Hi Matlab community!

1 - I'd like to know if there is a method to display (on a gui) instant help like a flag with some instructions relative to specific buttons or graphs or other objects. I have a commercial software here written in Matlab that uses this feature.

2 - Another question is: it's possible to automatically (something "relative" not "absolute") stretch the panels, text and graphs? Because I read that is not possible to put inside a gui scroll bars (better solutions would be for me). Because I have a GUI now and I need to run on different size monitors.

Thanks a lot!

1) You can set the Tooltipstring property of the uicontrol; see http://www.mathworks.com/help/matlab/ref/uicontrol_props.html#bqxoiq8

2) by default the units for sizes for figures and panels and axes is "normalized units" -- fraction of the containing object. Define your objects in terms of the fraction of the screen they should take and they will automatically adjust as you change resolutions.
