Rollover Regions, using State Files (CSV)
In the previous section, “Using Excel to Create Interactive Signs”, you learned that you
can create touchable (clickable) areas on the screen using elo (elor) and eloc keywords in
the EVENTS row of a CSV file. You can then use these regions like buttons to playback
content. Any touch region can be setup as a rollover region. Rollover regions allow you
to create more dynamic and interactive displays that accept mouse and touch input. A
rollover region has an ON and an OFF image. This allows your display to not only
respond to clicks or touch input, but also to the movement of the cursor. Whenever the
mouse cursor is within that region the ON image is displayed and the rest of the time the
OFF image is displayed. This allows buttons to highlight as the mouse cursor moves over
them.
Rollover Events
Use either of the following keywords in the events row to setup a rollover region:
Relor – you define a rectangular rollover region using this format:
o relor:x:y:width:height:enable_rollover:on_bitmap:off_bitmap:x_origin:y_
origin
o x:y - represents the starting position, where 0,0 is in the upper left
o width, height: width and height of the touch area in pixels
o enable_rollover: 1 to enable rollovers, 0 to disable rollovers
o on_bitmap: bitmap image name. Bitmap displayed when the mouse is
within the defined region
o off_bitmap: bitmap image name. Bitmap displayed when the mouse is not
within the defined region.
o x_origin,y_origin: rollover origin - the starting coordinates for the
rollover image. Set to -1, -1 to keep the default origin (same as the touch
area).
Reloc – you define a circular rollover region using this format:
o reloc:x:y:radius:enable_rollover:on_bitmap:off_bitmap:x_origin:y_origin
o x, y: center of the touch area
o radius: radius of the touch area in pixels
o enable_rollover: 1 to enable rollovers, 0 to disable rollovers
o on_bitmap: bitmap image name. Bitmap displayed when the mouse is
within the defined region
o off_bitmap: bitmap image name. Bitmap displayed when the mouse is not
within the defined region.
o x_origin,y_origin: rollover origin - the coordinates for the center of the
rollover image. Set to -1, -1 to keep the default origin (same as the touch
area).
