Description
The routine
PA_DragAndDrop
can be called when
PA_AreaEvent
returns
eAE_MouseDown
. It initiates a drag-drop operation. Pass the horizontal coordinate of the mouse in
startX
and its vertical coordinate in
startY
(be sure to use global coordinates, you may need to use
LocalToGlobal
on Macintosh or
ClientToScreen
under Windows to convert the local coordinates of the click returned by
PA_GetClick
to global coordinates needed for this drag and drop operation). Pass in
customRect
the rectangle that 4D will draw during the drag operation if you set
customRect
to 1. If
customRect
is set to 0, the dragging rectangle will be the size of the external area.
NOTE
The routines "Drag and Drop" are internal to 4th Dimension. The developer cannot use them with other applications.
