TEdit with enhanced keyboard support?

[Edwin Yip 154]

Is there an enhanced TEdit (single-line edit, not multi-line editing such as TSynEdit) with enhanced keyboard support?

By enhanced keyboard support I mean for example, Ctrl+Backspace to delete a word, and so on.

Isn't a single line edit part of synedit?

To be specific, which component?

Why don't you use the native Win32 TEdit but just enable CTRL+BACKSPACE?

 

Call  

 

    SHAutoComplete(WindowHandle, SHACF_AUTOAPPEND_FORCE_OFF or SHACF_AUTOSUGGEST_FORCE_OFF);

 

in an overridden CreateWnd. Use an interposer, or some other mechanism to get this code to run.

Did a full text search of `SHAutoComplete` into my repositories and I couldn't believe I already have (but forgotten) a TEdit-derived control which already uses this trick, the code looks like:

[UIPermission(SecurityAction.LinkDemand, Window=UIPermissionWindow.AllWindows)]
procedure TEyEdit.CreateWnd;
begin
  inherited;

  //enable ctrl+backspace: http://stackoverflow.com/a/10305706/133516
  SHAutoComplete(Self.Handle, SHACF_AUTOAPPEND_FORCE_OFF or SHACF_AUTOSUGGEST_FORCE_OFF)
end;

But followed this HeidiSQL discussion this approach seems to be too issue-introducing...

And it seems that the HeidiSQL author went for another approach. Will check it later.

I use SHAutoComplete and don't have any issues.
