Python wxwidgets bind key 'Ctrl + C'

處理原生 EVT_KEY_DOWN 事件

    self.Bind(wx.EVT_KEY_DOWN, self.on_key_down)

    def on_key_down(self, event):
        """Key down event handler."""
        key = event.KeyCode()
       
        controlDown = event.ControlDown()
        altDown = event.AltDown()
        shiftDown = event.ShiftDown()

        # Cut to the clipboard.
        if (controlDown and key in (ord('C'), ord('c'))):
            copy()
        # Insert the next command from the history buffer.
        else:
            event.Skip()

使用 wx_tools class

import wx_tools
class Frame(wx.Frame):
    def __init__(self, *args, **keywords):
       self.__init_key_handlers()

    def __init_key_handlers(self):

        '''Initialize key shortcuts.'''

  

        self.Bind(wx.EVT_KEY_DOWN, self.on_key_down)

 

        def copy():

            print 'copy'




        self.key_handlers = {

            Key(ord('C'), cmd=True): copy,

         }




    def on_key_down(self, event):

        '''wx.EVT_KEY_DOWN handler.'''

        key = Key.get_from_key_event(event)

        handler = self.key_handlers.get(key, None)

        if handler:

            handler()

        else:

            event.Skip()

python wxwidgets 捕捉 Alt+F4

1. 捕捉 wxwidgets 窗口關閉事件

    self.frame.Bind(wx.EVT_CLOSE, self.OnClose)

    def OnClose(self, evt):
        print 'cannot close'

#        dlg = wx.MessageDialog(None, "Is this explanation OK?",
#                'A Message Box',
#                wx.YES_NO | wx.ICON_QUESTION)
#        retCode = dlg.ShowModal()
#        if (retCode == wx.ID_YES):
#            self.frame.Destroy()
#            print "yes"
#        else:
#            print "no"

2. 捕捉 wx 快捷鍵 (wx.EVT_HOTKEY) (不能使用 wx.EVT_KEY_DOWN 事件捕捉快捷鍵)

 import win32con  #for the VK keycodes
 

    def regHotKey(self):
        self.hotKeyId = 100
        self.frame.RegisterHotKey(
            self.hotKeyId, #a unique ID for this hotkey
            win32con.MOD_CONTROL + win32con.MOD_SHIFT , #the modifier key
            win32con.VK_DELETE) #the key to watch for

        self.regHotKey()

        self.Bind(wx.EVT_HOTKEY, self.OnClose, id=self.hotKeyId)

3. 捕捉系統快捷鍵
