Public Member Functions

virtual void setColumns (int columns)=0
 Sets the column count.
virtual void setGap (int gap)=0
 Sets the space between cells.
virtual void setSpan (Widget &child, int span)=0
 Sets how many columns a child spans; a child spans one until this is called.
virtual void setAlign (Align align)=0
 Places each cell's content vertically in its row. A new grid stretches it; a child's own alignSelf wins.
Public Member Functions inherited from morph::ui::ContainerWidget
virtual void moveChild (Widget &child, std::size_t index)=0
 Moves child to position index: it is removed, then inserted before the child now at index.
Public Member Functions inherited from morph::ui::Widget
 Widget (Widget const &)=delete
Widget & operator= (Widget const &)=delete
 Widget (Widget &&)=delete
Widget & operator= (Widget &&)=delete
virtual void setVisible (bool visible)=0
 Shows or hides the widget and everything inside it.
virtual void setEnabled (bool enabled)=0
 Enables or disables input on the widget and everything inside it.
virtual void setLayout (LayoutHints const &hints)=0
 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

◆ setColumns()

virtual void morph::ui::GridWidget::setColumns ( int columns)
pure virtual

Sets the column count.

Parameters
columnsAt least one.

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

◆ setGap()

virtual void morph::ui::GridWidget::setGap ( int gap)
pure virtual

Sets the space between cells.

Parameters
gapA spacing step, 0 to kMaxSpacingStep; the mount never passes another value.

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

◆ setSpan()

virtual void morph::ui::GridWidget::setSpan ( Widget & child,
int span )
pure virtual

Sets how many columns a child spans; a child spans one until this is called.

Parameters
childOne of this grid's children.
spanThe column count it occupies.

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

◆ setAlign()

virtual void morph::ui::GridWidget::setAlign ( Align align)
pure virtual

Places each cell's content vertically in its row. A new grid stretches it; a child's own alignSelf wins.

Parameters
alignWhere it sits.

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