I am trying to make my check box for my gui either disp 'showHistory' or 'hideHistory' depending on whether the the box is checked I figured out how to make is so that when the box is checked that it is disp 'showHistory' but I dont know how to do the second part of this question. Here is my script so far:
figure;
first_button = uicontrol('style', 'pushbutton');
set(first_button, 'units', 'normalized', 'position', [0.2,0.7, 0.2, 0.2])
set(first_button, 'string', 'turn left')
set(first_button, 'callback', @turnLeft)
second_button = uicontrol('style', 'pushbutton');
set(second_button, 'units', 'normalized', 'position', [0.4, 0.7, 0.2, 0.2])
set(second_button, 'string', 'step')
set(second_button, 'callback', @step)
third_button = uicontrol('style', 'pushbutton');
set(third_button, 'units', 'normalized', 'position', [0.6, 0.7, 0.2, 0.2])
set(third_button, 'string', 'turn right')
set(third_button, 'callback', @turnRight)
fourth_button = uicontrol('style', 'pushbutton');
set(fourth_button, 'units', 'normalized', 'position', [0.2, 0.5, 0.2, 0.2])
set(fourth_button, 'string', 'left')
set(fourth_button, 'callback', @turnLeft)
fifth_button = uicontrol('style', 'pushbutton');
set(fifth_button, 'units', 'normalized', 'position', [0.4, 0.5, 0.2, 0.2])
set(fifth_button, 'string', 'back')
set(fifth_button, 'callback', @step)
sixth_button = uicontrol('style', 'pushbutton');
set(sixth_button, 'units', 'normalized', 'position', [0.6, 0.5, 0.2, 0.2])
set(sixth_button, 'string', 'right')
seventh_button = uicontrol ('Style','checkbox');
set(seventh_button, 'units', 'normalized', 'position', [0.2, 0.3, 0.2, 0.2])
set(seventh_button, 'string', 'History')
set(seventh_button, 'callback', @toggleHistory)
eighth_button = uicontrol ('style', 'edit');
set(eighth_button, 'units', 'normalized', 'position', [0.4, 0.37, 0.2, 0.05])
set(eighth_button, 'string', '2')
ninth_button = uicontrol('style','pushbutton');
set(ninth_button, 'units', 'normalized', 'position', [0.6, 0.3, 0.2, 0.2])
set(ninth_button, 'string', 'Run!')
function toggleHistory(sender, evendata)
disp('showHistory')
end

In the toggleHistory callback, use an if condition to check the value of the checkbox.
if sender.Value == 1
disp showHistory
else
disp hideHistory
end
