Public

static const String &GetGuiTypeName()

Returns type name of the GUI element used for finding GUI element styles.

void SetGradient(const T &colorGradient)

Color gradient to display.

T GetGradient() const

static GUIElementType *Create(const String &styleClass, const TInlineArray<GUIOption, 4> &options)

Creates a new GUI element.

styleClass: Style class that will be used for determining GUI element visuals from the current style sheet. If no class is provided, default style is determined based on GUI element type.
options: Additional options that control GUI element size and position. This will override options set in the style sheet.

Event<void ()> OnClicked

Triggered when the user clicks on the GUI element.

GUILogicalSize CalculateUnconstrainedOptimalSize() const override

Calculates the optimal size for the GUI element, ignoring size constraints.

const char *GetStyleSheetElement() const override

Returns the name of the GUI element type to be used for style lookup in the style sheet.

void UpdateRenderElements() override

Recreates the internal render elements.

Must be called before GetRenderElementVertexAndIndexData/FillBuffer if element is dirty. Marks the element as non dirty.

bool DoOnMouseEvent(const GUIMouseEvent &ev) override

Called when a mouse event is received on any GUI element the mouse is interacting with.

Return true if you have processed the event and don't want other elements to process it.

static HTexture GenerateGradientTexture(const T &gradient, u32 width, bool alpha = false)

Generates a texture from the provided color gradient value.

gradient: Gradient to generate the texture from.
width: Width of the texture in pixels. Height is always 1.
alpha: If true generate a texture representing the alpha values of the gradient (grayscale), otherwise generate a color texture.
