Using variables in multiple Callbacks
6 views (last 30 days)

I have two different pop up menu callbacks (popupmenu1 and popupmenu2). In both callbacks I produce a variable, urlA and urlB respectively. How can I use these variables in my pushbutton1 call back? Created GUI using GUIDE. I've read the documentation and help on handles, but I can't quite get anything working.
I tried using global variables, but it isn't working quite as it should.

You can first store the variable in a structure inside one of the Callback functions. Look at the example below:
function first_callback(hObject,handles)
handles.myvariable=urlA
guidata(hObject,handles)
end
Then you can retrive the stored structure in the other callback function:
function second_callback(hObject,eventdata)
guidata(hObject)%This will give back the variable "urlA" from previous callback function
end
