Detailed Description

Widgets are graphical components that are drawn in their parent container, which is a surface.

Therefore widgets can have their own widgets too, insofar they are surfaces as well.

So, towards its parent surface, the widget is an event listener.

Being also a Surface, it can have widgets itself, and therefore would behave as an event source too.

When a widget is to be drawn, it has to be managed by its parent surface, which is the only object which is able to know how to cope with stacking and overlapping elements.

Therefore, when a widget changes, the information climbs up the surface composition tree to its root, which will result back, during the next redraw phase, to a selective redraw.

This drawing of the graphical tree is depth-first : child elements are sorted from bottom to top, they are completely drawn in turn.

Besides the inherited 'need for redraw' propagated state, which determines whether the widget needs to copy back its internal video buffer to its parent surface, a widget will have to be re-rendered on request, when its redrawInternal method will be called. Advanced widgets could rely on a backbuffer and a state attribute telling whether the widget changed, so that the redrawInternal method triggers a new rendering of this widget only when appropriate. The interest of this method depends on the balance to be found between the cost of memory resource (the back-buffer) and of CPU usage (the useless redrawings).

See also:

the BackBufferedWidget class for this behaviour.

Widgets can handle window decorations, notably for being minimized, maximized, dragged, wrapped or closed by the user. The corresponding icons may be used. Default ones are provided as 18*18 PNG icons. If one of the previous features is activated for a widget, it will trigger automatically the widget decoration.

Each widget can have either a background color (which is used to fill the widget dedicated area prior to any rendering), or a colorkey (which is used to fill as well its area and set as its colorkey, hence making it fully transparent as a whole before any special rendering which allows for non-rectangular shapes), or not color at all, so that the widget can exactly draw itself as wanted.

The meaning of this base color is determined by the base color mode.

When a colorkey is used, RLE encoding is activated to gain speed.

Member Enumeration Documentation

enum OSDL::Video::TwoDimensional::Widget::BaseColorMode

Describes the available modes for handling the base color of a widget.

Hence the base color can be the background color of a widget ('BackgroundColor'), or the color key to be used if automatic color-keying is activated ('Colorkey'). The base color can be ignored thanks to 'None'.

The 'NotInitialized' value is only to be used in constructors.

Enumerator:

BackgroundColor
Colorkey
None
NotInitialized

Constructor & Destructor Documentation

OSDL::Video::TwoDimensional::Widget::Widget	(	Surface &	container,
		const Point2D &	relativePosition,
		Length	width,
		Length	height,
		BaseColorMode	baseColorMode,
		Pixels::ColorDefinition	baseColor,
		const std::string &	title = "",
		bool	minMaximizable = true,
		bool	draggable = true,
		bool	wrappable = true,
		bool	closable = true
	)			throw ( VideoException )

Creates a new Widget, whose container surface is container.

Its container, which is always a surface (since Widgets are themselves specialized surfaces) will own this widget, therefore will deallocate it when appropriate.

Most of the widget attributes, such as bits per pixel, will be deduced from the corresponding attributes of the container surface.

A Widget is a (special) surface. This surface stores the result of the rendering of this widget and of all the renderings of subwidgets this widget may have.

As a result, a basic widget has no surface of its own, where it could store its own rendering for later use. Therefore when at least one of its subwidgets changes, it has to be veritably redrawn too, instead of which it could simply blit its own rendering, if it were stored.

To rely on such behaviour, see the BackBufferedWidget class.

Even if there is not reason for that widget to be decorated (no title, no special attributes such as maximizable activated, etc.), decoration rendering can be forced after widget creation thanks to the setDecorationStatus method.

Widgets are created by default with a pure black colorkey (Pixels::Black) and with color-keying disabled.

Parameters:

	container	this Widget's container surface, to which it will automatically be subscribed to, as an EventListener for redraw operations.
	relativePosition	tells where the upper-left corner of the widget is located inside its container.
	width	this widget's width, in pixels.
	height	this widget's height, in pixels.
	baseColorMode	is the chosen mode for base color.
	baseColor	is the base color of the widget.
	title	the title which may be drawn, if non empty, on the top of this widget.
	minMaximizable	tells whether the widget can be minimized or maximized by the user.
	draggable	tells whether the widget can be dragged by the user.
	wrappable	tells whether the widget can be wrapped (only the widget decoration is displayed) by the user.
	closable	tells whether the widget can be closed by the user.

Exceptions:

VideoException

if an error occured, for example with colorkey activation.

Note:

The stacking is set to the top position on creation. The stack level used to be inaccurately modeled as a third coordinate (depth), instead of which it is managed thanks to an ordered list in the parent container.

Parent surface cannot be 'const' since the widget may issue redraw triggers for example.

void Surface::convertToDisplay

(

Converts the internal surface to the pixel format of the display, so that any blit of this surface to the screen is quicker.

