如何使用 PyQt 根据屏幕分辨率调整主窗口的大小 [英] How can I resize the main window depending on screen resolution using PyQt

问题描述

我有一个包含三个框架的主窗口.顶部框架由页眉组成，底部框架由页脚组成.我使用 PyQt4 设计器设计它.当我在我的笔记本电脑上运行它时窗口看起来很好，屏幕分辨率为 1920*1080.但是当我在 1600*900 等其他分辨率上检查相同的内容时，页脚被切断了.我想知道是否有办法在运行时根据屏幕分辨率调整窗口大小，以便显示所有三个帧.我试图在线检查是否有任何解决方案，但找不到任何解决方案.我尝试使用 window.setGeometry 和 window.setFixedSize 函数，但没有用.

I have a main window with three frames.The top frame consists of the header and the bottom frame consists of the footer. I designed it using the PyQt4 designer.The window looks fine when I run it on my laptop with a screen resolution of 1920*1080. But when I check the same on other resolutions like 1600*900 the footer gets cut off. I wanted to know if there is a way to resize the window according to screen resolution in the runtime so that all the three frames are shown. I tried to check online if there are any solutions for this but could not find any. I tried using window.setGeometry and window.setFixedSize functions,but it did not work.

窗口代码为:

import sys
import os
import threading
import smtplib

from PyQt4 import QtCore, QtGui, uic
import sched
import time

form_class = uic.loadUiType("FirstTest.ui")[0]                 # Load the UI
try:
    _fromUtf8 = QtCore.QString.fromUtf8
except AttributeError:
    _fromUtf8 = lambda s: s

class MyWindowClass(QtGui.QMainWindow, form_class):
    def __init__(self, parent=None):
        QtGui.QMainWindow.__init__(self, parent)        
        self.setupUi(self)        

#has some code for the field values to be shown







app = QtGui.QApplication(sys.argv)
myWindow = MyWindowClass(None)
#myWindow.setFixedSize(500,500)
myWindow.showMaximized()
palette = QtGui.QPalette()
palette.setColor(QtGui.QPalette.Background,QtCore.Qt.white)
myWindow.setPalette(palette)
myWindow.show()
app.exec_()

推荐答案

您可以使用

showFullScreen() 或只是 showMaximized()

您可以通过以下方式获取屏幕几何图形:

and you can get screen geometry with:

desktop() 和 screenGeometry()
