TEdit hint in OnKeyPress

Recommended Posts

Hello! I need to make hint appears in OnKeyPress event like in NumbersOnly-property (see attach). Because I use another input logic (not only numbers, but some special symbols too). I know that hint message is generated by Windows itself. What should I do?

good way (path) is verify the sources on Delphi for this components (teditnumber) and see like this event works

I know about TBalloonHint component, but I want to make system hint as I said. See attach again.

What you're searching for are called tooltips. Window with TOOLTIPS_CLASS class, TTM_* messages and so on.
