In Windows:
uses
Windows;
procedure TForm1.FormCreate(Sender: TObject);
const
ECM_FIRST = $1500;
EM_SETCUEBANNER = ECM_FIRST + 1;
begin
SendMessage(Edit1.Handle, EM_SETCUEBANNER, 0,
LParam(PWideChar(WideString('My placeholder on Windows';
end;
I implemented this feature in an old project that I maintain, LazSolutions,
and it was cross-platform.

I may be wrong, but I don't believe all LCL's backend toolkits support this, and probably why TEdit doesn't support it yet.

[Lazarus] Feature request/inquiry
Hi, I was wondering about the following: Many websites have a feature where, in a form that you must fill in, some explanatory text is shown in fields. This explanatory text is somewhat grayed in appearance, and disappears as soon as you start typing. Something like: (use fixed font to see this): +-+--+ | Name : | | +-+--+ I use a web toolkit called ExtJS, and it has a property 'emptyText'. This is the text that appears in the edit field when empty. We started using it extensively after we heard from our customers this is really valuable. (more so than a tooltip) Is there such a thing for Lazarus' TEdit and related controls ? if not, is it planned ?
