# screen.display
|
|
#------------------------------------------------------------------------------
|
|
# Class that manages a dialog, which displays an arbitrary number of properties
|
|
# periodically updating the values. Property names are abbreviated to the
|
|
# shortest possible unique part.
|
|
#
|
|
# Example:
|
|
#
|
|
# var dpy = screen.display.new(20, 10); # x/y coordinate
|
|
# dpy.setcolor(1, 0, 1); # magenta (default: white)
|
|
# dpy.setfont("SANS_12B"); # see $FG_ROOT/gui/styles/*.xml
|
|
#
|
|
# dpy.add("/position/latitude-deg", "/position/longitude-deg");
|
|
# dpy.add(props.globals.getNode("/orientation").getChildren());
|
|
#
|
|
#
|
|
# The add() method takes one or more property paths or props.Nodes, or a vector
|
|
# containing those, or a hash with properties, or vectors with properties, etc.
|
|
# Internal "public" parameters may be set directly:
|
|
#
|
|
# dpy.interval = 0; # update every frame
|
|
# dpy.format = "%.3g"; # max. 3 digits fractional part
|
|
# dpy.redraw(); # pick up new settings
|
|
#
|
|
#
|
|
# The open() method should only be used to undo a close() call. In all other
|
|
# cases this is done implicitly. redraw() is automatically called by an add(),
|
|
# but can be used to let the dialog pick up new settings of internal variables.
|
|
#
|
|
#
|
|
# Methods add(), setfont() and setcolor() can be appended to the new()
|
|
# constructor (-> show big yellow frame rate counter in upper right corner):
|
|
#
|
|
# screen.display.new(-15, -5, 0).setfont("TIMES_24").setcolor(1, 0.9, 0).add("/sim/frame-rate");
