MATLAB: Doubt with check boxes

cbir

hi i am deepthi….i am doing project in relevence feedback for cbir….i implemented the project… code is

function displayResults(filename, header)

figure('Position',[50 50 1300 690], 'MenuBar', 'none', 'Name', header, 'Resize', 'off', 'NumberTitle', 'off');

% Open 'filename' file… for reading… fid = fopen(filename);

i = 1; % Subplot index on the figure…

while 1 imagename = fgetl(fid); if ~ischar(imagename), break, end % Meaning: End of File…

    [x, map] = imread(imagename);
    subplot(2,5,i);
    subimage(x, map);
    i = i + 1;
end

fclose(fid);

result is it will display 10 images…. i dono how to display 1 checkbox(named relevant) under each image…plz help me i dono about position of checkbox to be display…i have to get feedback from the user and at the bottom in the middle i want to display 1 button(feedback)…plz help me….

MATLAB: How to quickly refer to various object handles in the GUI

Here is how I handle situations like these. I store all handles to a specific type in a structure with a fieldname corresponding to that type. This lets me index into the structure as needed, simplifying the code considerably. You could easily do a similar thing, even if you are using GUIDE. Just build the structure in the initialization code. Here is an example to show you what I mean:

function [] = GUI_mult_ax()
% Plot different plots according to slider location.
S.fh = figure('units','pixels',...
              'position',[300 300 860 300],...
              'menubar','none',...
              'name','GUI_mult_ax',...
              'numbertitle','off',...
              'resize','off');    
S.x = 0:.01:1;  % For plotting.         
S.ax(1) = axes('unit','pix',...
               'position',[20 80 260 210]);
S.ax(2) = axes('unit','pix',...
               'position',[300 80 260 210]); 
S.ax(3) = axes('unit','pix',...
               'position',[580 80 260 210]);     
plot(S.ax(1),S.x,S.x,'r');   
plot(S.ax(2),S.x,S.x.^2,'b');  
plot(S.ax(3),S.x,S.x.^3,'k'); 
set(S.ax,{'xtick','ytick'},{[],[]})
S.pb(1) = uicontrol('style','push',...
                    'unit','pix',...
                    'position',[20 10 260 30]);
S.pb(2) = uicontrol('style','push',...
                    'unit','pix',...
                    'position',[300 10 260 30]);
S.pb(3) = uicontrol('style','push',...
                    'unit','pix',...
                    'position',[580 10 260 30]);
set(S.pb,'String','Off','callback',{@sl_call,S})
function [] = sl_call(varargin)
% Callback for all pushbuttons.
% Note that I pass in the handle structure created above.  
% This could have been stored in GUIDATA or whatever.
[h,S] = varargin{[1,3]};  % calling handle and data structure.
N = find(S.pb==h);   % This lets us know which pb called.
if strcmp(get(S.ax(N),'visible'),'off')
    set(S.ax(N),'visible','On')
    set(S.pb(N),'string','Off')
else
    set(S.ax(N),'visible','Off')
    set(S.pb(N),'string','On')    
end

MATLAB: GUI control, fwrite, and file control

The error is occuring because you don't have a uiwait/uiresume in your GUI to pause execution. Thus the file opens, the gui opens, the file closes, you slide and get the error. To fix it, pause execution by intserting a uiwait() at the end of the GUI and a uiresume when you close it.

doc uiwait
doc uiresume
doc waitfor %another approach
