MATLAB: How to call a function with a GUI push button

Matthew - if your image is being displayed in a specific axes (say named axes1) of the GUI, then you can get that data in the other callback as follows

 function pushbutton2_Callback(hObject, eventdata, handles)
 % get the image data
 I = get(get(handles.axes,'Children'),'CData');
 % do the operation on it
 Cell_Recognition(I);

We rely on the fact that the image is the only child on the axes, and so when we call

 get(handles.axes,'Children')

it just returns the graphics handle to the image object. We then get the original image data that is stored in CData.

Try the above and see what happens!

MATLAB: Is the space between items in the Pop-up menu different depending on the size of the GUI

The Xwindow server determines the space between items in a pop-up menu. The only way to make sure that the space between items in a pop-up menu does not change is to prevent the GUI from being resized. This can be accomplished by setting the GUI Option Resize Behavior to Non-resizeable. (The GUI Options dialog box is available from the Tools menu in GUIDE.)
