Hello,
I wanted to add something else to this but for some reason it didn't work.
Here is what I did: In the MainClass I created a picture and a text then I
used MakeStat on the tag. The result looks like this:
Img={QTk.newImage photo(url:'picb.gif')}
Img2={QTk.newImage photo(url:'newpicb.gif')} % the new picture to replace
the old one
{self.canvas create(image x y image:Img tags:Tag)}
{self.canvas create(text x y text:'Mytext' tags:Tag)}
After passing the StatTag and Img2 to the PicClass I made the picture move
using "move" on the tag.
Here is where it doesn't work, I wanted to change the picture and the text
from within the PicClass using the following:
{self.tag set(image:self.newImg)} % tag contains the StatTag and newImg
contains Img2
{self.tag set(text:'NewText')}
This did not work and neither the picture nor the text changed. When I tried
removing the line "{self.tag set(text:'NewText')}" the picture changed and
obviously the text didn't. How can I make it work?
Thanks
