Detailed Description

Abstract definition of a 2D element to be displayed in an Overlay.

Remarks:
This class abstracts all the details of a 2D element which will appear in an overlay. In fact, not all OverlayElement instances can be directly added to an Overlay, only those which are OverlayContainer instances (a subclass of this class). OverlayContainer objects can contain any OverlayElement however. This is just to enforce some level of grouping on widgets.
OverlayElements should be managed using OverlayManager. This class is responsible for instantiating / deleting elements, and also for accepting new types of element from plugins etc.
Note that positions / dimensions of 2D screen elements are expressed as parametric values (0.0 - 1.0) because this makes them resolution-independent. However, most screen resolutions have an aspect ratio of 1.3333:1 (width : height) so note that in physical pixels 0.5 is wider than it is tall, so a 0.5x0.5 panel will not be square on the screen (but it will take up exactly half the screen in both dimensions).
Because this class is designed to be extensible, it subclasses from StringInterface so its parameters can be set in a generic way.

Constructor & Destructor Documentation

Ogre::OverlayElement::OverlayElement ( const String name  ) 

Constructor: do not call direct, use OverlayManager::createElement.

virtual Ogre::OverlayElement::~OverlayElement (  )  [virtual]


Member Function Documentation

virtual void Ogre::OverlayElement::updatePositionGeometry ( void   )  [protected, pure virtual]

Internal method which is triggered when the positions of the element get updated, meaning the element should be rebuilding it's mesh positions.

Abstract since subclasses must implement this.

Implemented in Ogre::BorderPanelOverlayElement, Ogre::PanelOverlayElement, and Ogre::TextAreaOverlayElement.

virtual void Ogre::OverlayElement::updateTextureGeometry ( void   )  [protected, pure virtual]

Internal method which is triggered when the UVs of the element get updated, meaning the element should be rebuilding it's mesh UVs.

Abstract since subclasses must implement this.

Implemented in Ogre::BorderPanelOverlayElement, Ogre::PanelOverlayElement, and Ogre::TextAreaOverlayElement.

virtual void Ogre::OverlayElement::addBaseParameters ( void   )  [protected, virtual]

Internal method for setting up the basic parameter definitions for a subclass.

Remarks:
Because StringInterface holds a dictionary of parameters per class, subclasses need to call this to ask the base class to add it's parameters to their dictionary as well. Can't do this in the constructor because that runs in a non-virtual context.
The subclass must have called it's own createParamDictionary before calling this method.

Gets the name of the material this element uses.

virtual void Ogre::OverlayElement::setMaterialName ( const String matName  )  [virtual]

Sets the name of the material this element will use.

Remarks:
Different elements will use different materials. One constant about them all though is that a Material used for a OverlayElement must have it's depth checking set to 'off', which means it always gets rendered on top. OGRE will set this flag for you if necessary. What it does mean though is that you should not use the same Material for rendering OverlayElements as standard scene objects. It's fine to use the same textures, just not the same Material.

Reimplemented in Ogre::PanelOverlayElement, and Ogre::TextAreaOverlayElement.

Tell the object to recalculate.

Reimplemented in Ogre::OverlayContainer.

virtual void Ogre::OverlayElement::_update ( void   )  [virtual]

Internal method to update the element based on transforms applied.

virtual void Ogre::OverlayElement::_getClippingRegion ( Rectangle clippingRegion  )  [virtual]

Gets the clipping region of the element.

virtual ushort Ogre::OverlayElement::_notifyZOrder ( ushort  newZOrder  )  [virtual]

Internal method to notify the element when Zorder of parent overlay has changed.

Remarks:
Overlays have explicit Z orders. OverlayElements do not, they inherit the ZOrder of the overlay, and the Zorder is incremented for every container nested within this to ensure that containers are displayed behind contained items. This method is used internally to notify the element of a change in final zorder which is used to render the element.
Returns:
Return the next zordering number available. For single elements, this is simply newZOrder + 1, but for containers, they increment it once for each child (more if those children are also containers).

