Hello,
I've recently been developing a GUI, which worked fine until Matlab crashed while running an unrelated code. A section of my code which allows a user to draw a ROI no longer works and reports an error with my impoly call (worked perfectly before Matlab crashed):
function cb(src,evt)
handles = guidata(src); %# import the data from the object
images=handles.images;
start = handles.view_slice;
last = handles.slices;
imshow(images(:,:,start),[])
h=impoly;
position = getPosition(h);
The error I now get is:
Error using hittest
Invalid object handle
Error in imshared.ipthittest (line 33)
h = hittest(hFigure, currentPoint);
Error in findLowestManagedObject (line 14)
hit_obj =
imshared.ipthittest(hFigure,buttonMotionEvent.currentPoint);
Error in iptPointerManager>createPointerManager/updatePointer
(line 334)
overMe =
findLowestManagedObject(hFigure,mouseMotionEvent);
Error in
iptPointerManager>createPointerManager/enablePointerManager (line
259)
updatePointer(figHandle, evt);
Error in iptPointerManager (line 72)
pointerManager.API.enable();
Error in manageInteractivePlacement (line 76)
iptPointerManager(h_fig,'Enable');
Error in impoly>impolyAPI (line 245)
placement_aborted =
manageInteractivePlacement(h_axes,h_group,@placePolygon,@buttonUpPlacement);
Error in impoly (line 97)
[h_group,draw_api] = impolyAPI(varargin{:});
Error in volume_scan>cb (line 288)
h=impoly;
Error while evaluating uitoggletool OnCallback
Apart from this not working, there is other weirdness including text stuck in a table on GUIDE (which I cannot remove) and a checkbox text which keeps defaulting to the 3rd option
Anybody got any ideas? Is there a crash file somewhere that needs to be reset/removed? I'm using 2012b.
Thanks, Jim
