Implementations

impl FileBrowser

pub fn icon_size(&self) -> u32

Gets the icon size

pub fn set_icon_size(&mut self, s: u32)

Sets the icon size

pub fn set_filter(&mut self, pattern: &'static str)

Sets the filter for the FileBrowser. The following syntax is used for the pattern: * matches any sequence of 0 or more characters. ? matches any single character. [set] matches any character in the set. The set can contain any single characters, or a-z to represent a range. To match ] or -, they must be the first characters. To match ^ or !, they must not be the first characters. [^set] or [!set] matches any character not in the set. {X|Y|Z} or {X,Y,Z} matches any one of the subexpressions literally. \x quotes the character x so it has no special meaning. x all other characters must be matched exactly.

pub fn filter(&self) -> Option<String>

Gets the filter for the FileBrowser

pub fn filetype(&self) -> FileType

Gets the FileType of the FileBrowser

pub fn set_filetype(&mut self, t: FileType)
