Interface IScrollableView3

interface IScrollableView3

Extends IScrollableView2 IScrollableView3 interface extends IScrollableView2 and defines new methods for scrollable components for controlling scrollbar fading, scrollbar visibility, texture caching, scroll inversion and scrolling functionality.

​

Methods

​

setScrollbarFadingEnabled()

void setScrollbarFadingEnabled(bool fadingEnabled)

Enables or disables scrollbar fading. This method controls the visibility behavior of the scrollbar. When fading is enabled, the scrollbar will automatically fade out after a period of inactivity, providing a cleaner visual experience. When fading is disabled, the scrollbar remains persistently visible at all times. Use this method to toggle between auto-hide and always-visible scrollbar modes based on your application’s UX requirements.

​

Parameters

fadingEnabled

bool — Required Set to true to enable fading behavior (auto-hide), or false for always visible scrollbar. The default value is true.

---

​

isScrollbarFadingEnabled()

bool isScrollbarFadingEnabled()

Checks whether the scrollbar fading is enabled. Returns whether the scrollbar will automatically fade out after a period of inactivity. When fading is enabled, the scrollbar auto-hides for a cleaner visual experience. When disabled, the scrollbar remains persistently visible.

​

Returns

bool true if scrollbar fading is enabled, false otherwise.

---

​

setScrollbarEnabled()

void setScrollbarEnabled(bool enabled)

Enables or disables the scrollbar. This method controls the visibility of the scrollbar. When enabled, the scrollbar will be displayed when scrolling. When disabled, the scrollbar will not be shown.

​

Parameters

enabled

bool — Required Set to true to enable the scrollbar, or false to disable it. The default value is true.

---

​

isScrollbarEnabled()

bool isScrollbarEnabled()

Checks whether the scrollbar is enabled. Returns whether the scrollbar is currently enabled and will be displayed during scrolling.

​

Returns

bool true if the scrollbar is enabled, false otherwise.

---

​

setTextureCacheEnabled()

void setTextureCacheEnabled(bool enabled)

Enables or disables texture cache. When enabled, the view’s rendered content is cached as a GPU texture, allowing the compositor to reuse it across scroll frames without re-rasterizing. This improves scroll rendering performance for views with complex or expensive content. It is disabled by default. Note: Enabling texture cache increases GPU memory usage. It should be enabled only on static content.

​

Parameters

enabled

bool — Required True to enable texture cache, false to disable.

---

​

isTextureCacheEnabled()

bool isTextureCacheEnabled()

Returns whether texture cache is enabled.

​

Returns

bool True if texture cache is enabled, false otherwise.

---

​

setInverted()

void setInverted(bool inverted)

Sets if the scroll direction should be inverted. This method controls whether the scroll direction is inverted along the configured axis. When inverted, scrolling behavior is reversed: dragging down scrolls up (for vertical), or dragging right scrolls left (for horizontal). This is useful for implementing right-to-left layouts or specialized UI patterns where inverted scrolling is desired. Note: Setting it to true will display the scroll view from the ending item.

​

Parameters

inverted

bool — Required True for inverting the axis, else false. The default value is false.

---

​

isInverted()

bool isInverted()

Checks if the scroll axis is inverted.

​

Returns

bool True if the axis is inverted, false otherwise.

---

​

setScrollEnabled()

void setScrollEnabled(bool enabled)

Enables or disables scrolling for the scrollable view. This method directly controls whether the scrollable view can be scrolled by the user. When disabled, all scroll interactions (touch, pointer, keyboard) are blocked.

​

Parameters

enabled

bool — Required True to enable scrolling, false to disable. The default value is true.

---

​

isScrollEnabled()

bool isScrollEnabled()

Checks if scrolling is enabled.

​

Returns

bool True if scrolling is enabled, false otherwise.
