delphi - How can I create my own custom Hint for a specific control? -

i need create custom hint window (with it's own color , layout) specific command (not entire application)

the hint text not connected specific hint property control.

as suggested wrote handler cm_hintshow (this worked if command has showhint=true):

procedure tmycontrol.cmhintshow(var message: tmessage); begin form1.caption := 'x'; // here display own hint window // inherited; end;

but now, how know when/where hide when hint times out? neither cm_hintshow or cm_hintshowpause gives me info.

in cm_hintshow message handler, can cast lparam value phintinfo pointer , customize fields needed. instance, alter background color, set thintinfo.hintcolor field. alter layout of hint, can derive new class thintwindow , assign class type thintinfo.hintwindowclass field.

let vcl manage hint you, including showing , hiding it.
