initialise()

virtual void Ogre::TextAreaOverlayElement::initialise ( void  )

virtual

Initialise gui element.

Implements Ogre::OverlayElement.

_releaseManualHardwareResources()

virtual void Ogre::TextAreaOverlayElement::_releaseManualHardwareResources ( )

virtual

Notifies that hardware resources were lost.

Reimplemented from Ogre::OverlayElement.

_restoreManualHardwareResources()

virtual void Ogre::TextAreaOverlayElement::_restoreManualHardwareResources ( )

virtual

Notifies that hardware resources should be restored.

Reimplemented from Ogre::OverlayElement.

setCaption()

virtual void Ogre::TextAreaOverlayElement::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 from Ogre::OverlayElement.

Remarks

Note that the Renderable also has the option to override the getTechnique method to specify a particular Technique to use instead of the best one available.

Reimplemented from Ogre::OverlayElement.

getRenderOperation()

void Ogre::TextAreaOverlayElement::getRenderOperation ( RenderOperation &  op )

overridevirtual

Gets the colour of the text.

Reimplemented from Ogre::OverlayElement.

setColourBottom()

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.

getColourBottom()

(

void

)

const

Gets the colour of the bottom of the letters.

setColourTop()

void Ogre::TextAreaOverlayElement::setColourTop
