Types

type ZwpLinuxBufferParamsV1 

type ZwpLinuxBufferParamsV1 struct {
	wl.BaseProxy
	// contains filtered or unexported fields
}

func NewZwpLinuxBufferParamsV1 

func NewZwpLinuxBufferParamsV1(ctx *wl.Context, id int) *ZwpLinuxBufferParamsV1

func (*ZwpLinuxBufferParamsV1) AddAddHandler 

func (p *ZwpLinuxBufferParamsV1) AddAddHandler(h ZwpLinuxBufferParamsV1AddHandler)

func (*ZwpLinuxBufferParamsV1) AddCreateHandler 

func (p *ZwpLinuxBufferParamsV1) AddCreateHandler(h ZwpLinuxBufferParamsV1CreateHandler)

func (*ZwpLinuxBufferParamsV1) AddCreateImmedHandler 

func (p *ZwpLinuxBufferParamsV1) AddCreateImmedHandler(h ZwpLinuxBufferParamsV1CreateImmedHandler)

func (*ZwpLinuxBufferParamsV1) AddDestroyHandler 

func (p *ZwpLinuxBufferParamsV1) AddDestroyHandler(h ZwpLinuxBufferParamsV1DestroyHandler)

func (*ZwpLinuxBufferParamsV1) Created 

func (p *ZwpLinuxBufferParamsV1) Created(id int) (*wl.Buffer, error)

Created will buffer creation succeeded.

This event indicates that the attempted buffer creation was successful. It provides the new wl_buffer referencing the dmabuf(s).

Upon receiving this event, the client should destroy the zlinux_dmabuf_params object.

func (*ZwpLinuxBufferParamsV1) Dispatch 

func (p *ZwpLinuxBufferParamsV1) Dispatch(event *wl.Event)

func (*ZwpLinuxBufferParamsV1) Failed 

func (p *ZwpLinuxBufferParamsV1) Failed() error

Failed will buffer creation failed.

This event indicates that the attempted buffer creation has failed. It usually means that one of the dmabuf constraints has not been fulfilled.

Upon receiving this event, the client should destroy the zlinux_buffer_params object.

func (*ZwpLinuxBufferParamsV1) RemoveAddHandler 

func (p *ZwpLinuxBufferParamsV1) RemoveAddHandler(h ZwpLinuxBufferParamsV1AddHandler)

func (*ZwpLinuxBufferParamsV1) RemoveCreateHandler 

func (p *ZwpLinuxBufferParamsV1) RemoveCreateHandler(h ZwpLinuxBufferParamsV1CreateHandler)

func (*ZwpLinuxBufferParamsV1) RemoveCreateImmedHandler 

func (p *ZwpLinuxBufferParamsV1) RemoveCreateImmedHandler(h ZwpLinuxBufferParamsV1CreateImmedHandler)

func (*ZwpLinuxBufferParamsV1) RemoveDestroyHandler 

func (p *ZwpLinuxBufferParamsV1) RemoveDestroyHandler(h ZwpLinuxBufferParamsV1DestroyHandler)

	// contains filtered or unexported fields
}

func NewZwpLinuxDmabufV1 

func NewZwpLinuxDmabufV1(ctx *wl.Context, id int) *ZwpLinuxDmabufV1

func (*ZwpLinuxDmabufV1) AddCreateParamsHandler 

func (p *ZwpLinuxDmabufV1) AddCreateParamsHandler(h ZwpLinuxDmabufV1CreateParamsHandler)

func (*ZwpLinuxDmabufV1) AddDestroyHandler 

func (p *ZwpLinuxDmabufV1) AddDestroyHandler(h ZwpLinuxDmabufV1DestroyHandler)

func (*ZwpLinuxDmabufV1) Dispatch 

func (p *ZwpLinuxDmabufV1) Dispatch(event *wl.Event)

func (*ZwpLinuxDmabufV1) Format 

func (p *ZwpLinuxDmabufV1) Format(format uint32) error

Format will supported buffer format.

This event advertises one buffer format that the server supports. All the supported formats are advertised once when the client binds to this interface. A roundtrip after binding guarantees that the client has received all supported formats.

For the definition of the format codes, see the zwp_linux_buffer_params_v1::create request.

Warning: the 'format' event is likely to be deprecated and replaced with the 'modifier' event introduced in zwp_linux_dmabuf_v1 version 3, described below. Please refrain from using the information received from this event.

func (*ZwpLinuxDmabufV1) Modifier 

func (p *ZwpLinuxDmabufV1) Modifier(format uint32, modifier_hi uint32, modifier_lo uint32) error

Modifier will supported buffer format modifier.

This event advertises the formats that the server supports, along with the modifiers supported for each format. All the supported modifiers for all the supported formats are advertised once when the client binds to this interface. A roundtrip after binding guarantees that the client has received all supported format-modifier pairs.

For legacy support, DRM_FORMAT_MOD_INVALID (that is, modifier_hi == 0x00ffffff and modifier_lo == 0xffffffff) is allowed in this event. It indicates that the server can support the format with an implicit modifier. When a plane has DRM_FORMAT_MOD_INVALID as its modifier, it is as if no explicit modifier is specified. The effective modifier will be derived from the dmabuf.

For the definition of the format and modifier codes, see the zwp_linux_buffer_params_v1::create and zwp_linux_buffer_params_v1::add requests.
