python - wxpython can't capture EVT_KEY_DOWN enent -
i can't capture evt_key_down event. can capture evt_key_up.
python version : 2.7.3
wxpython version : 2.8.12.1 (gtk2-unicode)
system info: mint 14 nadia , linux 3.5.0-17-generic(x86_64)
following code
#!/usr/bin/env python import sys, os import wx class winframe(wx.frame): def __init__(self, parent, title): super(winframe, self).__init__(parent, title=title, size=(400,400)) self.panel = wx.panel(self,-1, size=(400,400)) self.panel.bind(wx.evt_key_down, self.onkeydown) self.panel.bind(wx.evt_key_up, self.onkeyup) def onkeyup(self, event): print 'up' def onkeydown(self, event): print 'down' class picsampleapp(wx.app): def __init__(self): super(picsampleapp, self).__init__(0) def createframe(self): self.frame = winframe(none, "test") self.frame.show(true) self.settopwindow(self.frame) app = picsampleapp() app.createframe() app.mainloop()
i've had problems capturing wx.evt_key_down , wx.evt_key_up. explanation of why bit on head, know switching evt_char_hook trick me. try this:
#!/usr/bin/env python import sys, os import wx class winframe(wx.frame): def __init__(self, parent, title): super(winframe, self).__init__(parent, title=title, size=(400,400)) self.panel = wx.panel(self,-1, size=(400,400)) self.panel.bind(wx.evt_char_hook, self.onkeypress) def onkeypress(self, event): keycode = event.getkeycode() if keycode == wx.wxk_down: print 'down' elif keycode == wx.wxk_up: print 'up' class picsampleapp(wx.app): def __init__(self): super(picsampleapp, self).__init__(0) def createframe(self): self.frame = winframe(none, "test") self.frame.show(true) self.settopwindow(self.frame) app = picsampleapp() app.createframe() app.mainloop() you might want put event.skip() @ bottom of onkeypress if want event continue propagating.
