这个 python 程序在 wxpython 窗口中绘制一个图形。

如何更改程序以便：

  • 当我调整窗口大小时，图形会调整大小
  • 主窗口不能调整为小于特定尺寸？（比如说，窗口默认大小的一半）

.

1）修改你设置你的sizer的方式：

sizer.Add(self.canvas, 1, wx.EXPAND | wx.ALL)

这是方法参考。安装和使用wxPython Demo也很有帮助。Sizer 很好地覆盖在那里。顺便说一句：wx.ALL除非您指定边框，否则没用。

2）然后将其添加到您的框架设置中frame.Show()：

size = frame.GetSize()
frame.SetMinSize((size[0] / 2, size[1] / 2))
