Description

This function inquires information about a specified graphics list, or a graphic contained within the graphics list.

Unlike most other functions that modify a MIL object, you can call this function concurrently from multiple threads on the same MIL graphics list (GraListId) without using an M_MUTEX object, as long as all the other parameters of the concurrent calls do not also share data.

Note that this function reference has not been updated for a MIL system added during a MIL update. Refer to the MIL system's release note to see if there is complementary information.

Parameters

This function is not supported on the selected boards.

Parameters

GraListId

Specifies the identifier of the graphics list about which to inquire information. The graphics list must have been previously allocated on the required system using MgraAllocList().

LabelOrIndex

Specifies the graphic about which to inquire, or specifies to inquire about the graphics list itself. This parameter should be set to one of the following values:

For specifying the graphic or the graphics list
Value	Description
M_GRAPHIC_INDEX( MIL_INT Index )	Specifies the index of an existing graphic about which to inquire. (summarize) Specifies the index of an existing graphic about which to inquire. (more details...)
		Parameters
		Index Specifies the index. The index is from 0 (inclusive) to the total number of graphics in the list minus 1. You can get the number graphics in the list with M_NUMBER_OF_GRAPHICS. If the inquired value is not supported on the graphic specified, an error is generated.
M_GRAPHIC_LABEL( MIL_INT Label )	Specifies the label of an existing graphic about which to inquire. (summarize) Specifies the label of an existing graphic about which to inquire. (more details...)
		Parameters
		Label Specifies the label. The label must be greater than 0. You can get the label of the last graphic added to the list with M_LAST_LABEL. If the inquired value is not supported on the graphic specified, an error is generated.
M_LIST	Inquires information about the graphics list itself.

SubIndex

Specifies the index of the sub-element of the graphic about which to inquire. If this information is not required or supported, set this parameter to M_DEFAULT.

For specifying the index of a graphic's sub-element

Value

Description

M_DEFAULT

Specifies to inquire about the graphic itself (instead of just a sub-element).

0 <= Value <= M_NUMBER_OF_SUB_ELEMENTS

Specifies the index of the sub-element of the graphic about which to inquire. The following table lists all the graphics for which you can inquire information about their individual sub-elements and outlines how sub-indices are assigned for each of these.

Graphics types	Index of sub-element values
Dots (created using MgraDots()).	The indices, starting from 0, are assigned to each dot in order of creation.
A single line (created using MgraLine() or user-defined using MgraInteractive() set to M_GRAPHIC_TYPE_LINE).	0 is assigned to the specified start point, and 1 is assigned to the specified end point of the line.
Sets of finite length lines (created using MgraLines() with M_LINE_LIST).	The indices, starting from 0, are assigned to the specified start point and end point of each line, in order of creation. For example, the start point of the first line has an index of 0 and the end point has an index of 1, and the start point of the second line has an index of 2 and the end point has an index of 3.
Sets of infinite lines (created using MgraLines() with M_INFINITE_LINES).	The indices, starting from 0, are assigned to the first and second specified point of each line, in order of creation. For example, the first specified point of the first line has an index of 0 and its second specified point has an index of 1, and the first specified point of the second line has an index of 2 and its second specified point has an index of 3.
A polygon (created using MgraLines() with M_POLYGON or user-defined using MgraInteractive() set to M_GRAPHIC_TYPE_POLYGON).	The indices, starting from 0, are assigned to each polygon vertex in order of creation.
A polyline (created using MgraLines() with M_POLYLINE or user-defined using MgraInteractive() set to M_GRAPHIC_TYPE_POLYLINE).	The indices, starting from 0, are assigned to each polyline point in order of creation.

(summarize)

Specifies the index of the sub-element of the graphic about which to inquire.

(more details...)

InquireType

Specifies the setting to inquire.

See the Parameter associations section for possible values that can be specified.

UserVarPtr

Accepts the address of one of the following (see the Parameter associations section for specifics on which is expected):

MIL_DOUBLE
MIL_ID
MIL_INT
MIL_INT32
MIL_INT64

Specifies the address in which to write the requested information. Since the MgraInquireList() function also returns the requested information, you can set this parameter to M_NULL.

See the Parameter associations section for possible values that can be returned.

Parameter associations

The tables below list possible values for the InquireType parameter and possible values returned to the UserVarPtr parameter.

For inquiring about a setting of a graphics list itself

M_LAST_LABEL +		Inquires the label that was automatically assigned to the last graphic added to the list in the current thread. This label value will never change, even if the order of the graphics in the list changes.

This label can be used as a means of identifying the graphic independently from its index, which might change if a graphic is deleted from the list. You cannot retrieve the label value of the last added graphic if it has been deleted or moved to another graphics list. If a graphic was added to the list from a different thread, the value returned will be that of the last graphic added to the list from the current thread; it will not return the label value of graphics added from a separate thread. This can be problematic when using MgraInteractive() to add graphics to the list interactively, since the graphics might be added from a separate thread. In this case, use MgraGetHookInfo() with M_GRAPHIC_LABEL_VALUE.
