wxPython几何问题

Question

我正在尝试使按钮位于标签的右边。 我设置了元组，但仍不确定为什么它覆盖了标签。

还有关于wxpython几何的很好的教程吗？

def GetRoundBitmap( w, h, r ):

    dc = wx.MemoryDC(b)
    dc.SetBrush(wx.Brush(maskColor))
    dc.DrawRectangle(0,0,w,h)
    dc.SetBrush(wx.Brush(shownColor))
    dc.SetPen(wx.Pen(shownColor))
    dc.DrawRoundedRectangle(0,0,w,h,r)
    dc.SelectObject(wx.NullBitmap)

        else:

            displacement = self._dragPos - pos
            self.SetPosition( self.GetPosition() - displacement )



app = wx.App()
f = FancyFrame()
app.MainLoop()

Answer 1

您忘记将FancyFrame设置为具有给定的布局大小。

换句话说，您需要在FancyFrame的__init__方法的末尾添加一行。

self.SetSizerAndFit(geo)
