新面板中的 Boxsizers

Boxsizers in a New Panel

我有一个菜单栏项目可以激活以下功能。应该会弹出一个新的 window,但我在将 sizer 放入新的 window 时遇到了问题。我更愿意在 Class Parameter1Window 下创建 window,但我一直收到变量未定义消息。我也曾尝试在函数中创建一个面板,但没有成功。我做错了什么?enter code here

也欢迎对整体结构提出建议。

解决此问题的最简单方法是将其设为单独的 class,然后从菜单 event 回调中调用它。

参见MainFrameclass中的定义onParam1和新的classParam1

作为一个单独的 class 它需要自己的 Quit 函数,这样它才能被销毁。
按钮很方便,但永远不要忘记 window.
右上角的 X 它会触发 wx.EVT_CLOSE 事件。
