[Gambas-user] Release of gambas 1.9.18

[Benoit Minisini]

Hello world :-)

This release has two main changes:

1) The Editor control now supports custom syntax highlighting, and there is an 
example that shows that - I hope Steve Starr will be happy :-)

2) The Timer class is now implemented in the interpreter, and will be removed 
from any other component. You can create timers without the need of a GUI 
component now.

Here is the changelog:

About the Timer changes:

As Timer is implemented directly in the interpreter, the components 
developpers that had implemented them in their components must:

1) Remove the Timer class/control from their components

2) Calls GB.Hook() with GB_HOOK_TIMER, and implements a timer hook. This timer 
hook is called by the interpreter to create or remove timers.

3) Calls GB.RaiseTimer() each time a timer must raise its event.

Everything about that is explained on http://new.gambasdoc.org. Start to 
search at the http://new.gambasdoc.org/help/api/cat/timer page. And the gb.qt 
component source is the reference...

Good luck to Daniel & Laurent! :-)
