KeyPressFcn and WindowKeyPresFcn unable to initiate a callback function, opens command window instead (2019b).

Hey there,

I'm trying to map a specific key to activate a callback within my matlab gui figure. However, whenever a key is pressed, this key is forwarded to the command window instead. I have already viewed the following answer, however this fix did not work (https://au.mathworks.com/matlabcentral/answers/385499-in-matlab-r2017a-how-do-i-change-the-focus-of-the-windowkeypressfcn-figure-callback-function-from). Any ideas about how to force the gui figure to remain in focus to actually call the callback function?

Cheers.

My experience is that when you activate zoom/pan/rotate on the figure, then the WindowKeyPressFcn are changed by zoom and pan and the focus steel reveals that fact.

make sure then the interactive tools are off.

Hey Bruno,

You were right on the money about the zoom disabling the KeyPressFcn. I managed to disable the listening handles and I was able to call my function.

Thanks heaps!
