Enum masonry::text_helpers::ImeChangeSignal
source · #[non_exhaustive]pub enum ImeChangeSignal {
SelectionChanged,
LayoutChanged,
Reset,
}
Expand description
An event representing an application-initiated change in [InputHandler
]
state.
When we change state that may have previously been retrieved from an
[InputHandler
], we notify the platform so that it can invalidate any
data if necessary.
Variants (Non-exhaustive)§
This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
SelectionChanged
Indicates the value returned by InputHandler::selection
may have changed.
LayoutChanged
Indicates the values returned by one or more of these methods may have changed:
InputHandler::hit_test_point
InputHandler::line_range
InputHandler::bounding_box
InputHandler::slice_bounding_box
Reset
Indicates any value returned from any InputHandler
method may have changed.
