+# 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
+}
+
+### Class bindings.
