virtual void Ogre::OverlayElement::_notifyParent	(	OverlayContainer *	parent,
		Overlay *	overlay
	)		`[virtual, inherited]`

Internal method for notifying the GUI element of it's parent and ultimate overlay.

Reimplemented in Ogre::OverlayContainer.

virtual void Ogre::OverlayElement::_notifyViewport ( ) [virtual, inherited]

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

Reimplemented in Ogre::OverlayContainer.

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

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

Reimplemented in Ogre::OverlayContainer.

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

Internal method to notify the element when Z-order of parent overlay has changed.

Remarks:: Overlays have explicit Z-orders. OverlayElements do not, they inherit the Z-order of the overlay, and the Z-order 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 Z-order which is used to render the element.

Returns:: Return the next Z-ordering number available. For single elements, this is simply 'newZOrder + 1', except for containers. They increment it once for each child (or even more if those children are also containers with their own elements).

Reimplemented in Ogre::OverlayContainer.

virtual void Ogre::OverlayElement::_positionsOutOfDate ( void ) [virtual, inherited]

Tell the object to recalculate.

Reimplemented in Ogre::OverlayContainer.

void Ogre::OverlayElement::_setHeight ( Real height ) [inherited]

Sets the height of this element in relation to the screen (where 1.0 = screen width)

void Ogre::OverlayElement::_setLeft ( Real left ) [inherited]

Sets the left of this element in relation to the screen (where 1.0 = screen width)

void Ogre::OverlayElement::_setParent ( OverlayContainer * parent ) [inherited]

Definition at line 460 of file OgreOverlayElement.h.

void Ogre::OverlayElement::_setPosition	(	Real	left,
		Real	top
	)		`[inherited]`

Sets the left and top of this element in relation to the screen (where 1.0 = screen width)

void Ogre::OverlayElement::_setTop ( Real top ) [inherited]

Sets the top of this element in relation to the screen (where 1.0 = screen width)

void Ogre::OverlayElement::_setWidth ( Real width ) [inherited]

Sets the width of this element in relation to the screen (where 1.0 = screen width)

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

Overridden from OverlayElement.

Reimplemented from Ogre::OverlayElement.

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.

Reimplemented in Ogre::SubEntity.

virtual void Ogre::OverlayElement::_updateRenderQueue ( RenderQueue * queue ) [virtual, inherited]

Internal method to put the contents onto the render queue.

Reimplemented in Ogre::BorderPanelOverlayElement, Ogre::OverlayContainer, and Ogre::PanelOverlayElement.

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

Method for setting up base parameters for this class.

Reimplemented from Ogre::OverlayElement.

void Ogre::TextAreaOverlayElement::checkMemoryAllocation ( size_t numChars ) [protected]

Internal method to allocate memory, only reallocates when necessary.

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 OverlayElement* Ogre::OverlayElement::clone ( const String & instanceName ) [virtual, inherited]

Reimplemented in Ogre::OverlayContainer.

virtual bool Ogre::OverlayElement::contains	(	Real	x,
		Real	y
	)		const `[virtual, inherited]`

Returns true if xy is within the constraints of the component.

virtual void Ogre::OverlayElement::copyFromTemplate ( OverlayElement * templateOverlay ) [virtual, inherited]

Reimplemented in Ogre::OverlayContainer.

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.

References Ogre::ParamDictionary::mParamDefs, and Ogre::StringInterface::setParameter().

bool Ogre::StringInterface::createParamDictionary ( const String & className ) [protected, inherited]

Internal method for creating a parameter dictionary for the class, if it does not already exist.

Remarks:: This method will check to see if a parameter dictionary exist for this class yet, and if not will create one. NB you must supply the name of the class (RTTI is not used or performance).

Parameters:

className the name of the class using the dictionary

Returns:: true if a new dictionary was created, false if it was already there

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

Returns 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.

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

Returns 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.

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

Called immediately after the Renderable has been rendered.

Definition at line 128 of file OgreRenderable.h.

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.

virtual void Ogre::OverlayElement::setCloneable ( bool c ) [virtual, inherited]

Definition at line 453 of file OgreOverlayElement.h.

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

Sets the colour of the text.

Remarks:: This method establishes a constant colour for the entire text. Also see setColourBottom and setColourTop which allow you to set a colour gradient.

Reimplemented from Ogre::OverlayElement.

void Ogre::TextAreaOverlayElement::setColourBottom ( const ColourValue & col )

Sets the colour of the bottom of the letters.

Remarks:: By setting a separate top and bottom colour, you can create a text area which has a graduated colour effect to it.

void Ogre::TextAreaOverlayElement::setColourTop ( const ColourValue & col )

Sets the colour of the top of the letters.

Remarks:: By setting a separate top and bottom colour, you can create a text area which has a graduated colour effect to it.

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.

void Ogre::OverlayElement::setDimensions	(	Real	width,
		Real	height
	)		`[inherited]`

virtual void Ogre::OverlayElement::setEnabled ( bool b ) [virtual, inherited]

void Ogre::TextAreaOverlayElement::setFontName ( const String & font )

void Ogre::OverlayElement::setHeight ( Real height ) [inherited]

Sets the height of this element in relation to the screen (where 1.0 = screen height)

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

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.

void Ogre::OverlayElement::setLeft ( Real left ) [inherited]

Sets the left of this element in relation to the screen (where 0 = far left, 1.0 = far right)

virtual bool Ogre::StringInterface::setParameter	(	const String &	name,
		const String &	value
	)		`[virtual, inherited]`

Generic parameter setting method.

Remarks:: Call this method with the name of a parameter and a string version of the value to set. The implementor will convert the string to a native type internally. If in doubt, check the parameter definition in the list returned from StringInterface::getParameters.

Parameters:

name	The name of the parameter to set
value	String value. Must be in the right format for the type specified in the parameter definition. See the StringConverter class for more information.

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

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.
