image processing - How to disable a button on the uigetpref dialogue in MATLAB? -

i developing tool image processing on matlab using guide. have small snag correct in it. question is:

*

the user asked select 1 of 2 images on tool (in different axis) , handle of image passed on using function further processing. using function uigetpref purpose. want disable 1 button on dialogue when condition true. how can that? documentation not list such option.

• the instruction:

  selectedbutton = uigetpref(... 'mygraphics',...                            % group 'imageselection',...            % preference 'select image',...                        % window title {'please select picture enable labelling on.'  ''  'the labelled points shown in other 2 axes after completion'},... {1,2;'image a','image b'},...        % values , button strings  'extraoptions','cancel',...                % additional button  'defaultbutton','image a',...      % default choice  'helpstring','help',...                    % string button  'helpfcn','doc(''axes'');'); 

thank you.

if want button grayed out or disabled, you're going need either construct own dialog instead of using uigetpref, or you're going need somehow find hidden handle uigetpref dialog, , manually gray out button.

if have button display or not display depending on condition, try code:

mycondition = true; % mycondition = false % uncomment test  switch mycondition     case true         buttondetails = {1,2;'image a','image b'};         defaultbutton = 'image b';     case false         buttondetails = {1;'image a'};         defaultbutton = 'image a'; end          selectedbutton = uigetpref(... 'mygraphics',... 'imageselection',... 'select image',... {'please select picture enable labelling on.'  ''  'the labelled points shown in other 2 axes after completion'},...  buttondetails,...  'extraoptions','cancel',...      'defaultbutton',defaultbutton,...  'helpstring','help',...  'helpfcn','doc(''axes'');');
