从 wxPython 应用程序中的框架和面板中删除边框

Question

我正在构建一个应用程序，该应用程序应在左侧包含可调整大小的侧边栏区域（从 200 像素宽度开始）和右侧应扩展以填充剩余区域的主要区域。我已经使用了SplitterWindow 方法，因为它是我认为唯一在面板上提供手动调整大小的方法。我在各个面板和整个框架周围遇到了一些我似乎无法摆脱的黑色边框。当我注释掉make_canvas 调用时，各个面板上的边框消失了，但框架上的边框仍然存在。奇怪的是，如果我调整整个应用程序窗口的大小，边框会闪烁。我怀疑这实际上不是边界问题，而是BoxSizing 问题，但我不知道如何处理它。

代码如下：

    def __init__(self, parent):
        wx.TaskBarIcon.__init__(self)

您正在通过调用DrawRectangle 绘制这些线条。 如果您想消除线条并仍然绘制矩形，您可以这样做：

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

在两个make_canvas 方法中。它适用于 Windows。
