Call objects created within definitions

Hi,

I want to create buttons within a definition. Something like that:

Code:

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)

And afterthat I call the def like this way:

Code:

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

So I want to set the button-name manually. This works fine.

But now I want to define onbuttondown events, but this does not work!

If I write:

Code:

def onButton(obj,state):

 if obj == viz.VizButtonLabel(5):

   viz.scene( 2 )

then it works. But this isn't a very good solution. Because if I create more and more objects, I had to change the number of the buttonlabel.

So I want to write:

Code:

def onButton(obj,state):

 if obj == button1:

   viz.scene( 2 )

But this does not work! I get the error message: global name 'button1' is not defined.

I don't know how to solve this problem.

I only want to create a lot of buttons and want to set the name of the button over a parameter. And afterthat I want to check the onbuttondown event via the buttonname.

Thanks for all your answers...

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:

Code:

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. :mad:

For example:

I've got this class:

Code:

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

Code:

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??

:confused::eek:

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

Code:

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)

Yes it works!

Thank you very much....
