Purpose: http://tcllib.sourceforge.net/BWman/ScrolledWindow.html is the documentation for BWidget's ScrolledWindow. Hopefully people will provide examples of using this widget.
Jos Decoster Some examples of using BWidget's ScrolledWindow. First, make a frame scrollable:
package require BWidget
# Make a frame scrollable
set sw [ScrolledWindow .sw]
pack $sw -fill both -expand true
set sf [ScrollableFrame $sw.sf]
$sw setwidget $sf
set uf [$sf getframe]
# Now fill the frame, resize the window to see the scrollbars in action
for { set i 0 } { $i < 20 } { incr i } {
for { set j 0 } { $j < 20 } { incr j } {
set nm [format "%s.b_%s_%s" $uf $i $j]
set b [button $nm -text "$i,$j"]
grid $b -row $i -column $j
}
}A text widget can be make scrollable like this:
package require BWidget
# Make a text-widget scrollable
set sw [ScrolledWindow .sw]
pack $sw -fill both -expand true
set txt [text $sw.txt -wrap none]
$sw setwidget $txt
# Insert some text, resize the window to see the scrollbars in action
$txt insert end {README: Tcl
This is the Tcl 8.4.3 source distribution.
Tcl/Tk is also available through NetCVS:
http://tcl.sourceforge.net/
You can get any source release of Tcl from the file distributions
link at the above URL.
}Listboxes (standard Tk or BWidget) can be make scrollable like this:
package require BWidget
# Make a tk-listbox scrollable
set swtk [ScrolledWindow .swtk]
pack $swtk -fill both -expand true
set lbtk [listbox $swtk.lbtk]
$swtk setwidget $lbtk
# Make a BWidget-listbox scrollable
set swbw [ScrolledWindow .swbw]
pack $swbw -fill both -expand true
set lbbw [ListBox $swbw.lbbw]
$swbw setwidget $lbbw
# Now fill the listbox, resize the window to see the scrollbars in action
for { set i 0 } { $i < 100 } { incr i } {
$lbtk insert end "This is item $i"
$lbbw insert $i $i -text "This is item $i"
}
