std::shared_ptr<Window> add ( const std::shared_ptr< Window > & window )

Adds a UI Window to the list of managed windows.

Parameters

window The window to add.

Returns: Shared pointer to the added window.

std::shared_ptr<Window> create ( const Rect & rect )

inline

Creates and adds a UI Window to the list of managed windows.

Parameters

rect	The rectangle (position and size) of the new window.

Returns: Shared pointer to the created window.

void drawFrame ( )

Draws one frame of the UI.

float getAspectRatio ( ) const

inline

Returns the aspect ratio of the managed rendering window.

std::shared_ptr<Font> getDefaultFont ( ) const

inline

Returns the default font loaded at creation.

float getDefaultFontScale ( ) const

inline

Returns the default font scale.

Style& getDefaultStyle ( ) const

inline

Returns the default style applied to the windows that do not set their own.

const auto& getModalWindow ( ) const

inline

Returns the Window blocking the input events of all the other Windows or nullptr.

Vector2DRenderer& getRenderer ( )

inline

Returns the 2D renderer used by the manager.

RenderingWindow& getRenderingWindow ( ) const

inline

Returns the rendering window the managed windows are displayed in.

float getResizeDelta ( ) const

inline

Returns the resize delta for window resizing.

bool onInput ( const InputEvent & inputEvent )

Handles an input event.

Parameters

inputEvent The input event to process.

Returns: True if the event was handled by the UI, false otherwise.

void remove ( const std::shared_ptr< Window > & window )

Removes a UI Window from the list of managed windows.

The Window will be removed at the start of the next frame.

void setDefaultFont ( std::shared_ptr< Font > & font )

Sets the default font scale

void setDefaultFontScale ( float fontScale )

Sets the default font scale

void setDefaultStyle ( const std::shared_ptr< Style > & style )

Sets the default style applied to the windows that do not set their own.

The widgets already attached keep the UIResource built by the previous style : the resource strings are shared by the built-in styles, but the colors baked in the resource strings of the composite widgets are not updated. Rebuild the windows to apply the new style everywhere.

Parameters

style The new default style, ignored when null.

void setEnableWindowResizing ( const bool enable )

inline
