Set the overflow inset rect values which indicate the extensions to the boundaries of currentview that wraps all of its children views
-
getOverflowInset
Rect getOverflowInset()
Get the overflow inset rect values which indicate the extensions to the boundaries of currentview that wraps all of its children views
-
requestChildFocus
void requestChildFocus(View child, View focused)
Since ReactHorizontalScrollView handles layout changes on JS side, it does not callsuper.onlayout due to which mIsLayoutDirty flag in HorizontalScrollView remains true andprevents scrolling to child when requestChildFocus is called. Overriding this method andscrolling to child without checking any layout dirty flag. This will fix focus navigation issuefor KeyEvents which are not handled in HorizontalScrollView, for example: KEYCODE_TAB.

updateClippingRect
void updateClippingRect()
Notify view that clipping area may have changed and it should recalculate the list of childrenthat should be attached/detached. This method should be called only when property
{@code * removeClippedSubviews}
is set to{@code true}
on a view.CAUTION: Views are responsible for calling updateClippingRect on it's children.This should happen if child implement ReactClippingViewGroup, return true from and clipping rect change of the current view may affect clippingrect of this child.
-
getClippingRect
void getClippingRect(Rect outClippingRect)
Get rectangular bounds to which view is currently clipped to. Called only on views that has set
{@code removeCLippedSubviews}
property value to{@code true}
.- Parameters:
outClippingRect
- output clipping rect should be written to this object.
-

reactSmoothScrollTo
void reactSmoothScrollTo(int x, int y)
Calls `smoothScrollTo` and updates state.
`smoothScrollTo` changes `contentOffset` and we need to keep `contentOffset` in sync betweenscroll view and state. Calling raw `smoothScrollTo` doesn't update state.
-
scrollTo
void scrollTo(int x, int y)
Calls `super.scrollTo` and updates state.
`super.scrollTo` changes `contentOffset` and we need to keep `contentOffset` in sync betweenscroll view and state.
Note that while we can override scrollTo, we *cannot* override `smoothScrollTo` because itis final. See `reactSmoothScrollTo`.
