Border Size
Remember that the dimensions specified here are in relation to the size of the screen, so 0.1 is 1/10th of the screen width or height. Also note that because most screen resolutions are 1.333:1 width:height ratio that using the same border size will look slightly bigger across than up.
void	setBorderSize (Real size)
	Sets the size of the border.
void	setBorderSize (Real sides, Real topAndBottom)
	Sets the size of the border, with different sizes for vertical and horizontal borders.
void	setBorderSize (Real left, Real right, Real top, Real bottom)
	Sets the size of the border separately for all borders.
Real	getLeftBorderSize (void) const
	Gets the size of the left border.
Real	getRightBorderSize (void) const
	Gets the size of the right border.
Real	getTopBorderSize (void) const
	Gets the size of the top border.
Real	getBottomBorderSize (void) const
	Gets the size of the bottom border.
Border UV Coordinates
The border panel uses 8 panels for the border (9 including the center). Imagine a table with 3 rows and 3 columns. The corners are always the same size, but the edges stretch depending on how big the panel is. Those who have done resizable HTML tables will be familiar with this approach. We only require 2 sets of uv coordinates, one for the top-left and one for the bottom-right of the panel, since it is assumed the sections are aligned on the texture.
void	setLeftBorderUV (Real u1, Real v1, Real u2, Real v2)
	Sets the texture coordinates for the left edge of the border.
void	setRightBorderUV (Real u1, Real v1, Real u2, Real v2)

Detailed Description

A specialisation of the PanelOverlayElement to provide a panel with a border.

Whilst the standard panel can use a single tiled material, this class allows panels with a tileable backdrop plus a border texture. This is handy for large panels that are too big to use a single large texture with a border, or for multiple different size panels where you want the border a constant width but the center to repeat.

In addition to the usual PanelOverlayElement properties, this class has a 'border material', which specifies the material used for the edges of the panel, a border width (which can either be constant all the way around, or specified per edge), and the texture coordinates for each of the border sections.

_updateRenderQueue()

void Ogre::BorderPanelOverlayElement::_updateRenderQueue ( RenderQueue *  queue )

overridevirtual

Overridden from OverlayElement.

Reimplemented from Ogre::OverlayElement.

visitRenderables()

void Ogre::BorderPanelOverlayElement::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.

setMetricsMode()

void Ogre::BorderPanelOverlayElement::setMetricsMode ( GuiMetricsMode  gmm )

overridevirtual

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

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 from Ogre::OverlayElement.

_update()

void Ogre::BorderPanelOverlayElement::_update ( void  )

overridevirtual

Internal method to update the element based on transforms applied.

Reimplemented from Ogre::OverlayElement.
