如何将 Qt Designer 中的表单另存为独立应用程序? [英] How to save a form from Qt Designer as a standalone app?

问题描述

我在 Qt Designer 中创建了一个表单模型，现在我想将表单保存为(exe?)文件，以便它可以在计算机上运行.

I have created a mock-up of a form in Qt Designer, and now I would like to save the form as a (exe?) file so that it can be run on the computer.

我会使用Python to Exe"吗(如果是，如何使用)?我对编程还不太了解.

Would I use 'Python to Exe' (if so, how)? I don't know much about programming yet.

Qt Designer 使用 .ui 扩展名保存文件.

Qt Designer saves the files with a .ui extension.

推荐答案

要使用 PyInstaller 创建独立应用程序，请按照下列步骤操作:

To create a standalone app with PyInstaller follow these steps:

1. 将此代码保存为您的 MyWidget.ui 文件:

<?xml version="1.0" encoding="UTF-8"?>
<ui version="4.0">
 <class>MainWindow</class>
 <widget class="QMainWindow" name="MainWindow">
  <property name="geometry">
   <rect>
    <x>0</x>
    <y>0</y>
    <width>147</width>
    <height>125</height>
   </rect>
  </property>
  <property name="windowTitle">
   <string>MainWindow</string>
  </property>
  <widget class="QWidget" name="centralwidget">
   <layout class="QVBoxLayout" name="verticalLayout">
    <item>
     <widget class="QLineEdit" name="lineEdit"/>
    </item>
    <item>
     <widget class="QPushButton" name="pushButton">
      <property name="text">
       <string>Click Me</string>
      </property>
     </widget>
    </item>
   </layout>
  </widget>
  <widget class="QMenuBar" name="menubar">
   <property name="geometry">
    <rect>
     <x>0</x>
     <y>0</y>
     <width>147</width>
     <height>25</height>
    </rect>
   </property>
   <widget class="QMenu" name="menuMenu">
    <property name="title">
     <string>Menu</string>
    </property>
   </widget>
   <addaction name="menuMenu"/>
  </widget>
  <widget class="QStatusBar" name="statusbar"/>
 </widget>
 <resources/>
 <connections/>
</ui>

使用 pyuic4 将您的 MyWidget.ui 文件编译到 Ui_MyWidget.py 中，并在您的 OS shell 命令行中使用以下命令:

Compile your MyWidget.ui file into Ui_MyWidget.py using pyuic4 with this command from your OS shell command-line:

pyuic4 "/path/to/MyWidget.ui" -o "Ui_MyWidget.py"

此命令将在您的当前目录中创建一个 Ui_MyWidget.py 文件，其中包含以下内容:

This command will create a Ui_MyWidget.py file in your current directory with this contents:

# -*- coding: utf-8 -*-

# Form implementation generated from reading ui file 'MyWidget.ui'
#
# Created: Fri Dec 28 03:45:13 2012
#      by: PyQt4 UI code generator 4.7.3
#
# WARNING! All changes made in this file will be lost!

from PyQt4 import QtCore, QtGui

class Ui_MainWindow(object):
    def setupUi(self, MainWindow):
        MainWindow.setObjectName("MainWindow")
        MainWindow.resize(147, 125)
        self.centralwidget = QtGui.QWidget(MainWindow)
        self.centralwidget.setObjectName("centralwidget")
        self.verticalLayout = QtGui.QVBoxLayout(self.centralwidget)
        self.verticalLayout.setObjectName("verticalLayout")
        self.lineEdit = QtGui.QLineEdit(self.centralwidget)
        self.lineEdit.setObjectName("lineEdit")
        self.verticalLayout.addWidget(self.lineEdit)
        self.pushButton = QtGui.QPushButton(self.centralwidget)
        self.pushButton.setObjectName("pushButton")
        self.verticalLayout.addWidget(self.pushButton)
        MainWindow.setCentralWidget(self.centralwidget)
        self.menubar = QtGui.QMenuBar(MainWindow)
        self.menubar.setGeometry(QtCore.QRect(0, 0, 147, 25))
        self.menubar.setObjectName("menubar")
        self.menuMenu = QtGui.QMenu(self.menubar)
        self.menuMenu.setObjectName("menuMenu")
        MainWindow.setMenuBar(self.menubar)
        self.statusbar = QtGui.QStatusBar(MainWindow)
        self.statusbar.setObjectName("statusbar")
        MainWindow.setStatusBar(self.statusbar)
        self.menubar.addAction(self.menuMenu.menuAction())

        self.retranslateUi(MainWindow)
        QtCore.QMetaObject.connectSlotsByName(MainWindow)

    def retranslateUi(self, MainWindow):
        MainWindow.setWindowTitle(QtGui.QApplication.translate("MainWindow", "MainWindow", None, QtGui.QApplication.UnicodeUTF8))
        self.pushButton.setText(QtGui.QApplication.translate("MainWindow", "Click Me", None, QtGui.QApplication.UnicodeUTF8))
        self.menuMenu.setTitle(QtGui.QApplication.translate("MainWindow", "Menu", None, QtGui.QApplication.UnicodeUTF8))

将此代码保存为您的 MyWidget.py 文件:

#!/usr/bin/env python
#-*- coding:utf-8 -*-

from PyQt4 import QtCore, QtGui
from Ui_MyWidget import Ui_MainWindow

class MyWidget(QtGui.QMainWindow, Ui_MainWindow):
    def __init__(self, parent=None):
       super(MyWidget, self).__init__(parent)

       self.setupUi(self)

    @QtCore.pyqtSlot()
    def on_pushButton_clicked(self):
        self.lineEdit.setText("A Qt standalone app!")

if __name__ == '__main__':
    import sys

    app = QtGui.QApplication(sys.argv)
    window = MyWidget()
    window.resize(300, 30)
    window.show()
    sys.exit(app.exec_())

检查您是否可以无错误地运行 MyWidget.py(MyWidget.py 和 Ui_MyWidget.py 需要在同一个文件夹)，一旦完成配置 PyInstaller(检查自述文件)从你的 OS shell 命令行 cd 进入 pyinstaller 目录并运行这个命令:

Check that you can run MyWidget.py without errors (MyWidget.py and Ui_MyWidget.py need to be in the same folder), and once done configuring PyInstaller (checkout the README file) from your OS shell command-line cd into the pyinstaller directory and run this command:

python pyinstaller.py --onefile '/path/to/MyWidget.py'

在 pyinstaller 文件夹中查找名为 MyWidget 的文件夹，dist 文件夹内是您的独立 Qt 应用.

Look for a folder called MyWidget in the pyinstaller folder, inside the dist folder is your standalone Qt app.
