GI.Gtk.Objects.SpinButton

A SpinButton is an ideal way to allow the user to set the value of some attribute. Rather than having to directly type a number into a Entry, GtkSpinButton allows the user to click on one of two arrows to increment or decrement the displayed value. A value can still be typed in, with the bonus that it can be checked to ensure it is in a given range.

The main properties of a GtkSpinButton are through an adjustment. See the Adjustment section for more details about an adjustment's properties. Note that GtkSpinButton will by default make its entry large enough to accomodate the lower and upper bounds of the adjustment, which can lead to surprising results. Best practice is to set both the Entry:widthChars and Entry:maxWidthChars poperties to the desired number of characters to display in the entry.

GtkSpinButtons main CSS node has the name spinbutton. It creates subnodes for the entry and the two buttons, with these names. The button nodes have the style classes .up and .down. The GtkEntry subnodes (if present) are put below the entry node. The orientation of the spin button is reflected in the .vertical or .horizontal style class on the main node.

Signals

changeValue

type SpinButtonChangeValueCallback

Arguments

 = ScrollType

scroll: a ScrollType to specify the speed and amount of change

-> IO ()

The changeValue signal is a [keybinding signal][GtkBindingSignal] which gets emitted when the user initiates a value change.

Applications should not connect to it, but may emit it with g_signal_emit_by_name() if they need to control the cursor programmatically.

The default bindings for this signal are Up/Down and PageUp and/PageDown.

afterSpinButtonChangeValue :: (IsSpinButton a, MonadIO m) => a -> ((?self :: a) => SpinButtonChangeValueCallback) -> m SignalHandlerId

Connect a signal handler for the changeValue signal, to be run after the default handler. When overloading is enabled, this is equivalent to

after spinButton #changeValue callback

By default the object invoking the signal is not passed to the callback. If you need to access it, you can use the implit ?self parameter. Note that this requires activating the ImplicitParams GHC extension.

onSpinButtonChangeValue :: (IsSpinButton a, MonadIO m) => a -> ((?self :: a) => SpinButtonChangeValueCallback) -> m SignalHandlerId

Connect a signal handler for the changeValue signal, to be run before the default handler. When overloading is enabled, this is equivalent to

on spinButton #changeValue callback

input

type SpinButtonInputCallback

Arguments

 = IO (Int32, Double)

Returns: True for a successful conversion, False if the input was not handled, and INPUT_ERROR if the conversion failed.

The input signal can be used to influence the conversion of the users input into a double value. The signal handler is expected to use entryGetText to retrieve the text of the entry and set newValue to the new value.

The default conversion uses strtod.

afterSpinButtonInput :: (IsSpinButton a, MonadIO m) => a -> ((?self :: a) => SpinButtonInputCallback) -> m SignalHandlerId

Connect a signal handler for the input signal, to be run after the default handler. When overloading is enabled, this is equivalent to

after spinButton #input callback

By default the object invoking the signal is not passed to the callback. If you need to access it, you can use the implit ?self parameter. Note that this requires activating the ImplicitParams GHC extension.

onSpinButtonInput :: (IsSpinButton a, MonadIO m) => a -> ((?self :: a) => SpinButtonInputCallback) -> m SignalHandlerId

Connect a signal handler for the input signal, to be run before the default handler. When overloading is enabled, this is equivalent to

on spinButton #input callback

output

type SpinButtonOutputCallback

Arguments

 = IO Bool

Returns: True if the value has been displayed

The output signal can be used to change to formatting of the value that is displayed in the spin buttons entry.

C code

// show leading zeros
static gboolean
on_output (GtkSpinButton *spin,
           gpointer       data)
{
   GtkAdjustment *adjustment;
   gchar *text;
   int value;

   adjustment = gtk_spin_button_get_adjustment (spin);
   value = (int)gtk_adjustment_get_value (adjustment);
   text = g_strdup_printf ("%02d", value);
   gtk_entry_set_text (GTK_ENTRY (spin), text);
   g_free (text);

   return TRUE;
}

afterSpinButtonOutput :: (IsSpinButton a, MonadIO m) => a -> ((?self :: a) => SpinButtonOutputCallback) -> m SignalHandlerId

Connect a signal handler for the output signal, to be run after the default handler. When overloading is enabled, this is equivalent to

after spinButton #output callback

By default the object invoking the signal is not passed to the callback. If you need to access it, you can use the implit ?self parameter. Note that this requires activating the ImplicitParams GHC extension.

onSpinButtonOutput :: (IsSpinButton a, MonadIO m) => a -> ((?self :: a) => SpinButtonOutputCallback) -> m SignalHandlerId

Connect a signal handler for the output signal, to be run before the default handler. When overloading is enabled, this is equivalent to

on spinButton #output callback

valueChanged

type SpinButtonValueChangedCallback = IO ()

The valueChanged signal is emitted when the value represented by spinbutton changes. Also see the SpinButton::output signal.

afterSpinButtonValueChanged :: (IsSpinButton a, MonadIO m) => a -> ((?self :: a) => SpinButtonValueChangedCallback) -> m SignalHandlerId

Connect a signal handler for the valueChanged signal, to be run after the default handler. When overloading is enabled, this is equivalent to

after spinButton #valueChanged callback

By default the object invoking the signal is not passed to the callback. If you need to access it, you can use the implit ?self parameter. Note that this requires activating the ImplicitParams GHC extension.

onSpinButtonValueChanged :: (IsSpinButton a, MonadIO m) => a -> ((?self :: a) => SpinButtonValueChangedCallback) -> m SignalHandlerId

Connect a signal handler for the valueChanged signal, to be run before the default handler. When overloading is enabled, this is equivalent to

on spinButton #valueChanged callback

wrapped

type SpinButtonWrappedCallback = IO ()

The wrapped signal is emitted right after the spinbutton wraps from its maximum to minimum value or vice-versa.

Since: 2.10

afterSpinButtonWrapped :: (IsSpinButton a, MonadIO m) => a -> ((?self :: a) => SpinButtonWrappedCallback) -> m SignalHandlerId

Connect a signal handler for the wrapped signal, to be run after the default handler. When overloading is enabled, this is equivalent to

after spinButton #wrapped callback

By default the object invoking the signal is not passed to the callback. If you need to access it, you can use the implit ?self parameter. Note that this requires activating the ImplicitParams GHC extension.

onSpinButtonWrapped :: (IsSpinButton a, MonadIO m) => a -> ((?self :: a) => SpinButtonWrappedCallback) -> m SignalHandlerId

Connect a signal handler for the wrapped signal, to be run before the default handler. When overloading is enabled, this is equivalent to

on spinButton #wrapped callback
