Trait containing all Grid methods.

Implementors

Grid

Provided Methods

fn add(&self, widget: &impl IsA<Widget>)

Add a Widget to the grid.

widget

a Widget the widget to add.

fn agree_to_close_async<P: FnOnce(Result<(), Error>) + 'static>( &self, cancellable: Option<&impl IsA<Cancellable>>, callback: P, )

Request to close, asynchronously. This will display the save dialog.

callback

callback called when ready

fn agree_to_close_future( &self, ) -> Pin<Box_<dyn Future<Output = Result<(), Error>> + 'static>>

fn foreach_frame<P: FnMut(&Frame)>(&self, callback: P)

Calls callback for each Frame within grid.

callback

a PanelFrameCallback

fn column(&self, column: u32) -> GridColumn

Gets the GridColumn for a column index.

column

a column index

Returns

a GridColumn

fn most_recent_column(&self) -> GridColumn

Gets the most recently acive column on a grid.

Returns

a GridColumn

fn most_recent_frame(&self) -> Frame

Gets the most recently acive frame on a grid.

Returns

a PanelGridFrame

fn n_columns(&self) -> u32

Gets the number of columns in the grid.

Returns

The number of columns.

fn insert_column(&self, position: u32)

Inserts a column at position.

position

The position to insert the column at.

fn connect_create_frame<F: Fn(&Self) -> Frame + 'static>( &self, f: F, ) -> SignalHandlerId

The “create-frame” signal is used to create a new frame within the grid.

Consumers of this signal are required to return an unrooted Frame from this signal. The first signal handler wins.

Returns

an unrooted Frame
