Interface IUIWindow2

interface IUIWindow2

Extends IUIWindow This interface extends IUIWindow to provide dynamic window configuration capabilities such as window size, position, and behavior. All methods of this interface like IUIWindow must be called on the UI thread.

​

Methods

​

setPosition()

void setPosition(com.amazon.kepler.uitoolkit.graphics.Point point)

Sets the position of the window on screen. The position is specified in screen coordinates, where (0,0) represents the top-left corner of the screen. If IUIWindow2::setConstrainedToScreen is enabled, the position will be adjusted to ensure the window remains fully visible within the screen boundaries. Positions that would push the window out of bounds will be clamped to the nearest valid position.

​

Parameters

point

com.amazon.kepler.uitoolkit.graphics.Point — Required The new position for the window in screen coordinates.

---

​

setSize()

void setSize(com.amazon.kepler.uitoolkit.graphics.Size size)

Sets the size of the window. The size represents the width and height of the window’s content area.

​

Parameters

size

com.amazon.kepler.uitoolkit.graphics.Size — Required The size for the window to be set.

---

​

setResponsive()

void setResponsive(bool isResponsive)

Sets whether the window should be responsive to input events like key and touch. When set to true, the window will receive and process user input events such as keyboard input, touch gestures, and mouse interactions. When set to false, the window becomes non-interactive and all input events will pass through to windows beneath it.

​

Parameters

isResponsive

bool — Required If true, the window would process and respond to input events. If false, the window would become non-interactive.

---

​

setTransparent()

void setTransparent(bool isTransparent)

Sets whether the window should be transparent. When set to true, the window background becomes transparent, allowing content from windows beneath it to be visible. When set to false, the window has an opaque background.

​

Parameters

isTransparent

bool — Required If true, the window would be transparent. If false, the window would be opaque.

---

​

setConstrainedToScreen()

void setConstrainedToScreen(bool isConstrained)

Sets whether the window should be constrained to the screen boundaries. When set as true, the window will be constrained to remain fully visible within the screen bounds. The window cannot be moved or resized such that it extends beyond the screen edges. When set as false, the window can be positioned anywhere, including partially or completely off-screen. By default it is set as false

​

Parameters

isConstrained

bool — Required If true, the window would be constrained to screen, false otherwise.

---

​

setDraggable()

void setDraggable(bool isDraggable)

Sets whether the window can be dragged by the user. By default it is set as false

​

Parameters

isDraggable

bool — Required If true, the window is draggable, false otherwise.

---

​

getPosition()

com.amazon.kepler.uitoolkit.graphics.Point getPosition()

Gets the current position of the window on screen.

​

Returns

com.amazon.kepler.uitoolkit.graphics.Point The current position of the window in screen coordinates.

---

​

getSize()

com.amazon.kepler.uitoolkit.graphics.Size getSize()

Gets the current size of the window.

​

Returns

com.amazon.kepler.uitoolkit.graphics.Size The current size of the window.

---

​

isTransparent()

bool isTransparent()

Gets whether the window is transparent.

​

Returns
