Struct rustwlc::handle::WlcOutput

#[repr(C)]
pub struct WlcOutput(pub uintptr_t);

Represents a handle to a wlc output.

Methods

impl WlcOutput

fn as_view(self) -> WlcView

Compatability/debugging function.

wlc internally stores views and outputs under the same type. If for some reason a conversion between the two was required, this function could be called. If this is the case please submit a bug report.

fn is_null(self) -> bool

Determines if this is a null a output (invalid).

unsafe fn dummy(code: u32) -> WlcOutput

Create a dummy WlcOutput for testing purposes.

Unsafety

The following operations on a dummy WlcOutput will cause crashes:

• WlcOutput::focused when wlc is not running
• WlcOutput::list when wlc is not running
• WlcOutput::set_resolution on a dummy output

In addition, WlcOutput::set_views will return an error.

All other methods can be used on dummy outputs.

Example

unsafe {
    let output = WlcOutput::dummy(0u32);
    let output2 = WlcOutput::dummy(1u32);
    assert!(output < output2);
    assert!(output != output2);
}

unsafe fn get_user_data<T>(&self) -> Option<&mut T>

Gets user-specified data.

Unsafety

The wlc implementation of this method uses void* pointers for raw C data. This function will internaly do a conversion between the input T and a libc::c_void.

This is a highly unsafe conversion with no guarantees. As such, usage of these functions requires an understanding of what data they will have. Please review wlc's usage of these functions before attempting to use them yourself.

unsafe fn set_user_data<T>(&self, data: &T)

Sets user-specified data.

Unsafety

The wlc implementation of this method uses void* pointers for raw C data. This function will internaly do a conversion between the input T and a libc::c_void.

This is a highly unsafe conversion with no guarantees. As such, usage of these functions requires an understanding of what data they will have. Please review wlc's usage of these functions before attempting to use them yourself.

fn schedule_render(self)

Schedules output for rendering next frame.

If the output was already scheduled, this is a no-op; if output is currently rendering, it will render immediately after.

fn list() -> Vec<WlcOutput>

Gets a list of the current outputs.

Safety

This function will crash the program if run when wlc is not running.

fn focused() -> WlcOutput

Gets the currently focused output.

Safety

This function will crash the program if run when wlc is not running.

fn get_name(self) -> String

Gets the name of the WlcOutput.

Names are usually assigned in the format WLC-n, where the first output is WLC-1.

fn get_sleep(self) -> bool

Gets the sleep status of the output.

Returns true if the monitor is sleeping, such as having been set with set_sleep.

fn set_sleep(self, sleep: bool)

Sets the sleep status of the output.

fn get_resolution(self) -> Option<Size>

Gets the output's real resolution. Do not use for coordinate boundary.

fn get_virtual_resolution(self) -> Option<Size>

Get the virtual resolution. Helpful for getting resolution on high dpi displays. Use this to calculate coordinate boundary.

fn set_resolution(self, size: Size, scaling: u32)

Sets the resolution of the output.

Safety

This method will crash the program if use when wlc is not running.

fn get_scale(self) -> u32

Get the scaling for the output.

fn get_views(self) -> Vec<WlcView>

Get views in stack order.

This is mainly useful for wm's who need another view stack for inplace sorting. For example tiling wms, may want to use this to keep their tiling order separated from floating order. This handles wlc_output_get_views and wlc_output_get_mutable_views.

fn get_mask(self) -> u32

Gets the mask of this output

fn set_mask(self, mask: u32)

Sets the mask for this output

fn get_mutable_views(self) -> Vec<WlcView>

Deprecated since 0.5.3

: please use get_views

Deprecated

This function is equivalent to simply calling get_views

fn set_views(self, views: &[WlcView]) -> Result<(), &'static str>

Attempts to set the views of a given output.

Returns success if operation succeeded. An error will be returned if something went wrong or if wlc isn't running.

fn focus(output: Option<WlcOutput>)

Focuses compositor on a specific output.

Pass in Option::None for no focus.

fn get_render(&self) -> wlc_renderer

Gets the renderer in use for this WlcOutput
