Implementations

impl NcSelector

pub fn new<'a>( plane: &mut NcPlane, options: &NcSelectorOptions, ) -> NcResult<&'a mut Self>

Creates a selector over a plane.

The selector will take care of destroying the plane.

pub fn builder() -> NcSelectorBuilder

Starts the builder.

pub fn offer_input(&mut self, input: impl Into<NcInput>) -> bool

Offers an input to the selector.

If it’s relevant, this function returns true, and the input ought not be processed further. If it’s irrelevant to the selector, false is returned.

Relevant inputs include:

• a mouse click on an item.
• a mouse scrollwheel event.
• a mouse click on the scrolling arrows.
• up, down, pgup, or pgdown on an unrolled menu (navigates among items).

pub fn destroy(&mut self) -> NcResult<()>

Destroys the NcSelector.

Note that this also destroys the NcPlane.

pub fn additem(&mut self, item: NcSelectorItem) -> NcResult<i32>

Adds an item.

pub fn delitem(&mut self, item: &str) -> NcResult<i32>

Deletes an item.

C style function: ncselector_delitem().

pub fn selected(&mut self) -> Option<String>

Returns the selected option if there is one.

C style function: ncselector_delitem().

pub fn nextitem(&mut self) -> NcResult<String>

Move down in the list. A reference to the newly-selected item is returned, or NULL if there are no items in the list.

pub fn previtem(&mut self) -> NcResult<String>

Move up in the list. A reference to the newly-selected item is returned, or NULL if there are no items in the list.
