The Palm Pre already COMES with an on-screen keyboard. It works in portrait and landscape, in all apps, in all fields.

Press the "sym" key and a scrollable 5x5 keyboard pops up full of alternate characters.

+ _7 e V$ x1 H( v$ mAt the simplest level then, creating an on-screen keyboard requires editing the alternate characters table json, to add the "regular" charcters to it, and then when you want a keyboard, press SYM and poof, a keyboard. T- N' j! j: V5 j/ a/ t: U

At the next level, widget_charselector.js needs to be modified to not close the keyboard after each keypress.

Update: 8/04/09 I have been editing widget_charselector.js, and no changes have occurred, can be deleted, and still no changes occur, it does not control sym in the least bit -Joesmith |
