Class: CursorInput<M>

An input display with a scrolling cursor.

Each input has zero or more child slots of type CursorInputSlot (though to be practically useful, at least one slot is required). When editing is active, the input's cursor selects either one slot or one character (a slot may have more than one character) at a time. The input supports incrementing or decrementing the value of a selected slot, or directly setting/deleting the value of a selected character.

Each input is bound to a composite value. This value is computed from the values of the input's individual slots, and vice versa, so that changes in either will be reflected in the other.

Methods

activateEditing

activateEditing(isSelectionPerSlot, charToSet?): boolean

Activates editing for this input.

Parameters

NameTypeDescription
isSelectionPerSlotbooleanWhether cursor selection should be initialized to per-slot mode. If false, cursor selection will be initialized to per-character mode instead.
charToSet?null | stringThe value to set at the cursor's selected character position as the initial edit. If defined and the character position cannot accept the value, editing will not be activated. Ignored if isSelectionPerSlot is true.

Returns

boolean

Whether editing is active.

Throws

Error if this input is not initialized.

Defined in

workingtitle-instruments-g3000/html_ui/Pages/VCockpit/Instruments/NavSystems/WTG3000/GTC/Components/CursorInput/CursorInput.tsx:358


backspace

backspace(selectionPerSlot?): void

Removes the character at the cursor's current position. If backfill is allowed, this will also shift all non-empty characters to the left of the cursor's current position one position to the right. If backfill is not allowed, this will shift the cursor one position to the left after the character is removed.

Parameters

NameTypeDescription
selectionPerSlot?booleanThe selection per slot state to apply before carrying out the backspace operation. If not defined, the selection per slot state will remain unchanged from its current value.

Returns

void

Throws

Error if this input is not initialized.

Defined in

workingtitle-instruments-g3000/html_ui/Pages/VCockpit/Instruments/NavSystems/WTG3000/GTC/Components/CursorInput/CursorInput.tsx:724


changeSlotValue

changeSlotValue(direction): boolean

Increments or decrements the value of the slot currently selected by the cursor. If editing is not active, it will be activated instead of changing any slot value. If cursor selection is in per-character mode, it will be forced to per-slot mode. If the cursor is past the last slot, this method does nothing.

Parameters

NameTypeDescription
direction1 | -1The direction in which to change the slot value (1 = increment, -1 = decrement).

Returns

boolean

Whether the value of the slot was changed.

Throws

Error if this input is not initialized.

Defined in

deactivateEditing

deactivateEditing(): void

Deactivates editing for this input.

Returns

void

Throws

Error if this input is not initialized.

setSlotCharacterValue

setSlotCharacterValue(value): boolean

Sets the value of the slot character currently selected by the cursor. If editing is not active, it will be activated before setting the value (unless the selected character cannot accept the value, in which case the operation will be aborted). If cursor selection is in per-slot mode, it will be forced to per-character mode, and the first character of the slot will be selected before setting the value. If the cursor is past the last slot, this method does nothing.

Parameters

NameTypeDescription
valuestringThe value to set.

Returns

boolean

Whether the operation was accepted.

Throws

Error if this input is not initialized.

setValue

setValue(value): SubscribableType<M>

Sets the composite value of this input. As part of the operation, all of this input's child slots will have their values set according to this input's value digitizer, and all slot characters will be set to non-null representations of their slot's value, if possible. The composite value of this input after the operation is complete may differ from the requested value depending on whether the requested value can be accurately represented by this input.

Parameters

NameTypeDescription
valueSubscribableType<M>The new composite value.

Returns

SubscribableType<M>

The composite value of this input after the operation is complete.

Throws

Error if this input is not initialized.
