Detailed Description

The ComponentBase class is derived from Group and DisplayFrame. It is capable of containing objects as well as drawing them. It is used for encapsulating object geometry and behavior. The behavior is defined when this object is derived.

Constructor & Destructor Documentation

ComponentBase ( int  generateInstance = 0)

Constructor

Parameters
generateInstanceIf true generates a new unique instance name
virtual ~ComponentBase ( )
virtual

Cleans up the object and destructs it. Don't call "delete yourComponent", instead call yourComponent->Destroy(). If this is an RSO, it will be completely destroyed, including the DLL.

Member Function Documentation

bool AbsolutePlacement ( ) const
inline

Gets the value for Absolute Placement. If true, the component will be left in the generated location. Otherwise it will be moved based on its extents

virtual void AbsolutePlacement ( bool  val)
virtual

Sets the value for Absolute Placement. This affects what happens durring the call to CreateObjects(). If true, the component will be left in the generated location. Otherwise it will be moved based on its extents

Reimplemented in GlsRSOWrapper.

virtual void CalcDrawMatrix ( )
protectedvirtual

Overridden from base class This adds the _editorTransformMatrix to the DCS. You will need to call CalcDrawMatrix whenever the _editorTransformMatrix changes.

Reimplemented from DisplayObject.

virtual void CalculateMatrices ( const OpenGLMatrices newMatrices)
protectedvirtual

Applies the _drawMatrix to the modelMatrix. If necessary derived classes can save other matrices.

Parameters
newMatricesA set of matrices passed down to this object from its parent.

Reimplemented from DisplayObject.

static bool CheckLiveVersion ( ComponentBase comp,
const GlsBuiltVersionInfo callingVersion = GlsBuiltVersionInfo() 
)
static

Returns true if version checks ok, false if there MIGHT be a problem. The consequences of version mismatches depend on the methods that will be called on the object. This will emit warnings to stdout.

Parameters
compRSO
callingVersionLeave this as the default and it will use the calling function's version information.
Returns
true If version is considered OK.
virtual void ClearDragAndFocus ( )
virtual

Call this before deleting objects which may be being kept by the drag or focus objects.

Reimplemented from DisplayFrame.

virtual DisplayObject* CloneObject ( bool  generateNames = false)
virtual

Copy+Create operation in one method. In derived classes, this method will create a new instance of the derived class and then copy the object into the new instance. The cut,copy,paste and undo operations use this method.

Parameters
generateNamesWhether or not to generate new names for cloned objects
Returns
A new object, identical to the original, except for the instance name

Reimplemented from Group.

Reimplemented in GlsRSOWrapper, and SplashDisplay.

virtual void CopyGeometry ( DisplayObject src)
virtual

Copies the geometry information from one object to another. Used by the undo mechanism to allow user to undo a geometry change.

Parameters
srcThe object to copy geometry from

Reimplemented from Group.

Reimplemented in GlsRSOWrapper.

virtual void CopyProperties ( DisplayObject src)
virtual

Copies the attributes except for geometry attributes from one object to another. Used by the undo mechanism to undo most attribute change operations.

Parameters
srcThe object to copy properties from

Reimplemented from Group.

Reimplemented in GlsRSOWrapper.

static ComponentBase* CreateLiveComponent ( const char *  fileName = NULL,
const char *  className = NULL,
bool  performCreate = true,
const GlsBuiltVersionInfo callingVersion = GlsBuiltVersionInfo() 
)
static

Create RSO static This will load the specified DLL and try to create the specified class. It will return the ComponentBase* on success, and NULL on failure. Internally, this uses a LiveComponentAccessor. If more control is needed, it is recommended to create a LiveComponentAccessor.

Parameters
fileNameThe name of the DLL
classNameThe class name to create. If NULL, the default class will be created.
performCreateIf true, CreateObjects() will be called, otherwise it will not.
callingVersion
Returns
NULL on failure.
virtual void CreateObjects ( )
virtual

In derived classes this creates all the geometry for the component

Reimplemented in GlsRSOWrapper, and SplashDisplay.

virtual void DeleteAllChildren ( )
virtual

Overriden to avoid children getting deleted until object deletion.

Reimplemented from Group.

virtual void Draw ( )
virtual

Draws this object and all its contained objects in the current OpenGL pipeline. This can be overloaded to perform any special effects. If PreDraw and Draw are needed, call DisplayFrame::Draw()

Reimplemented from Group.

Reimplemented in GlsRSOWrapper.

virtual DisplayObject* FindByNameSameFrame ( const char *  name)
virtual

Finds a pointer to the display object in the group, using the object's instance name as a key. Because this is a component, it will always return NULL.

Parameters
nameInstance name of the object to find
Returns
A pointer to the object if it is in the group, otherwise NULL

Reimplemented from Group.

virtual InterfaceListType* GetCppInterfaceDescription ( InterfaceListType addToThisList = NULL)
virtual

Get the details of the Cpp Interface The actual interface is exposed in compiled code.

