class: DmabufFormats

[21:7] extends: object

Provides information about supported DMA buffer formats. You can query whether a given format is supported with [method@Gdk.DmabufFormats.contains] and you can iterate over the list of all supported formats with [method@Gdk.DmabufFormats.get_n_formats] and [method@Gdk.DmabufFormats.get_format]. The list of supported formats is sorted by preference, with the best formats coming first. The list may contains (format, modifier) pairs where the modifier is DMA_FORMAT_MOD_INVALID, indicating that implicit modifiers may be used with this format. See [class@Gdk.DmabufTextureBuilder] for more information about DMA buffers. Note that DMA buffers only exist on Linux.

Methods

• DmabufFormats (Handle = null)

  Creates a new DmabufFormats by wrapping a native handle or another wrapper.

  • @p Handle is the native handle or another wrapper whose handle to adopt.

• toNativeHandle (Source)

  Normalizes a constructor argument into a raw pointer carrier. Accepts a raw NativeHandle, a raw NativeBuffer returned from fn.call(...), another generated wrapper exposing handle(), or null. Returns null when the argument carries no pointer.

  • @p Source is the raw handle, raw buffer, wrapper, or null.
  • @r A raw pointer carrier or null when no pointer is present.

• getLib ()

  Returns the opened native library for this generated wrapper.

  • @r The opened native library.

• handle ()

  Returns the wrapped NativeHandle.

  • @r The wrapped NativeHandle.

• isNull ()

  Returns true when the wrapped handle is null.

  • @r A bool.

• describe ()

  Returns a small string for debugging generated wrappers.
