  • Do not forget to reset the mouse button and key state after Down method with Up method.

Carbon

  • Pressing alpha chars is not supported.

Gtk1/2

  • Needs Xtst library.
  • ALT key pressing is not supported.

How to

With your project open:

  • Go to the Lazarus install directory -> components -> mouseandkeyinput.
  • There you will find: lazmouseandkeyinput.lpk.
  • Open and compile the .lpk.

In your unit.pas add in the Uses clause:

..., MouseAndKeyInput, LCLType;

To simulate press of F1 from a button:

procedure TForm1.HelpButtonClick(Sender: TObject);
begin
  KeyInput.Apply([ssCtrl]);
  KeyInput.Press(VK_F1);                // This will simulate press of F1 function key.
  KeyInput.Unapply([ssCtrl]); 
end;

VK- definitions are found here: http://lazarus-ccr.sourceforge.net/docs/lcl/lcltype/index-2.html

Mouse control:

  MouseInput.Click(mbLeft,[],300,300);   // Left click on X:=300 , Y:=300
  MouseInput.Click(mbRight,[],1365,2);   // Right click on X:=1365 , Y:=2
