List content of item in the combobox
I have a combo.cgi here. this is linux environment
What i am going to do is this combobox will list down all the flatfile name in this /u/test/cgi-bin/List directory.
after that, i wanted it to open the flatfile and display the content of the flatfile into another listbox or textarea in this page once the item is selected in the combobox.
Pls guide me here

print "Content-type: text/html\n\n";
print "<html><head>";
print "</head><body>";


Code:
@testList = `ls -1 /u/test/cgi-bin/List`;

NAME

       ttk::combobox - text field with popdown selection list

SYNOPSIS

       ttk::combobox pathName ?options?
_________________________________________________________________

DESCRIPTION

       A ttk::combobox combines a text field with a pop-down list of values; the user may select the value of the text field from among the values
       in the list.

STANDARD OPTIONS

       -class		     -cursor		  -takefocus
       -style

       See the ttk_widget manual entry for details on the standard options.

WIDGET-SPECIFIC OPTIONS
       Command-Line Name:-exportselection
       Database Name:  exportSelection
       Database Class: ExportSelection

	      Boolean value.  If set, the widget selection is linked to the X selection.

       Command-Line Name:-justify
       Database Name:  justify
       Database Class: Justify

	      Specifies how the text is aligned within the widget.  Must be one of left, center, or right.

       Command-Line Name:-height
       Database Name:  height
       Database Class: Height

	      Specifies the height of the pop-down listbox, in rows.

       Command-Line Name:-postcommand
       Database Name:  postCommand
       Database Class: PostCommand

	      A Tcl script to evaluate immediately before displaying the listbox.  The -postcommand script may specify the -values to display.

       Command-Line Name:-state
       Database Name:  state
       Database Class: State

	      One of normal, readonly, or disabled.  In the readonly state, the value may not be edited directly, and the user can only select one
	      of  the -values from the dropdown list.  In the normal state, the text field is directly editable.  In the disabled state, no inter-
	      action is possible.

       Command-Line Name:-textvariable
       Database Name:  textVariable
       Database Class: TextVariable

	      Specifies the name of a global variable whose value is linked to the widget value.  Whenever the variable changes value  the  widget
	      value is updated, and vice versa.

       Command-Line Name:-values
       Database Name:  values
       Database Class: Values

	      Specifies the list of values to display in the drop-down listbox.

       Command-Line Name:-width
       Database Name:  width
       Database Class: Width

	      Specifies an integer value indicating the desired width of the entry window, in average-size characters of the widget's font.

WIDGET COMMAND

       The following subcommands are possible for combobox widgets:

       pathName current ?newIndex?
	      If newIndex is supplied, sets the combobox value to the element at position newIndex in the list of -values.  Otherwise, returns the
	      index of the current value in the list of -values or -1 if the current value does not appear in the list.

       pathName get
	      Returns the current value of the combobox.

       pathName set value
	      Sets the value of the combobox to value.

       The   combobox	widget	 also	supports   the	 following   ttk::entry   widget   subcommands	 (see	ttk::entry(3tk)   for	 details):
       bbox		     delete		  icursor index 		insert		     selection xview The combobox widget also sup-
       ports  the  following  generic  ttk::widget  widget  subcommands  (see	ttk::widget(3tk)   for	 details):   cget		   config-
       ure	      identify instate		     state

VIRTUAL EVENTS

       The combobox widget generates a <<ComboboxSelected>> virtual event when the user selects an element from the list of values.  If the selec-
       tion action unposts the listbox, this event is delivered after the listbox is unposted.
