Constructor & Destructor Documentation

ThemeEngine()

GUI::ThemeEngine::ThemeEngine	(	Common::String	id,
		GraphicsMode	mode
	)

Default constructor

~ThemeEngine()

GUI::ThemeEngine::~ThemeEngine

(

)

Default destructor

Member Function Documentation

getPixelFormat()

const Graphics::PixelFormat GUI::ThemeEngine::getPixelFormat ( ) const

inline

Query the set up pixel format.

applyScreenShading()

void GUI::ThemeEngine::applyScreenShading

(

ShadingStyle

shading

)

Draw full screen shading with the supplied style

This is used to dim the inactive dialogs so the active one stands out.

drawToBackbuffer()

void GUI::ThemeEngine::drawToBackbuffer

(

)

Sets the active drawing surface to the back buffer.

All drawing from this point on will be done on that surface. The back buffer surface needs to be copied to the screen surface in order to become visible.

drawToScreen()

void GUI::ThemeEngine::drawToScreen

(

)

Sets the active drawing surface to the screen.

All drawing from this point on will be done on that surface.

updateScreen()

void GUI::ThemeEngine::updateScreen

(

)

The updateScreen() method is called every frame. It copies dirty rectangles in the Screen surface to the overlay.

copyBackBufferToScreen()

void GUI::ThemeEngine::copyBackBufferToScreen

(

)

Copy the entire backbuffer surface to the screen surface

swapClipRect()

Common::Rect GUI::ThemeEngine::swapClipRect

(

const Common::Rect &

newRect

)

Set the clipping rect to be used by the widget drawing methods defined below.

Widgets are not drawn outside of the clipping rect. Widgets that overlap the clipping rect are drawn partially.

Parameters

newRect

The new clipping rect

Returns

The previous clipping rect

disableClipRect()

void GUI::ThemeEngine::disableClipRect

(

)

Set the clipping rect to allow rendering on the whole surface.

addDirtyRect()

void GUI::ThemeEngine::addDirtyRect

(

r

)

Actual implementation of a dirty rect handling. Dirty rectangles are queued on a list, merged and optimized when possible and are later used for the actual drawing.

Parameters

r	Area of the dirty rect.

parseDrawDataId()

DrawData GUI::ThemeEngine::parseDrawDataId

(

const Common::String &

name

)

const

Returns the DrawData enumeration value that represents the given string in the DrawDataDefaults enumeration. It's slow, but called sparsely.

Returns

The drawdata enum value, or -1 if not found.

Parameters

name	The representing name, as found on Theme Description XML files.

kDrawDataDefaults[]

addDrawStep()

void GUI::ThemeEngine::addDrawStep	(	const Common::String &	drawDataId,
		const Graphics::DrawStep &	step
	)

Interface for ThemeParser class: Parsed DrawSteps are added via this function. There is no return type because DrawSteps can always be added, unless something goes horribly wrong. The specified step will be added to the Steps list of the given DrawData id.

Parameters

drawDataId	The representing DrawData name, as found on Theme Description XML files.
step	The actual DrawStep struct to be added.

addDrawData()

bool GUI::ThemeEngine::addDrawData	(	const Common::String &	data,
		bool	cached
	)

Interface for the ThemeParser class: Parsed DrawData sets are added via this function. The goal of the function is to initialize each DrawData set before their DrawSteps can be added, hence this must be called for each DD set before addDrawStep() can be called for that given set.

Parameters

data	The representing DrawData name, as found on Theme Description XML files.
cached	Whether this DD set will be cached beforehand.

addFont()

bool GUI::ThemeEngine::addFont	(	TextData	textId,
		const Common::String &	language,
		const Common::String &	file,
		const Common::String &	scalableFile,
		const int	pointsize
	)

Interface for the ThemeParser class: Loads a font to use on the GUI from the given filename.

Parameters

textId	Identifier name for the font.
language	Wildcard for the language(s) to use.
file	Filename of the non-scalable font version.
scalableFile	Filename of the scalable version. (Optional)
pointsize	Point size for the scalable font. (Optional)

storeFontNames()

void GUI::ThemeEngine::storeFontNames	(	TextData	textId,
		const Common::String &	language,
		const Common::String &	file,
		const Common::String &	scalableFile,
		const int	pointsize
	)

Store language specific font names for ingame GUI dialogs which might require a different language than the current GUI setting

Parameters

textId,language,file,scalableFile,pointsize

All exactly the same as with addFont()

loadExtraFont()

bool GUI::ThemeEngine::loadExtraFont	(	FontStyle	style,
		Common::Language	lang
	)

Load language specific font for ingame use

Parameters

style	font style associated with the font file
lang	language associated with the font file

Returns

addTextColor()

bool GUI::ThemeEngine::addTextColor	(	TextColor	colorId,
		int	r,
		int	g,
		int	b
	)

Interface for the ThemeParser class: adds a text color value.

Parameters

colorId	Identifier for the color type.
r	Red color component
g	Green color component
b	Blue color component

addBitmap()

bool GUI::ThemeEngine::addBitmap	(	const Common::String &	filename,
		const Common::String &	scalablefile,
		int	widht,
		int	height
	)

Interface for the ThemeParser class: Loads a bitmap file to use on the GUI. The filename is also used as its identifier.

Parameters

filename	Name of the bitmap file.
filename	Name of the scalable (SVG) file, could be empty
width,height	Default image dimensions

addTextData()

bool GUI::ThemeEngine::addTextData	(	const Common::String &	drawDataId,
		TextData	textId,
		TextColor	id,
		Graphics::TextAlign	alignH,
		TextAlignVertical	alignV
	)

Adds a new TextStep from the ThemeParser. This will be deprecated/removed once the new Font API is in place. FIXME: Is that so ???

ready()

bool GUI::ThemeEngine::ready ( ) const

inlineprotected

setGraphicsMode()

void GUI::ThemeEngine::setGraphicsMode ( GraphicsMode  mode )

createCursor()

bool GUI::ThemeEngine::createCursor	(	const Common::String &	filename,
		int	hotspotX,
		int	hotspotY
	)

Interface for the Theme Parser: Creates a new cursor by loading the given bitmap and sets it as the active cursor.
