2.3 Viewer Control
procedure
Sets the starting slide for the talk to the most recently created
slide. If this function is used multiple times, the last use overrides
the earlier uses.
procedure
(enable-click-advance! on?) → void?
on? : any/c
Enables or disables slide advance as a result of a mouse click.
procedure
(set-use-background-frame! on?) → void?
on? : any/c
Enables or disables the creation of a background frame, which is
typically useful only when make-slide-inset is used are
active. The last enable/disable before the first slide registration
takes effect once and for all.
procedure
(set-page-numbers-visible! on?) → void?
on? : any/c
Determines whether slide numbers are initially visible in the viewer.
parameter
(current-page-number-font font) → void? font : (is-a?/c font%)
Parameter that determines the font used to draw the page number (if
visible).
parameter
(current-page-number-color) → (or/c string? (is-a?/c color%))
(current-page-number-color color) → void? color : (or/c string? (is-a?/c color%))
Parameter that determines the color used to draw the page number (if
visible).
Parameter that controls the precise text
that appears to indicate the page numbers (if visible). The
input to the function is the default string and the slide
number, and the result is what is drawn in the bottom right
corner. The default parameter value just returns its first
argument.
procedure
(set-spotlight-style! [ #:size size #:color color]) → void? size : (or/c #f (>=/c 0)) = #f color : (or/c #f string? (is-a?/c color%)) = #f
Adjusts the size and color of the “spotlight,” which can be enabled
in Slideshow as an alternative to the mouse. Note that the color
normally should have alpha value less than 1 (to make it partially
transparent). If size or color is #f, the
corresponding setting is unchanged.
