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.

setFrequency()
setFrequency(
freq
):number
Defined in: workingtitle-instruments-g3000/html_ui/GTC/Components/FrequencyInput/FrequencyInput.tsx:253
Sets the frequency value of this slot. As part of the operation, all of this slot's characters will be set to non-null representations of the new slot value, if possible. The frequency value of this slot after the operation is complete may differ from the requested value depending on whether the requested value can be accurately represented by this slot.
Parameters
Parameter | Type | Description |
---|---|---|
freq | number | The new frequency value, in hertz. |
Returns
number
The frequency value of this input after the operation is complete.
Throws
Error if this input is not initialized.

Defined in: workingtitle-instruments-g3000/html_ui/GTC/Components/FrequencyInput/FrequencyInput.tsx:345
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. 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
Parameter | Type | Description |
---|---|---|
value | string | The value to set. |
Returns
void
Throws
