Detailed Description

The SoSelection class manages a list of selected nodes.

Inserting an SoSelection node in your scene graph enables you to let the user 'pick' with the left mousebutton to select/deselect objects below the SoSelection node.

Using an SoBoxHighlightRenderAction or an SoLineHighlightRenderAction to render scenegraphs containing SoSelection nodes provides a convenient way of providing visual feedback about the selections to the application user.

Beware that one common faulty assumption which is made about the node is that the scene will automatically be re-rendered whenever the user pick objects. This is not the case, the application programmer must himself schedule a redraw. A straightforward way to accomplish this is to SoNode::touch() the SoSelection node in the selection / deselection callback.

A 'skeleton' for basic use of SoSelection nodes is given below:

extern SoSeparator * make_scenegraph( void );
static SoSelection * selection = NULL;
// Callback function triggered for selection / deselection.
void made_selection( void * userdata, SoPath * path )
{


  (void)fprintf( stdout, "%sselected %s\n",


                 userdata == (void *)1L ? "" : "de",


                 path->getTail()->getTypeId().getName().getString() );


  selection->touch(); // to redraw
}
// *************************************************************************
// Print a quick instructions notice on stdout.
void show_instructions( void )
{


  (void)fprintf( stdout, "\nThis example program demonstrates the use of the SoSelection node type.\n" );


  (void)fprintf( stdout, "\nQuick instructions:\n\n" );


  (void)fprintf( stdout, "  * pick with left mouse button\n" );


  (void)fprintf( stdout, "  * hold SHIFT to select multiple objects\n" );


  (void)fprintf( stdout, "  * hit ESC to toggle back and forth to view mode\n" );


  (void)fprintf( stdout, "\n" );
}
// *************************************************************************
int main( int argc, char ** argv )
{


  QWidget * window = SoQt::init( argv[0] );


  show_instructions();


  selection = new SoSelection;


  selection->policy = SoSelection::SHIFT;


  selection->ref();


  selection->addChild( make_scenegraph() );


  selection->addSelectionCallback( made_selection, (void *)1L );


  selection->addDeselectionCallback( made_selection, (void *)0L );


  SoQtExaminerViewer * examinerviewer = new SoQtExaminerViewer( window );


  examinerviewer->setSceneGraph( selection );


  examinerviewer->setGLRenderAction( new SoBoxHighlightRenderAction );


  examinerviewer->setViewing( FALSE );


  examinerviewer->show();


  SoQt::show( window );


  SoQt::mainLoop();


  delete examinerviewer;


  selection->unref();


  return 0;
}

This node is not initialized in SoDB::init(), since it is part of the interaction kit 'add-on'. Before using this node, you should therefore call SoInteraction::init(). If you're using one of the standard GUI-toolkits (SoXt / SoQt / SoWin) SoInteraction::init() will be called for you from the So[Xt|Qt|Win]init() method and you don't have to worry about it.

With regard to using multiple SoSelection nodes at the same time in the same scene graph: this is possible, but it is not straightforward. The standard viewers provided by SoQt, SoWin, et al, will only snoop on one SoSelection node (part of the the legacy API from SGI's InventorXt), so selection changes on the others doesn't trigger redraws. You don't necessarily see what's happening in other words. You'll have to hook up manually and trigger redraws yourself.

Also be aware that when having multiple SoSelection nodes in the scene graph active at the same time, the SoHandleEventAction traversals that you intend for selection-change on one SoSelection node will also affect all the other SoSelection nodes in the scene -- usually delesecting everything below them since you will be clicking outside the selectable objects. You'll therefore also have to manually override that behaviour, if you want selection change on one SoSelection node to not affect the others.

Member Enumeration Documentation

enum SoSelection::Policy

Enum for different pick policies.

Enumerator

Only one object can be selected at any time. When the user picks a new object, the previous selection will be unselected. If the user picks on nothing, the current selection will be unselected.

Note that if a new selection matches one already present in the selection list, neither a deselect nor a select notification callback will be made about that selection path.

Picking an object toggles its selection state.
Same as SINGLE, but when shift key is pressed the selection policy will be changed to TOGGLE.

Constructor & Destructor Documentation

SoSelection::SoSelection (void)

Default constructor.

SoSelection::SoSelection (const int nChildren)

Constructor.

