Memory-managed wrapper type.

Type class for types which can be safely cast to SpinButton, for instance with toSpinButton.

Cast to SpinButton, for types for which this is known to be safe. For general casts, use castTo.

Changes the properties of an existing spin button. The adjustment, climb rate, and number of decimal places are updated accordingly.

Get the adjustment associated with a SpinButton

Fetches the precision of spinButton. See spinButtonSetDigits.

Gets the current step and page the increments used by spinButton. See spinButtonSetIncrements.

Returns whether non-numeric text can be typed into the spin button. See spinButtonSetNumeric.

Gets the range allowed for spinButton. See spinButtonSetRange.

Returns whether the values are corrected to the nearest step. See spinButtonSetSnapToTicks.

Gets the update behavior of a spin button. See spinButtonSetUpdatePolicy.

Get the value in the spinButton.

Get the value spinButton represented as an integer.

Returns whether the spin button’s value wraps around to the opposite limit when the upper or lower limit of the range is exceeded. See spinButtonSetWrap.

Creates a new SpinButton.

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.

Replaces the Adjustment associated with spinButton.

Set the precision to be displayed by spinButton. Up to 20 digit precision is allowed.

Sets the step and page increments for spin_button. This affects how quickly the value changes when the spin button’s arrows are activated.

Sets the flag that determines if non-numeric text can be typed into the spin button.

Sets the minimum and maximum allowable values for spinButton.

If the current value is outside this range, it will be adjusted to fit within the range, otherwise it will remain unchanged.

Sets the policy as to whether values are corrected to the nearest step increment when a spin button is activated after providing an invalid value.

Sets the update behavior of a spin button. This determines whether the spin button is always updated or only when a valid value is set.

Sets the value of spinButton.

Sets the flag that determines if a spin button value wraps around to the opposite limit when the upper or lower limit of the range is exceeded.

Increment or decrement a spin button’s value in a specified direction by a specified amount.

Manually force an update of the spin button.

Type for the callback on the (unwrapped) C side.

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.

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

Wrap the callback into a GClosure.

Generate a function pointer callable from C code, from a C_SpinButtonChangeValueCallback.

A convenience synonym for Nothing :: Maybe SpinButtonChangeValueCallback.

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

Wrap a SpinButtonChangeValueCallback into a C_SpinButtonChangeValueCallback.

Type for the callback on the (unwrapped) C side.

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.

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

Wrap the callback into a GClosure.

Generate a function pointer callable from C code, from a C_SpinButtonInputCallback.

Type for the callback on the (unwrapped) C side.

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;
}

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

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

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

Wrap the callback into a GClosure.
