Ubuntu Manpage: XmMultiList — The Multi-column List widget

Provided by: libmotif-dev_2.3.8-3.1build1_amd64

NAME

       XmMultiList — The Multi-column List widget

SYNOPSIS

       #include <Xm/MultiList.h>

DESCRIPTION

This widget contains a multi-column list with headers along the top and a search area
along the bottom. The list has scrollbars along the right and bottom edges that allow
vertical and horizontal scrolling both by column and by pixel. The portion of the list
data that is currently visible can be altered by scrollbar actions, widget resource
setting and the redisplay of the list data after a string search has been successful. The
sorting of elements within a particular column is also supported. To sort the list by the
elements in a given column, select the column's title.

To search for a particular string in the list, type the string value to be searched for in
the list's associated text field and then press the "Find" pushbutton. The search for the
string begins in the currently selected row, after the location of the previously searched
for string, or at the first column and first row if there is no column selected. If the
string is not found in that row, then the search continues through all rows after and then
before, the currently selected row. If the string is found, the display of the list is
adjusted to make the string visible. If the string was not found, or if the string is
visible, the application will issue a warning beep.

Pointer button one allows the user to select a row or a column for sorting. The callbacks
on the doubleClickCallback list are called when the user double clicks pointer button one.
If the list data can contain a row pixmap to display at the extreme left of the row.

Classes
MultiList inherits behavior, resources, and traits from Core, Composite, Constraint, and
XmManager.

The class pointer is xmMultiListWidgetClass.

The class name is XmMultiList.

New Resources
The following table defines a set of widget resources used by the programmer to specify
data. The programmer can also set the resource values for the inherited classes to set
attributes for this widget. To reference a resource by name or by class in a .Xdefaults
file, remove the XmN or XmC prefix and use the remaining letters. To specify one of the
defined values for a resource in a .Xdefaults file, remove the Xm prefix and use the
remaining letters (in either lowercase or uppercase, but include any underscores between
words). The codes in the access column indicate if the given resource can be set at
creation time (C), set by using XtSetValues (S), retrieved by using XtGetValues (G), or is
not applicable (N/A).

Callback Routines

       All procedures on the MultiList's singleSelectionCallback  and  doubleClickCallback  lists
       will  have  a  pointer  to  a XmMultiListRowInfo structure passed to them in the call_data
       field. This structure is defined above.

       Note: if a single SelectionCallback is registered on an MultiList in extended_select_mode,
       the value of call_data is undefined.

                 void (callback)(Widget w, XtPointer client_data, XtPointer call_data)

       w         the MultiList widget

       client_data
                 the client data specified by the application

       call_data a pointer to an XmMultiListRowInfo structure corrsponding the the row selected

Sort Function

       typedef int (XmMultiListSortFunction) (short column, XmMultiRowInfo * row1, XmMultiRowInfo
       * row2);

       column    the column currently being sorted

       row1, row2
                 the two rows being compared. The return value must  be  an  integer  less  than,
                 equal  to,  or  greater  than 0, depending on whether the first argument is less
                 than, equal to, or greater than the second.
