Description Ariel Constenla-Haile 2014-05-06 12:23:58 UTC 
With drop-down list boxes and combo boxes there is no way to get notified that the drop-down floating window is about to be opened.

Assume you have a drop-down list box that requires a lot of processing to get its content filled, you may want to fill it on-demand, when the drop-down is about to be activated.

Internally this is possible, as there is a VCLEVENT_DROPDOWN_PRE_OPEN (the other related event, VCLEVENT_DROPDOWN_OPEN, can be worked around by messing with the current accessibility support).
