Detailed Description

Builds widgets for nodes and wires their props and callbacks.

One per Mounted. It must outlive every scope it mounted into: a Switch, Tabs, Dialog, ForEach or Table binding calls back into it to mount content later.

Member Function Documentation

mount()

Widget * morph::ui::detail::Mounter::mount ( reactive::Scope & scope, Node const & node, ContainerWidget * parent )

inline

Mounts node under parent; scope owns its widgets and bindings.

A node's widget is adopted first, then its bindings, then its children, so destroying the scope destroys bindings before their widget and children before their parent.

Parameters

scope	Owns everything mounted.
node	The node; null mounts nothing.
parent	The container to append to, or null for a root.

Returns

The node's widget, or null for a null node.

Definition at line 228 of file mount.hpp.

mountRoot()

Widget * morph::ui::detail::Mounter::mountRoot ( reactive::Scope & scope, Node const & node, ContainerWidget * parent )

inline

Mounts node as mount does, as a mount of its own: the first autofocus widget it mounts, in document order, takes keyboard focus once the whole of it has mounted.

Parameters

scope	Owns everything mounted.
node	The node; null mounts nothing.
parent	The container to append to, or null for a root.

Returns

The node's widget, or null for a null node.

Definition at line 248 of file mount.hpp.

focus()

bool morph::ui::detail::Mounter::focus ( std::string_view focusId )

inline

Moves keyboard focus to the mounted widget whose focusId is focusId.

Of several such widgets (rows of a list), the one mounted first is taken. A backend that cannot move focus leaves it where it was; the request was still made.

Parameters

focusId

The name.

Returns

Whether a mounted widget has that name.