The argument should be the approximate number of children which is expected to be inserted below this node. The number need not be exact, as it is only used as a hint for better memory resource allocation.

SoSelection::~SoSelection () [protected], [virtual]

Destructor.

Member Function Documentation

SoType SoSelection::getTypeId (void) const [virtual]

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.

void SoSelection::select (const SoPath * path)

Adds path to the list of selected objects.

void SoSelection::select (SoNode * node)

void SoSelection::deselect (const SoPath * path)

Remove path from the list of selected objects.

void SoSelection::deselect (const int which)

Remove objects which from the list of selected objects.

void SoSelection::deselect (SoNode * node)

Remove node from the list of selected objects. The scene graph below the Selection node will be searched, and the path to node will be removed if found.

void SoSelection::toggle (const SoPath * path)

If path is not already selected, add path to the list of selected objects. Otherwise remove path from the list of selected objects.

void SoSelection::toggle (SoNode * node)

If node is not already selected, add path to the list of selected objects. Otherwise remove node from the list of selected objects.

SbBool SoSelection::isSelected (const SoPath * path) const

Return TRUE if path is in the list of selected objects.

SbBool SoSelection::isSelected (SoNode * node) const

Return TRUE if the path to node is in the list of selected objects.

void SoSelection::deselectAll (void)

Returns the index'th selected objects.

SoPath * SoSelection::operator[] (const int i) const

Operator for accessing selected objects.

void SoSelection::addSelectionCallback (SoSelectionPathCB * f, void * userData = NULL)

Adds a callback which will be called every time an object is selected.

See also

removeSelectionCallback()

void SoSelection::removeSelectionCallback (SoSelectionPathCB * f, void * userData = NULL)

Removes one of the selection callbacks.

See also

addSelectionCallback()

void SoSelection::addDeselectionCallback (SoSelectionPathCB * f, void * userData = NULL)

Adds a callback which will be called every time an object is deselected.

See also

removeDeselectionCallback()

void SoSelection::removeDeselectionCallback (SoSelectionPathCB * f, void * userData = NULL)

Removes one of the deselection callbacks.

See also

addDeselctionCallback()

void SoSelection::addStartCallback (SoSelectionClassCB * f, void * userData = NULL)

Adds a callback which will be invoked when the user start an interactive change to the list of selected objects.

This callback is useful for storing the old selection list for undo/redo functionality.

See also

addFinishCallback()

void SoSelection::removeStartCallback (SoSelectionClassCB * f, void * userData = NULL)

Removes f from the list of start callbacks.

See also

addStartCallback()

void SoSelection::addFinishCallback (SoSelectionClassCB * f, void * userData = NULL)

Adds a callback which will be invoked when the user has finished an interactive change to the list of selected objects.

See also

addStartCallback()

void SoSelection::removeFinishCallback (SoSelectionClassCB * f, void * userData = NULL)

Removes f from the list og finish callbacks.

See also

addFinishCallback()

void SoSelection::setPickFilterCallback (SoSelectionPickCB * f, void * userData = NULL, const SbBool callOnlyIfSelectable = TRUE)

Sets the pick filter callback. This callback will be called when a path is about to be added to or removed from the list of selected objects. The callback function should return a replacement path that should be used instead of the picked path. The returned path will be ref'ed, copied, and then unref'ed again by the SoSelection node.

If no callback is set (the default), the picked path will be used for selecting/deselecting.

Possible return values from the callback:

  • NULL: simulate that nothing was picked. This will clear the selection for the SINGLE policy. The handle event action will be halted.
  • A path: the path will be selected/deselected. The handle event action will be halted.
  • A path containing only the Selection node: as NULL, but action will not be halted.
  • An empty path or a path not containing the Selection node: the pick will be ignored.

if callOnlyIfSelectable is TRUE, the callback will only be called if the Selection node is in the picked path.

void SoSelection::setPickMatching (const SbBool pickmatchflag)

When pickmatchflag is TRUE (the default), the mouse button release pick must match the mouse button press pick before object is selected/deselected.

This flag should normally not be of interest to application programmers.

SbBool SoSelection::isPickMatching (void) const

Returns TRUE if pick matching is enabled.

See also

setPickMatching()

SbBool SoSelection::getPickMatching (void) const

Returns TRUE if pick matching is enabled.
