This part is used to draw some information near the nodes. This information can be the one of a VisuNodeProperty or something else. When read from a VisuNodeProperty, just giving the name will produce the right output. In other cases a print routine must be given.
VisuExtension* initExtInfos (void);
Create the extension, it is called by V_Sim on startup and should not used elsewhere.
Returns : |
the newly created VisuExtension. |
typedef enum
{
DRAW_NEVER,
DRAW_SELECTED,
DRAW_ALWAYS
} VisuGlExtInfosDrawId;
This enum represents the possibilities for the information drawing.
typedef enum
{
EXT_DRAW_METH_NONE,
EXT_DRAW_METH_ID,
EXT_DRAW_METH_TYPE,
EXT_DRAW_METH_OTHER
} VisuGlExtInfosDrawMethod;
This enum represents the method for information drawing.
gboolean visu_glExt_infos_setOn (VisuData *data,gboolean status);
Change the status of the informations extension.
|
a VisuData object ; |
|
a boolean. |
Returns : |
TRUE if the calling routine should call visu_object_redraw().
|
void visu_glExt_infos_drawIds (VisuData *data,int *nodes);
Associate a informations extension to the given data. With this extension,
some the number of nodes will be drawn on them. Numbers can be drawn and
all nodes (set nodes to a NULL pointer), or to a restricted list of nodes
represented by their numbers. In this case, nodes can have whatever length
but must be terminated by a negative integer. This array is then owned by the
extension and should not be freed.
|
a VisuData object ; |
|
an integer list, terminated with a negative number. |
void visu_glExt_infos_drawElements (VisuData *data,int *nodes);
As visu_glExt_infos_drawIds(), but draw the names of elements instead of their
numbers.
|
a VisuData object ; |
|
an integer list, terminated with a negative number. |
void visu_glExt_infos_drawData (VisuData *data,VisuDataNode *dataNode,int *nodes);
As visu_glExt_infos_drawIds(), but draw some informations instead of their
numbers. The informations are defined by the dataNode argument.
|
a VisuData object ; |
|
a VisuDataNode object ; |
|
an integer list, terminated with a negative number ; |
void visu_glExt_infos_build (VisuData *dataObj);
Build the OpenGL list representing the informations associated to the given
dataObj. To associate some, use visu_glExt_infos_drawIds(), or visu_glExt_infos_drawElements()
or visu_glExt_infos_drawData().
|
a VisuData object. |
