DXmSvnAutoScrollCheck(3X)DXmSvnAutoScrollCheck(3X)NAME
DXmSvnAutoScrollCheck - Controls whether the DxmSvnAutoScrollDisplay routine should be called.
SYNOPSIS
int DXmSvnAutoScrollCheck(
Widget widget,
int x,
int y );
PARAMETERS
The identifier (widget ID) of the SVN widget. An integer that represents the x location of the cursor relative to the upper-left corner of
the SVN window. An integer that represents the y location of the cursor relative to the upper-left corner of the SVN window.
DESCRIPTION
The DXmSvnAutoScrollCheck routine determines whether the cursor is currently in an area where automatic scrolling (initiated when the user
moves an entry outside the window) can occur. This routine returns True if the cursor is in such an area and if there are no entries dis-
played in that direction. The application should call the DXmSvnAutoScrollDisplay routine if this routine returns True.
Use this routine if your application controls the dragging operations (using the DXmSvnSetApplDragging routine).
RETURN VALUES
An integer that indicates whether the DxmSvnAutoScrollDisplay routine will be called, as follows: DxmSvnAutoScrollDisplay will not be
called. DxmSvnAutoScrollDisplay will be called.

DXmSvnGetEntryPosition(3X)DXmSvnGetEntryPosition(3X)NAME
DXmSvnGetEntryPosition - Retrieves (returns) the position of an entry in the display.
SYNOPSIS
void DXmSvnGetEntryPosition(
Widget widget,
int entry,
Boolean mode,
int *x,
int *y );
PARAMETERS
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.
DESCRIPTION
The DXmSvnGetEntryPosition routine allows an application to determine the position of entries. The routine interprets the x and y coordi-
nates 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.
