Returns

Subscribable<boolean>

Methods

activateEditing()

activateEditing(isSelectionPerSlot): void

Defined in: workingtitle-instruments-g3000/html_ui/GTC/Components/FrequencyInput/FrequencyInput.tsx:280

Activates editing for this input.

Parameters

Parameter	Type	Description
isSelectionPerSlot	boolean	Whether cursor selection should be initialized to per-slot mode. If false, cursor selection will be initialized to per-character mode instead.

Returns

void

Throws

Error if this input is not initialized.

---

backspace()

backspace(): void

Defined in: workingtitle-instruments-g3000/html_ui/GTC/Components/FrequencyInput/FrequencyInput.tsx:407

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.

Returns

void

Throws

Error if this input is not initialized.

---

changeSlotValue()

changeSlotValue(direction): void

Defined in: workingtitle-instruments-g3000/html_ui/GTC/Components/FrequencyInput/FrequencyInput.tsx:327

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

Parameter	Type	Description
direction	-1 | 1	The direction in which to change the slot value (1 = increment, -1 = decrement).

Returns

void

Throws

Error if this input is not initialized.
