i'm facing difficulties capture mouse events tcustompanel component @ designtime. i've tried cmdesignhittest returning message.result := 1. works ok capturing when mouse enters component, fails sense when mouse leaves. i've tried messing component style, not work @ all. understand (from gather on web), after returning message.result := 1 on cmdesignhittest event, mouse events captured component, seems not work standard onmouseenter / onmouseleave events. wonder if can me working sample issue. thank in advance.
as test, try adding handler wm_nchittest message , make sure message.result getting set htclient when csdesigning flag enabled in componentstate property. saw online articles suggest htclient needed in order cm_designhittest work.
