCore, QtGui, uic, QtWidgets
from PyQt5.QtWidgets import QWidget
if hasattr(QtCore.Qt, 'AA_EnableHighDpiScaling'):
PyQt5.QtWidgets.QApplication.setAttribute(QtCore.Qt.AA_EnableHighDpiScaling, True)
if hasattr(QtCore.Qt, 'AA_UseHighDpiPixmaps'):
PyQt5.QtWidgets.QApplication.setAttribute(QtCore.Qt.AA_UseHighDpiPixmaps, True)
class MyWindow(PyQt5.QtWidgets.QMainWindow):
def __init__(self):
super(MyWindow, self).__init__()
And if that still don't work, in user en var and not system en var.
