Detect if touch device

I'm writing a MIDlet using the Kuix UI toolkit, and I want to make changes to the toolkit depending on whether the current device is a touch screen device. (These changes include making buttons bigger, for easier tapping.)

Is there a way to detect whether the device has a touch screen using J2ME (MIDP 2)?

[edit] as a (crappy) workaround I check for the screen height instead. A screen width a height of higher than 240 开发者_开发知识库is likely a touch screen... Please let me know if there are any more effective ways.

try Canvas.hasPointerEvents() -- it seems to be an instance method. No idea why this isn't static.

Checks if the platform supports pointer press and release events.

in canvas this function will tell you whether you have touchDevice or not,

    public boolean isTouchDevice() {
            if (hasPointerEvents() && hasPointerMotionEvents())
                    return true;
            return false;
    }
