Wxpython：在Windows和Linux中表現不同的代碼

Question

以下代碼在Windows和Linux平臺上編譯並運行良好，但需要滾動查看的字段（V_scroll）從窗口中缺失，但linux沒有這樣的問題。 wx 3.0安裝在windows和2.8.1在linux中。這會是一個問題嗎？

Answer 1

我不明白你爲什麼使用這麼多sizer，在這裏我使用FlexGridSizer代替。但你的問題是由於你使用self.SetSizer（vbox），然後self.SetSizer（sizer），第一個應該是self.scroll.SetSizer（vbox）。

有一個問題我沒有想到與以下，這是我定義wx.EXPAND的TextCtrl沒有擴大。
