從Windows遷移到Linux時的WXPython界面無法正常工作

Question

我幾乎完成了我的圖形界面的試用版。我在Windows上做了這個，然後我轉移到Linux來測試它。 我遇到的問題是Matplotlib面板正在被切割（僅在Linux版本上），所以我看不到圖形。我不能調整大小來解決這個問題。

下面你可以看到我的代碼。有任何想法嗎？

Answer 1

您遇到的主要問題是，您要添加的孩子拆分窗口的到BoxSizerself.box，當你要添加拆分窗口本身。

而是寫作的

 self.box.Add(self.p1, 1, wx.EXPAND) 
     self.box.Add(self.p2, 1, wx.EXPAND) 

寫

 self.box.Add(self.sp, 1, wx.EXPAND) 

你還需要告訴拆分窗口拆分哪種方式，水平或垂直使用，例如

 self.sp.SplitVertically(self.p1, self.p2) 

最後，因爲您沒有使用Sizer作爲您的MainPanel，所以您可能需要設置它的最小尺寸。我發現如果我沒有給它一個最小尺寸（或者沒有使用SetMinimumPanelSize來限制分隔窗口中窗格的最小尺寸），那麼分隔窗口根本沒有顯示MainPanel。嘗試加入以下的MainPanel.__init__底部（更改數字，如果你願意的話）：

 self.SetMinSize((350, 350)) 

我在openSUSE 12.3的x64使用wxWidgets/wxPython的2.9.4關於Python 2.7.3，有沒有什麼幫助。