The backend must already be initialized.

Parameters:

alphaChannelWanted

tells whether this converted surface should have an alpha channel after this call.

This method can be used to convert a colorkey to an alpha channel, if the ColorkeyBlit flag is already set on this surface and if alphaChannelWanted is true. The generated surface will then be transparent (alpha=AlphaTransparent) where the pixels match the colorkey, and opaque (alpha=AlphaOpaque) elsewhere.

Exceptions:

virtual void OSDL::Video::Surface::setAlpha	(	Ceylan::Flags	flags,
		Pixels::ColorElement	newAlpha
	)			throw ( VideoException ) [virtual, inherited]

Adjusts the alpha properties of the surface : sets the per-surface alpha value and/or enables or disables alpha blending.

Parameters:

	flags	can be an OR'd combination of the following two options, one of these options, or 0 (none) : Surface::AlphaBlendingBlit Surface::RLEColorkeyBlit
	newAlpha	is the per-surface alpha value. A surface needs not to have an alpha channel to use per-surface alpha, and blitting can still be accelerated with Surface::RLEColorkeyBlit.

Note:

0 (AlphaTransparent) is considered fully transparent and 255 (AlphaOpaque) is considered fully opaque.

The per-surface alpha value of 128 is considered a special case and is optimised, so it is much faster than other per-surface values.

virtual void OSDL::Video::Surface::setColorKey	(	Ceylan::Flags	flags,
		Pixels::PixelColor	keyPixelColor
	)			throw ( VideoException ) [virtual, inherited]

Sets the color key (transparent pixel) in a blittable surface, and enables or disables RLE blit acceleration.

RLE acceleration can substantially speed up blitting of images with large horizontal runs of transparent pixels (i.e. pixels that match the key value). The key must be defined accoring to the same pixel format as the surface.

Parameters:

flag

can be a OR'ed combination : if Surface::ColorkeyBlit is set, then the key is the transparent pixel value in the source image of a blit. if Surface::RLEColorkeyBlit is set, RLE acceleration will be used when blitting this surface. The RLE encoding will be performed the first time the surface is blitted or when it will be converted to display format.

If flag is 0, this function clears any current color key.

Parameters:

keyPixelColor,the

pixel color of the key. Pixels::convertColorDefinitionToPixelColor is often useful for obtaining a correct value for the color key.

Sets the color key (transparent pixel) in a blittable surface, and enables or disables RLE blit acceleration.

RLE acceleration can substantially speed up blitting of images with large horizontal runs of transparent pixels (i.e. pixels that match the key value). The key must be defined accoring to the same pixel format as the surface.

Parameters:

flag

can be a OR'ed combination : if Surface::ColorkeyBlit is set, then the key is the transparent pixel value in the source image of a blit. if Surface::RLEColorkeyBlit is set, RLE acceleration will be used when blitting this surface. The RLE encoding will be performed the first time the surface is blitted or when it will be converted to display format.

bool Surface::blitTo

(

Surface &

targetSurface

)

const throw ( VideoException ) [virtual, inherited]

Blits this surface onto specified surface.

Blits from a RGBA Surface with AlphaBlendingBlit set to another RGBA surface will keep the alpha of the destination surface. This means that you cannot compose two arbitrary RGBA surfaces this way and get the result you would expect from "overlaying" them : the destination alpha will work as a mask. Hence one might set the alpha of the destination surface to targeted value before the blit.

Parameters:

targetSurface

the destination surface this surface will be blitted to, starting at [0;0] in the destination surface : both upper left corners will correspond.

Exceptions:

VideoMemoryLostException

if either of the surfaces was in video memory, and if the video memory was lost : it then should be reloaded with content and re-blitted. Otherwise, if blit went wrong differently, throw a commented VideoException.

Note:

Should not be called on a locked surface.

Surface & Surface::zoom	(	Ceylan::Maths::Real	abscissaZoomFactor,
		Ceylan::Maths::Real	ordinateZoomFactor,
		bool	antialiasing = true
	)			const throw ( VideoException ) [virtual, inherited]

Returns a newly created surface, obtained from this surface after a zoom of given factors.

If, for this surface, pixel color is not 8 bit or 32 bit, then a 32-bit surface will be internally created and used for the zoom.

Ownership of the returned surface is transferred to the caller, who will have to deallocate it when having finished with it.

The final rendering speed depends first on antialiasing being requested or not, then on resulting surface size.

A surface is returned instead of zooming directly this surface to avoid accumulating rounding errors when zooming multiple times the same image : better use a constant source surface from which zoomed ones are created with various zoom factors than changing the same surface again and again.

Parameters:

	abscissaZoomFactor	the zoom factor to be applied on the abscissa axis. If negative, the surface is flipped against this axis. No antialiasing will be performed in this case.
	ordinateZoomFactor	the zoom factor to be applied on the ordinate axis. If negative, the surface is flipped against this axis. No antialiasing will be performed in this case.
	antialiasing	if true and if zoom factors are positive, requests antialiasing (fine and expensive interpolation). 8-bit surfaces will never be antialiased.

