[lazarus] MWEDIT TODO's needed

+ Handle can point to the name of the QT object.
+ Instead of passing the name of the LCL component to the QT engine, you
+ simply cast the Handle to a string or pchar and pass that to
+ the QT engine.

To be compatible we need the handle. While waiting till I could reach CVS
(some net problems between me and uu.net) and start to do some font stuff, I
started to look after the menu, which also involves owners and parents. Then
I came to the creation point of components.
It would be nice if it is handled in a way Delphi does. This is after a call
to HandleNeeded. I started to try to get this working for menus. In this a
Handle is important. The state of Handle <> 0 determens if the GTK/QT/WIN
object is created.
As I said earlier, the Handle should only be a reference (like is it in
win32) to the GTK/QT/WIN object and has no meaning in the LCL. It only has a
meaning in the interfaces (and there only Handle should be used to retrieve
the GTK/QT/WIN object). Something like
GTK:   Handle <--> fComponent
QT:    Handle <--> PChar(Name)
Win32: Handle <--> Handle

By using Handle (and in your interface PChar(Handle)) all the calls outside
the interface would be the same. As we see in parts needed for mwEdit now,
many handles are used.

Handles are a reference to your GTK/QT/WIN (windows) environment. But
components can't do anything without them.
