Hello,
I have a listbox with draggable items and I noticed that, when viewing the top of the list and initiating a drag operation, firstRow was always returning -1 instead of 0. This went unnoticed because the subsequent for loop adds 2 to the index (not sure why). However, this fails when I try to drag and drop the very last row of my listbox (since the for loop only searchs up to the second to last row).
I changed the firstRow call to:
const int firstRow = getRowContainingPosition (0, headerComponent->getHeight());
And the for loop to
for (int i = getNumRowsOnScreen() + 1/*2*/; --i >= 0;)
And this allowed me to have correct behavior, but I do not know if this is a correct fix for the problem (or if anyone else is seeing this same issue).
Submitted for the consideration of JUCEier programmers than myself.