Surface & Surface::rotoZoom	(	Ceylan::Maths::AngleInDegrees	angle,
		Ceylan::Maths::Real	zoomFactor,
		bool	antialiasing = true
	)			const throw ( VideoException ) [virtual, inherited]

Returns a newly created surface, obtained from this surface after a rotation of given angle and a zoom of given factor.

If, for this surface, pixel color is not 8 bit or 32 bit, then a 32-bit surface will be internally created and used for the rotozoom.

Ownership of the returned surface is transferred to the caller, who will have to deallocate it when having finished with it.

The final rendering speed depends first on antialiasing being requested or not, then on resulting surface size.

A surface is returned instead of rotating this surface to avoid accumulating rounding errors when rotozooming multiple times the same image : better use a constant source surface from which rotozoomed ones are created with various angles and zoom factors than changing the same surface again and again.

Parameters:

	angle	the angle of rotation, in degrees.
	zoomFactor	the zoom factor to be applied on both surface dimensions. If negative, the surface is rotated of Pi before the angle is applied. No antialiasing will be performed in this case.
	antialiasing	if true and if zoom factor is positive, requests antialiasing (fine and expensive interpolation). 8-bit surfaces will never be antialiased.

Returns a newly created surface, obtained from this surface after a rotation of given angle and zooms of given factors.

If, for this surface, pixel color is not 8 bit or 32 bit, then a 32-bit surface will be internally created and used for the rotozoom.

	)			throw ( TwoDimensional::ImageException ) [virtual, inherited]

Loads an image, whose format will be auto-detected, from specified file, into this surface.

This is a Surface factory.

Parameters:

	targetSurface	the surface that should correspond to the loaded image.
	filename	the name of the image file.
	blitOnly	tells whether the loaded image surface should only be blitted into the supposed already existing internal surface and then be deallocated (if flag is true), or if this loaded surface should simply replace the former one (if flag is false).

	convertWithAlpha	if the conversion to screen format is selected (convertToDisplayFormat is true), tells whether the converted surface should also have an alpha channel.

Note:

Specifying a blitOnly option set to true is especially convenient when selecting the screen's surface as target surface, since this surface is special and should not be deallocated as the others may be.

void Surface::update

(

)

throw ( VideoException ) [virtual, inherited]

Updates the display with this surface, which will be automatically set in an up-to-date state if necessary, so that it is fully redrawn, including its widgets.

If it is a screen surface (either OpenGL or not), it will be updated in order to have the display match the surface buffer. Does nothing more if this surface is not a screen surface.

Note:

When this method is called, the surface is supposed not to be locked.

• on hardware that supports double-buffering, this method sets up a flip and returns. The hardware will wait for vertical retrace, and then swap video buffers before the next video surface blit or lock will return.

on hardware that does not support double-buffering, this is equivalent to calling the updateRectangle method with all arguments to zero.

Note:

The Surface::DoubleBuffered flag must have been passed to setMode, when setting the video mode, for this function to have a chance to perform hardware flipping.

Exceptions:

virtual void OSDL::Video::Surface::updateRectangles

(

const std::list< UprightRectangle * > &

listRects

)

throw ( VideoException ) [virtual, inherited]

Updates the part of this surface corresponding to the specified list of rectangles.

Note:

The rectangles must be confined within the screen boundaries (no clipping is done).

The surface must not be locked when this method is called.

It is advised to call this method only once per frame, since each call has some processing overhead. This is no restriction, since you can pass any number of rectangles each time.

The rectangles are not automatically merged or checked for overlap. In general, the programmer can use his knowledge about his particular rectangles to merge them in an efficient way, to avoid overdraw.

Note:

STL too clumsy to understand list<const UprightRectangle const *> etc. (would require conversion by copy)

Exceptions:

VideoException

	)			throw () [virtual, inherited]

Displays specified set of data, defined by dataArray, an array of dataCount IntegerData elements, as a curve drawn with pencilColor, on a background whose color is backgroundColor.

The whole display will be scaled vertically to fit into inBox. On the contrary, the abscissa will be used as is.

Note:

If inBox is a null pointer, then the curve will be drawn in the whole surface.

When choosing the width of the container (inBox), to avoid truncating the graph, add 2*graphAbscissaOffset to the number of samples that describes the curve, and it will fit at best : both left and right boundaries will be taken into account.

DisplayType OSDL::Video::Surface::_displayType [protected, inherited]

Tells what is the display type of this surface.

The display type has to be recorded since :

• screen surfaces are not managed like backbuffers, since the formers have to update the screen
• classical screen surfaces and OpenGL ones must be distinguished, since they update the screen differently (flip in double-buffering)
