type QLFileThumbnailRequest 

type QLFileThumbnailRequest struct {
	foundation.NSObject
}

A request to generate a thumbnail for a custom file type.

Apple documentation: https://developer.apple.com/documentation/quicklookthumbnailing/qlfilethumbnailrequest

func QLFileThumbnailRequestFromID 

func QLFileThumbnailRequestFromID(id objc.ID) *QLFileThumbnailRequest

func (*QLFileThumbnailRequest) FileURL 

func (o *QLFileThumbnailRequest) FileURL() *foundation.NSURL

The url of the file for which a thumbnail is being requested.

func (*QLFileThumbnailRequest) MaximumSize 

func (o *QLFileThumbnailRequest) MaximumSize() corefoundation.CGSize

The maximum size of the generated thumbnail that will be accepted. This is also the preferred size, ideally either the width or the height will match the maximumSize's width or height respectively.

func (*QLFileThumbnailRequest) MinimumSize 

func (o *QLFileThumbnailRequest) MinimumSize() corefoundation.CGSize

The minimum size of the generated thumbnail that will be accepted.

func (*QLFileThumbnailRequest) Scale 

func (o *QLFileThumbnailRequest) Scale() float64

The scale of the requested thumbnail.

type QLThumbnailError 

type QLThumbnailError int64

Error information that might return when you generate a thumbnail. 

const (
	QLThumbnailErrorGenerationFailed  QLThumbnailError = 0
	QLThumbnailErrorSavingToURLFailed QLThumbnailError = 1
	QLThumbnailErrorNoCachedThumbnail QLThumbnailError = 2
	QLThumbnailErrorNoCloudThumbnail  QLThumbnailError = 3

)

func (QLThumbnailError) String 

func (e QLThumbnailError) String() string

type QLThumbnailGenerationRequest 

type QLThumbnailGenerationRequest struct {
	foundation.NSObject
}

A request to generate a thumbnail for a file.

Apple documentation: https://developer.apple.com/documentation/quicklookthumbnailing/qlthumbnailgenerationrequest

func QLThumbnailGenerationRequestFromID 

func QLThumbnailGenerationRequestFromID(id objc.ID) *QLThumbnailGenerationRequest

func (*QLThumbnailGenerationRequest) ContentType 

func (o *QLThumbnailGenerationRequest) ContentType() *uniformtypeidentifiers.UTType

The content type of the file being thumbnailed is used to determine the provider of the thumbnail and the icon styles applied if iconMode is requested. By default the content type is derived from the file extension. Setting this property will override the derived content type. This is useful for files that don't have meaningful extensions but for which you may already know the content type.

func (*QLThumbnailGenerationRequest) IconMode 

func (o *QLThumbnailGenerationRequest) IconMode() bool

If set to YES, this will generate something appropriate for display as a file icon, meaning that the thumbnail might be embedded in a frame, show a curled corner, draw a background and/or a drop shadow, as appropriate for the platform. If set to NO, this will generate a raw undecorated thumbnail. Defaults to NO.

func (*QLThumbnailGenerationRequest) InitWithFileAtURLSizeScaleRepresentationTypes 

func (o *QLThumbnailGenerationRequest) InitWithFileAtURLSizeScaleRepresentationTypes(url *foundation.NSURL, size corefoundation.CGSize, scale float64, representationTypes QLThumbnailGenerationRequestRepresentationTypes) *QLThumbnailGenerationRequest

@param url The url of the file on disk for which a thumbnail is requested. @param size The desired size of the thumbnails that should be generated. @param scale The desired scale of the thumbnails that should be generated. This will usually be the scale of the screen. You can for instance pass a scale different from the one of the screen if you would like to save generated thumbnails to a server to later download them on devices with a different screen scale. @param representationTypes The desired successive representations of the thumbnail that should be generated when possible.

func (*QLThumbnailGenerationRequest) MinimumDimension 

func (o *QLThumbnailGenerationRequest) MinimumDimension() float64

Defaults to 0. If set, the thumbnail will have a width and height greater or equal to minimumDimension * scale. If set and it is not possible to generate thumbnails of minimumDimension for any of the requested QLThumbnailGenerationRequestRepresentationTypes, no thumbnail will be provided.

func (*QLThumbnailGenerationRequest) RepresentationTypes 

func (o *QLThumbnailGenerationRequest) RepresentationTypes() QLThumbnailGenerationRequestRepresentationTypes

func (*QLThumbnailGenerationRequest) Scale 

func (o *QLThumbnailGenerationRequest) Scale() float64

func (*QLThumbnailGenerationRequest) SetContentType

func QLThumbnailGeneratorFromID(id objc.ID) *QLThumbnailGenerator

func QLThumbnailGeneratorSharedGenerator 

func QLThumbnailGeneratorSharedGenerator() *QLThumbnailGenerator

func (*QLThumbnailGenerator) CancelRequest 

func (o *QLThumbnailGenerator) CancelRequest(request *QLThumbnailGenerationRequest)

Cancels the generation of a thumbnail for a given request.

func (*QLThumbnailGenerator) GenerateBestRepresentationForRequestCompletionHandler 

func (o *QLThumbnailGenerator) GenerateBestRepresentationForRequestCompletionHandler(request *QLThumbnailGenerationRequest, completionHandler func(*QLThumbnailRepresentation, unsafe.Pointer))

Generates the best possible thumbnail representation for a file and calls a handler upon completion.

func (*QLThumbnailGenerator) GenerateRepresentationsForRequestUpdateHandler 

func (o *QLThumbnailGenerator) GenerateRepresentationsForRequestUpdateHandler(request *QLThumbnailGenerationRequest, updateHandler func(*QLThumbnailRepresentation, QLThumbnailRepresentationType, unsafe.Pointer))

Generates various thumbnail representations for a file and calls the update handler for each thumbnail representation.

func (*QLThumbnailGenerator) SaveBestRepresentationForRequestToFileAtURLAsContentTypeCompletionHandler 

func (o *QLThumbnailGenerator) SaveBestRepresentationForRequestToFileAtURLAsContentTypeCompletionHandler(request *QLThumbnailGenerationRequest, fileURL *foundation.NSURL, contentType *uniformtypeidentifiers.UTType, completionHandler func(unsafe.Pointer))

Saves a thumbnail for the request on disk at fileURL. The file saved at fileURL has to be deleted when it is not used anymore. This is primarily intended for file provider extensions which need to upload thumbnails and have a small memory limit.
