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.

Use case: If you will be destroying an HlmsDatablock and all Renderables associated by it; it makes no sense to change the Renderable's datablock to a default one, only to be destroyed immediately after (you pay an unnecessary performance price).

Remarks
Do not attempt to render a Renderable whose datablock has been set to null. It will crash. You can call setDatablock afterwards though. Use at your own risk, hence the _underscore. See http://ogre3d.org/forums/viewtopic.php?f=25&t=91791&p=534476#p534476

◆ _updateCustomGpuParameter()

virtual void Ogre::Renderable::_updateCustomGpuParameter ( const GpuProgramParameters_AutoConstantEntry constantEntry,
GpuProgramParameters params 
) const
virtualinherited

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
constantEntryThe auto constant entry referring to the parameter being updated
paramsThe parameters object which this method should call to set the updated parameters.

Reimplemented in Ogre::v1::SubEntity.

◆ _updateFromParent()

◆ addPoseWeight()

void Ogre::Renderable::addPoseWeight ( size_t  index,
float  w 
)
inherited

◆ cleanupDictionary()

static void Ogre::StringInterface::cleanupDictionary ( )
staticinherited

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.

◆ clone()

virtual OverlayElement* Ogre::v1::OverlayElement::clone ( const String instanceName)
virtual

Reimplemented in Ogre::v1::OverlayContainer.

◆ contains()

virtual bool Ogre::v1::OverlayElement::contains ( Real  x,
Real  y 
) const
virtual

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

virtual void Ogre::v1::OverlayElement::copyFromTemplate ( OverlayElement templateOverlay)
virtual

Reimplemented in Ogre::v1::OverlayContainer.

◆ copyParametersTo()

virtual void Ogre::StringInterface::copyParametersTo ( StringInterface dest) const
inlinevirtualinherited

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
destPointer to object to have it's parameters set the same as this object.

References Ogre::StringInterface::setParameter().

◆ findElementAt()

inlinevirtualinherited

Generic parameter retrieval method.

Remarks
Call this method with the name of a parameter to retrieve a string-format value of the parameter in question. If in doubt, check the parameter definition in the list returned from getParameters for the type of this parameter.

◆ getUseIdentityProjection()

bool Ogre::Renderable::getUseIdentityProjection ( ) const
inlineinherited

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.

Renderable::setUseIdentityProjection

◆ getUseIdentityView()

bool Ogre::Renderable::getUseIdentityView ( ) const
inlineinherited

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.

◆ getUseIdentityViewProjMatrixIsDynamic()

virtual bool Ogre::Renderable::getUseIdentityViewProjMatrixIsDynamic ( ) const
inlinevirtualinherited

Returns whether the Hlms implementation should evaluate getUseIdentityProjection per object at runtime, or if it can assume the Renderable will remain with the same setting until the datablock is flushed (performance optimization)

Remarks
Hlms implementations may ignore this setting (e.g. assume always true or always false) or even not support identity matrix overrides at all. For example currently Unlit supports them all, but will assume this returns always true if getUseIdentityWorldMatrix returns false.

◆ getUseIdentityWorldMatrix()

virtual bool Ogre::Renderable::getUseIdentityWorldMatrix ( ) const
inlinevirtualinherited

Returns whether the world matrix is an identity matrix.

Remarks
It is up to the Hlms implementation whether to honour this request. Take in mind changes of this value at runtime may not be seen until the datablock is flushed. It is implemented as a virtual call because this functionality isn't required very often (hence we save per-Renderable space for those that don't use it) and this function will be called at creation time to use a different shader; not during rendering time per Renderable.

Reimplemented in Ogre::v1::BillboardSet.

◆ postRender()

virtual void Ogre::Renderable::postRender ( SceneManager sm,
RenderSystem rsys 
)
inlinevirtualinherited

Called immediately after the Renderable has been rendered.

◆ preRender()

virtual bool Ogre::Renderable::preRender ( SceneManager sm,
RenderSystem rsys 
)
inlinevirtualinherited

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.

Reimplemented in Ogre::v1::BillboardChain.

◆ removeCustomParameter()

void Ogre::Renderable::removeCustomParameter ( size_t  index)

◆ setCaption()

virtual void Ogre::v1::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::v1::TextAreaOverlayElement.

◆ setCloneable()

◆ setColour()

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::v1::TextAreaOverlayElement.

◆ setCustomParameter()

void Ogre::Renderable::setCustomParameter ( size_t  index,
const Vector4 value 
)
inlineinherited

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
indexThe 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.
valueThe value to associate.

◆ setDatablock() [1/2]

virtual void Ogre::Renderable::setDatablock ( HlmsDatablock datablock)
virtualinherited

Assigns a datablock (i.e. HLMS Material) to this renderable.

Reimplemented in Ogre::v1::SubEntity, and Ogre::v1::BillboardSet.

