I want the red rectangle to turn green when I only “left-click” (not right-click or middle click) on it. What is the easiest solution?
hax = axes('XLim', [0 4], 'YLim', [0 4]);
r = rectangle('Position', [1 1 1 1], 'FaceColor', 'r');

function test
FigH = figure;
hax = axes('XLim', [0 4], 'YLim', [0 4]);
r = rectangle('Position', [1 1 1 1], 'FaceColor', 'r', ...
'ButtonDownFcn', {@RectClickCB, FigH});
function RectClickCB(RectH, EventData, FigH)
switch get(FigH, 'SelectionType')
case 'normal' % Left click
set(RectH, 'FaceColor', 'g');
case 'alt' % Right click
case 'extend' % Middle click
otherwise
...
end
