[−][src]Struct pushrod_render::render::engine::Engine
This is a storage container for the Pushrod event engine.
Implementations
impl Engine
[src]
This is the heart of the Pushrod event engine, and is what is used to drive the interaction between the user and your application. The suggested method of use for this code is as follows:
Create a new object
Use Engine::new()
to instantiate a new object.
Set up the base
Call engine.setup(width, height)
, by passing the width and height of the window that is
being created for the main application. This is required, as a base widget is added to the
render list. This BaseWidget
is considered the parent of the application screen.
Add Widgets to the Engine
Call add_widget(Box::new(widget), "name".to_string())
to add your Widget
to the managed
display list.
Call Run()
Calling run(sdl, window)
will manage the application screen after all widgets have been added
to the display list.
That's all there is to it. If you want to see more interactions on how the Engine
is used in
an application, check out the demo test code, and look at rust-pushrod-chassis
.
pub fn new() -> Self
[src]
Creates a new Engine
object.
pub fn setup(&mut self, window_width: u32, window_height: u32)
[src]
Sets up the top-level widget so that other widgets can be added to the screen.
pub fn add_widget(
&mut self,
widget: Box<dyn Widget>,
widget_name: String
) -> i32
[src]
&mut self,
widget: Box<dyn Widget>,
widget_name: String
) -> i32
Adds a widget to the display list. Widgets are rendered in the order in which they were created in the display list.
pub fn run(&mut self, sdl: Sdl, window: Window)
[src]
Main application run loop, controls interaction between the user and the application.
