我有多个小部件,形式如下:
self.sl_qZone1 = wx.Slider(self, -1, 50, integer=True, 0, 100, size=(sliderWidthHeight), style=wx.SL_HORIZONTAL)
self.tc_qZone1 = wx.TextCtrl(panel, -1, 50, (0,0), style=wx.TE_CENTER)
我有一些事件像这样绑定到十几个滑块/文本控件:
wx.FindWindowByName(mvName['sl0']).Bind(wx.EVT_SLIDER, lambda event: self.sliderUpdate(event, wx.FindWindowByName(mvName['sl0']), wx.FindWindowByName(mvName['tc0']),), wx.FindWindowByName(mvName['sl0']))
wx.FindWindowByName(mvName['tc0']).Bind(wx.EVT_CHAR, lambda event: self.tcVolUpdate(event, wx.FindWindowByName(mvName['sl0']), wx.FindWindowByName(mvName['tc0']),), wx.FindWindowByName(mvName['tc0']))
然后我有这些功能:
def sliderUpdate(self, event, slider, textctrl):
textctrl.SetValue(str(slider.GetValue()))
def tcVolUpdate(self, event, slider, textctrl):
slider.SetValue(int(textctrl.GetValue()))
修改滑块时效果很好 - 它使用适当的值更新textctrl。但是当我尝试编辑textctrl时,它让我选择文本但不实际编辑它。我也尝试了wx.EVT_TEXT_ENTER
而没有运气。
如何使文本ctrl可更新并让它更新滑块的值?

在textctrl上设置样式以包含wx.TE_PROCESS_ENTER,然后您可以在绑定上使用EVT_TEXT_ENTER。
