Walk over the direct children of this element. A gui element that composites other gui elements should override this method. By default, the initial element is returned without change.

foldRecursive

fun <T : Any> foldRecursive(initial: T, @NotNull visitor: @NotNull BiFunction<@NotNull GuiComponent, T, T>): T

Walk the scene tree of this gui element, including children of children. By default, the visitor is called with only this element.

getHeight

open override fun getHeight(): Int

Get the requested y size for this element. This is opposed to the actual size given in the context. Giving this element less space than this may result in misaligned or overlapping rendering.

getWidth

open override fun getWidth(): Int

Get the requested x size for this element. This is opposed to the actual size given in the context. Giving this element less space than this may result in misaligned or overlapping rendering.

isFocused

open fun isFocused(): Boolean

Test if this element is focused.

isInFocus

open fun isInFocus(): Boolean

Test if this element is focused, or has a focused child.

keyboardEvent

open override fun keyboardEvent(event: KeyboardEvent, context: GuiImmediateContext): Boolean

Called by the parent renderer.

mouseEvent

open override fun mouseEvent(mouseEvent: MouseEvent, context: GuiImmediateContext): Boolean

Called by the parent renderer.

onGainedFocus

open fun onGainedFocus()

This method is called by the gui context when an element gains focus. This does only get called if this element specifically is being focused.

onLostFocus

open fun onLostFocus()

This method is called by the gui context when an element loses focus. This does only get called if this element specifically was focused.

render

open override fun render(context: GuiImmediateContext)

Called by the parent renderer. The GL matrix stack is pre-transformed, so rendering can begin at (0, 0) and should not render beyond what the context says is available.

requestFocus

open fun requestFocus()

Call this method to request focus in the current gui context.

setContext

open fun setContext(context: GuiContext)

setFocus

open fun setFocus(shouldFocus: Boolean)

Focuses or blurs this element depending on shouldFocus
