Detailed Description

an onscreen keyboard for touchscreen use. can be typed with the mouse too. takes some time, though.

it is somewhat simplified to its primary use of entering keywords.

an UI can call register(Component) on its top level container to recursively attach the keyboard to them. the keyboard will then automatically pop up on activation of these and hides after ENTER or ESC is pressed.

currently only registered components are able to receive keystrokes, as the focus is usually drawn away from them when typing to the OSK!

Member Data Documentation

Component org.hfbk.vis.visnode.VisKeyboard.focus [package]

if a visual key is hit, the client panel gets the focus, so some other field lost it. we reenforce the focus on need to send keystrokes to the last activated field.
