What I could use is a midlet system that is completely backed by Java SE for example. Basically, for terminal displays and GUI components for the most part. The display manager could be actual widgets implemented in Swing, or I can write the rendering bits manually. One consideration is that an out of Swing renderer would be able to be used on any system which lacks a widget system. So the LCDUI code on existing systems, if there are access to widgets, will use those if possible. Although for a unified and initial experience, I can have the graphical system use a kind of generic framebuffer of sorts.

Since the LCDUI and the LUI code both have pretty much duplicated displays, I could potentially commonize these into a single set of interfaces perhaps.

07:49

With the terminal and framebuffer relying on a single class, a single instance of a provider can provide both. For example on Windows opening a terminal could make a command prompt window appear (or DOS prompt) while the framebuffer will make a window appear. One thing that will be needed is detecting and handling resizing of framebuffers and terminals accordingly. Then for the JavaSE interface, I can provide both a framebuffer and a terminal. Although both would use Swing, all of the code could easily be shared. Then I will need basic stuff such as setting titles for these displays which can be shared.

I could actually have a unified coordinate system using just X/Y values even in the terminal code that uses rows and columns.

07:55

Also, there can be common sharing between the meep-lui and midp-lcdui code since they essentially have duplicated Display although with slightly different functionality.

07:57

Well really, the LUI one has setText and the LCDUI has commands, orientation, and vibration.

08:03

One thing I need to determine however is how J2ME's MIDP 2 handled things when it comes to Displays. Well it just got the Display for the current MIDlet. So I suppose that the display system for MEEP and MIDP would be on top of some kind of base class. Although the only thing that needs to be commonized would be the service loader and capabilities since essentially they both rely on services to exist. So I just need to commonize the services.

09:53

A bunch of the stuff in LUI is copy and pasted from LCDUI, but only from the MIDP 3 variant.

12:35

It appears as if my basic bootstrap build system is not considering some dependencies.

13:10

One thing I would have to consider is if for the Framebuffer code, if I can reuse Image and Graphics. I would keep the framebuffer very simple with no actual graphics drawing code, it would be purely a pixel buffer for the most part.

17:54

Actually, I can provide virtualized interface and custom items in forms and/or displayables by using virtual controls and canvases. For example if setting a List Displayable is not possible then there can be a virtual one that is a List but one where it extends Canvas internally. Doing it at the base LCD UI code means that the extra work does not have to be handled by LCDUI implementations. Technically they could, for theming purposes, but it would not be required.

In their copy and paste, they never used MODEACTIVE and MODENORMAL.
