How to set visible off in pushbutton after clicking.

After clicking play button then it will disappear.

function [] = main ()
figure('name','CROSSWORD PUZZLE','MenuBar','none','Color',[.7,.78,1],'units','normalized','outerposition',[0 0 .5 .8]')
Title='CROSSWORD';
a=1;
for x=20:30:260
    tagn=strcat('TBox',num2str(a));
    uicontrol('Style','edit','position',[x, 530, 30, 30],'String',Title(a),'FontSize',20,'Tag',tagn)
    a=a+1;
end
TitleB='PUZZLE';
a=1;
for x=80:30:230
    tagn=strcat('TBox1',num2str(a));
    uicontrol('Style','edit','position',[x, 500, 30, 30],'String',TitleB(a),'FontSize',20,'Tag',tagn)
    a=a+1;
end
S.pb = uicontrol('Style','pushbutton','Position',[500 350 60 30],'String','PLAY');
set(S.pb,'callback',{@game,S})
S.ob = uicontrol('Style','pushbutton','Position',[500 300 60 30],'String','OPTION');
set(S.ob,'callback',{@set,S})

function [] = game(varargin)

for x=20:30:620
    for y=420:-30:30   
         uicontrol('Style','edit','position',[x y 30 30],'FontSize',20)
    end
end

Ariel - you've assigned the following callback to the PLAY button

 function [] = game(varargin)

with a variable list of input arguments, varargin. I see also that when you set the callback, you pass an additional parameter, S, which is a structure that has the handles to the graphics objects. This seems to be similar to what GUIDE would do when it creates a callback with the third parameter being the handles structure. What this means, is that your callback could then be written as

 function [] = game(hObject, eventdata, handles)

where hObject is the handle to the play button graphics object and eventdata an empty matrix. So if you wish to set the visible flag for this button when you press it, you could do the following

 function [] = game(hObject, eventdata, handles)

 set(hObject,'Visible','off');

 % etc.

Note that the S is not like the usual handles structure (from GUIDE) since you don't (yet) have a mechanism to pass an updated it version of it each time the callback fires. So you could remove it and just assign and set the callback as

 set(S.pb,'callback',@game)

with

 function game(hObject, eventdata)

Thank you Sir., I also want to hide the OPTION pushbutton too. How?
