How to pull data of UIcontrol objects from the figure handle

Hello everyone!

I have created a function which pops up a figure with UIcontrol objects on it (radio buttons, edit-text boxes and check-boxes).

I want to export data from those objects into an excel file after a push-button is pressed. So, I have a callback function for this button, and it is receiving a handle to the figure (which, from my understanding, holds the other objects as "children"?)

How can I get the data of those object from the figure handle? And if not possible, how would you recommend doing such a thing?

Thank you so much! Jasmine

Please note that there is no callback for when a pushbutton is released, only for when it is pushed

Normally you would keep track of your objects somehow (such as with a "handles" structure using guidata(), the way that GUIDE does), or you would set the Tag field for each uicontrol to something unique so that you can locate them:

currentfig = ancestor(gcbo,'figure');
eta9_handle = findobj(currentfig, 'tag', 'Eta_9');   %to locate the one you tagged with Eta_9

If you just want them all and will determine an order afterwards then:

currentfig = ancestor(gcbo,'figure');
object_handles = findobj(currentfig, 'type', 'uicontrol');

or you can look for a particular variety:

currentfig = ancestor(gcbo, 'figure');
push_handles = findobj(currentfig, 'type', 'uicontrol', 'style', 'pushbutton');
