Struct input_pipeline::modifier_handler::ModifierHandler

pub struct ModifierHandler {
    pub inspect_status: InputHandlerStatus,
    /* private fields */
}

Tracks modifier state and decorates passing events with the modifiers.

This handler should be installed as early as possible in the input pipeline, to ensure that all later stages have the modifiers and lock states available. This holds even for non-keyboard handlers, to allow handling Ctrl+Click events, for example.

One possible exception to this rule would be a hardware key rewriting handler for limited keyboards.

Fields

inspect_status: InputHandlerStatus

The inventory of this handler’s Inspect status.
