Constructor & Destructor Documentation

◆ Canvas()

tgui::Canvas::Canvas ( const Layout2d size = {"100%", "100%"})

Default constructor.

Parameters
sizeSize of the canvas

Member Function Documentation

◆ canGainFocus()

bool tgui::Canvas::canGainFocus ( ) const
overridevirtual

Returns whether the widget can gain focus.

Returns
Can the widget be focused?

This function returns false for Canvas widgets.

Reimplemented from tgui::Widget.

◆ clear()

void tgui::Canvas::clear ( Color  color = Color::Black)

Clears the entire canvas with a single color.

This function is usually called once every frame, to clear the previous contents of the canvas.

Parameters
colorFill color to use to clear the canvas

◆ clone()

Widget::Ptr tgui::Canvas::clone ( ) const
inlineoverrideprotectedvirtual

Makes a copy of the widget if you don't know its exact type.

This function should only be used when you don't know the type of the widget. If you know what kind of widget you are copying, you should use the copy function.

Returns
Copy of the widget

Implements tgui::Widget.

◆ copy()

static Canvas::Ptr tgui::Canvas::copy ( Canvas::ConstPtr  canvas)
static

Makes a copy of another canvas.

Parameters
canvasThe other canvas
Returns
The new canvas

◆ create()

static Canvas::Ptr tgui::Canvas::create ( Layout2d  size = {"100%", "100%"})
static

Creates a new canvas widget.

Parameters
sizeSize of the canvas
Returns
The new canvas

◆ display()

void tgui::Canvas::display ( )

Updates the contents of the canvas.

This function updates the canvas with what has been drawn so far. Like for windows, calling this function is mandatory at the end of rendering. Not calling it may leave the texture in an undefined state.

◆ draw() [1/4]

void tgui::Canvas::draw ( const sf::Drawable &  drawable,
const sf::RenderStates &  states = sf::RenderStates::Default 
)

Draws a drawable object to the canvas.

Parameters
drawableObject to draw
statesRender states to use for drawing

◆ draw() [2/4]

void tgui::Canvas::draw ( const sf::Vertex *  vertices,
std::size_t  vertexCount,
sf::PrimitiveType  type,
const sf::RenderStates &  states = sf::RenderStates::Default 
)

Draws primitives defined by an array of vertices.

Parameters
verticesPointer to the vertices
vertexCountNumber of vertices in the array
typeType of primitives to draw
statesRender states to use for drawing

◆ draw() [3/4]

void tgui::Canvas::draw ( const tgui::Sprite sprite,
const sf::RenderStates &  states = sf::RenderStates::Default 
)

Draws a TGUI sprite to the canvas.

Parameters
spriteSprite to draw
statesRender states to use for drawing

◆ draw() [4/4]

void tgui::Canvas::draw ( sf::RenderTarget &  target,
sf::RenderStates  states 
) const
overridevirtual

Draw the widget to a render target.

Parameters
targetRender target to draw to
statesCurrent render states

Implements tgui::Widget.

◆ getDefaultView()

const sf::View& tgui::Canvas::getDefaultView ( ) const

Get the default view of the canvas.

The default view has the same size as the canvas.

Returns
The default view of the canvas

◆ getRenderTexture()

sf::RenderTexture& tgui::Canvas::getRenderTexture ( )
inline

Access the internal render texture that the canvas widget uses to draw on.

Returns
Reference to the internal render texture
Warning
Don't call the create function on the returned render texture.

◆ getView()

const sf::View& tgui::Canvas::getView ( ) const

Get the view currently in use in the canvas.

Returns
The view object that is currently used

◆ getViewport()

IntRect tgui::Canvas::getViewport ( ) const

Get the viewport of the currently applied view, applied to this canvas.

The viewport is defined in the view as a ratio, this function simply applies this ratio to the current dimensions of the canvas to calculate the pixels rectangle that the viewport actually covers in the canvas.

Returns
Viewport rectangle, expressed in pixels

◆ rendererChanged()

void tgui::Canvas::rendererChanged ( const String property)
overrideprotectedvirtual

Function called when one of the properties of the renderer is changed.

Parameters
propertyLowercase name of the property that was changed

Reimplemented from tgui::Widget.

◆ setSize() [1/3]

virtual void tgui::Widget::setSize

Changes the size of the widget.

Parameters
sizeSize of the widget

Usage examples:

// Give the widget an exact size
widget->setSize({40, 30});
// Give the widget a size relative to the size of its parent
widget->setSize({"20%", "5%"});
// Make the widget 50 pixels higher than some other widget and automatically resize it when the other widget resizes
widget->setSize({200, tgui::bindHeight(otherWidget) + 50});

◆ setSize() [2/3]

void tgui::Canvas::setSize ( const Layout2d size)
overridevirtual

Changes the size of the widget.

Parameters
sizeThe new size of the widget

Reimplemented from tgui::Widget.

◆ setSize() [3/3]

void tgui::Widget::setSize
inline

Changes the size of the widget.

Parameters
widthWidth of the widget
heightHeight of the widget
Warning
This setSize overload must never be used from internal TGUI code or by custom widget implementations

◆ setView()

void tgui::Canvas::setView ( const sf::View &  view)

Change the current active view.

The view is like a 2D camera, it controls which part of the 2D scene is visible, and how it is viewed in the canvas. The new view will affect everything that is drawn, until another view is set. The canvas keeps its own copy of the view, so it is not necessary to keep the original one alive after calling this function. To restore the original view of the target, you can pass the result of getDefaultView() to this function.

Warning
This view is reset when the size of the canvas is changed.
Parameters
viewNew view to use

The documentation for this class was generated from the following file:
TGUI_API Layout bindHeight(Gui &gui)
Bind to the height of the gui view.
