Trait containing all GLWindow methods.

Implementors

GLWindow

Required methods

fn controls_viewport(&self) -> bool

Checks if self controls the GL viewport.

Feature: v1_16

Returns

true if self controls the GL viewport, otherwise false

fn draw(&self)

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

fn get_context(&self) -> Option<GLContext>

Returns

the GLContext associated with this self

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

width

resulting surface width

height

resulting surface height

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.

fn queue_resize(&self)

Queue resizing of self.

fn quit(&self)

Quit the runloop's execution.

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

Resize self to the given width and height.

width

new width

height

new height

fn run(&self)

Start the execution of the runloop.

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

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

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

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

fn show(&self)

Present the window to the screen.

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

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
