Name:	buttonPlacement
Class:	ButtonPlacement
Command-Line Switch:	-buttonplacement

Specifies the placement of the insertion and removal buttons relative to the scrolledlistbox widgetsn, bottom, or center. The default is bottom.

Name:	lhsLabelText
Class:	LabelText
Command-Line Switch:	-lhslabeltext

Specifies the text for the label of the lhs scrolledlistbox. The default is "Available".

Name:	rhsLabelText
Class:	LabelText
Command-Line Switch:	-rhslabeltext

Specifies the text for the label of the rhs scrolledlistbox. The default is "Available".

Name:	lhsButtonLabel
Class:	LabelText
Command-Line Switch:	-lhsbuttonlabel

Specifies the text for the button of the lhs scrolledlistbox. The default is "Insert >>".

Name:	rhsButtonLabel
Class:	LabelText
Command-Line Switch:	-rhsbuttonlabel

Specifies the text for the button of the rhs scrolledlistbox. The default is "<< Remove".

The disjointlistbox command creates a disjoint pair of listboxs similar to the OSF/Motif "Book" printing dialog of the "FrameMaker" program. It is implementation constists of a two Scrolledlistboxs, 2 buttons, and 2 labels.

The disjoint behavior of this widget exists between the interaction of the two Scrolledlistboxes with one another. That is, a given instance of a Disjointlistbox will never exist, without the aid of a hack magician, which has Scrolledlistbox widgets with items in common. That means the relationship between the two is maintained similar to that of disjoint sets.

Users may transfer items between the two Listbox widgets using the the two buttons.

Options exists which include the ability to configure the "items" displayed by the 2 Scrolledlistboxes and to control the placement of the insertion and removal buttons.

The disjointlistbox command creates a new Tcl command whose name is pathName. This command may be used to invoke various operations on the widget. It has the following general form: pathName option ?arg arg ...? Option and the args determine the exact behavior of the command. The following commands are possible for disjointlistbox widgets:

pathName cget option

Returns the current value of the configuration option given by option. Option may have any of the values accepted by the disjointlistbox command.

pathName configure ?option? ?value option value ...?

Query or modify the configuration options of the widget. If no option is specified, returns a list describing all of the available options for pathName (see Tk_ConfigureInfo for information on the format of this list). If option is specified with no value, then the command returns a list describing the one named option (this list will be identical to the corresponding sublist of the value returned if no option is specified). If one or more option-value pairs are specified, then the command modifies the given widget option(s) to have the given value(s); in this case the command returns an empty string. Option may have any of the values accepted by the disjointlistbox command.

pathName setlhs

Set the current contents of the left-most Scrolledlistbox with the input list of items. Removes all (if any) items from the right-most Scrolledlistbox which exist in the input list option to maintain the disjoint property between the two

pathName setrhs

Set the current contents of the right-most Scrolledlistbox with the input list of items. Removes all (if any) items from the left-most Scrolledlistbox which exist in the input list option to maintain the disjoint property between the two

pathName getlhs

Returns the current contents of the left-most Scrolledlistbox

pathName getrhs

Returns the current contents of the right-most Scrolledlistbox

pathName insertlhs

Add the input list of items to the current contents of the left-most Scrolledlistbox. Removes all (if any) items from the right-most Scrolledlistbox which exist in the input list option to maintain the disjoint property between the two

pathName insertrhs

Add the input list of items to the current contents of the right-most Scrolledlistbox. Removes all (if any) items from the left-most Scrolledlistbox which exist in the input list option to maintain the disjoint property between the two.
