class ViewParameters

Defined at line 1032 of file fidling/gen/sdk/fidl/fuchsia.ui.pointer/fuchsia.ui.pointer/cpp/fidl/fuchsia.ui.pointer/cpp/natural_types.h

The parameters of the associated view and viewport, sufficient to correctly

interpret the position and scale of pointer events dispatched to this view.

Ordering. These parameters arrive over the same channel as pointer events,

to provide synchronous context for interpreting the position of pointer

events in the view's local coordinate system.

Inter-protocol redundancy. Some of these parameters may also be sent over an

independent channel dedicated to view control; the client is responsible for

correct use of asynchronously received parameters.

TODO(https://fxbug.dev/42162292): Rename viewport, it is used in Flatland.

const ::fuchsia_ui_pointer::Rectangle & view ()

The view's area of content, placed in the coordinate system of the view.

The rectangle is defined by the parent view's setup of clipping on this

view.

::fuchsia_ui_pointer::Rectangle & view ()

The view's area of content, placed in the coordinate system of the view.

The rectangle is defined by the parent view's setup of clipping on this

view.

ViewParameters & view (::fuchsia_ui_pointer::Rectangle value)

The view's area of content, placed in the coordinate system of the view.

The rectangle is defined by the parent view's setup of clipping on this

view.

const ::fuchsia_ui_pointer::Rectangle & viewport ()

The viewport's area of interaction, placed in an independent coordinate

system.

A pointer event's position is defined in the coordinate system of this

viewport.

A change in viewport extents means the region for pointer interaction

has itself moved, or changed in size, or both.

::fuchsia_ui_pointer::Rectangle & viewport ()

The viewport's area of interaction, placed in an independent coordinate

system.

A pointer event's position is defined in the coordinate system of this

viewport.

A change in viewport extents means the region for pointer interaction

has itself moved, or changed in size, or both.

ViewParameters & viewport (::fuchsia_ui_pointer::Rectangle value)

The viewport's area of interaction, placed in an independent coordinate

system.

A pointer event's position is defined in the coordinate system of this

viewport.

A change in viewport extents means the region for pointer interaction

has itself moved, or changed in size, or both.

const ::std::array<float, 9> & viewport_to_view_transform ()

The transform matrix that relates a point's position in the viewport's

coordinate system to its position in the view's coordinate system.

::std::array<float, 9> & viewport_to_view_transform ()

The transform matrix that relates a point's position in the viewport's

coordinate system to its position in the view's coordinate system.

ViewParameters & viewport_to_view_transform (::std::array<float, 9> value)

The transform matrix that relates a point's position in the viewport's

coordinate system to its position in the view's coordinate system.
