progressbar

Progressbar with an abort button.

Description

This zip file contain 3 files:
    progressbar.m - the progress bar
    gui_active.m - polling function to be used in the runnig application (optional)
    gauge_abort_icon.mat - the icon on the button (optional button)

Directions:
    place 3 files in the same folder, and let MATLAB "know" it's path.
    you can create as many progressbars as you want,
    and update each of them using a unique handle.

    if a progress bar is closed using the "X" button on the upper-right
    corner of the progressbar, the function will create it again
    with it's same state, see example below (use copy-paste)
    
% progressbar - shows a progress bar dialog based on the function "waitbar"
%
% Format: handle = progressbar( handle,increment [,string,titlestr] )
%
% Input: handle - handle to current progress bar, [] for a new one
% increment - a fraction (0..1) to increment by.
% (-1) signals the function to remove the handle from
% the persistant list and close the progressbar
% string - a string to be replaced in the progress bar (optional)
% titlestr - a title for the dialog box (optional)
%
% Output: handle - a graphic handle of the dialog box
%
%
% NOTE: this function uses a persistant list of handles and thier values.
% therefore, to delete a progressbar, please call the function with:
% progressbar( handle,-1 );
%
% an "abort" button is formed inside the progressbar, if the calling process
% uses the persistent function "gui_active". when the "abort" button is pressed,
% the Callback function "gui_active" changes it's value to zero, which enables
% the application to interactively stop execution
%
% Example: gui_active(1); % will add an abort button
% h = progressbar( [],0,'my test' );
% max_count = 1e+3;
% for idx = 1:max_count
% fprintf( '%d\n',idx )';
% h = progressbar( h,1/max_count );
% if ~gui_active
% break;
% end
% end
% progressbar( h,-1 );

This is real good...All though I havent used it to its full potential.

Excellent. very simple to use.

[chris p]

easy to use, does the job perfectly!
thanks ohad

[Stephen Pickett]

Super easy to use. Quick and to the point

[Alexandre KOZLOV]

Simple to use but:
- only relative changes (i.e. no possibility to set absolute value, or reset bar);
- no way to change "Please Wait" message - I'm in France :-)
- strange abort mechanism;
I'd try to make an old good class with all properties accessible by getters/setters, including flags "show abort button" and "abort button was pressed".

Why not use the standard waitbar???

stop=false;
h = waitbar(0.0,'Please wait...','CreateCancelBtn','stop=true; delete(h); clear h');
set(h,'Name','optional window name');
for i=1:100
waitbar(i/100,h,['Update ' num2str(i)]);
if stop break; end
% do stuff
end
if exist('h') delete(h); end

Thanks for the waitbar suggestion -- it does exactly what I want.

The major difference between this function & waitbar is the abort functionality.

[Genaro Longoria]

Really good post

easy and just to the point.

[Peter Schuck]

works great, simple to use.

If you use following code, then you can see the estimated process time in bar..( 'mod' is for saving the total process time)..

tic
for i=1:yourprocess
        if mod(i,100)==0
        totaltime = int32(toc*yourprocess/i);
        string = sprintf('Trace # %d/%d, Time = %d sec', i,... not, totaltime);
        waitbar(i/yourprocess,h,['' string ]);
% ...
% your process....
% ...
end

not bad, but for 50,000 calculations workbar slows progress down by a factor of 2. Better than waitbar (a factor of 5) but still...
