Q Is there any way I can stop LClick from hiliting the cells when users scroll
the cursor outside the list's rView area? My program allows users to select
more than one item from a list and then DRAG these selected items to another
list and DROP them there. But I run into a problem with the LClick function
when I hold down my mouse and drag these items OUTSIDE the list's rview area.
This function still hilits other cells when I move my cursor up or down.
Orginally, I only selected 3 items, but now I have more than 3 items
highlighted because of the resulting action by LCLICK. I already looked at the
sample code ModalList: it has this problem too. A If you want to use LClick and not change the hilite of cells when the mouse leaves the rView of the list, the best way is to install an LClickLoop procedure and check where the mouse is at any given time. If the mouse is outside of your list's rect as in:
GetMouse(&localPt);
if (PtInRect(localPt, &(*list)->rView) == false) {
// we're out of the list, return false
return false;
}
else
return true;
return false to tell the List Manager that the current click should be aborted. It turns out that this is a nice way to start a drag as well, since you know that the mouse has left the rect. [May 01 1995] |
