Constructor Details

Builder

protected Builder()

Default constructor for a Builder object.

Method Details

build

public SpinButton build()

Finish building the SpinButton object. This will call GObject.withProperties(org.gnome.glib.Type, java.lang.String[], org.gnome.gobject.Value[]) to create a new GObject instance, which is then cast to SpinButton.

Overrides:

build in class Widget.Builder<B extends SpinButton.Builder<B>>

Returns:

a new instance of SpinButton with the properties that were set in the Builder object.

setActivatesDefault

public B setActivatesDefault(boolean activatesDefault)

Whether to activate the default widget when the spin button is activated.

See Gtk.SpinButton::activate for what counts as activation.

Parameters:

activatesDefault - the value for the activates-default property

Returns:

the Builder instance is returned, to allow method chaining

Since:

4.14

setAdjustment

public B setAdjustment(Adjustment adjustment)

The adjustment that holds the value of the spin button.

Parameters:

adjustment - the value for the adjustment property

Returns:

the Builder instance is returned, to allow method chaining

setClimbRate

public B setClimbRate(double climbRate)

The acceleration rate when you hold down a button or key.

Parameters:

climbRate - the value for the climb-rate property

Returns:

the Builder instance is returned, to allow method chaining

setDigits

public B setDigits(int digits)

The number of decimal places to display.

Parameters:

digits - the value for the digits property

Returns:

the Builder instance is returned, to allow method chaining

setNumeric

public B setNumeric(boolean numeric)

Whether non-numeric characters should be ignored.

Parameters:

numeric - the value for the numeric property

Returns:

the Builder instance is returned, to allow method chaining

setSnapToTicks

public B setSnapToTicks(boolean snapToTicks)

Whether erroneous values are automatically changed to the spin buttons nearest step increment.

Parameters:

snapToTicks - the value for the snap-to-ticks property

Returns:

the Builder instance is returned, to allow method chaining

setUpdatePolicy

public B setUpdatePolicy(SpinButtonUpdatePolicy updatePolicy)

Whether the spin button should update always, or only when the value is acceptable.

Parameters:

updatePolicy - the value for the update-policy property

Returns:

the Builder instance is returned, to allow method chaining

setValue

public B setValue(double value)

The current value.

Parameters:

value - the value for the value property

Returns:

the Builder instance is returned, to allow method chaining

setWrap

public B setWrap(boolean wrap)

Whether a spin button should wrap upon reaching its limits.

Parameters:

wrap - the value for the wrap property

Returns:

the Builder instance is returned, to allow method chaining

onActivate

public B onActivate(SpinButton.ActivateCallback handler)

Emitted when the spin button is activated.

The keybindings for this signal are all forms of the Enter key.

If the Enter key results in the value being committed to the spin button, then activation does not occur until Enter is pressed again.

Parameters:

handler - the signal handler

Returns:

the Builder instance is returned, to allow method chaining

Since:

4.14

See Also:

• SpinButton.ActivateCallback.run()

onChangeValue

public B onChangeValue(SpinButton.ChangeValueCallback handler)

Emitted when the user initiates a value change.

This is a keybinding signal.

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/PageDown.

Parameters:

handler - the signal handler

Returns:

the Builder instance is returned, to allow method chaining

See Also:

• SpinButton.ChangeValueCallback.run(org.gnome.gtk.ScrollType)

onInput

public B onInput(SpinButton.InputCallback handler)

Emitted to convert the users input into a double value.

The signal handler is expected to use Editable.getText() to retrieve the text of the spinbutton and set newValue to the new value.

The default conversion uses g_strtod().

Parameters:

handler - the signal handler

Returns:

the Builder instance is returned, to allow method chaining

See Also:

• SpinButton.InputCallback.run(org.javagi.base.Out<java.lang.Double>)

onOutput

public B onOutput(SpinButton.OutputCallback handler)

Emitted to tweak the formatting of the value for display.

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

    value = gtk_spin_button_get_value_as_int (spin);
    text = g_strdup_printf ("%02d", value);
    gtk_editable_set_text (GTK_EDITABLE (spin), text):
    g_free (text);

    return TRUE;
 }
 

Parameters:

handler - the signal handler

Returns:

the Builder instance is returned, to allow method chaining

See Also:

• SpinButton.OutputCallback.run()

onValueChanged

public B onValueChanged(SpinButton.ValueChangedCallback handler)

Emitted when the value is changed.

Also see the Gtk.SpinButton::output signal.

Parameters:

handler - the signal handler

Returns:

the Builder instance is returned, to allow method chaining

See Also:

• SpinButton.ValueChangedCallback.run()

onWrapped

public B onWrapped(SpinButton.WrappedCallback handler)

Emitted right after the spinbutton wraps from its maximum to its minimum value or vice-versa.

Parameters:

handler - the signal handler

Returns:

the Builder instance is returned, to allow method chaining

See Also:

• SpinButton.WrappedCallback.run()
