Hi, all

I have problems with sending (emulation) keypresses to visual controls under Lazarus. Final solution must work under wince :). Hope Lazarus will help.

I try as wiki states:

  var K:TUTF8Char;
  ...
  K:=IntToStr(1); //simplified example
  grdBusket.IntfUtf8KeyPress( K, 1, false ); //sending key to grid control
  ...
  but with no luck.
  Help, guru :)

TControl.Intf* functions should only be used by the LCL interfaces.

Maybe if you explain what effect you want to achieve, some windows/wince devel can help.

IntfUtf8KeyPress will tell LCL that your control received a keypress message, and thus it will call your OnUTF8KeyPress handler, but it won't really emulate a key press on the control.

To do that I would try using SendMessageW to send a WM_CHAR (or some other message) to the control. docs here:

We have a partial implementation of SendMessage on LCLIntf, but I would bet it isn't capable of emulating key pressing everywhere.

The Windows version of SendMessage obviously only works for Windows and Windows CE.

Just curious... Other that writing a Virtual Keyboard application, what would you used 'emulating' keypresses for? Can't you simply call the appropriate method of the Grid?
