Tk - change image on event

[PDexter]

Hi,

I'm a little new to Tk so hope this isn't a dumb question.

I've created a window using Tk and I'd like to change a gif image based on an event in my mainloop (change a green check to a red stop sign). I'm using a label widget right now but I could use a different one. This is easy for text using the message or label widget because of -textvariable option. Unfortunately there isn't an -imagevariable option.

Any ideas on a event driven image change?

Thanks.

You should be able to just make a simple callback for whatever the event is. In that (possibly anonymous) sub, do whatever work needs to be done to swap the images.

Thanks for the reply,

What I'm struggling with is the event is not user driven and coming from a button or other "normal" event. What I'm trying to do is when a value in my mainloop exceeds a certain value, then I want to change the image displayed in the Label. Most references I've found all are similar to your response where the event is triggered by a user.

Thanks again for any ideas.

Try looking at the Tk:rogressBar module and the update function as well. You should find what you are looking for there. The progress bar checks a variable and the update forces the info within the variable to update the widget.
