Constants ¶
const URIRootError uriRootError = uriRootError("Cannot take the parent of the root element in a URI")
URIRootError should be thrown by fyne.URI implementations when the caller attempts to take the parent of the root. This way, downstream code that wants to programmatically walk up a URIs parent's will know when to stop iterating.

Functions ¶
func Child ¶ added in v1.4.0
Child appends a new path element to a URI, separated by a '/' character.
Since: 1.4
func Exists ¶ added in v1.4.0
Exists will return true if the resource the URI refers to exists, and false otherwise. If an error occurs while checking, false is returned as the first return.
Since: 1.4
func ListerForURI ¶ added in v1.4.0
func ListerForURI(uri fyne.URI) (fyne.ListableURI, error)
ListerForURI will attempt to use the application's driver to convert a standard URI into a listable URI.
Since: 1.4
func LoadResourceFromURI ¶ added in v1.4.1
LoadResourceFromURI creates a new StaticResource in memory using the contents of the specified URI. The URI will be opened using the current driver, so valid schemas will vary from platform to platform. The file:// schema will always work.
func NewFileURI ¶ added in v1.4.0
NewFileURI creates a new URI from the given file path.
func NewURI ¶
NewURI creates a new URI from the given string representation. This could be a URI from an external source or one saved from URI.String()
func OpenFileFromURI ¶
func OpenFileFromURI(uri fyne.URI) (fyne.URIReadCloser, error)
OpenFileFromURI loads a file read stream from a resource identifier. This is mostly provided so that file references can be saved using their URI and loaded again later.
func Parent ¶ added in v1.4.0
Parent gets the parent of a URI by splitting it along '/' separators and removing the last item.
Since: 1.4
func SaveFileToURI ¶
func SaveFileToURI(uri fyne.URI) (fyne.URIWriteCloser, error)
SaveFileToURI loads a file write stream to a resource identifier. This is mostly provided so that file references can be saved using their URI and written to again later.
Types ¶
type ExtensionFileFilter ¶
type ExtensionFileFilter struct {
Extensions []string
}
ExtensionFileFilter represents a file filter based on the the ending of file names, for example ".txt" and ".png".
type FileFilter ¶
FileFilter is an interface that can be implemented to provide a filter to a file dialog.
func NewExtensionFileFilter ¶
func NewExtensionFileFilter(extensions []string) FileFilter
NewExtensionFileFilter takes a string slice of extensions with a leading . and creates a filter for the file dialog. Example: .jpg, .mp3, .txt, .sh
func NewMimeTypeFileFilter ¶
func NewMimeTypeFileFilter(mimeTypes []string) FileFilter
NewMimeTypeFileFilter takes a string slice of mimetypes, including globs, and creates a filter for the file dialog. Example: image/*, audio/mp3, text/plain, application/*
type MimeTypeFileFilter ¶
type MimeTypeFileFilter struct {
MimeTypes []string
}
MimeTypeFileFilter represents a file filter based on the files mime type, for example "image/*", "audio/mp3".
