Required methods

fn apply_style<P: Is<Style>>(&self, style: &P)[src]

widget_apply_style: @widget: A #Widget @style: A #Style

Used to implement how a new style instance should be applied in the widget. For instance, setting style instance on stylable internal children.

fn get_available_area(&self, allocation: &ActorBox, area: &mut ActorBox)[src]

get_available_area: @widget: A #Widget @allocation: A #ActorBox @area: A #ActorBox

Copies @allocation into @area and accounts for the padding values. This gives the area that is available in which to allocate children with respect to padding.

fn get_background_color(&self) -> Option<Color>[src]

get_background_color: @actor: A #Widget

Get the color used as the background. This is set using the “background-color” CSS property. This function should normally only be used by subclasses.

Returns: (transfer none): a #Color

fn get_background_texture(&self) -> Option<Handle>[src]

fn get_disabled(&self) -> bool[src]

get_disabled: @widget: an #Widget

Get the value of the “disabled” property.

fn get_padding(&self) -> Padding[src]

get_padding: @widget: A #Widget @padding: (out): A pointer to an #Padding to fill

Gets the padding of the widget, set using the “padding” CSS property. This function should normally only be used by subclasses.

fn long_press_cancel(&self)[src]

long_press_cancel: @widget: An Widget

Cancel a long-press timeout if one is running and emit the signal to notify that the long-press has been cancelled.

fn long_press_query(&self, event: &mut Event)[src]

long_press_query: @widget: An Widget @event: the event used to determine whether to run a long-press

Emit the long-press query signal and start a long-press timeout if required.

fn set_disabled(&self, disabled: bool)[src]

widget_set_disabled: @widget: an #Widget @disabled: value to set

Set the disabled property. Disabled widgets have a “disabled” pseudo-class until disabled is set to #false.

fn connect_property_disabled_notify<F: Fn(&Self) + 'static>(
    &self,
    f: F
) -> SignalHandlerId[src]

fn connect_property_menu_notify<F: Fn(&Self) + 'static>(
    &self,
    f: F
) -> SignalHandlerId[src]

fn connect_property_tooltip_delay_notify<F: Fn(&Self) + 'static>(
    &self,
    f: F
) -> SignalHandlerId[src]

fn connect_property_tooltip_text_notify<F: Fn(&Self) + 'static>(
    &self,
    f: F
) -> SignalHandlerId[src]
