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 is likely a touch screen... Please let me know if there are any more effective ways.

Solution

  • 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.
