# Tix Demostration Program
#
# This sample program is structured in such a way so that it can be
# executed from the Tix demo program "widget": it must have a
# procedure called "RunSample". It should also have the "if" statment
# at the end of this file so that it can be run as a standalone
# program using tixwish.
# This file demonstrates how to use the TixTree widget to display
# hierachical data (A hypothetical DOS disk drive).
#
proc RunSample {w} {
# We create the frame and the ScrolledHList widget
# at the top of the dialog box
#
frame $w.top -relief raised -bd 1
# Create a TixTree widget to display the hypothetical DOS disk drive
#
#
tixTree $w.top.a -options {
separator "\\"
}
pack $w.top.a -expand yes -fill both -padx 10 -pady 10 -side left
set tree $w.top.a
set hlist [$w.top.a subwidget hlist]
# STEP (1) Add the directories into the TixTree widget (using the
# hlist subwidget)
set directories {
C:
C:\\Dos
C:\\Windows
C:\\Windows\\System
}
foreach d $directories {
set text [lindex [split $d \\] end]
$hlist add $d -itemtype imagetext \
-text $text -image [tix getimage folder]
}
# STEP (2) Use the "autosetmode" method of TixTree to indicate
# which entries can be opened or closed. The
# "autosetmode" command will call the "setmode" method
# to set the mode of each entry to the following:
#
# "open" : the entry has some children and the children are
# currently visible
# "close": the entry has some children and the children are
# currently INvisible
# "none": the entry does not have children.
#
# If you don't like the "autosetmode" method, you can always call
# "setmode" yourself, but that takes more work.
$tree autosetmode
# Use a ButtonBox to hold the buttons.
#
tixButtonBox $w.box -orientation horizontal
$w.box add ok -text Ok -underline 0 -command "destroy $w" \
-width 6
$w.box add cancel -text Cancel -underline 0 -command "destroy $w" \
-width 6
pack $w.box -side bottom -fill x
pack $w.top -side top -fill both -expand yes
}
# This "if" statement makes it possible to run this script file inside or
# outside of the main demo program "widget".
