|

The touch-keyboard component presents a virtual keyboard on screen and emits
|
||||
input events when the user touches the virtual keys. It requires a GUI service,
|
||||
a "fonts" file-system session, and an event session.
|
||||
|
||||
By default, the keyboard is positioned at the top-left corner of the screen
|
||||
with the smallest possible size, given the used font. Those defaults can be
|
||||
the overridden by the configuration as follows.
|
||||
|
||||
! <config min_width="720" min_height="360" xpos="10" ypos="10"/>
|
||||
|
||||
The layout of the virtual keyboard is defined by a ROM module requested via
|
||||
the label "layout". An example can be found at
|
||||
_recipes/raw/touch_keyboard/touch_keyboard_layout.config_.
