Structs
A view’s bounding box, described in the view’s own coordinate system.
Concretely, |AlignedExtent| describes the minimal and maximal points of a
view’s bounding box, which is rectangular and axis-aligned.
Geometric data of a view.
A view bounding box, described in another view’s coordinate system.
Concretely, |RotatableExtent| describes the origin, size, and rotation angle
about the origin, for a view’s bounding box.
Data for a particular view: identifier, position, and children.
A description of the context view and its descendant views, if any.
A Stream of incoming requests for ViewTreeWatcher
Response for fuchsia.ui.observation.geometry.ViewTreeWatcher.Watch.
Enums
A method of obtaining view tree snapshots for a particular view, the “context
view”, and its child views, if any. The returned data is a sequence of
snapshots during the period of observation, which starts at the client’s
prior Watch() call’s [
epoch_end] (or zx.time 0), and ending at the
current [epoch_end]. The timebase is ZX_CLOCK_MONOTONIC.Constants
The maximum number of
ViewTreeSnapshots a client can expect in a Watch call’s
response. The number of ViewTreeSnapshots can be less than BUFFER_SIZE when
the size of a Watch call’s response exceeds the limit of a FIDL channel.The maximum number of
ViewDescriptors a client can expect in a
ViewTreeSnapshot.
