 Enables or disables input on the widget and everything inside it.

 Sets the size request.
virtual void setDragKey (std::optional< Key > const &key)=0
 Makes the widget draggable, carrying key, or not draggable.
virtual void setDropHandler (std::function< bool(Key const &)> accepts, std::function< void(Key)> onDrop)=0
 Makes the widget a drop target.
virtual void setAccessibleName (std::string_view name)=0
 Sets the name assistive technology reads for the widget.
virtual void setAccessibleRole (std::string_view role)=0
 Sets the role assistive technology announces for the widget.
virtual void setTestId (std::string_view testId)=0
 Sets the stable identifier an automated test finds the widget by.
virtual void setTooltip (std::string_view text)=0
 Sets the text shown while the pointer rests on the widget.
virtual void setSurface (std::string_view surface)=0
 Styles the widget and everything inside it with a named token set of the theme.
virtual void setKeys (std::vector< std::string > const &chords, std::function< void(std::string)> onChord)=0
 Declares the keyboard chords the widget handles while focus is inside it.
virtual void focus ()=0
 Moves keyboard focus to the widget.
virtual void setOnHover (std::function< void()> onHover)
 Calls onHover each time the pointer comes to rest over the widget. A backend without a pointer, or one that does not report hovering, keeps the default, which never calls it: hovering is a hint, such as a prefetch, never something a widget relies on.

Member Function Documentation

◆ setItems()

virtual void morph::ui::MenuWidget::setItems ( std::vector< MenuEntry > const & entries)
pure virtual

Replaces the entries.

Parameters
entriesThe entries, in order, each with its submenu.

Implemented in morph::ui::testing::detail::FakeMenu.

◆ setOnActivate()

virtual void morph::ui::MenuWidget::setOnActivate ( std::function< void(std::vector< std::size_t >)> onActivate)
pure virtual

Sets what choosing an entry calls, with its path.

Only an enabled entry without a submenu, inside enabled entries, can be chosen.

Parameters
onActivateThe handler, given the entry's index at each level from the top; empty does nothing.

Implemented in morph::ui::testing::detail::FakeMenu.
