问题描述

我在Windows 8.1
64位上使用PyQt5 5.5.1(64位)和Python 3.4.0(64位)。

I am using PyQt5 5.5.1 (64-bit) with Python 3.4.0 (64-bit) on Windows 8.1 64-bit.

我在恢复非常简单的PyQt应用程序
的位置和大小(几何形状)时遇到麻烦。

I am having trouble restoring the position and size (geometry) of my very simple PyQt app.

这是最小的工作应用程序:

Here is minimal working application:

import sys
from PyQt5.QtWidgets import QApplication, QWidget

class myApp(QWidget):
    def __init__(self):
        super().__init__()
        self.initUI()


    def initUI(self):
        self.show()

if __name__ == '__main__':
    app = QApplication(sys.argv)
    view = myApp()
    sys.exit(app.exec())






我在网上阅读的是这是默认行为,我们需要
使用QSettings保存和检索Windows注册表中的设置,
存储在


What I read online is that this is the default behavior and we need to use QSettings to save and retrieve settings from Windows registry, which is stored in

\\HKEY_CURRENT_USER\Software\{CompanyName}\{AppName}\

此处 一些 链接 我读了

遵循了这些教程,但是那些教程/文档是为C ++用户编写的

I could have followed those tutorials but those tutorials/docs were written for C++ users.

C ++不是我的杯水,转换这些代码对我来说是不可能的。

C++ is not my glass of beer, and converting those codes are impossible to me.

QSettings():如何保存到当前工作目录

推荐答案

应该这样做。

import sys
from PyQt5.QtWidgets import QApplication, QWidget
from PyQt5.QtCore import QSettings, QPoint, QSize

class myApp(QWidget):
    def __init__(self):
        super(myApp, self).__init__()

        self.settings = QSettings( 'My company', 'myApp')     

        # Initial window size/pos last saved. Use default values for first time
        self.resize(self.settings.value("size", QSize(270, 225)))
        self.move(self.settings.value("pos", QPoint(50, 50)))

    def closeEvent(self, e):
        # Write window size and position to config file
        self.settings.setValue("size", self.size())
        self.settings.setValue("pos", self.pos())

        e.accept()

if __name__ == '__main__':
    app = QApplication(sys.argv)
    frame = myApp()
    frame.show()
    app.exec_()

我简化了此示例: QSettings():如何保存到当前工作目录
