[wxPython-users] Bound Methods

[António Barbosa (GN/dpi)]

Hi Murat,

Excuse me but I was too synthetic ;)
I will try to explain it better:

Sometimes I have to modify or debug a program made by me (or by someone els=
e) and I would like, for instance, to change the behavior of pressing a par=
ticular button.
In a small program it is very easy to do it: I only have to read a hand-ful=
l of code lines. =

But in large programs with several script files, with several classes an se=
veral dialogs, that task is not so easy!
Particularly if I am not the author or if my memory not helps me as it shou=
ld ;)

Suppose that at near the end of main script, I put something like this:

#--------------------------------------------------
class MyApp(wx.App):
	def OnInit(self):
           (...)
		self.Bind(wx.EVT_RIGHT_UP , self.OnRightClick) #only for debug!

	def OnRightClick(self, event):
		import inspect
		obj =3D wx.FindWindowAtPointer()
		name=3Dobj.GetName()+'  '+obj.GetLabel()
		A=3D[name]
		parent=3Dobj.GetParent()
		bases=3D parent.__class__.__bases__[0]
		methodList =3D [ method  for method  in dir (parent) if method  not in di=
r (bases)  and callable(getattr(parent, method)) ]
		for method in methodList:
			A.append('Method: '+method)
		method=3DmyPopUp(self.dialog_1,A) #myPopup gives a popup menu, and return=
s the choice
		myattr=3Dmethod.split()
		if len(myattr)>1:
			s=3Dgetattr(parent,myattr[1])
			script=3Dinspect.getsourcefile(s)
			line=3Dinspect.getsourcelines(s)[1]
			print 'TRACE ---->[%s]  %s  Script: "%s" line %d' %(name,method,script, =
line)
		else:
			print 'TRACE ----> [%s]' %(name)
#--------------------------------------------------

With this, I get the name of object that I am inspecting, and a list of met=
hods of parent's class.

What I would like is to show only the relevant methods: - the ones that are=
 BOUND to it!

It is possible?
I know that I can parse the class code and search for lines that have =AB.b=
ind=BB, but it is not a good solution, don't you agree?

I hope to have been more clear.
Thanks for your attention.

Antonio Barbosa

I think you already know that by saying:

bt1.Bind(wx.EVT_BUTTON, self.onButton1)
bt2.Bind(wx.EVT_BUTTON, self.onButton2)

What are you trying to do ? What is your purpose ? Can you be more specific=
 ?
