Implemented Interfaces

HdyComboRow implements AtkImplementorIface, GtkBuildable and GtkActionable.

Description

The HdyComboRow widget allows the user to choose from a list of valid choices. The row displays the selected choice. When activated, the row displays a popover which allows the user to make a new choice.

The HdyComboRow uses the model-view pattern; the list of valid choices is specified in the form of a GListModel, and the display of the choices can be adapted to the data in the model via widget creation functions.

HdyComboRow is “activatable” if a model is set.

CSS nodes

HdyComboRow has a main CSS node with name row.

Its popover has the node name popover with the .combo style class, it contains a GtkScrolledWindow, which in turn contains a GtkListBox, both are accessible via their regular nodes.

A checkmark of node and style class image.checkmark in the popover denotes the current item.
