Hey,

I started with TWL and I like it very much, anyway I have some beginners questions:

1. There are inputMapDef actions like *selectAll *cut *copy *paste.
Is there a list in the docs somewhere? At first I didn't realise, that they have actual behaviour, just thought they where some arbitrary strings...

2. Why are some theme names starting with this dash, e. g. "-smiley" and "-defaults" and not "smiley" and "defaults", does it make any difference?

3. Is layout() called on every widget, and when? When do I have to overwrite it? Which positioning possibilities do I have, "only" setPosition() and setSize() ?

4. Is there an TWL IRC channel, I read it somewhere...

Thanks a lot in advance for your support!
Kind regards,

Stefan

Hello Stefan,

1) how actions are defined depends on each widget - for example here is the action mapping of EditField

2) this is purely a convention - I use the leading dash to indicate that this is not something final/useable (to assign to a theme) but more of an intermediate element - eg to allow it to be reused

3) layout() is called on every widget and it must only position it's own children, if your widget has no children then you don't need to override it. Instead of doing a manual layout you can use DialogLayout, BoxLayout, ColumnLayout or the new BorderLayout to handle layouts.

4) you can find me (and others using TWL) in #lwjgl on freenode.

Regards
Matthias

Thanks for the answers!

I have another beginners question: I can add Widgets to another Widget via add(Widget child) method.
What do I need a Container for then?

Is there any doc how the different layout widgets work?

Thanks again!

Every Widget has some doc Also check out the TWL-Examples project where ouy can find a lot of help.

It is true that every Widget can have children. But the basic Widget class does not do any kind o layout (the method is empty). There are a few layout widgets which just layout their children to some rules (Container, BoxLayout, BorderLayout, ColumnLayout, DialogLayout). But you are free to subclass Widget and perform your own layout by overriding the layout() method.
