Struct SdlPlatform

pub struct SdlPlatform { /* private fields */ }

SDL2 backend platform state.

A backend platform handles window/input device events and manages their state.

There are three things you need to do to use this library correctly:

1. Initialize a SdlPlatform instance
2. Pass events to the platform (every frame)
3. Call frame preparation callback (every frame)

Implementations

impl SdlPlatform

pub fn new(imgui: &mut Context) -> SdlPlatform

Initializes a SDL platform instance and configures imgui.

This function configures imgui-rs in the following ways:

• backend flags are updated
• keys are configured
• platform name is set

pub fn init(imgui: &mut Context) -> SdlPlatform

👎Deprecated: use new instead

Initializes a SDL platform instance and configures imgui.

Deprecated since 0.13.0 – use new instead

pub fn handle_event(&mut self, context: &mut Context, event: &Event) -> bool

Handles a SDL event.

This function performs the following actions (depends on the event):

• keyboard state is updated
• mouse state is updated

pub fn prepare_frame( &mut self, context: &mut Context, window: &Window, event_pump: &EventPump, )

Frame preparation callback.

Call this before calling the imgui-rs context frame function. This function performs the following actions:

• display size and the framebuffer scale is set
• mouse cursor is repositioned (if requested by imgui-rs)
• current mouse cursor position is passed to imgui-rs
• changes mouse cursor icon (if requested by imgui-rs)
