Constructor Details

Builder

protected Builder()

Default constructor for a Builder object.

Method Details

build

public Button build()

Finish building the Button 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 Button.

Overrides:

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

Returns:

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

setCanShrink

public B setCanShrink(boolean canShrink)

Whether the size of the button can be made smaller than the natural size of its contents.

For text buttons, setting this property will allow ellipsizing the label.

If the contents of a button are an icon or a custom widget, setting this property has no effect.

Parameters:

canShrink - the value for the can-shrink property

Returns:

the Builder instance is returned, to allow method chaining

Since:

4.12

setChild

public B setChild(Widget child)

The child widget.

Parameters:

child - the value for the child property

Returns:

the Builder instance is returned, to allow method chaining

setHasFrame

public B setHasFrame(boolean hasFrame)

Whether the button has a frame.

Parameters:

hasFrame - the value for the has-frame property

Returns:

the Builder instance is returned, to allow method chaining

setIconName

public B setIconName(String iconName)

The name of the icon used to automatically populate the button.

Parameters:

iconName - the value for the icon-name property

Returns:

the Builder instance is returned, to allow method chaining

setLabel

public B setLabel(String label)

Text of the label inside the button, if the button contains a label widget.

Parameters:

label - the value for the label property

Returns:

the Builder instance is returned, to allow method chaining

setUseUnderline

public B setUseUnderline(boolean useUnderline)

If set, an underline in the text indicates that the following character is to be used as mnemonic.

Parameters:

useUnderline - the value for the use-underline property

Returns:

the Builder instance is returned, to allow method chaining

onActivate

public B onActivate(Button.ActivateCallback handler)

Emitted to animate press then release.

This is an action signal. Applications should never connect to this signal, but use the Gtk.Button::clicked signal.

The default bindings for this signal are all forms of the ␣ and Enter keys.

Parameters:

handler - the signal handler

Returns:

the Builder instance is returned, to allow method chaining

See Also:

• Button.ActivateCallback.run()

onClicked

public B onClicked(Button.ClickedCallback handler)

Emitted when the button has been activated (pressed and released).

Parameters:

handler - the signal handler

Returns:

the Builder instance is returned, to allow method chaining
