        <file>components/ZButton.qml</file>
        <file>main.qml</file>
    </qresource>

    Layout.preferredWidth: 100
    Layout.preferredHeight: 100
    Layout.fillHeight: false
    Layout.fillWidth: false
    Layout.alignment: Qt.AlignHCenter
    Layout.topMargin: 48
    source: "qrc:/imgs/app_min.png"
}

编译

1
pyside2-rcc resources.qrc -o resources_rc.py

打包

安装pyinstaller

1
pip install pyinstaller==6.11.1

一般打包

1
pyinstaller main.py -y --noconsole --name="xh-marking-client" --icon="logo.ico"

排除DLL

打包，同时会自动生成spec文件

1
pyinstaller main.py -y --noconsole --name="xh-marking-client" --icon="logo.ico"

修改spec文件

使用修改后的spec文件打包

1
pyinstaller xh-marking-client.spec --clean -y

设置VSCode任务

项目根目录创建.vscode文件夹

添加文件tasks.json

先编译后执行脚本

  "tasks": [
    {
      "label": "编译",
      "type": "shell",
      "command": "pyside2-rcc resources.qrc -o resources_rc.py",

运行任务直接用快捷键Ctrl+Shift+B

运行时再点击快捷键Ctrl+Shift+B可以选择重启任务或者终止任务