Parameters
addToThisListA list to add to and then return. Creates a new one if NULL.
Returns
A templated list. The caller must call the corresponding free method to safely free the memory.

Reimplemented from DisplayFrame.

Reimplemented in GlsRSOWrapper, and SplashDisplay.

virtual void GetCppInterfaceDescriptionFree ( InterfaceListType array)
virtual

Frees the memory allocated by a previous GetCppInterfaceDescription call

Parameters
arrayPointer to memory allocated by GetCppInterfaceDescription

Reimplemented from DisplayFrame.

void NotifyAttributeChanged ( const AttributeName name)
overridevirtual

overrides DisplayObject::NotifyAttributeChanged

Reimplemented from DisplayFrame.

virtual void Parent ( DisplayFrame par)
virtual

Sets the DisplayFrame for this object. It does not set the specified parent for all the children. Instead, it sets all the children's parent to 'this'. And saves the argument 'par' in _parentDisplayFrame. This allows special traversals, which traverse out of the ComponentBase to the ComponentBase's parent.

Parameters
parThe parent which will be saved in _parentDisplayFrame

ParentDisplayFrame

Reimplemented from Group.

DisplayFrame* ParentDisplayFrame ( ) const
inline

Gets the value of the DisplayFrame containing this component

Returns
the value of the DisplayFrame containing this component. Returns NULL if there is no parent DisplayFrame
void ParentDisplayFrame ( DisplayFrame val)
inline

Sets the parent DisplayFrame for this object. This is normally only set by a call to Parent().

Parameters
valThe new val for _parentDisplayFrame

virtual DisplayObject* Pick3D ( const Vector winLoc,
const Vector logicalCoords,
float  scale,
const Vector directionVector,
Vector collisionWinLoc,
const OpenGLMatrices drawnMatrices 
)
virtual

Attempts to pick an object in 3D and accounting for dynamic rotations and translations of this object or parent objects. It also looks at the pickable status and attempts to return the "Best" pick if that is what is desired.

Note: This method will pick objects in the scene based on a pick ray starting at winLoc and pointing into the screen. It will not pick objects behind the depth specified by winLoc.z. Typically winLoc.z should be set to 0 to ensure that the pick ray starts at near clip plane.

Parameters
winLocDevice coordinates for the mouse click. Z value should be set to 0 to ensure pick ray starts at near clip plane.
logicalCoordsThe start of the pick ray in logical coordinates. Should be calculated from the winLoc using this->WindowToLogical(winLoc, logicalCoords, &directionVector).
scaleCurrent window scale. Affects picking radius of outlines. Initial value should typically be 1.0.
directionVectorThe direction of the pick ray in logical coordinates. Should be calculated from the winLoc using this->WindowToLogical(winLoc, logicalCoords, &directionVector).
collisionWinLocReturns where the pick vector intersects the object that is hit in device coordinates.
drawnMatricesThe matrices used to draw the object, including matrices set by parents that may have dynamically rotated, translated or scaled this object. Initial value should typically be a default OpenGLMatrices() object.
Returns
The object that was hit, or NULL if no object hit

virtual void PreDraw ( const OpenGLMatrices current,
Culler culler 
)
virtual

Traverses the hierarchy calculating the _modelMatrix, _projMatrix, _viewMatrix as needed.

Parameters
currentCurrent matrices inherited from parent
cullerObject that possibly marks this object for culling

virtual DistiAttributeBase& Resource ( const char *  name)
virtual

Gets a reference to the specified attribute for reading and writing. This reference can be streamed into and out of variables. This can access different levels of objects. For example: The DisplayFrame: Resource("ComponentHeaderFile") >> someStdString; An object in the DisplayFrame: Resource("SomeObject.Visible") << someBool; An object in a Component in this DisplayFrame: Resource("SomeComponentObject.SomeObject.Visible") >> someBool;

Reimplemented from DisplayFrame.

virtual void Rotate ( const Vector orig,
float  angle,
const Vector axis 
)
virtual

Rotates the object (around the specified axis) by the angle indicated, at the point specified. Recalculates the vertex data.

Parameters
origThe point to rotate around
angleThe angle to rotate by, in degrees
axisThe arbitrary axis to rotate the object around

Reimplemented from Group.

virtual void Scale ( float  px,
float  py,
float  pz,
Vertex anchor,
int  handleBar = 0 
)
virtual

Scales the object, either the handleBar, or the Anchor is used to translate the object, not both. Anchor takes presidence, if it is set HandleBar is ignored. The footprint is different from the 2D scale so the compiler can destinguish the two.

Parameters
pxValue of the percentage of scale in x-axis
pyValue of the percentage of scale in y-axis
pzValue of the percentage of scale in z-axis
anchorAnchor from which to scale object relative to
handleBarVertex that is being dragged

Reimplemented from DisplayObject.

virtual void SetAvailableAttributes ( unsigned int  value)
virtual

Specifies which attributes are available for the object. Currently the available attributes cannot be changed after they have been set. (Only the first call has an effect.)

Parameters
valueA bitfield specifying which types of attributes to make available.
