PyQt界面绘制及py转换调用

1、首先相关库安装：

      pip install PyQt5
      pip install PyQt5-tools

2、安装好后配置pycharm

File-->Setting-->Tools-->External Tools-->+新增-->edit Tool

Qt Designer中的参数配置：

        Program（pyqt5_tools对应的安装文件路径）：D:\python\Lib\site-packages\pyqt5_tools\Qt\bin\designer.exe

        Working directory（统一设置）：$ProjectFileDir$

PyUIC中的参数配置：

        Program（python安装目录）：D:\python\python.exe

        Argument（统一设置）：-m PyQt5.uic.pyuic $FileName$ -o $FileNameWithoutExtension$.py

        Working directory（统一设置）：$ProjectFileDir$

        注意空格，否则会报\xa0路径错误。

3、配置完毕后，在pycharm工程目录中，单击工程右键，选择External Tools 中我们设置好的Qt Designer进入（或者从Tools 中进入 External Tools ）QT界面编辑就行，界面编写完毕后点击file保存：

4、对编辑保存好的UI文件进行.py转换，转换完后在工程中会生产对应的.py文件：

5、在生产的.py文件末尾加入以下代码进行运行，如果运行报错，更加相应的错误进行修改，注意

class Ui_MainWindow(object):名和if中的Ui_MainWindow要一直，如果有其他错误可能是本版本不支持相应的组件功能，注释掉就行，一般情况下不影响使用：

if __name__=="__main__":
    import sys
    app=QtWidgets.QApplication(sys.argv)
    widget=QtWidgets.QWidget()
    ui=Ui_MainWindow()
    ui.setupUi(widget)
    widget.show()
    sys.exit(app.exec_())
