I have looked up some of the wxPython event handlers I have used over time. You are right there are different versions, some are outdated, some are personal preference. I prefer the version used by button4 or the mouse clicks on the parent frame ...
[php]# checking different versions of the wxPython event handler
import wx
ID_BTN1 = 1001 # give button1 a unique id number
ID_BTN2 = 1002
class MyFrame(wx.Frame):
"""make a frame with test buttons, inherits wx.Frame"""
def __init__(self):
# create a frame/window, no parent, default to wxID_ANY
wx.Frame.__init__(self, None, wx.ID_ANY, 'wxPython', pos=(200, 150), size=(320, 250))
self.SetBackgroundColour('green')
self.button1 = wx.Button(self, id=ID_BTN1, label='Button1', pos=(8, 8), size=(175, 28))
# older style event handler using the button's id number
wx.EVT_BUTTON(self, ID_BTN1, self.button1Click)
self.button2 = wx.Button(self, id=ID_BTN2, label='Button2', pos=(8, 38), size=(175, 28))
# newer style event handler (wxPython version 2.5 and higher) using Bind() and button's id
self.Bind(wx.EVT_BUTTON, self.button2Click, id=ID_BTN2)
# button uses the default id of -1
self.button3 = wx.Button(self, id=-1, label='Button3', pos=(8, 68), size=(175, 28))
# another version of Bind() identifying the button by name
self.Bind(wx.EVT_BUTTON, self.button3Click, self.button3)
self.button4 = wx.Button(self, id=-1, label='Button4', pos=(8, 98), size=(175, 28))
# one more version if Bind() identifying the button up front
self.button4.Bind(wx.EVT_BUTTON, self.button4Click)
# handle mouse events on frame
self.Bind(wx.EVT_LEFT_DOWN, self.OnLeftDown)
self.Bind(wx.EVT_RIGHT_DOWN, self.OnRightDown)
# show the frame
self.Show(True)
def button1Click(self, event):
self.SetTitle("Button1 clicked")
def button2Click(self, event):
self.SetTitle("Button2 clicked")
def button3Click(self, event):
self.SetTitle("Button3 clicked")
def button4Click(self, event):
self.SetTitle("Button4 clicked")
def OnLeftDown(self, event):
pt = event.GetPosition() # position tuple
self.SetTitle('left mouse = ' + str(pt))
def OnRightDown(self, event):
pt = event.GetPosition()
self.SetTitle('right mouse = ' + str(pt))
application = wx.PySimpleApp()
# call class MyFrame
window = MyFrame()
# start the event loop
application.MainLoop()
