TEdit does not like that you launch a dialog box from the OnEnter.
\nIn D1 you loose the caret and the selection highlighting in any case
\nIn D4 (not tested inD5) you have a goofing selection when arriving with a mouse click into the Edit :<\/p>\n
Drop 2 Edit. In the 2nd OnEnter add :
\n[code lang=”delphi”] showMessage(‘hello’);
\n[\/code]
\nLaunch your application and click in the middle of the 2nd Edit text.
\ntry to type something, and just move your mouse right or left …. STRANGE!<\/p>\n
Workaround:
\n Create a user message ( WM_EDITMSG = WM_USER + x), install an event handler which will fire the dialog box, and inside the OnEnter of your Edit do a PostMessage(WM_EDITMSG, 0, 0). The event handler firing the dialog will be executed after the completion of the focusing process of the TEdit.<\/p>\n