Reimplemented in Ogre::OverlayContainer.

virtual void Ogre::OverlayElement::_notifyWorldTransforms ( const Matrix4 xform  )  [virtual]

Internal method to notify the element when it's world transform of parent overlay has changed.

Reimplemented in Ogre::OverlayContainer.

void Ogre::OverlayElement::visitRenderables ( Renderable::Visitor visitor,
bool  debugRenderables = false 
)

Method to allow a caller to abstractly iterate over the Renderable instances that this MovableObject will add to the render queue when asked, if any.

Parameters:
visitor Pointer to a class implementing the Renderable::Visitor interface which will be called back for each Renderable which will be queued. Bear in mind that the state of the Renderable instances may not be finalised depending on when you call this.
debugRenderables If false, only regular renderables will be visited (those for normal display). If true, debug renderables will be included too.

Reimplemented in Ogre::BorderPanelOverlayElement.

virtual const String& Ogre::OverlayElement::getTypeName ( void   )  const [pure virtual]

Gets the type name of the element.

All concrete subclasses must implement this.

Implemented in Ogre::BorderPanelOverlayElement, Ogre::PanelOverlayElement, and Ogre::TextAreaOverlayElement.

virtual void Ogre::OverlayElement::setCaption ( const DisplayString text  )  [virtual]

Sets the caption on elements that support it.

Remarks:
This property doesn't do something on all elements, just those that support it. However, being a common requirement it is in the top-level interface to avoid having to set it via the StringInterface all the time.

Reimplemented in Ogre::TextAreaOverlayElement.

virtual const DisplayString& Ogre::OverlayElement::getCaption ( void   )  const [virtual]

Gets the caption for this element.

virtual void Ogre::OverlayElement::setColour ( const ColourValue col  )  [virtual]

Sets the colour on elements that support it.

Remarks:
This property doesn't do something on all elements, just those that support it. However, being a common requirement it is in the top-level interface to avoid having to set it via the StringInterface all the time.

Reimplemented in Ogre::TextAreaOverlayElement.

virtual const ColourValue& Ogre::OverlayElement::getColour ( void   )  const [virtual]

Gets the colour for this element.

Reimplemented in Ogre::TextAreaOverlayElement.

virtual void Ogre::OverlayElement::setMetricsMode ( GuiMetricsMode  gmm  )  [virtual]

Tells this element how to interpret the position and dimension values it is given.

Remarks:
By default, OverlayElements are positioned and sized according to relative dimensions of the screen. This is to ensure portability between different resolutions when you want things to be positioned and sized the same way across all resolutions. However, sometimes you want things to be sized according to fixed pixels. In order to do this, you can call this method with the parameter GMM_PIXELS. Note that if you then want to place your element relative to the center, right or bottom of it's parent, you will need to use the setHorizontalAlignment and setVerticalAlignment methods.

Reimplemented in Ogre::BorderPanelOverlayElement, and Ogre::TextAreaOverlayElement.

virtual GuiMetricsMode Ogre::OverlayElement::getMetricsMode ( void   )  const [virtual]

Retrieves the current settings of how the element metrics are interpreted.

virtual void Ogre::OverlayElement::setHorizontalAlignment ( GuiHorizontalAlignment  gha  )  [virtual]

Sets the horizontal origin for this element.

Remarks:
By default, the horizontal origin for a OverlayElement is the left edge of the parent container (or the screen if this is a root element). You can alter this by calling this method, which is especially useful when you want to use pixel-based metrics (see setMetricsMode) since in this mode you can't use relative positioning.
For example, if you were using GMM_PIXELS metrics mode, and you wanted to place a 30x30 pixel crosshair in the center of the screen, you would use GHA_CENTER with a 'left' property of -15.
Note that neither GHA_CENTER or GHA_RIGHT alter the position of the element based on it's width, you have to alter the 'left' to a negative number to do that; all this does is establish the origin. This is because this way you can align multiple things in the center and right with different 'left' offsets for maximum flexibility.

virtual GuiHorizontalAlignment Ogre::OverlayElement::getHorizontalAlignment ( void   )  const [virtual]

Gets the horizontal alignment for this element.

virtual void Ogre::OverlayElement::setVerticalAlignment ( GuiVerticalAlignment  gva  )  [virtual]

Sets the vertical origin for this element.

