I am running the drawnow
statement from a callback function within a MATLAB GUI to update the state of a button. At the beginning of the callback (which has high runtime) I alter the properties of the button and force an update with drawnow
. While updateing properly, the button remains rendered 'pushed down' instead of 'disabled'. After the callback is finished, the button is updated again and now rendered 'disabled'.
Take following minmal (not) working example:
function simple_example()
h = figure();
% add a button, give it some properties and a callback
uicontrol(h,...
'Style','pushbutton',...
'String','I am enabled',...
'Units','normalized',...
'Position',[0.5 0.5 0.4 0.4],...
'Callback',@btn_callback);
end
function btn_callback(hObject, ~)
set(hObject,'Enable','off');
set(hObject,'String','I am disabled');
drawnow;
pause(3);
end
Is there a way to change this behavior and have the button appear disabled while the callback is still executing?
