Trait containing all Button methods.

Implementors

Button, ColorButton, FontButton, LinkButton, LockButton, ModelButton, ScaleButton, ToggleButton

Required methods

fn clicked(&self)

Emits a Button::clicked signal to the given Button.

fn get_always_show_image(&self) -> bool

Returns whether the button will ignore the Settings:gtk-button-images setting and always show the image, if available.

Returns

true if the button will always show the image

fn get_event_window(&self) -> Option<Window>

Returns the button’s event window if it is realized, None otherwise. This function should be rarely needed.

Returns

self’s event window.

fn get_focus_on_click(&self) -> bool

Returns whether the button grabs focus when it is clicked with the mouse. See ButtonExt::set_focus_on_click.

Deprecated since 3.20

Use WidgetExt::get_focus_on_click instead

Returns

true if the button grabs focus when it is clicked with the mouse.

fn get_image(&self) -> Option<Widget>

Gets the widget that is currenty set as the image of self. This may have been explicitly set by ButtonExt::set_image or constructed by Button::new_from_stock.

Returns

a Widget or None in case there is no image

fn get_image_position(&self) -> PositionType

Gets the position of the image relative to the text inside the button.

Returns

the position

fn get_label(&self) -> Option<GString>

Fetches the text from the label of the button, as set by ButtonExt::set_label. If the label text has not been set the return value will be None. This will be the case if you create an empty button with Button::new to use as a container.

Returns

The text of the label widget. This string is owned by the widget and must not be modified or freed.

fn get_relief(&self) -> ReliefStyle

Returns the current relief style of the given Button.

Returns

The current ReliefStyle

fn get_use_underline(&self) -> bool

Returns whether an embedded underline in the button label indicates a mnemonic. See gtk_button_set_use_underline ().

Returns

true if an embedded underline in the button label indicates the mnemonic accelerator keys.

fn set_always_show_image(&self, always_show: bool)

If true, the button will ignore the Settings:gtk-button-images setting and always show the image, if available.

Use this property if the button would be useless or hard to use without the image.

always_show

true if the menuitem should always show the image

fn set_focus_on_click(&self, focus_on_click: bool)

Sets whether the button will grab focus when it is clicked with the mouse. Making mouse clicks not grab focus is useful in places like toolbars where you don’t want the keyboard focus removed from the main area of the application.

Deprecated since 3.20

Use WidgetExt::set_focus_on_click instead

focus_on_click

whether the button grabs focus when clicked with the mouse

fn set_image<'a, P: IsA<Widget> + 'a, Q: Into<Option<&'a P>>>(&self, image: Q)

Set the image of self to the given widget. The image will be displayed if the label text is None or if Button:always-show-image is true. You don’t have to call WidgetExt::show on image yourself.

image

a widget to set as the image for the button, or None to unset

fn set_image_position(&self, position: PositionType)

Sets the position of the image relative to the text inside the button.

position

the position

fn set_label(&self, label: &str)

Sets the text of the label of the button to str. This text is also used to select the stock item if Button::set_use_stock is used.

This will also clear any previously set labels.

label

a string

fn set_relief(&self, relief: ReliefStyle)

Sets the relief style of the edges of the given Button widget. Two styles exist, ReliefStyle::Normal and ReliefStyle::None. The default style is, as one can guess, ReliefStyle::Normal. The deprecated value ReliefStyle::Half behaves the same as ReliefStyle::Normal.

relief

The ReliefStyle as described above

fn set_use_underline(&self, use_underline: bool)

If true, an underline in the text of the button label indicates the next character should be used for the mnemonic accelerator key.

use_underline

true if underlines in the text indicate mnemonics

fn connect_activate<F: Fn(&Self) + 'static>(&self, f: F) -> SignalHandlerId

The ::activate signal on Button is an action signal and emitting it causes the button to animate press then release. Applications should never connect to this signal, but use the Button::clicked signal.

fn emit_activate(&self)

fn connect_clicked<F: Fn(&Self) + 'static>(&self, f: F) -> SignalHandlerId

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

fn emit_clicked(&self)

fn connect_property_always_show_image_notify<F: Fn(&Self) + 'static>(
    &self,
    f: F
) -> SignalHandlerId

fn connect_property_image_notify<F: Fn(&Self) + 'static>(
    &self,
    f: F
) -> SignalHandlerId

fn connect_property_image_position_notify<F: Fn(&Self) + 'static>(
    &self,
    f: F
) -> SignalHandlerId

fn connect_property_label_notify<F: Fn(&Self) + 'static>(
    &self,
    f: F
) -> SignalHandlerId

fn connect_property_relief_notify<F: Fn(&Self) + 'static>(
    &self,
    f: F
) -> SignalHandlerId

fn connect_property_use_underline_notify<F: Fn(&Self) + 'static>(
    &self,
    f: F
) -> SignalHandlerId
