I get the following error message under scrolling the mouse wheel with zoom on:
Error while evaluating Figure WindowScrollWheelFcn
Cell contents reference from a non-cell array object.
Error in matlab.graphics.interaction.hitAxes>removeAxesInOffscreenContainers (line 63)
Error in matlab.graphics.interaction.hitAxes (line 21)
Error in zoom>locFindAxes (line 2502)
Error in zoom>localButtonWheelFcn (line 737)
Error using waitfor
Error while evaluating Figure WindowScrollWheelFcn
The problem is cause by the parent of the axes, in my case an uitab object. If the parent is a figure, it works fine. I defined a figure 'WindowScrollWheelFcn', but the debugger doesn't reach the function. The error comes before.
hfig = figure(...
'WindowScrollWheelFcn',{@figScroll});
Is there a way to get this working on axes within a uitab? Or how can I disable mouse wheel gestures with zoom = on? I use Matlab R2014b.
Thank you for your help!
EDIT - Here is a small example who reproduces the error:
hfig = figure(1);
% Tab group
tabgp = uitabgroup(...
'Parent',hfig,...
'Position',[0 0 1 1]);
Tab1 = uitab(...
'Parent',tabgp,...
'Title','Plot');
axh = axes(...
'Parent',Tab1,...
'Units','normalized',...
'Position',[0.1 0.1 0.8 0.8]);
% plot
plot(axh,1:100,randn(100,1))
zoom(hfig,'on')
uiwait(hfig);

I think that bug's fixed in R2015b.

Hello, is that just a guess or do you know it (can test it)? I have only the R2014b version. Thank you for your answer.

I actually don't use a mouse with a scroll wheel, but I just asked the guy who fixed the bug, and he said R2015b.

Hello Mike, thank you for your feedback. I have found a workaround for previous releases of r2015b.
% get handle
hZoom = zoom;
% define zoom callback for mouse gestures
set(hZoom,'ActionPostCallback',@MouseAction)
I define a callback for mouse clicks/scroll, who will be executed instead of gettting this error.

Dear Sebastian, I had the same problem. So the solution of this bug is just crazy. you need at least two axes in the same figure. Try this:
hfig = figure(1);
tabgp = uitabgroup(...
'Parent',hfig,...
'Position',[0 0 1 1]);
Tab1 = uitab(...
'Parent',tabgp,...
'Title','Plot');
axh2 = axes(...
'Parent',Tab1,...
'Units','normalized',...
'Position',[0.1 0.1 0.8 0.8],...
'visible','off');
axh = axes(...
'Parent',Tab1,...
'Units','normalized',...
'Position',[0.1 0.1 0.8 0.8]);
% plot
plot(axh,1:100,randn(100,1))
zoom(hfig,'on')
uiwait(hfig);
