FabricMinecraftScreen

class FabricMinecraftScreen : Screen, AutoCloseable, RuntimeUiDiagnosticsOwner, FabricMinecraftInputReset(source)

Fabric client screen backed by one common Minecraft UI host.

The host is created by transferring the one-shot ScreenDefinition and is confined to the Minecraft client thread. Added and removed screen callbacks attach and detach the retained tree; removal is transient and never closes the screen. Terminal close releases the host and every transient dynamic texture layer. A caller that permanently abandons a removed or never-presented instance must close it on the client thread. The optional parent is retained for navigation but is never owned or closed. Rendering rasterizes portable command runs through the headless adapter and submits synchronized ItemStack commands through Minecraft's native GUI renderer at their exact display-list positions. Mouse coordinates are floored after finite and integer-range checks. Horizontal scroll is forwarded unchanged, while vertical scroll is negated to match the common increasing-y contract.

Functions

added

open override fun added()

Attaches the common retained tree when Minecraft adds this screen.

afterKeyboardAction

open fun afterKeyboardAction()

afterMouseAction

open fun afterMouseAction()

afterMouseMove

open fun afterMouseMove()

canInterruptWithAnotherScreen

open fun canInterruptWithAnotherScreen(): Boolean

captureCanvasFrame

fun captureCanvasFrame(): List<DrawCommand>

Captures the last complete presentation from immutable CPU images and exact native-generation snapshots only.

charTyped

open override fun charTyped(event: CharacterEvent): Boolean

Delivers one committed Unicode character to the focused retained component before inherited screen behavior.

children

open fun children(): List<out GuiEventListener?>?

clearFocus

open fun clearFocus()

open override fun close()

Releases host and texture ownership exactly once. A close requested synchronously from a common frame or input callback is deferred until that operation exits on the same client thread. This method does not navigate; a displayed screen must be replaced by Minecraft or closed through onClose, while a later onClose may still perform its one parent-navigation attempt.

fillCrashDetails

open fun fillCrashDetails(crashReport: CrashReport?)

getBorderForArrowNavigation

open fun getBorderForArrowNavigation(screenDirection: ScreenDirection?): ScreenRectangle?

getChildAt

open fun getChildAt(d: Double, e: Double): Optional<GuiEventListener?>?

handleDelayedNarration

open fun handleDelayedNarration()

init

fun init(i: Int, j: Int)

isMouseOver

open fun isMouseOver(d: Double, e: Double): Boolean

isPauseScreen

open override fun isPauseScreen(): Boolean

Reports whether this screen pauses the game according to its transferred definition.

keyPressed

open override fun keyPressed(event: KeyEvent): Boolean

Preserves Minecraft's screen-level Escape handling before delivering other key presses to the focused retained component and then inherited focus-navigation behavior.

keyReleased

open override fun keyReleased(event: KeyEvent): Boolean

Delivers a native key release to the focused retained component before inherited screen behavior.

mouseClicked

open override fun mouseClicked(event: MouseButtonEvent, doubleClick: Boolean): Boolean

Delivers a native mouse press to the common host.

mouseDragged

open override fun mouseDragged(event: MouseButtonEvent, deltaX: Double, deltaY: Double): Boolean

Delivers native movement while a mouse button is held as one typed common drag event.

mouseMoved

open override fun mouseMoved(mouseX: Double, mouseY: Double)

Delivers a finite mouse movement to the common host.

mouseReleased

open override fun mouseReleased(event: MouseButtonEvent): Boolean

Delivers a native mouse release to the common host.

mouseScrolled

open override fun mouseScrolled(mouseX: Double, mouseY: Double, deltaX: Double, deltaY: Double): Boolean

Delivers native scroll displacement after mapping vertical sign into the common coordinate contract.

nextFocusPath

open fun nextFocusPath(focusNavigationEvent: FocusNavigationEvent?): @Nullable ComponentPath?

onClose

open override fun onClose()

Closes the host and always navigates to the transferred parent screen.

onFilesDrop

open fun onFilesDrop(list: List<Path?>?)

removed

open override fun removed()

Detaches the common retained tree while retaining it for a later add callback. Detached screens release their prepared display list and dynamic textures so a parent screen cannot retain presentation-only data while hidden.
