MATLAB GUI: Make a list of selection from a cell array containing string in popup menu

Hi All,

I want to make a GUI whick looks like below. After I imported the data from my workspace to GUI. I want to make a cell array(handles.StepName) containing step names into a list of selection under the select simulation step popup menu. but it didn't work and I got no idea how to do it.

another thing: I want to connect the input selection in the other popup menu (select surface) to the next popup. the first popup will select X_SB,Y_SB and Z_SB, if substrate bottom is selected in th first popup. later, the second popup(select simulation step) will specifiy matrix in struc handles.X_SB, handles.Y_SB and handles.Z_SB to be selected i.e. for step 1, following matrix will be choosen: handles.X_SB.Step1, handles.Y_SB.Step1 and handles.Z_SB.Step1.

can anyone guide me with this ?

thanks

It sounds like you have a fairly good idea about what you want to happen. However, it is not clear to me. What is clear to me is that you're using GUIDE, which is not a good strategy for anything you're going to spend more than an hour making. For general advice and examples for how to create a GUI (and avoid using GUIDE), have look at this thread.

[Abdul Rasyid Haron]

so do I need to change to use AppDesigner then?

since I have invested some time using GUIDE, could you maybe help with that? what part that you don't understand?

[Rik]

If you don't bother to click the link, why should I bother responding to your comment? There are many ways to create a GUI in Matlab, GUIDE and AppDesigner are only two of them. I'm just suggesting you should not use GUIDE.

When re-reading your question it seems you have painted yourself in a corner. Why did you number the struct fields? Why not use a struct array instead? Then you could simply use normal indexing to select the correct data.

If you want a cell array listing the field names of a struct, you can use the fieldnames function.

[Abdul Rasyid Haron]

As you suggested, I made the GUI using codes like below. But, I got error message 'Invalid use of operator'. I can't find any operator issue here.

can you have a look at my code and help me?

You can't define inputs as fields of a struct. You're better off dynamically loading the data on callback:

function plotSurface(hObject, eventdata)
%this will load handles.popupmenu1 and handles.listbox
handles=guidata(hObject);
