#include <TGUI/Backend/Renderer/SDL_Renderer/BackendRenderTargetSDL.hpp>
Public Member Functions | |
| BackendRenderTargetSDL (SDL_Renderer *renderer) | |
| Default constructor. | |
| void | setClearColor (const Color &color) override |
| Select the color that will be used by clearScreen. | |
| void | clearScreen () override |
| Clears the screen, called at the beginning of each frame when gui.mainLoop() is called. | |
| void | setView (FloatRect view, FloatRect viewport, Vector2f targetSize) override |
| Informs the render target about which part of the window is used for rendering. | |
| void | drawGui (const std::shared_ptr< RootContainer > &root) override |
| Draws the gui and all of its widgets. | |
| void | 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) override |
| Draws a vertex array. This is called by the other draw functions. | |

overridevirtual |
Clears the screen, called at the beginning of each frame when gui.mainLoop() is called.
Implements tgui::BackendRenderTarget.
|
overridevirtual |
Draws the gui and all of its widgets.
| root | Root container that holds all widgets in the gui |
Implements tgui::BackendRenderTarget.
|
overridevirtual |
Draws a vertex array. This is called by the other draw functions.
| 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.
|
overridevirtual |
Select the color that will be used by clearScreen.
| color | Background color of the window |
Implements tgui::BackendRenderTarget.
|
overridevirtual |
Informs the render target about which part of the window is used for rendering.
| 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.
|
overrideprotectedvirtual |
Called from addClippingLayer and removeClippingLayer to apply the clipping.
| 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.
