That's a nice GDI demo Peter and a good start on O2 library. Do you have any interest in SDL?

A library for SDL 1.2 is already done. Unfortunately is it very slow.

I need a good keyboard handler for SDL 1.2 as Android SDL doesn't support UNICODE. I'm doing a hack with a C toupper() to shift my alpha keys but I need to handle shifted keys like the single quote and number keys for symbols. Do you have anything that might work you would be willing to share?

Thanks for the reply. I'll keep looking.  :-\

What I'm looking for is something more like this.

Code: [Select]

if (ev.key.keysym.mod & KMOD_SHIFT) ch += 0x10;

ch is the non-unicode ev.key.keysym.sym value. My hope is that I can just add/subtract from the SDL given value to create a shifted or control modified key value. I'm trying to create something so I don't have to define a big CASE statement of possible shifted keys that toupper isn't taking care of.

I got it working expanding on the existing SWITCH/CASE structure for keyboard processing.

Thanks Peter for making an attempt to help.

I have attached a beta release of Brandy BASIC V for Android. You need to enable off market apps in settings and use adb to install Brandy on your device. I've included some Brandy BASIC V examples you can run off your sdcard. I also included the Ubuntu 64 bit version Brandy BASIC V which will need at least SDL 1.2 runtime installed. Let me know if you run into any issues.


** Install **

1. enable off market apps in settings.
2. adb install brandy.apk
3. copy Brandy examples to your sdcard

LOAD|RUN "/sdcard/brandy/graphdemo"

Remember Brandy (BBC BASIC) likes upper case commands.

Update I was able to get RTB (Return to BASIC) working on Android as well. You can downloaded the Android and Ubuntu 64 bit versions of RTB from the www.AllBASIC.info/forum if your interested.
