Expand description

Trait containing all GLWindow methods.

§Implementors

GLWindow

Provided Methods§

source

fn controls_viewport(&self) -> bool

Checks if self controls the GL viewport.

§Returns

true if self controls the GL viewport, otherwise false

source

fn draw(&self)

Redraw the window contents. Implementations should invoke the draw callback.

source

fn context(&self) -> GLContext

§Returns

the GLContext associated with this self

source

fn surface_dimensions(&self) -> (u32, u32)

§Returns
§width

resulting surface width

§height

resulting surface height

source

fn handle_events(&self, handle_events: bool)

Tell a self that it should handle events from the window system. These events are forwarded upstream as navigation events. In some window systems events are not propagated in the window hierarchy if a client is listening for them. This method allows you to disable events handling completely from the self.

§handle_events

a gboolean indicating if events should be handled or not.

source

fn has_output_surface(&self) -> bool

Query whether self has output surface or not

§Returns

true if self has useable output surface

source

fn queue_resize(&self)

Queue resizing of self.

source

fn quit(&self)

Quit the runloop’s execution.

source

fn resize(&self, width: u32, height: u32)

Resize self to the given width and height.

§width

new width

§height

new height

source

fn run(&self)

Start the execution of the runloop.

source

fn send_key_event(&self, event_type: &str, key_str: &str)

source

fn send_mouse_event(&self, event_type: &str, button: i32, posx: f64, posy: f64)

source

fn send_scroll_event(&self, posx: f64, posy: f64, delta_x: f64, delta_y: f64)

Notify a self about a scroll event. A scroll signal holding the event coordinates will be emitted.

§posx

x position of the mouse cursor

§posy

y position of the mouse cursor

§delta_x

the x offset of the scroll event

§delta_y

the y offset of the scroll event

source

fn set_preferred_size(&self, width: i32, height: i32)

Set the preferred width and height of the window. Implementations are free to ignore this information.

§width

new preferred width

§height

new preferred height

source

fn set_render_rectangle( &self, x: i32, y: i32, width: i32, height: i32, ) -> Result<(), BoolError>

Tell a self that it should render into a specific region of the window according to the gst_video::VideoOverlay interface.

§x

x position

§y

y position

§width

width

§height

height

§Returns

whether the specified region could be set

source

fn show(&self)

Present the window to the screen.

source

fn connect_key_event<F: Fn(&Self, &str, &str) + Send + Sync + 'static>( &self, f: F, ) -> SignalHandlerId

Will be emitted when a key event is received by the GstGLwindow.

§id

the name of the event

§key

the id of the key pressed

source

fn connect_mouse_event<F: Fn(&Self, &str, i32, f64, f64) + Send + Sync + 'static>( &self, f: F, ) -> SignalHandlerId

Will be emitted when a mouse event is received by the GstGLwindow.

§id

the name of the event

§button

the id of the button

§x

the x coordinate of the mouse event

§y

the y coordinate of the mouse event

source

fn connect_scroll_event<F: Fn(&Self, f64, f64, f64, f64) + Send + Sync + 'static>( &self, f: F, ) -> SignalHandlerId

Will be emitted when a mouse scroll event is received by the GstGLwindow.

§x

the x coordinate of the mouse event

§y

the y coordinate of the mouse event

§delta_x

the x offset of the scroll event

§delta_y

the y offset of the scroll event

source

fn connect_window_handle_changed<F: Fn(&Self) + Send + Sync + 'static>( &self, f: F, ) -> SignalHandlerId

Will be emitted when the window handle has been set into the native implementation, but before the context is re-activated. By using this signal, elements can refresh associated resource without relying on direct handle comparision.

Object Safety§

This trait is not object safe.
