Struct sciter::host::Host

pub struct Host { /* fields omitted */ }

Sciter host runtime support.

Methods

impl Host

fn attach(hwnd: HWINDOW) -> Host

Attach Sciter host to existing window.

Usually Sciter window created by sciter::Window::create(), but you can attach Sciter to the existing native window. In this case you need to mix-in window events processing with SciterProcND. Sciter engine will be initialized either on WM_CREATE or WM_INITDIALOG response or by calling SciterCreateOnDirectXWindow.

fn setup_callback<T: HostHandler>(&self, hwnd: HWINDOW, handler: T)

Set callback for Sciter engine events.

fn attach_handler<T: EventHandler>(&self, handler: T)

Attach dom::EventHandler to the Sciter window.

fn enable_debug(&self, enable: bool)

Set debug mode for specific window or globally.

fn get_hwnd(&self) -> HWINDOW

Get native window handle.

fn get_root(&self) -> Option<Element>

Get window root DOM element.

fn load_file(&self, uri: &str)

Load HTML document from file.

fn load_html(&self, html: &[u8], uri: Option<&str>)

Load HTML document from memory.

fn data_ready(&self, uri: &str, data: &[u8])

This function is used as response to SC_LOAD_DATA request.

fn data_ready_async(&self,
                    uri: &str,
                    data: &[u8],
                    request_id: Option<*mut _HREQUEST>)

Use this function outside of SCN_LOAD_DATA request.

It can be used for the two purposes:

1. Asynchronious resource loading in respect of SCN_LOAD_DATA requests (you must provide request_id in this case).
2. Refresh of already loaded resource (for example, dynamic image updates).

fn eval_script(&self, script: &str) -> Result<Value, Value>

Evaluate script in context of current document.

fn call_function(&self, name: &str, args: &[Value]) -> Result<Value, Value>

Call scripting function defined in the global namespace.

This function returns Result<Value,Value> with script function result value or with sciter script error. You can use the make_args!(a,b,c) macro which help you construct script arguments from Rust types.

fn set_option(&self, option: SCITER_RT_OPTIONS, value: usize) -> Result<()>

Set various sciter engine options, see the SCITER_RT_OPTIONS.

fn set_home_url(&self, url: &str) -> Result<()>

Set home url for sciter resources.

If you will set it like set_home_url("http://sciter.com/modules/") then

<script src="sciter:lib/root-extender.tis"> will load root-extender.tis from

http://sciter.com/modules/lib/root-extender.tis.

fn set_media_type(&self, media_type: &str) -> Result<()>

Set media type of this sciter instance.

fn set_media_vars(&self, media: Value) -> Result<()>

Set media variables (dictionary) for this sciter instance.

By default sciter window has "screen:true" and "desktop:true"/"handheld:true" media variables.

Media variables can be changed in runtime. This will cause styles of the document to be reset.

fn set_master_css(&self, css: &str, append: bool) -> Result<()>

Set or append the master style sheet styles (globally).

fn set_window_css(&self,
                  css: &str,
                  base_url: &str,
                  media_type: &str)
                  -> Result<()>

Set (reset) style sheet of current document.