Remarks:
By default, the vertical origin for a OverlayElement is the top edge of the parent container (or the screen if this is a root element). You can alter this by calling this method, which is especially useful when you want to use pixel-based metrics (see setMetricsMode) since in this mode you can't use relative positioning.
For example, if you were using GMM_PIXELS metrics mode, and you wanted to place a 30x30 pixel crosshair in the center of the screen, you would use GHA_CENTER with a 'top' property of -15.
Note that neither GVA_CENTER or GVA_BOTTOM alter the position of the element based on it's height, you have to alter the 'top' to a negative number to do that; all this does is establish the origin. This is because this way you can align multiple things in the center and bottom with different 'top' offsets for maximum flexibility.

virtual GuiVerticalAlignment Ogre::OverlayElement::getVerticalAlignment ( void   )  const [virtual]

Gets the vertical alignment for this element.

virtual bool Ogre::OverlayElement::contains ( Real  x,

virtual void Ogre::StringInterface::copyParametersTo ( StringInterface dest  )  const [virtual, inherited]

Method for copying this object's parameters to another object.

Remarks:
This method takes the values of all the object's parameters and tries to set the same values on the destination object. This provides a completely type independent way to copy parameters to other objects. Note that because of the String manipulation involved, this should not be regarded as an efficient process and should be saved for times outside of the rendering loop.
Any unrecognised parameters will be ignored as with setParameter method.
Parameters:
dest Pointer to object to have it's parameters set the same as this object.

static void Ogre::StringInterface::cleanupDictionary (  )  [static, inherited]

Cleans up the static 'msDictionary' required to reset Ogre, otherwise the containers are left with invalid pointers, which will lead to a crash as soon as one of the ResourceManager implementers (e.g.

MaterialManager) initializes.

virtual Technique* Ogre::Renderable::getTechnique ( void   )  const [virtual, inherited]

Retrieves a pointer to the Material Technique this renderable object uses.

Remarks:
This is to allow Renderables to use a chosen Technique if they wish, otherwise they will use the best Technique available for the Material they are using.

Reimplemented in Ogre::InstancedGeometry::GeometryBucket, Ogre::StaticGeometry::GeometryBucket, and Ogre::SubEntity.

virtual void Ogre::Renderable::getRenderOperation ( RenderOperation op  )  [pure virtual, inherited]

virtual bool Ogre::Renderable::preRender ( SceneManager sm,
RenderSystem rsys 
) [virtual, inherited]

Called just prior to the Renderable being rendered.

Remarks:
OGRE is a queued renderer, so the actual render commands are executed at a later time than the point at which an object is discovered to be visible. This allows ordering & grouping of renders without the discovery process having to be aware of it. It also means OGRE uses declarative render information rather than immediate mode rendering - this is very useful in that certain effects and processes can automatically be applied to a wide range of scenes, but the downside is that special cases are more difficult to handle, because there is not the declared state to cope with it.
This method allows a Renderable to do something special at the actual point of rendering if it wishes to. When this method is called, all the material render state as declared by this Renderable has already been set, all that is left to do is to bind the buffers and perform the render. The Renderable may modify render state itself if it wants to (and restore it in the postRender call) before the automated render happens, or by returning 'false' from this method can actually suppress the automatic render and perform one of its own.
Returns:
true if the automatic render should proceed, false to skip it on the assumption that the Renderable has done it manually.

Definition at line 116 of file OgreRenderable.h.

virtual void Ogre::Renderable::postRender ( SceneManager sm,
RenderSystem rsys 
) [virtual, inherited]

Called immediately after the Renderable has been rendered.

Definition at line 119 of file OgreRenderable.h.

virtual unsigned short Ogre::Renderable::getNumWorldTransforms ( void   )  const [virtual, inherited]

Returns the number of world transform matrices this renderable requires.

Remarks:
When a renderable uses vertex blending, it uses multiple world matrices instead of a single one. Each vertex sent to the pipeline can reference one or more matrices in this list with given weights. If a renderable does not use vertex blending this method returns 1, which is the default for simplicity.

