FlowBoxRef

public struct FlowBoxRef : FlowBoxProtocol, GWeakCapturing

A GtkFlowBox puts child widgets in reflowing grid.

For instance, with the horizontal orientation, the widgets will be arranged from left to right, starting a new row under the previous row when necessary. Reducing the width in this case will require more rows, so a larger height will be requested.

Likewise, with the vertical orientation, the widgets will be arranged from top to bottom, starting a new column to the right when necessary. Reducing the height will require more columns, so a larger width will be requested.

The size request of a GtkFlowBox alone may not be what you expect; if you need to be able to shrink it along both axes and dynamically reflow its children, you may have to wrap it in a GtkScrolledWindow to enable that.

The children of a GtkFlowBox can be dynamically sorted and filtered.

Although a GtkFlowBox must have only GtkFlowBoxChild children, you can add any kind of widget to it via [methodGtk.FlowBox.insert], and a GtkFlowBoxChild widget will automatically be inserted between the box and the widget.

GtkFlowBox uses a single CSS node with name flowbox. GtkFlowBoxChild uses a single CSS node with name flowboxchild. For rubberband selection, a subnode with name rubberband is used.

Accessibility

GtkFlowBox uses the GTK_ACCESSIBLE_ROLE_GRID role, and GtkFlowBoxChild uses the GTK_ACCESSIBLE_ROLE_GRID_CELL role.

The FlowBoxRef type acts as a lightweight Swift reference to an underlying GtkFlowBox instance. It exposes methods that can operate on this data type through FlowBoxProtocol conformance. Use FlowBoxRef only as an unowned reference to an existing GtkFlowBox instance.

  • ptr
    Untyped pointer to the underlying `GtkFlowBox` instance.
    

    For type-safe access, use the generated, typed pointer flow_box_ptr property instead.

    Declaration

    Swift

    public let ptr: UnsafeMutableRawPointer!
