我找到了样式选项卡(笔记本)、菜单、窗口、表单和许多其他示例,但没有看到任何滚动条示例。Anyoune可以显示或提示一些关于此的内容吗?我有关于创建带有滑块和箭头的特殊wxPanel的想法,但我不知道是否可以通过在面板内拖动和单击来隐藏系统滚动条和移动内容?
我认为最接近您要做的事情是wx.lib.dragscroller
.
这是您在官方网站的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()