◆ setDatablock() [2/2]

void Ogre::Renderable::setDatablock ( IdString  datablockName)
inherited

Assigns a datablock (i.e.

HLMS material) based on its unique name.

Remarks
An null IdString() is valid, it will use the default material

◆ setDatablockOrMaterialName()

void Ogre::Renderable::setDatablockOrMaterialName ( String  materialName,
String  groupName 
)
inherited

First tries to see if an HLMS datablock exist with the given name, if not, tries to search among low level materials.

◆ setDefaultRenderQueueSubGroup()

static void Ogre::Renderable::setDefaultRenderQueueSubGroup ( uint8  subGroup)
inlinestaticinherited

Sets the default render queue sub group for all future Renderable instances.

◆ setDimensions()

void Ogre::v1::OverlayElement::setDimensions ( Real  width,
Real  height 
)

Sets the dimensions of this element in relation to the screen (1.0 = screen width/height).

◆ setEnabled()

virtual void Ogre::v1::OverlayElement::setEnabled ( bool  b)
virtual

◆ setHeight()

void Ogre::v1::OverlayElement::setHeight ( Real  height)

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

◆ setHorizontalAlignment()

virtual void Ogre::v1::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.

◆ setLeft()

void Ogre::v1::OverlayElement::setLeft ( Real  left)

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

◆ setMaterial()

virtual void Ogre::Renderable::setMaterial ( const MaterialPtr material)
virtualinherited

Sets the given material. Overrides HLMS materials.

Reimplemented in Ogre::v1::SubEntity, Ogre::v1::BillboardSet, and Ogre::v1::SimpleRenderable.

◆ setMaterialName() [1/2]

virtual void Ogre::v1::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::v1::TextAreaOverlayElement, and Ogre::v1::PanelOverlayElement.

◆ setMaterialName() [2/2]

void Ogre::Renderable::setMaterialName ( const String name,
const String groupName 
)
inherited

Sets the name of the Material to be used. Prefer using HLMS @See setHlms.

◆ setMetricsMode()

virtual void Ogre::v1::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::v1::TextAreaOverlayElement, and Ogre::v1::BorderPanelOverlayElement.

◆ setParameter()

virtual bool Ogre::StringInterface::setParameter ( const String name,
const String value 
)
virtualinherited

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
nameThe name of the parameter to set
valueString value. Must be in the right format for the type specified in the parameter definition. See the StringConverter class for more information.
Returns
true if set was successful, false otherwise (NB no exceptions thrown - tolerant method)

Referenced by Ogre::StringInterface::copyParametersTo().

◆ setParameterList()

virtual void Ogre::StringInterface::setParameterList ( const NameValuePairList paramList)
virtualinherited

Generic multiple parameter setting method.

Remarks
Call this method with a list of name / value pairs 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

◆ setPolygonModeOverrideable()

virtual void Ogre::Renderable::setPolygonModeOverrideable ( bool  override)
inlinevirtualinherited

Parameters
overridetrue means that a lower camera detail will override this renderables detail level, false means it won't.

◆ setPoseWeight()

float  w 
)
inherited

◆ setPosition()

void Ogre::v1::OverlayElement::setPosition ( Real  left,
Real  top 
)

Sets the position of the top-left corner of the element, relative to the screen size (1.0 = screen width / height)

◆ setRenderQueueSubGroup()

void Ogre::Renderable::setRenderQueueSubGroup ( uint8  subGroup)
inlineinherited

Sets the render queue sub group.

Remarks
Within the same RenderQueue ID, you may want to have the renderables to have a specific order (i.e. have a mesh, but the hair submesh with alpha blending needs to be rendered last).
RenderQueue Subgroups are useful for manually sorting objects, just like RenderQueue IDs. However, RenderQueue IDs can also be useful for skipping large number of objects through clever compositing and thus a performance optimization. Subgroups cannot be used for such optimizations.
Parameters
subGroupThe sub group. This value can't exceed OGRE_MAKE_MASK( SubRqIdBits ) @See RenderQueue

◆ setTop()

void Ogre::v1::OverlayElement::setTop ( Real  Top)

Sets the top of this element in relation to the screen (where 0 = top, 1.0 = bottom)

◆ setUseIdentityProjection()

void Ogre::Renderable::setUseIdentityProjection ( bool  useIdentityProjection)
inlineinherited

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.

◆ setUseIdentityView()

void Ogre::Renderable::setUseIdentityView ( bool  useIdentityView)
inlineinherited

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.

◆ setUserAny()

virtual OGRE_DEPRECATED void Ogre::Renderable::setUserAny ( const Any anything)
inlinevirtualinherited
Deprecated:

Sets any kind of user value on this object.

Remarks
This method allows you to associate any user value you like with this Renderable. This can be a pointer back to one of your own classes for instance.

◆ setVerticalAlignment()

virtual void Ogre::v1::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.
