getGLTextureBuilderFormat :: (MonadIO m, IsGLTextureBuilder o) => o -> m MemoryFormatgi-gdk4 GI.Gdk.Objects.GLTextureBuilder Get the value of the “format” property. When overloading is enabled, this is equivalent to
get gLTextureBuilder #format
setGLTextureBuilderFormat :: (MonadIO m, IsGLTextureBuilder o) => o -> MemoryFormat -> m ()gi-gdk4 GI.Gdk.Objects.GLTextureBuilder Set the value of the “format” property. When overloading is enabled, this is equivalent to
set gLTextureBuilder [ #format := value ]
textureGetFormat :: (HasCallStack, MonadIO m, IsTexture a) => a -> m MemoryFormatgi-gdk4 GI.Gdk.Objects.Texture Gets the memory format most closely associated with the data of the texture. Note that it may not be an exact match for texture data stored on the GPU or with compression. The format can give an indication about the bit depth and opacity of the texture and is useful to determine the best format for downloading the texture. Since: 4.10
textureNewForPixbuf :: (HasCallStack, MonadIO m, IsPixbuf a) => a -> m Texturegi-gdk4 GI.Gdk.Objects.Texture Creates a new texture object representing the GdkPixbuf. This function is threadsafe, so that you can e.g. use GTask and taskRunInThread to avoid blocking the main thread while loading a big image.
module GI.Gdk.Structs.
ContentFormats The GdkContentFormats structure is used to advertise and negotiate the format of content. You will encounter GdkContentFormats when interacting with objects controlling operations that pass data between different widgets, window or application, like Drag, Drop, Clipboard or ContentProvider. GDK supports content in 2 forms: GType and mime type. Using GTypes is meant only for in-process content transfers. Mime types are meant to be used for data passing both in-process and out-of-process. The details of how data is passed is described in the documentation of the actual implementations. To transform between the two forms, ContentSerializer and ContentDeserializer are used. A GdkContentFormats describes a set of possible formats content can be exchanged in. It is assumed that this set is ordered. GTypes are more important than mime types. Order between different GTypes or mime types is the order they were added in, most important first. Functions that care about order, such as contentFormatsUnion, will describe in their documentation how they interpret that order, though in general the order of the first argument is considered the primary order of the result, followed by the order of further arguments. For debugging purposes, the function contentFormatsToString exists. It will print a comma-separated list of formats from most important to least important. GdkContentFormats is an immutable struct. After creation, you cannot change the types it represents. Instead, new GdkContentFormats have to be created. The ContentFormatsBuilder structure is meant to help in this endeavor.

contentFormatsContainGtype :: (HasCallStack, MonadIO m) => ContentFormats -> GType -> m Boolgi-gdk4 GI.Gdk.Structs.ContentFormats Checks if a given GType is part of the given formats.
contentFormatsContainMimeType :: (HasCallStack, MonadIO m) => ContentFormats -> Text -> m Boolgi-gdk4 GI.Gdk.Structs.ContentFormats Checks if a given mime type is part of the given formats.
contentFormatsGetGtypes :: (HasCallStack, MonadIO m) => ContentFormats -> m (Maybe [GType], CSize)gi-gdk4 GI.Gdk.Structs.ContentFormats Gets the GTypes included in formats. Note that formats may not contain any GTypes, in particular when they are empty. In that case Nothing will be returned.
