In Image Processing Toolbox, there are some functions which provides draggable object such as imrect and impoly etc.
For details, please refer the following documentation:
Also, this feature can be implemented using a combination of the Figure Properties and the graphic object properties. The figure properties to be used are:
The property of the graphic object to be used is:
The following example implements drag and drop functionality for a text box that is displayed on a Figure Window. This example function is also attached as a MATLAB-file:
function drag_drop
dragging = [];
orPos = [];
f = figure('WindowButtonUpFcn',@dropObject,'units','normalized','WindowButtonMotionFcn',@moveObject);
a = annotation('textbox','position',[0.2 0.2 0.2 0.2],'String','Hello','ButtonDownFcn',@dragObject);
function dragObject(hObject,eventdata)
dragging = hObject;
orPos = get(gcf,'CurrentPoint');
function dropObject(hObject,eventdata)
if ~isempty(dragging)
newPos = get(gcf,'CurrentPoint');
posDiff = newPos - orPos;
set(dragging,'Position',get(dragging,'Position') + [posDiff(1:2) 0 0]);
dragging = [];
function moveObject(hObject,eventdata)
if ~isempty(dragging)
newPos = get(gcf,'CurrentPoint');
posDiff = newPos - orPos;
orPos = newPos;
set(dragging,'Position',get(dragging,'Position') + [posDiff(1:2) 0 0]);
