使用Qt Designer开发上位机
一、安装第三方库
使用pip命令安装第三方库
pip install PyQt5 -i https://pypi.tuna.tsinghua.edu.cn/simple
pip install pyqt5-tools -i https://pypi.tuna.tsinghua.edu.cn/simple二、使用designer设计界面
1、找到对应的designer.exe，双击进入界面设计。
2、创建一个主界面。
2.1 实现一个按钮弹窗的功能
1、拖出来一个按钮
2、关联UI背后的动作事件
3、保存.ui文件
pyuic5 -o main.py .\main.ui4、把生成的.ui文件生成对应的py文件
5、手动实现按钮背后的逻辑
2.2 测试
测试ok
三、源码
