Damn, call me, what you want, but i'm stuck and i cannot find a way out :/

Well i started with application with button, text field and a label. And i cannot fill my stuff with life. Standard way to double click on an item to move to code section, and adding some "basic" code for an event (like in c++builder or Visual Studio) doesn't work here.

How am i suppose to add some code to "on click" event, when dblclicking on item doesn't show(add) it?
