+# Demonstration of custom classes.
+#
+# The Ttk button doesn't have built-in support for autorepeat.
+# Instead of adding -repeatdelay and -repeatinterval options,
+# and all the extra binding scripts required to deal with them,
+# we create a custom widget class for autorepeating buttons.
+#
+# Usage:
+#	ttk::button .b -class Repeater [... other options ...]
+#
+# TODO:
+#	Use system settings for repeat interval and initial delay.
+#
+# Notes:
+#	Repeater buttons work more like scrollbar arrows than
+#	Tk repeating buttons: they fire once immediately when
+#	first pressed, and $State(delay) specifies the initial
+#	interval before the button starts autorepeating.
+#
+
+namespace eval ttk::Repeater {
+    variable State
+    set State(timer) 	{}	;# [after] id of repeat script
+    set State(interval)	100	;# interval between repetitions
+    set State(delay)	300	;# delay after initial invocation
+}
