Problem with ImageButton attributes

[TomasBar]

Hello,

I have defined an image button in a form thus:

image_button=twf.ImageButton(modname = 'tw2.forms', filename = 'static/info.png',alt='Info')

Whenever it gets clicked, I get the following error message:

keywords must be strings

I have tried to define the attributes like this instead:


image_button=twf.ImageButton(attrs={'modname' : 'tw2.forms', 'filename' : 'static/info.png','alt':'Info'})

But then I get the following error message:

ParameterError: Either 'link' or 'filename' must be specified

Many thanks for any help.

Tomas
