With a friend/coworker we work on a prototype of a GUI system
like QML.
QML is not native and visual aspect can't follow platform
specific style efficiently, but today GUI style changes often
and fast. Old Windows Widget style seems dying. Microsoft now
use Aero and Office don't looks close to old Widgets
applications. An other important point is that smallest devices
now support OpenGL
more and more.
We choose to do something like QML because it's a relatively to
implement, the user have to create it's own components and give
a fine control of GUI behavior.
http://en.wikipedia.org/wiki/QML
Techno we use :
- OpenGL 2.1 (to support older hardware)
- SDL2
- Lua for ui declaration (QML use a javascript engine, JIT
cause some issues on iOS for exemple, a move to D should be
great in a future)
- __traits to generate bindings
- D signals (we don't use thread for the moment)
Status of "DQuick" :
The major features actually missing in the script engine are
components and user defined properties to allow user to declare
it's own virtual types, without this it's not possible to
create a Button because it's not a base type.
Property binding just works fine.
For other part of DQuick a lot of objects are missing, like
State, Animation, Loader. Our item can't be loaded
asynchronously and for images it can be an issue.
Issues :
- Remote desktop doesn't seems work under Windows (due to
OpenGL? or bad driver?)
- Realtime resize doesn't works (investigation need to be done)
We may open our code when components will be implemented plus
the addition of a better demonstration. We are really far of a
production release and a schedule can't be done for the moment,
don't hope to much on it :-).
I forgot that we don't support text for the moment, but we'll use
FreeType library, but we already have some experiences with it.
