Hi,
I want to add a freehand draw in my app, with :
d = drawfreehand(app.UIAxes_1,'color','green');
But i have this error:
Error using images.roi.internal.ROI/parseInputs
ROI parent must be a valid Axes object.
Error in images.roi.Freehand
So how can i use drawfreehand in App Designer ?
Thanks a lot in advance.

At this time, the "drawfreehand" function only takes an 'axes' objects as an argument, not 'UIAxes', the type of axes that are used in App Designer. More information about the valid arguments for 'drawfreehand' can be found on this documentation page:

So is there a way to draw a roi on an image in the UIAxes in App designer?

It's kind of silently supported but you can programmatically (>=R2018b) add an axes to a uifigure and then draw* will work.
ax = axes('Parent', uifigure)
drawfreehand(ax)
