GUIDE Example: Share Data Between Two Apps
Here is a prebuilt GUIDE app that uses application data and the guidata function to share data between two dialog boxes. When you enter text in the second dialog box and click OK, the button label changes in the first dialog box.
Click the button displayed here to open the example. Run the app by clicking the green Run Figure button at the top of the changeme_main.fig GUIDE window.
In changeme_main.m, the buttonChangeMe_Callback function executes this command to display the second dialog box:
The handles.figure input argument is the Figure object for the changeme_main dialog box.
The changeme_dialog function retrieves the handles structure from the Figure object. Thus, the entire set of components in the changeme_main dialog box is available to the second dialog box.
