wxPython(wxWidgets):如何自定义滚动条外观&n感觉?

我找到了样式选项卡(笔记本),菜单,窗口,表单和其他许多示例,但没有看到滚动条的任何示例。可以任何显示或提示某事吗? 我有关于使用滑块和箭头创建特殊wxPanel的想法,但我不知道是否可以隐藏系统滚动条并通过拖动并单击内部来移动内容?

我认为最接近你要做的是wx.lib.dragscroller

这是您在官方网站上的wxPython演示中找到的示例:

import wx
import wx.lib.dragscroller

#-------------------------------------------------------------------------------

def runTest(frame, nb, log):
    win = DragScrollerExample(nb, -1)
    return win

class DragScrollerExample(wx.ScrolledWindow):
    def __init__(self, parent, id=-1):
        wx.ScrolledWindow.__init__(self, parent, id)
        self.Bind(wx.EVT_PAINT, self.OnPaint)
        self.Bind(wx.EVT_RIGHT_DOWN, self.OnRightDown)
        self.Bind(wx.EVT_RIGHT_UP, self.OnRightUp)

        self.SetScrollbars(1, 1, 2000, 2000, 0, 0)

        self.scroller = wx.lib.dragscroller.DragScroller(self)

    def OnPaint(self, event):
        dc = wx.PaintDC(self)
        self.DoPrepareDC(dc)

        pen = wx.Pen(wx.BLACK, 5)
        dc.SetPen(pen)

        for y in range(10):
            for x in range(10):
                dc.DrawCircle(x*400+20, y*400+20, 200)

        dc.DrawText('Right click and drag in the direction you want to scroll.',
                    20, 20)
        dc.DrawText('The distance from the start of the drag determines the speed.',                
                    20, 50)

    def OnRightDown(self, event):
        self.scroller.Start(event.GetPosition())

    def OnRightUp(self, event):
        self.scroller.Stop()