Reimplemented in Ogre::BorderRenderable, Ogre::InstancedGeometry::GeometryBucket, and Ogre::SubEntity.

Definition at line 143 of file OgreRenderable.h.

void Ogre::Renderable::setUseIdentityProjection ( bool  useIdentityProjection  )  [inherited]

Sets whether or not to use an 'identity' projection.

Remarks:
Usually Renderable objects will use a projection matrix as determined by the active camera. However, if they want they can cancel this out and use an identity projection, which effectively projects in 2D using a {-1, 1} view space. Useful for overlay rendering. Normal renderables need not change this. The default is false.

Renderable::getUseIdentityProjection

Definition at line 154 of file OgreRenderable.h.

bool Ogre::Renderable::getUseIdentityProjection ( void   )  const [inherited]

Returns whether or not to use an 'identity' projection.

void Ogre::Renderable::setUseIdentityView ( bool  useIdentityView  )  [inherited]

Sets whether or not to use an 'identity' view.

Remarks:
Usually Renderable objects will use a view matrix as determined by the active camera. However, if they want they can cancel this out and use an identity matrix, which means all geometry is assumed to be relative to camera space already. Useful for overlay rendering. Normal renderables need not change this. The default is false.

virtual bool Ogre::Renderable::getCastsShadows ( void   )  const [virtual, inherited]

Method which reports whether this renderable would normally cast a shadow.

Remarks:
Subclasses should override this if they could have been used to generate a shadow.

Reimplemented in Ogre::InstancedGeometry::GeometryBucket, Ogre::StaticGeometry::GeometryBucket, and Ogre::SubEntity.

Definition at line 214 of file OgreRenderable.h.

void Ogre::Renderable::setCustomParameter ( size_t  index,
const Vector4 value 
) [inherited]

Sets a custom parameter for this Renderable, which may be used to drive calculations for this specific Renderable, like GPU program parameters.

Remarks:
Calling this method simply associates a numeric index with a 4-dimensional value for this specific Renderable. This is most useful if the material which this Renderable uses a vertex or fragment program, and has an ACT_CUSTOM parameter entry. This parameter entry can refer to the index you specify as part of this call, thereby mapping a custom parameter for this renderable to a program parameter.
Parameters:
index The index with which to associate the value. Note that this does not have to start at 0, and can include gaps. It also has no direct correlation with a GPU program parameter index - the mapping between the two is performed by the ACT_CUSTOM entry, if that is used.
value The value to associate.

Definition at line 231 of file OgreRenderable.h.

const Vector4& Ogre::Renderable::getCustomParameter ( size_t  index  )  const [inherited]

Gets the custom value associated with this Renderable at the given index.

Parameters:
@see setCustomParaemter for full details.

References Ogre::Exception::ERR_ITEM_NOT_FOUND, and OGRE_EXCEPT.

virtual void Ogre::Renderable::_updateCustomGpuParameter ( const GpuProgramParameters::AutoConstantEntry constantEntry,
GpuProgramParameters params 
) const [virtual, inherited]

Update a custom GpuProgramParameters constant which is derived from information only this Renderable knows.

Remarks:
This method allows a Renderable to map in a custom GPU program parameter based on it's own data. This is represented by a GPU auto parameter of ACT_CUSTOM, and to allow there to be more than one of these per Renderable, the 'data' field on the auto parameter will identify which parameter is being updated. The implementation of this method must identify the parameter being updated, and call a 'setConstant' method on the passed in GpuProgramParameters object, using the details provided in the incoming auto constant setting to identify the index at which to set the parameter.
You do not need to override this method if you're using the standard sets of data associated with the Renderable as provided by setCustomParameter and getCustomParameter. By default, the implementation will map from the value indexed by the 'constantEntry.data' parameter to a value previously set by setCustomParameter. But custom Renderables are free to override this if they want, in any case.
Parameters:
constantEntry The auto constant entry referring to the parameter being updated
params The parameters object which this method should call to set the updated parameters.
