PyQt+PyCharm

我是靠谱客的博主帅气石头，这篇文章主要介绍PyQt+PyCharm，现在分享给大家，希望可以做个参考。

本文描述Windows系统下如何安装Python + PyCharm + PyQt5，并通过PyQt5 采用两种方式设计GUI界面。a.直接使用代码设计界面；b. 先使用QtDesigner进行可视化设计，然后将生成的.ui文件转换成.py文件。

安装python（本人3.7）

安装PyQt

复制代码

1
2
3
pip install PyQt5
pip install PyQt5-tools

安装pyCharm（可自行破解）

配置：
1，点击：File -》Settings
2，Tools -》 External Tools -》点击“+”号
3，设置Qt Designer
修改三个地方，其他地方默认：

复制代码

1
2
3
4
Name：Qt Designer
Programs：C:UserscdAnaconda3Libsite-packagespyqt5_toolsdesigner.exe
Working directory：$ProjectFileDir$

注意：Programs参数需要修改为你电脑里边的“designer.exe”路径。

4，配置PyUIC

设置四个地方，其他可以默认

复制代码

1
2
3
4
5
Name：PyUIC
Programs：C:UserscdAnaconda3python.exe
Parameters：-m PyQt5.uic.pyuic  $FileName$ -o $FileNameWithoutExtension$.py
Working directory：$ProjectFileDir$

注意：Programs参数需要修改为你电脑里边的python“python.exe”路径。

四、使用Qt Designer
1，完成以上步骤之后，点击 Tools -》External Tools -》Qt Designer 启动我们的Qt Designer。

2，启动后选择：Widget，建立空白的窗口，点击 Create，其他默认就行

3，从左边 1区拖拽，注意是“拖拽”控件到工作区，修改对应属性

4，做完基本的界面设置之后，会看到同目录下生成了一个“.ui”的文件

5，右键 External Tools -》PyUIC ，将“.ui”文件转为“.py”文件

6，这时，如果一切正常，没有报错的话，会在同目录下生成对应的“.py”文件

7，将下面的代码，放到生成的“.py”文件，放到最后就行（注意缩进）

复制代码

if __name__=="__main__":
    import sys
    from PyQt5.QtGui import QIcon
    app=QtWidgets.QApplication(sys.argv)
    widget=QtWidgets.QWidget()
    ui=Ui_Form()
    ui.setupUi(widget)
    widget.setWindowIcon(QIcon('web.png'))#增加icon图标，如果没有图片

可以没有这句

复制代码

widget.show()
sys.exit(app.exec_())

8，运行启动，开启了pythonGUI旅程

9，源代码：
