delphi - Why doesn't TApplicationEvents.OnIdle get called? -

-

in app have main form button. clicking button, form (not auto-created in dpr) created , displayed; on form, placed tapplicationevents component , defined onidle event handler. event handler doesn't called! may depend because derived second form not tform other class, tchartbasicform (by means of vfi)? thank replies. massimo.

hooking application's idle event can lead lot of debugging woes , other maintenance headaches, on form other main form. realize may not answer specific question (which hard @ point given vagueness), sure can't accomplish you're trying ttimer or tthread instead?
