Detailed Description

OverlayElement representing a flat, single-material (or transparent) panel which can contain other elements.

Remarks:
This class subclasses OverlayContainer because it can contain other elements. Like other containers, if hidden it's contents are also hidden, if moved it's contents also move etc. The panel itself is a 2D rectangle which is either completely transparent, or is rendered with a single material. The texture(s) on the panel can be tiled depending on your requirements.
This component is suitable for backgrounds and grouping other elements. Note that because it has a single repeating material it cannot have a discrete border (unless the texture has one and the texture is tiled only once). For a bordered panel, see it's subclass BorderTextAreaOverlayElement.
Note that the material can have all the usual effects applied to it like multiple texture layers, scrolling / animated textures etc. For multiple texture layers, you have to set the tiling level for each layer.

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

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.

Reimplemented in Ogre::OverlayContainer.

Tell the object to recalculate.

Reimplemented in Ogre::OverlayContainer.

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, and Ogre::TerrainRenderable.

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

Method for setting up base parameters for this class.

Reimplemented from Ogre::OverlayElement.

Internal method to allocate memory, only reallocates when necessary.

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.

Real  y
const [virtual, inherited]
 

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

void Ogre::OverlayElement::copyFromTemplate OverlayElement templateOverlay  )  [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

void Ogre::TextAreaOverlayElement::setCaption const String caption  )  [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 from Ogre::OverlayElement.

void Ogre::TextAreaOverlayElement::setCharHeight Real  height  ) 
 

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

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]
 

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

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).

void Ogre::TextAreaOverlayElement::setMaterialName const String matName  )  [virtual]
 

Overridden from OverlayElement.

Reimplemented from Ogre::OverlayElement.

void Ogre::TextAreaOverlayElement::setMetricsMode GuiMetricsMode  gmm  )  [virtual]
 

Overridden from OverlayElement.

Reimplemented from Ogre::OverlayElement.

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.
Returns:
true if set was successful, false otherwise (NB no exceptions thrown - tolerant method)

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

virtual void Ogre::StringInterface::setParameterList const NameValuePairList paramList  )  [virtual, inherited]
 

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:
paramList Name/value pair list

virtual void Ogre::Renderable::setPolygonModeOverrideable bool  override  )  [virtual, inherited]
 

Sets whether this renderable's chosen detail level can be overridden (downgraded) by the camera setting.

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

Definition at line 231 of file OgreRenderable.h.

void Ogre::OverlayElement::setPosition Real  left,
Real  top
[inherited]
 

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

void Ogre::TextAreaOverlayElement::setSpaceWidth Real  width  ) 
 

void Ogre::OverlayElement::setTop Real  Top  )  [inherited]
 

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

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.

void Ogre::OverlayElement::setWidth Real  width  )  [inherited]
 

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

virtual void Ogre::OverlayElement::show void   )  [virtual, inherited]
 

Shows this element if it was hidden.
