Member Function Documentation

clearScreen()

void tgui::BackendRenderTargetRaylib::clearScreen ( )

overridevirtual

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

Implements tgui::BackendRenderTarget.

drawGui()

void tgui::BackendRenderTargetRaylib::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

Warning

ScissorMode will be overwritten and EndScissorMode is called at the end of the function.

BlendMode will be overwritten and EndBlendMode is called at the end of the function.

Backface culling will be overwritten and rlEnableBackfaceCulling is called at the end of the function.

Implements tgui::BackendRenderTarget.

drawVertexArray()

void tgui::BackendRenderTargetRaylib::drawVertexArray ( const RenderStates & states, const Vertex * vertices, std::size_t vertexCount, const unsigned 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.

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.

setClearColor()

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

overridevirtual

Select the color that will be used by clearScreen.

Parameters

color

Background color of the window

Implements tgui::BackendRenderTarget.

setView()

void tgui::BackendRenderTargetRaylib::setView ( FloatRect view, FloatRect viewport, Vector2f targetSize )

overridevirtual

Informs the render target about which part of the window is used for rendering.

Parameters

view	Defines which part of the gui is being shown
viewport	Defines which part of the window is being rendered to
targetSize	Size of the window

Reimplemented from tgui::BackendRenderTarget.

updateClipping()

void tgui::BackendRenderTargetRaylib::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.
