我尝试重现您的问题,但对我来说效果很好。我能想到的唯一一件事是您的一个类也绑定到wx.EVT_KEY_DOWN,并且在其回调中没有调用wx.Event.Skip()。这将阻止对事件的进一步处理。如果您的滚动面板恰好位于事件处理程序序列中此类对象的下游,它将永远不会看到该事件。
作为参考,这是一个对我有用的示例(在 Windows 上)。你所做的与这有很大不同吗?
import wx
import wx.aui, wx.lib.scrolledpanel
class AppFrame(wx.Frame):
def __init__(self, *args, **kwds):
wx.Frame.__init__(self, *args, **kwds)
# The notebook
self.nb = wx.aui.AuiNotebook(self)
# Create a scrolled panel
panel = wx.lib.scrolledpanel.ScrolledPanel(self, -1)
panel.SetupScrolling()
self.add_panel(panel, 'Scrolled Panel')
# Create a normal panel
panel = wx.Panel(self, -1)
self.add_panel(panel, 'Simple Panel')
# Set the notebook on the frame
self.sizer = wx.BoxSizer()
self.sizer.Add(self.nb, 1, wx.EXPAND)
self.SetSizer(self.sizer)
# Status bar to display the key code of what was typed
self.sb = self.CreateStatusBar()
def add_panel(self, panel, name):
panel.Bind(wx.EVT_KEY_DOWN, self.on_key)
self.nb.AddPage(panel, name)
def on_key(self, event):
self.sb.SetStatusText("key: %d [%d]" % (event.GetKeyCode(), event.GetTimestamp()))
event.Skip()
class TestApp(wx.App):
def OnInit(self):
frame = AppFrame(None, -1, 'Click on a panel and hit a key')
frame.Show()
self.SetTopWindow(frame)
return 1
if __name__ == "__main__":
app = TestApp(0)
app.MainLoop()
