2008-07-17 13:25:24 [wxpython-users] what receives mouse events?
Hello,
I am little confused with mouse events. I want to do something when my object is clicked, so I used: something.Bind(wx.EVT_LEFT_DOWN,self.OnClick) It doesn't work when something is wx.Panel, it also doesn't work when something is wx.Bitmap, but it works when I call wx.InitAllImageHandlers() first. I also tried to use something.CaptureMouse(), it worked, but I don't know how to disable capture, so after I destroy object - application goes unstable. Could you explain me what is proper way to make sure that my object receives all mouse events? How can I do it for wx.Panel? Or for wx.Bitmap? -- Free Software - find interesting programs and change them NetHack - meet interesting creatures, kill them and eat their bodies Usenet - meet interesting people from all over the world and flame them Decopter - unrealistic helicopter simulator, get it from http://decopter.sf.net <div dir="ltr">Hello,<br><br>I am little confused with mouse events.<br>I want to do something when my object is clicked, so I used:<br><br>something.Bind(wx.EVT_LEFT_DOWN,self.OnClick)<br><br>It doesn't work when something is wx.Panel, it also doesn't work when something is wx.Bitmap, but it works when I call wx.InitAllImageHandlers() first.<br> I also tried to use something.CaptureMouse(), it worked, but I don't know how to disable capture, so after I destroy object - application goes unstable.<br><br>Could you explain me what is proper way to make sure that my object receives all mouse events?<br> How can I do it for wx.Panel?

Below is an example and at the bottom is the bind methods to use. Note that a left mouse click is a mouse event and also a command level where it is seen on all levels. So you have to set a test inside the bind method function to test for the mouse id, the important part is the id tag which will tell you where it is coming from. My key event example you will note the immediate event.skip for this is so the event is passed on to all other levels. Now if you want certain keys or events to stop when captured then you must do an if/else statement. if event?: do any test... else: event.skip() # Creating the menubar. menuBar = wx.MenuBar() menuBar.Append( filemenu,"&File") # Adding the "filemenu" to the MenuBar menuBar.Append( voicemenu,"&Voice") # Adding the "voicemenu" to the MenuBar self.SetMenuBar(menuBar) # Adding the MenuBar to the Frame content. self.data4menu = {} for o in self.items4menu["File"]: wx.EVT_MENU(self, o[ID], o[MF]) self.data4menu[ o[ID]] = o for o in self.items4menu["Voice"]: wx.EVT_MENU(self, o[ID], o[MF]) self.data4menu[ o[ID]] = o for o in self.items4menu["Settings"]: wx.EVT_MENU(self, o[ID], o[MF]) self.data4menu[ o[ID]] = o wx.EVT_MENU(self, o[ID]+DW_ID, o[MF]) self.data4menu[ o[ID]+DW_ID] = o self.sizer2 = wx.BoxSizer(wx.HORIZONTAL) self.buttons=[] self.data4buttons={} i=0 for o in self.buttons4voice: self.buttons.append( wx.Button(self, o[ID], o[HK]+o[KD])) self.sizer2.Add( self.buttons[i], 1, wx.EXPAND) self.data4buttons[ self.buttons[i].GetId()] = o self.buttons[i].Bind(wx.EVT_ENTER_WINDOW, o[MF]) #, id=self.buttons[i].GetId()) self.buttons[i].Bind( wx.EVT_RIGHT_DOWN, o[MF2]) #, id=self.buttons[i].GetId()) self.buttons[i].Bind( wx.EVT_BUTTON, o[MF2]) #, id=self.buttons[i].GetId()) i+=1 . . . def OnEnter(self, event): "WHEN ENTERING SAY LABEL OF BUTTON!" # self.button2bind = self.Bind(wx.EVT_BUTTON, self.OnClick, id=event.GetId()) eventType = event.GetEventType() # tts.Speak( event.GetPosition()) label4btn = self.data4buttons[ event.GetId()][0] # tts.Speak( label4btn) if label4btn == "Voice": set_value = tts.getVoiceName() elif label4btn == "Rate": set_value = str( tts.getRate()) elif label4btn == "Pitch": set_value = str( tts.getPitch()) elif label4btn == "Volume": set_value = str( tts.getVolume()) text = label4btn +" Button " +set_value tts.Speak( text, async, purge) def OnVoice(self, event): "CHECK IF DOWN KEY FOR VOICE SETTING!" wx.EVT_KEY_DOWN(self, self.OnClick) self.OnClick( event) def OnClick(self, event): "BUTTON CLICKED ON AND IN FUTURE GET BUTTON POS!" #comment tts.Speak( 'Event Name: %s Time Stamp: %s ' % (event.GetClassName(), event.GetTimestamp())) #comment print 'Event Name: %s Time Stamp: %s ' % (event.GetClassName(), event.GetTimestamp()) #comment IF KEY EVENT: #comment key = event.GetKeyCode() #comment pos = event.GetPositionTuple() eventType = event.GetEventType() #comment if eventType == wx.EVT_BUTTON: print "Mouse!
