Hello.

I am writing a program, and in while in the process of desinging it, I got to thinking about how much RAM I would have to work with. I know the sl-c3100 (the model I have), comes with 64MB of RAM, but I'm unsure how much of that gets used up by the OS etc... Anyway, I went to system info and checked the memory tab, and I'm seeing that on my zaurus, 31.3MB is being used and 30.7MB is free.

I only have 2 programs, the dictionary and the notepad set to fast load, so I can't imagine why more than half of my memory is being used up. Is this about average for a sl-c3100 running the default japanese 1.02 ROM? Does the OS and all the background stuff use up HALF of the 64MB?

If you guys could let me know if my situation is normal, I would appreciate it.

Hello.

I'm working on a java app that I will be using on a sl-c3100.

The problem I have having is that I want my program to use all of the screen that is available at any given moment, but there doesn't seem to be a way to find out what *IS* available? I'm pretty sure that the j2me specification is basically the same as java 1.1.8, and the only way I am aware of for getting the screen size is:

Dimension d = Toolkit.getDefaultToolkit().getScreenSize();

and the problem with that is that it just gives you the absolute size (either 640 x 480, or 480x600), and doesn't take into account the task bar, or the virtual keyboard/kanji pad. This means that when my program launches, it is bigger than the space I have available. Additionally, even if I set it to take the height of the taskbar into account, opening the virtual keyboard covers part of the app.

Is there anyway to figure out how much screen is availble in java, on a zaurus? Also, is there any sort of event I can listen for to handle the case that the virtual keyboard gets opened (so I will know I need to resize my program)?

Thanks for any help you can provide.

Hello.

I bought a 3100 last year, and have happily been using it as an amazing tool for Japanese study since then. The main selling point for me has been the ability to have Japanese dictionaries that can be searched via handwriting (kanji) recognition.

Like I said, I have been extremely happy with the 3100 so far; however, its one main fault (for me) is its lack of Java support - the reason being that I would like to write a flashcard / study tool for the device, but don't want to have to go through the trouble of writing it in Qt (I have already done a lot of the work in Java, and setting up the development environment for Qt is a pain).

Anyhow, I have been looking around for a solution to my problem, and I'm wondering if pdaXrom is a possible match for my needs.

I have done some looking around for myself, but I would really appreciate it if one of the pdaXrom gurus would let me know if these functionalities would be possible on a 3100 / pdaXrom setup (Entries marked with an * are absolutely essential. Other entries are "nice, but not essential"):

1*. Maintains japanese input support, including handwriting recognition. (From what I have read on the forums, it seems like you can get uim up and running in pdaXrom, but I am wondering whether it includes some sort of handwriting support.)

2*. Java (at least 1.4) support.

3*. A dictionary program exists for it that I could install Jim Breen's jdic (edict) dictionary into.

4. That dictionary program could also be used to access the two Japanese dictionaries (koujien and the other)that are included with the 3100. (I know this might be impossible because I think they are encrypted...)

That's pretty much it. Basically, I just want a solution with which I have Japanese handwriting support, a japanese-english dictionary, and the ability to run some Java study programs that I write.

Thanks for your help,
joe

Hey guys,

I'm having a problem entering Japanese text in QT Designer 2.3. Here is an outline of what happened...

About a week ago I went ahead and burned the latest Mandriva 2006 cds, and installed Mandriva on my computer. I went ahead and set up Japanese support/input (making sure to use a utf-8 font), and everything worked fine - I could see/type in Japanese on the desktop (when I make a new folder, file, etc...), I could see/type in Japanese in Firefox, etc. I could even enter Japanese text when making forms in QT Designer. This is using SCIM/ANTHY, by the way.

I did, however, have a problem. When I installed Mandriva that time, I installed all the developement stuff with it, which included a newer version of gcc. The problem was that, as you all know, in order to do Zaurus QT developement, you need to have gcc 2.95 installed if you want to build (so you can test) for the x86 environment.

Anyway, since I wanted to try a new install anyway (There was a bunch of other stuff that I decided I didn't want installed), I went ahead and deleted/reinstalled Mandriva. I got everything setup again (including Japanese input/support with SCIM/ANTHY again), and everything seemed fine - I could use Japanese everywhere...

However, now I have installed the qtopia 1.5 sdk again, and I absolutely cannot use Japanese in QT Designer anymore. For example, if I create a new button on a form, and try entering some Japanese for the button's text, it comes out as "????". I looked at the font that is being used for the form/button, and it says it's using a Japanese font ("Sazanami"), but it just doesn't matter.

Does anyone have any idea what I am doing wrong? I KNOWI was able to use Japanese the first time. And now, well... I've tried everything to get it working again. I've reinstalled Mandriva multiple times - with Japanese as the only language; with all the development stuff included again; etc... Nothing works.

If you guys have any ideas, please try to help me out.
