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
:width-chars
and Entry
:max-width-chars
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.
Using a GtkSpinButton to get an integer
C code
// Provides a function to retrieve an integer value from a GtkSpinButton // and creates a spin button to model percentage values. gint grab_int_value (GtkSpinButton *button, gpointer user_data) { return gtk_spin_button_get_value_as_int (button); } void create_integer_spin_button (void) { GtkWidget *window, *button; GtkAdjustment *adjustment; adjustment = gtk_adjustment_new (50.0, 0.0, 100.0, 1.0, 5.0, 0.0); window = gtk_window_new (GTK_WINDOW_TOPLEVEL); gtk_container_set_border_width (GTK_CONTAINER (window), 5); // creates the spinbutton, with no decimal places button = gtk_spin_button_new (adjustment, 1.0, 0); gtk_container_add (GTK_CONTAINER (window), button); gtk_widget_show_all (window); }
Using a GtkSpinButton to get a floating point value
C code
// Provides a function to retrieve a floating point value from a // GtkSpinButton, and creates a high precision spin button. gfloat grab_float_value (GtkSpinButton *button, gpointer user_data) { return gtk_spin_button_get_value (button); } void create_floating_spin_button (void) { GtkWidget *window, *button; GtkAdjustment *adjustment; adjustment = gtk_adjustment_new (2.500, 0.0, 5.0, 0.001, 0.1, 0.0); window = gtk_window_new (GTK_WINDOW_TOPLEVEL); gtk_container_set_border_width (GTK_CONTAINER (window), 5); // creates the spinbutton, with three decimal places button = gtk_spin_button_new (adjustment, 0.001, 3); gtk_container_add (GTK_CONTAINER (window), button); gtk_widget_show_all (window); }

This is a convenience constructor that allows creation of a numeric
SpinButton
without manually creating an adjustment. The value is
initially set to the minimum value and a page increment of 10 * step
is the default. The precision of the spin button is equivalent to the
precision of step
.
Note that the way in which the precision is derived works best if step
is a power of ten. If the resulting precision is not suitable for your
needs, use spinButtonSetDigits
to correct it.

type C_SpinButtonOutputCallback = Ptr () -> Ptr () -> IO CInt Source #
Type for the callback on the (unwrapped) C side.
type SpinButtonOutputCallback Source #
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 -> SpinButtonOutputCallback -> m SignalHandlerId Source #
Connect a signal handler for the “output

When overloading is enabled, this is equivalent to
after
spinButton #output callback

Wrap the callback into a GClosure
.
mk_SpinButtonOutputCallback :: C_SpinButtonOutputCallback -> IO (FunPtr C_SpinButtonOutputCallback) Source #
Generate a function pointer callable from C code, from a C_SpinButtonOutputCallback

onSpinButtonOutput :: (IsSpinButton a, MonadIO m) => a -> SpinButtonOutputCallback -> m SignalHandlerId Source #
Connect a signal handler for the “output
” signal, to be run before the default handler.

valueChanged
type C_SpinButtonValueChangedCallback = Ptr () -> Ptr () -> IO () Source #
Type for the callback on the (unwrapped) C side.
type SpinButtonValueChangedCallback = IO () Source #
The ::value-changed signal is emitted when the value represented by
spinbutton
changes. Also see the SpinButton
::output
signal.
