Questionnaire.m

I wrote a small questionnaire (exemplary m-file attached) and after we updated the Matlab from 2012b to 2015b the content of this questionnaire (text, radio buttons...) disappered / is empty. No buttons or text are visible .

The code:

hFig = figure('Visible','off', 'Menu','none', 'Name','SF12', 'Resize','on',... 
'units','normalized','outerposition', [0 0 1 1], 'Color', [1 1 1]);
uicontrol('Style','text','HandleVisibility','off','BackgroundColor', [1 1 0],... 
'String','Headline-Text',... 
'Position',[0.34 0.91 0.8 0.06],'Units','Normalized','HorizontalAlignment','left','FontSize',20,'FontName','Georgia')
%%Question 1 
hBtnGrp1 = uibuttongroup('Position',[0 0.75 0.495 0.07], 'Units','Normalized','BackgroundColor', [1 1 1]);
uicontrol('Style','text','Parent',hBtnGrp1, 'HandleVisibility','off','BackgroundColor', [1 1 1],...

在 MATLAB Online 中打开

Starting in R2014b, the parsing of the property/value pairs in the input arguments got pickier. Your code has lots of instances of this pattern:

'Position',[0.70 0.1 0.1 0.05], 'Units','Normalized', ...

Since the properties are now parsed strictly in left-to-right order, this will do exactly what it says. That is, it will set the Position property to [.7 .1 .1 .05] in the current units (which is pixels), and then it will set the Units property to normalized. The result is a tiny uicontrol that you can't see.

Before the graphics objects became real MATLAB Objects, they had a lot of special code to catch things like this that didn't make sense and quietly fix them, but there wasn't a place to stick that code in the new system.

You'll want to switch the order of your properties around like so:

'Units','Normalized', 'Position',[0.70 0.1 0.1 0.05], ...
