hFigBlur = blurFigure(hFig, state)

blurFigure(hFig) blurs figure hFig and prevents interaction with it. The only interaction possible is with user-created controls on the blurring panel (see below).

hFigBlur = blurFigure(hFig) returns the overlaid blurred figure pane. This is useful to present a progress bar or other GUI controls, for user interaction during the blur phase.

blurFigure(hFig,STATE) sets the blur status of figure hFig to STATE, where state is 'on','off',true or false (default='on'/true).

blurFigure(hFig,'on') or blurFigure(hFig,true) is the same as: blurFigure(hFig).

blurFigure(hFig,'off') or blurFigure(hFig,false) is the same as: close(hFigBlur).

blurFigure('demo') displays a simple demo of the blurring (see attached screenshot).

Input parameters: (all parameters are optional)

hFig - (default=gcf) Handle(s) of the modified figure(s). If component handle(s) is/are specified, then the containing figure(s) will be inferred and used.

state - (default='on'/true) blurring flag: 'on','off',true or false

hFigBlur = blurFigure(hFig); % blur hFig (alternative #1)
hFigBlur = blurFigure(hFig,true); % blur hFig (alternative #2)

hFigBlur = blurFigure(hFig,false); % un-blur hFig (alternative #1)
hFigBlur = blurFigure(hFig,'off'); % un-blur hFig (alternative #2)
close(hFigBlur); % un-blur hFig (alternative #3)
delete(hFigBlur); % un-blur hFig (alternative #4)

blurFigure('demo'); % blur demo with progress bar etc.

This code heavily relies on undocumented and unsupported Matlab functionality. It works on Matlab 7.9 (R2009b) and higher (up to R2013a), but use at your own risk!
