Methods

activateEditing()

activateEditing(isSelectionPerSlot): void

Defined in: src/workingtitle-instruments-g3x-touch/html_ui/Shared/Components/CharInput/CharInput.tsx:131

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: src/workingtitle-instruments-g3x-touch/html_ui/Shared/Components/CharInput/CharInput.tsx:247

Removes the character at the cursor's current position and shifts 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, eraseCharsToRightOnEdit): void

Defined in: src/workingtitle-instruments-g3x-touch/html_ui/Shared/Components/CharInput/CharInput.tsx:200

Increments or decrements the value of the slot currently selected by the cursor. If editing is not active, then 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, then this method does nothing.

Parameters

Parameter	Type	Default value	Description
direction	-1 | 1	undefined	The direction in which to change the slot value (1 = increment, -1 = decrement).
eraseCharsToRightOnEdit	boolean	false	Whether to erase (set to null) all characters to the right of the edited character. Defaults to false.

Returns

void

Throws

Error if this input is not initialized.
