Dear All,
is there a difference between Dragable and Moveable ?
why Form is Moveable ? Why Group is Dragable ?

To my mind (I may be wrong), the main difference between the terms within Dyalog APL (as against common English usage) is what is causing/controlling the repositioning.

Draggable: The "user" (while holding down one of the mouse buttons) DRAGS an object by using a mouse to position the GUI object

Moveable: Whie a GUI object can be MOVED under program control. For example, an animation of ball bouncing around within a box.

I think the answer is that "moveable" is applied to forms (and subforms) because they are top-level objects, while "dragable" applies to everything else.

Moving a form around on the screen is arguablly somewhat different than dragging a button around on a form.

'Move" is also the term that windows uses on the system menu of a form, and the ability to move a form is mixed up with the existence this menu.
