Plugin development: How to get value of image window channel/slice when user changes channel/slice?

[MrScientistman2]

Dear all,

I am developing a ImageJ (v1.51) plugin, which take some input data from an image file, filters it, and displays it in a output image window. The plugin uses a swing frame with some buttons to add more filters etc. The problem is that I want to have a text field in my swing frame which shows the value corresponding to which current channel/slice that is viewed/selected in the output image window. So basically, every time the user changes the channel/slice of the output image window, my swing frame should update which channel/slice is displayed/viewed. Since I am not handling the output image window with swing myself I don't know how to get an event listener attached to the output image window. Anyone got some pointers or ideas?

Cheers

Hello Anders,


I don't know if there are better options, but I've done something like that using a Thread that updates at regular time intervals. The piece of code is attached (I rewrote a part of it, so there may be some bugs).


Cheers,


Nicolas
