A function that I am using is opening a new waitbar everytime I open it:

>> waitbar(0,'Please wait...')

Since I will be calling this function repetitively from my script file, I will have a lot of these waitbar windows opened.

Adding the following to my script does not help:

>> close all

How can I close the "waitbar" windows programmatically?

Answer 1

You can use the "findall" function and 'TMWWaitbar' as the 'tag' input to get handles to all the waitbars:

>>F = findall(0,'type','figure','tag','TMWWaitbar')

and then delete all of them:

>> delete(F)
