Rewrite the Python program of Fig. 11.2. Create a multiple-selection list of colors. Al- low the user to select one or more colors and copy them to a ScrolledText component.

What will be an ideal response?

```
# Creating a multiple selection list.

from Tkinter import *
import Pmw

class ChoiceBox( Frame ):
"""Demonstrate multiple-selection lists"""

def __init__( self, listItems ):
"""Create multiple-selection list, Button and
ScrolledText"""

Frame.__init__( self )
Pmw.initialise()
self.pack( expand = YES, fill = BOTH )
self.master.title( "Select colors" )

# create a multiple-selection scrolled list box
self.listBox = Pmw.ScrolledListBox( self, items =
listItems, listbox_height = 5, vscrollmode = "static",
listbox_selectmode = MULTIPLE )
self.listBox.pack( side = LEFT, expand = YES, fill = BOTH,
padx = 5, pady = 5 )

self.copyButton = Button( self, text = "Copy >>>",
command = self.addColor )
self.copyButton.pack( side = LEFT, padx = 5, pady = 5 )

self.chosen = Pmw.ScrolledText( self, text_height = 6,
text_width = 20 )
self.chosen.pack( side = LEFT, expand = YES, fill = BOTH,
padx = 5, pady = 5 )

def addColor( self ):
"""Insert each selected item into ScrolledText"""

self.chosen.clear() # clear contents of chosen
selected = self.listBox.getcurselection()

if selected:

for item in selected:
self.chosen.insert( END, item + "\n" )

def main():
colorNames = ( "cyan", "green", "grey", "magenta",
"orange", "pink", "red", "white", "yellow" )
ChoiceBox( colorNames ).mainloop()

if __name__ == "__main__":
main()
