pub struct App {}

Available on crate feature dep_fltk only.

Basic Application struct, used to instantiate, set the scheme and run the event loop

Implementations

impl App

pub fn set_scheme(&mut self, scheme: Scheme)

Sets the scheme of the application

pub fn with_scheme(self, scheme: Scheme) -> App

Sets the scheme of the application

pub fn scheme(self) -> Scheme

Gets the scheme of the application

pub fn run(self) -> Result<(), FltkError>

Runs the event loop

Errors

pub fn wait(self) -> bool

Wait for incoming messages. Calls to redraw within wait require an explicit sleep

pub fn load_system_fonts(self) -> App

Loads system fonts

pub fn load_font<P>(self, path: P) -> Result<String, FltkError>

where P: AsRef<Path>,

Loads a font from a path. On success, returns a String with the ttf Font Family name. The font’s index is always 16. As such only one font can be loaded at a time. The font name can be used with Font::by_name, and index with Font::by_index.

Examples

use fltk::{prelude::*, *};
let app = app::App::default();
let font = app.load_font("font.ttf").unwrap();
let mut frame = frame::Frame::new(0, 0, 400, 100, "Hello");
frame.set_label_font(enums::Font::by_name(&font));

Errors

Returns ResourceNotFound if the Font file was not found

pub fn set_visual(self, mode: Mode) -> Result<(), FltkError>
