1.11 Multitouch operation
1.11.1 Multitouch function
Overview
When multitouch displays are introduced, it is necessary to adjust operation to the extended
functionality of the display. The rigid positioning of softkeys, for example, is eliminated and
replaced or supplemented by free positioning of buttons. Due to the diversity of design options
for buttons, it no longer makes sense to use just one control for programming whose
appearance is based exclusively on the design specifications of the operating software. Toggle
controls, which only know two states, can be replaced by switches, for example, that show the
respective state by means of an icon and react to tap or flick gestures.
Displays graphics can be given the capability of reacting to pan gestures. The imagebox control
has been extended for this purpose.
Note
Graphics displayed in the paint tag still do not react to gestures.
Outside of the controls provided by the parser, finger gestures can be processed in the script,
thus providing the option, for example, of offering new navigation strategies in the dialogs.
Finger gestures could be used for zooming in to/out of dialog contents.
The Easy XML parser supports the following finger gestures:
Finger gestures

● Select window
● Select object (e.g. NC set)
● Activate entry field
– Enter or overwrite value
– Tap again to change the value
Flick vertically with one finger
● Scroll in lists (e.g. programs, tools, zero points)
● Scroll in files (e.g. NC program)
