+# Demonstration of custom widget styles.
+#
+
+#
+# ~ BACKGROUND
+#
+# Checkbuttons in toolbars have a very different appearance 
+# than regular checkbuttons: there's no indicator, they
+# "pop up" when the mouse is over them, and they appear sunken
+# when selected.
+# 
+# Tk added partial support for toolbar-style buttons in 8.4 
+# with the "-overrelief" option, and TIP #82 added further
+# support with the "-offrelief" option.  So to get a toolbar-style 
+# checkbutton, you can configure it with:
+#
+# checkbutton .cb \
+#     -indicatoron false -selectcolor {} -relief flat -overrelief raised
+#
+# Behind the scenes, Tk has a lot of rather complicated logic
+# to implement this checkbutton style; see library/button.tcl,
+# generic/tkButton.c, and the platform-specific files unix/tkUnixButton.c
+# et al. for the full details.
+#
+# The tile widget set has a better way: custom styles.
+# Since the appearance is completely controlled by the theme engine,
+# we can define a new "Toolbutton" style and just use:
+#
+# checkbutton .cb -style Toolbutton
+#
+#
+# ~ DEMONSTRATION
+#
+# The tile built-in themes (default, "alt", windows, and XP) 
+# already include Toolbutton styles.  This script will add
+# them to the "step" and "blue" themes as a demonstration.
+#
+# (Note: Pushbuttons and radiobuttons can also use the "Toolbutton" 
+# style; see demo.tcl.)
+#
+
+style theme settings "step" {
+
+#
+# First, we use [style layout] to define what elements to
+# use and how they're arranged.  Toolbuttons are pretty
+# simple, consisting of a border, some internal padding,
+# and a label.  (See also the TScrollbar layout definition 
+# in demos/blue.tcl for a more complicated layout spec.)
+#
+    style layout Toolbutton {
+        Toolbutton.background
+        Toolbutton.border -children {
+            Toolbutton.padding -children {
+                Toolbutton.label
+            }
+        }
+    }
+
+# (Actually the above isn't strictly necessary, since the same layout 
+# is defined in the default theme; we could have inherited it 
+# instead.)
+#
+# Next, specify default values for element options.
+# For many options (like -background), the defaults
+# inherited from the parent style are sufficient.
+#
+    style default Toolbutton -width 0 -padding 1 -relief flat -borderwidth 2
+
+#
+# Finally, use [style map] to specify state-specific 
+# resource values.  We want a flat relief if the widget is
+# disabled, sunken if it's selected (on) or pressed, 
+# and raised when it's active (the mouse pointer is
+# over the widget).  Each state-value pair is checked
+# in order, and the first matching state takes precedence.
+#
+    style map Toolbutton -relief {
+	disabled 	flat
+    	selected	sunken  
+	pressed 	sunken  
+	active		raised
+    }
+}
+
+#
+# Now for the "blue" theme.  (Since the purpose of this
+# theme is to show what *can* be done, not necessarily what
+# *should* be done, the following makes some questionable
+# design decisions from an aesthetic standpoint.)
+#
+if {![catch {package require tile::theme::blue}]} {
+style theme settings "blue" {
+
+    #
+    # Default values:
+    #
+    style default Toolbutton \
+    	-width 0 -relief flat -borderwidth 2 \
+	-background #6699CC -foreground #000000 ;
+
+    #
+    # Configure state-specific values for -relief, as before:
+    #
+    style map Toolbutton -relief {
+	disabled 	flat
+    	selected	sunken  
+	pressed 	sunken  
+	active		raised
+    } 
+
+    #
+    # Adjust the -padding at the same time, to enhance
+    # the raised/sunken illusion:
+    #
+    style default Toolbutton -padding 4
+    style map Toolbutton -padding {
+	disabled	{4}
+	selected	{6 6 2 2}
+	pressed		{6 6 2 2}
+	active		{2 2 6 6}
+    }
+
+    #
+    # ... and change the foreground and background colors
+    # when the mouse cursor is over the widget:
+    #
+    style map Toolbutton -background {
+	active  	#008800
+    } -foreground {
+	active  	#FFFFFF
+    }
+}
+
+}
+
+#
+# ~ A final note:  
+#
+# TIP #82 also says: "When -indicatoron is off and the button itself
+# is on, the relief continues to be hard-coded to sunken. For symmetry,
+# we might consider adding another -onrelief option to cover this
+# case. But it is difficult to imagine ever wanting to change the
+# value of -onrelief so it has been omitted from this TIP.
+# If there as strong desire to have -onrelief, it can be added later."
+# ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

+# The Tile project aims to make sure that this never needs to happen.
