I just want to build a pushbutton in a class defintion with a buttondown callback. But there is no reaction if I click the button.
If I change the 'buttondownfcn' to 'callback'. Then it will work. But I indeed need 'buttondownfcn' for my function.
Is this a Matlab bug or I missed something? I am using matlab 2011b.
Thanks guys.

function obj = testBtnCbk()
hfig = figure;
oTab.hBtn = uicontrol('style', 'pushbutton',...
'parent', hfig, ...

'foregroundcolor', [1 1 1], ...
'string', 'hello', ...
'Units', 'pixel', ...
'buttondownfcn', @obj.pshbtnDwnCbk, ...
'Position', [100 100 100 100]);
end
function pshbtnDwnCbk(obj, ~, ~)
msgbox('hello')
end
end
end
