Defines the different standard markers.

Constructor.

Destructor.

Returns the type identification of an object derived from a class inheriting SoBase. This is used for run-time type checking and 'downward' casting.

Usage example:

void foo(SoNode * node)
{
  if (node->getTypeId() == SoFile::getClassTypeId()) {
    SoFile * filenode = (SoFile *)node;  // safe downward cast, knows the type
  }
}

For application programmers wanting to extend the library with new nodes, engines, nodekits, draggers or others: this method needs to be overridden in all subclasses. This is typically done as part of setting up the full type system for extension classes, which is usually accomplished by using the pre-defined macros available through for instance Inventor/nodes/SoSubNode.h (SO_NODE_INIT_CLASS and SO_NODE_CONSTRUCTOR for node classes), Inventor/engines/SoSubEngine.h (for engine classes) and so on.

For more information on writing Coin extensions, see the class documentation of the toplevel superclasses for the various class groups.

Reimplemented from SoPointSet.

Returns a pointer to the class-wide field data storage object for this instance. If no fields are present, returns NULL.

Reimplemented from SoPointSet.

Action method for the SoGLRenderAction.

This is called during rendering traversals. Nodes influencing the rendering state in any way or who wants to throw geometry primitives at OpenGL overrides this method.

Reimplemented from SoPointSet.

Action method for the SoGetPrimitiveCountAction.

Calculates the number of triangle, line segment and point primitives for the node and adds these to the counters of the action.

Nodes influencing how geometry nodes calculates their primitive count also overrides this method to change the relevant state variables.

Reimplemented from SoPointSet.

Returns the number of defined markers.

Replace the bitmap for the marker at idx with the representation given by size dimensions with the bitmap data at bytes. isLSBFirst and isUpToDown indicates how the bitmap data is ordered. Does nothing if markerIndex is NONE.

Here's a complete usage example which demonstrates how to set up a user-specified marker from a char-map. Note that the 'multi-colored' pixmap data is converted to a monochrome bitmap before being passed to addMarker() because addMarker() supports only bitmaps.

const int WIDTH = 18;
const int HEIGHT = 19;
const int BYTEWIDTH = (WIDTH + 7) / 2;

const char coin_marker[WIDTH * HEIGHT + 1] = {
  ".+                "
  "+@.+              "
  " .@#.+            "
  " +$@##.+          "
  "  .%@&##.+        "
  "  +$@&&*##.+      "
  "   .%@&&*=##.+    "
  "   +$@&&&&=-##.+  "
  "    .%@&&&&&-;#&+ "
  "    +$@&&&&&&=#.  "
  "     .%@&&&&*#.   "
  "     +$@&&&&#.    "
  "      .%@&@%@#.   "
  "      +$%@%.$@#.  "
  "       .%%. .$@#. "
  "       +$.   .$>#."
  "        +     .$. "
  "               .  "
  "                  " };

int byteidx = 0;
unsigned char bitmapbytes[BYTEWIDTH * HEIGHT];
for (int h = 0; h < HEIGHT; h++) {
  unsigned char bits = 0;
  for (int w = 0; w < WIDTH; w++) {
    if (coin_marker[(h * WIDTH) + w] != ' ') { bits |= (0x80 >> (w % 8)); }
    if ((((w + 1) % 8) == 0) || (w == WIDTH - 1)) {
      bitmapbytes[byteidx++] = bits;
      bits = 0;
    }
  }
}

int MYAPP_ARROW_IDX = SoMarkerSet::getNumDefinedMarkers(); // add at end
SoMarkerSet::addMarker(MYAPP_ARROW_IDX, SbVec2s(WIDTH, HEIGHT),
                       bitmapbytes, FALSE, TRUE);

This will provide you with an index given by MYAPP_ARROW_IDX which can be used in SoMarkerSet::markerIndex to display the new marker.

Returns data for marker at idx in the size, bytes and isLSBFirst parameters.

If no marker is defined for given idx, or SoMarkerSet::markerIndex is NONE (not removable), FALSE is returned. If everything is OK, TRUE is returned.

Removes marker at idx.

If no marker is defined for given idx, or SoMarkerSet::markerIndex is NONE (not removable), FALSE is returned. If everything is OK, TRUE is returned.

Not supported in Coin. Should probably not have been part of the public Open Inventor API.

Contains the set of index markers to display, defaults to 0 (CROSS_5_5). The special value NONE renders nothing for that marker.
