DXmSvnGetEntryPosition - Retrieves (returns) the position
of an entry in the display.
void DXmSvnGetEntryPosition(
Widget widget,
int entry,
Boolean mode,
int *x,
int *y );
The identifier (widget ID) of the SVN widget. An integer
that represents the number of the entry for which position
information is required. A Boolean value that, when True,
specifies that position information returned is relative
to the upper-left corner of the SVN window. When False,
the position information returned is internal SVN information
only (for column and outline mode) or indicates the
position of the entry in the entire tree (tree mode). A
pointer to the x position in the tree. A pointer to the y
position in the tree.
The DXmSvnGetEntryPosition routine allows an application
to determine the position of entries. The routine interprets
the x and y coordinates differently, depending on
the application's mode: Outline and Column mode
When the application is in outline or column mode
(the DXMSvnNdisplayMode resource has been set to
either DXMSvnKdisplayOutline or DXMSvnKdisplayColumn)
and mode for the DXmSvnGetEntryPosition routine
has been set to True, the x and y coordinates
indicate, in pixels, the distance of the displayed
entry from the upper-left corner of the SVN window.
However, if the specified entry is not visible in
the SVN window, the routine returns -1 (an invalid
value) for both the x and y coordinates, because
the SVN widget cannot determine the position of
such an entry when the application is in outline or
column mode.
When mode is False, the values returned for the x
and y coordinates are only meaningful internally to
the SVN widget. Tree mode
When the application is in tree mode (the DXMSvnNdisplayMode
resource is set to DXMSvnKdisplayTree)
and the DXMSvnNtreeStyle resource is set to
DXMSvnKuserDefinedTree (the application controls
the format), the x and y coordinates indicate, in
pixels, the distance of the displayed entry from
the upper-left corner of the SVN window, when mode
is True.
If the entry is not visible in the SVN window, the
mode is False. However, in tree mode, the returned
x and y coordinates indicate the position of the
entry in the entire tree, even though that position
extends beyond the limit of what can currently be
displayed in the SVN window.
Note that for position values to be valid, the SVN
widget must have been enabled prior to any changes
made to the contents of the display.
