Hi,
I am creating a GUI that is having checkbox. I used the uicheckbox since everytime that I am running the gui the number of checkboxes will be changed. The program first read from a csv file and according to the rows in the csv file, the checkbox will be created so that user can choose from these checkboxes.
The problem is that when I am running the program out of gui it is working perfect and the checkbox is a matlab.ui.control.checkbox. But when I am using it inside the gui, it will be a double and I can not find which ones user selected.
Can anyone help??

Inside the gui: is it possible the GUI is App Designer based?
... I think we are going to need the GUI code (and any .fig) to test with.

In testgui_OpeningFcn add the lines
global Target_checkbox
Target_checkbox = gobjects(0);
What is happening is that you are not initializing Target_checkbox, so by default it is initialized to [] which is a numeric array. When you assign a graphics handle into a double array, it automatically converts it to the old-style numeric handles.

Initializing to gobjects() would be useful for a property that will eventually be a graphics object.
