Each component has properties that you can access from any callback. For example, if I have a drop down, a check box and an edit box, I could access the selected/entered value in a callback as follows:
% DropDown
value = app.DropDown.Value;
item = app.DropDown.Items(value)
% EditField
value = app.EditField.Value;
% Button
value = app.Button.Value;
% CheckBox
value = app.CheckBox.Value;
Your code can then use these values to create your desired results.
Here's an example of a button that, when pressed, populates a list box (SelectedListBox) with with values from a second list box (ListBox)
% Button pushed function: Button
function ButtonPushed(app, event)
app.SelectedListBox.Items = [app.SelectedListBox.Items app.ListBox.Value];
end
