pub struct OpenButton { /* private fields */ }
Expand description

Open button component.

Creates a button with custom text that can be used to open a file chooser dialog. If a file is chosen, then it will be emitted as an output. The component can also optionally display a popover list of open files if OpenButtonSettings::recently_opened_files is set to a value.

Implementations§

source§

impl OpenButton

source

pub fn track_all() -> u8

Get a bit mask to look for changes on all fields.

source

pub fn mark_all_changed(&mut self)

Mark all fields of the struct as changed.

source

pub fn changed(&self, mask: u8) -> bool

Check for changes made to this struct with a given bitmask.

To receive the bitmask, simply call Type::#field_name() or Type::#track_all();

source

pub fn reset(&mut self)

Resets the tracker value of this struct to mark all fields as unchanged again.
