Hello all!
I patch edje to get working dragable objects like progressbars.
this done by event handling and passing to dragable (mouse_down,
mouse_up, mouse_move).
you should add section like next one
===
dragable {
events: "progress_bar_drag";
}
===
into "part" section of object on that you make action.
example in 2nd attached file.
i hope this will be useful in eclair volume and progress bar (i tested both)
thanks for attention.
