Detailed Description

Render target that uses SFML to draw the gui.

Constructor & Destructor Documentation

◆ BackendRenderTargetSFML()

tgui::BackendRenderTargetSFML::BackendRenderTargetSFML ( sf::RenderTarget & target )

Constructs the render target.

Parameters

target The SFML render target (typically sf::RenderWindow) on which the gui should be drawn

Member Function Documentation

◆ clearScreen()

void tgui::BackendRenderTargetSFML::clearScreen ( )

overridevirtual

Clears the screen, called at the beginning of each frame when gui.mainLoop() is called.

Implements tgui::BackendRenderTarget.

◆ drawGui()

void tgui::BackendRenderTargetSFML::drawGui ( const std::shared_ptr< RootContainer > & root )

overridevirtual

Draws the gui and all of its widgets.

Parameters

root	Root container that holds all widgets in the gui

Implements tgui::BackendRenderTarget.

◆ drawSprite()

void tgui::BackendRenderTargetSFML::drawSprite	(	const RenderStates &	states,
		const Sprite &	sprite
	)

overridevirtual

Draws a texture.

Parameters

states	Render states to use for drawing
sprite	Image to draw

Reimplemented from tgui::BackendRenderTarget.

◆ drawVertexArray()

void tgui::BackendRenderTargetSFML::drawVertexArray	(	const RenderStates &	states,
		const Vertex *	vertices,
		std::size_t	vertexCount,
		const int *	indices,
		std::size_t	indexCount,
		const std::shared_ptr< BackendTexture > &	texture
	)

overridevirtual

Draws a vertex array. This is called by the other draw functions when they are not overriden.

Parameters

states	Render states to use for drawing
vertices	Pointer to first element in array of vertices
vertexCount	Amount of elements in the vertex array
indices	Pointer to first element in array of indices
indexCount	Amount of elements in the indices array
texture	Texture to use, or nullptr when drawing colored triangles

Implements tgui::BackendRenderTarget.

◆ getTarget()

sf::RenderTarget * tgui::BackendRenderTargetSFML::getTarget ( ) const

Returns the SFML render target on which the gui is being drawn.

Returns: The SFML render target that is used by the gui

◆ setClearColor()

void tgui::BackendRenderTargetSFML::setClearColor ( const Color & color )

overridevirtual

Select the color that will be used by clearScreen.

Parameters

color Background color of the window

Implements tgui::BackendRenderTarget.

◆ updateClipping()

void tgui::BackendRenderTargetSFML::updateClipping	(	FloatRect	clipRect,
		FloatRect	clipViewport
	)

overrideprotectedvirtual

Called from addClippingLayer and removeClippingLayer to apply the clipping.

Parameters

clipRect	View rectangle to apply
clipViewport	Viewport to apply

Both rectangles may be empty when nothing that will be drawn is going to be visible.

Implements tgui::BackendRenderTarget.
