From: Jim Hokanson on 3 Mar 2010 03:32 When looking at a bunch of a figures I tend to plot them in a loop and then use the pause function to allow keying between plots. Unfortunately if dbstop if error is true, then ctrl+c'ing out of it throws an errror. I tried catching and ignoring the error but the error couldn't be caught. I instead tried waitforbuttonpress, but there is no option to limit this to only a mouse or a keyboard input, which means when I start using the mouse on the figure the plotting continues. Hopefully the goal is clear, any suggestions or workarounds? Thanks.

Thanks. See the help of WAITFORBUTTONPRESS. function WaitForMouseButton % WaitForMouseButton - Pause until the user clicks a mouse button % This function uses the current figure, or creates a new figure of none exists. while waitforbuttonpress ~= 0 ; pause(0.1) ; % allow for ctrl-c end hth Jos
From: Jim Hokanson on 3 Mar 2010 12:43 Thanks Jos, I should have clarified on that in my post. That function takes over the mouse listener which means I cannot use the mouse on the figure. i.e. I click on the figure with the mouse and instead of getting the desired function, such as zooming on a figure, I just run another iteration of the loop. I'm thinking I might just use get(gcf,'CurrentCharacter') with a try/catch around it in case it is closed (or something like that). Jim
