LogCurve Object Class
Overview
The LogCurve object class provides a visual representation of a Log curve. An
extensive set of resources is available to customize the appearance of a
LogCurve object. The data used for a LogCurve object is specified using a one
dimensional array containing the sample values. A second array, the depth
array, can also be specified if the sample values are not evenly spaced in
depth. Points of a LogCurve graphic object can be edited. A portion of the
LogCurve can also be selected and edited independently.
Creation
A LogCurve object can be created as a child of a Track widget, a widget class
optimized to handle the display of LogCurve objects. It is also possible to
create LogCurve objects as children of other widget classes such as the Seismic
or Grid classes, and more generally, on top of any class derived from the
EditObject class. A LogCurve object is created in a similar fashion as is a
widget, using standard functions such as XtCreateWidget or using function
XintCreateLogCurve. LogCurve objects and other graphic objects should never
be managed.
Editing
LogCurve objects can be edited. Editing operations include the standard actions
defined in the Graphic class, such as select, move, size or shape. In addition,
specific actions are provided to add, delete and move the LogCurve object
points. Editing is enabled by registering the proper translation table to the
LogCurve object parent.
Built-in Resource Editor
The LogCurve object has a built-in resource editor panel that allows the
end-user to edit the object resources. It can be invoked by using public
function XintEditObjectManageResourceDialog.

Action ResourceDialog (defined by the EditObject class) is also available for
the enduser to interactively edit the object's resources.This action is
connected as follows in the default translation table:
Note that action ResourceDialog actually checks for a double click, so it will
only trigger on a double click of Button1.
You can disable the resource editor panel by setting Graphic resource
XmNresourceDialog to False when creating the object.
