Call objects created within definitions

[farshizzo]

Your createButton function should return the button object and you should save the object in a global variable with the name you want. For example:

def createButton(self, position, pictureOff, pictureOn, name, szene):
	self.Position = position
	self.PictureOff = pictureOff
	self.PictureOn = pictureOn
	self.Name = name
	self.Szene = szene
		
	name = viz.add(viz.BUTTON, scene=szene)
	name.translate(position[0],position[1])
	name.uppicture(pictureOff)
	name.downpicture(pictureOn)
	name.setScale(12,3.6)
	return name

button1 = createButton([0.25,0.8],'button01Off.jpg', 'button01On.jpg', 'button1', 2)

Hi,

thanks for your answer. But this does not work.

For example:

I've got this class:

import viz

class Button(object):
	
	def createButton(self, position, name):
		name = viz.add(viz.BUTTON)
		name.translate(position[0], position[1])
		return name

and this start.py

import viz
import button

viz.go()


button = button.Button()

button.createButton([0.2,0.5], 'testbutton')

def onButton(obj,state):
	if obj == button.testbutton:
		print 'test'

viz.callback(viz.BUTTON_EVENT,onButton)

So I want to create a button with the name testbutton. And afterthat I want to check if the testbutton is clicked.

In my example, the button got the name 'testbutton'.

But then, I've got the error message: 'Button' object has no attribute 'testbutton'


What is wrong??

You need to assign the return value of the createButton function to a variable:

import viz
import button

viz.go()


btn = button.Button()

testbutton = btn.createButton([0.2,0.5], 'testbutton')

def onButton(obj,state):
	if obj == testbutton:
		print 'test'

viz.callback(viz.BUTTON_EVENT,onButton)
