Member Function Documentation

createText()

virtual std::shared_ptr< BackendText > tgui::BackendRenderer::createText ( )

inlinevirtual

Creates a new empty text object.

Returns

Shared pointer to a new text object

createTexture()

virtual std::shared_ptr< BackendTexture > tgui::BackendRenderer::createTexture ( )

pure virtual

Creates a new empty texture object.

Returns

Shared pointer to a new texture object

Implemented in tgui::BackendRendererGLES2, tgui::BackendRendererOpenGL3, tgui::BackendRendererSDL, and tgui::BackendRendererSFML.

getMaximumTextureSize()

virtual unsigned int tgui::BackendRenderer::getMaximumTextureSize ( )

pure virtual

Get the maximum allowed texture size.

Returns

Maximum width and height that you should try to use in a single texture

This maximum size is defined by the graphics driver. Most likely this will return 8192 or 16384.
