Avoid deleting of datatip when clicking on marker

When creating a datatip DT, it is deleted when I click on the marker without moving the DT.

Example:

figure

h = plot(rand(100,1));

DT = datatip(h,'DataIndex',22);

Now, clicking on the marker of the DT without moving this, will delete the DT when releasing the mouse-button. Important: I still want to be able to move the DT, it should just not be deleted when clicking on it without moving it.

Is there a simple way of preventing this from happening? I implemented a solution using listeners and undocumented stuff, but I was wondering if there is a simple solution that I'm just missing.

OK, here my solution which allows to move the DT, allows deleting the DT via contextmenu and restores it when being deleted by clicking on the DT. I don't quite like the fact that I cannot avoid the DT from being destroyed and have to restore it. Also, checking the stack to allow for deleting when being called by the contexmenu is a hack which might not work sometimes in the future. So, if anyone finds a more documented solution, I would be glad to hear it.

function DataTip_test

figure

h = plot(rand(100,1));

DT = datatip(h,'DataIndex',22);

addlistener(DT, 'ObjectBeingDestroyed',@RestoreDT);

% ==========================

function RestoreDT(varargin)

% Allow deleting when parent line is being deleted

if strcmp(h.BeingDeleted,'on'); return; end

% Allow deleting, if triggered by context menu

db = dbstack;

if strcmp(db(end).file,'createContextMenu.p'); return; end

% Otherwise, restore datatip

DT = datatip(h, 'DataIndex',DT.DataIndex);

addlistener(DT, 'ObjectBeingDestroyed',@RestoreDT);

end

end

Hi @Sebastian Hölz

Just set the 'PickableParts' = 'none'

DT = datatip(h,'DataIndex',22,'PickableParts','none');

My original question was not quite complete. I still want to be able to drag the DT to a different position. It should just not be deleted when I click on it without dragging it. Thus, the above answer does not solve my problem.

Sorry for not being precise enough, I have updated the original question to mention this.
