Trait Implementations

impl Clone for MsgDialogState

fn clone(&self) -> MsgDialogState

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MsgDialogState

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for MsgDialogState

fn default() -> Self

Returns the “default value” for a type.

impl HandleEvent<Event, Dialog, Outcome> for MsgDialogState

fn handle(&mut self, event: &Event, _: Dialog) -> Outcome

Handle an event.

impl HasFocus for MsgDialogState

fn build(&self, _builder: &mut FocusBuilder)

Build the focus-structure for the container/widget.

fn focus(&self) -> FocusFlag

Access to the focus flag.

fn area(&self) -> Rect

Area for mouse focus.

fn build_nav(&self, navigable: Navigation, builder: &mut FocusBuilder)

Build the focus-structure for the container/widget.

fn id(&self) -> usize

Provide a unique id for the widget.

fn area_z(&self) -> u16

Z-value for the area.

fn navigable(&self) -> Navigation

Declares how the widget interacts with focus.

fn is_focused(&self) -> bool

Does this widget have the focus. Or, if the flag is used for a container, does any of widget inside the container have the focus.

fn lost_focus(&self) -> bool

This widget just lost the focus. This flag is set by [Focus::handle] if there is a focus transfer, and will be reset by the next call to [Focus::handle].

fn gained_focus(&self) -> bool

This widget just gained the focus. This flag is set by [Focus::handle] if there is a focus transfer, and will be reset by the next call to [Focus::handle].

fn has_mouse_focus(&self) -> bool

This flag is set by [Focus::handle], if a mouse-event matches one of the areas associated with a widget.

impl HasScreenCursor for MsgDialogState

fn screen_cursor(&self) -> Option<(u16, u16)>

This returns the cursor position if

impl RelocatableState for MsgDialogState

fn relocate(&mut self, shift: (i16, i16), clip: Rect)

Relocate the areas in this widgets state.

fn relocate_popup(&mut self, shift: (i16, i16), clip: Rect)

Relocate only popup areas. As rendering the popups is a separate render, this has to be separate too.

fn relocate_popup_hidden(&mut self)

Relocate all popup areas to a clip-rect (0,0+0x0).

fn relocate_hidden(&mut self)

Relocate all areas to a clip-rect (0,0+0x0).
