Change Log

• Version 0.1

Restrictions

• it is not recommended calling mouse and key input directly from events like OnClick, use Application.QueueAsyncCall instead
• do not forget to set back 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 Uses: 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- def's is 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
