Thread Subject:

Disable figure closing by clicking on the cross

Hi everyone!

In my gui interface I want user to be blocked from doing anything, until a dialog box is closed.
I've thought of using :
>>uiwait(dialog)

but if the user clicks on the cross to close the window, he can do everything!

Excuse me for my english :D

[I also want the computer to go on executing its function while the dialog box blocks the user]

Dear Alessandro,

> but if the user clicks on the cross to close the window, he can do everything!

Clicking on the cross calls the CloseRequestFcn of the figure. So just define it following your demands, e.g.:
  figure('CloseRequestFcn', 'disp(''Do not click me!'')');
To close the figure programmatically, you have to set the CloseRequestFcn to '' or the default 'closereq'. Otherwise the figure is immortal!

But blocking the user is not a friendly method and a nervous user will press Ctrl-C soon.

Kind regards, Jan

Most of MATLAB's dialog boxes have an option called 'modal' which does what you seem to want. Out of curiosity, what are you actually trying to do? Is this dialog box preventing the user from continuing to use the GUI while some process is running? Are you getting necessary data from the user, and they can't move on until they give the data?

Yes, exactly!
The problem is that uiwait(dialog) bloks every process execution!!

I find that setting the appropriate UICONTROL's enable property to 'off' or 'inactive' while the process is running, along with an appropriate indication to the user, is an effective way of dealing with this type of situation. Just don't forget to set the 'enable' property back to 'on' when the process is finished.

Try using the enableDisableFig utility on the File Exchange: http://www.mathworks.com/matlabcentral/fileexchange/15895-enabledisable-figure

It makes the entire figure disabled without blocking processing
