在wxPython應用程序中從框架和麪板中刪除邊框

Question

我正在構建一個應該包含左側可調整大小的側欄區域（從200px寬度開始）和右側應展開以填充其餘區域的主區域的應用程序。我已經使用了SplitterWindow方法，因爲它是我認爲可以在面板上調整大小的唯一方法。我在個別面板周圍出現了一些黑色邊框，整個畫面我都無法擺脫。當我註釋掉make_canvas調用時，單個面板上的邊框消失，但框架上的邊框仍然存在。奇怪的是，如果我調整整個應用程序窗口的邊界閃爍開啓和關閉。我懷疑這實際上不是邊界問題，而是一個BoxSizing問題，但我不確定如何照顧它。

下面的代碼：

class TDTaskBarIcon(wx.TaskBarIcon): 

    def __init__(self, parent):

對此提出建議？

您正在致電DrawRectangle正在繪製這些行。 如果你想消除的線條和畫還是可以做的長方形：

dc.SetPen(wx.Pen("WHITE",1)) 
dc.DrawRectangle(0, 0, w, h) 

兩個 make_canvas方法

。它在Windows中工作。
