Detailed Description

arranges components in a row or a column

Depending on the values passed to the constructor, components are laid out horizontally (in a row) or vertically (in a column), aligned as specified and with an inter-component space of gp. If the container using this manager offers enough space, components receive their preferred size. Otherwise, they are scaled down according to their respective requests. This layout manager ignores any constraint passed to its add function.

Member Function Documentation

void ONE::gui::StackLayout::add (  Component *  , const LayoutConstraint *  )  [virtual]

adds a component to be laid out later The components are only modified when LayoutManager::layout is called. Parameters: comp  the component cons  a constraint object which helps the layout manager determine the component's placement Implements ONE::gui::LayoutManager.

void ONE::gui::StackLayout::layout (  Widget *  , const Bounds &  )  [virtual]

lays out the given object This function will rearrange and resize obj 's content to fit inside inner according to this LayoutManager 's layout strategy. Parameters: obj  the object that will be laid out inner  obj 's inner bounds Implements ONE::gui::LayoutManager.

Size ONE::gui::StackLayout::preferredLayoutSize (  const Widget *   )  const [virtual]

calculates the preferred size for the given object The size is calculated based on this layout manager's layout strategy and the content's preferred sizes. Note, hovever, that this function does not check for the presence of a border around obj. Parameters: obj  the target of the operation Returns: the optimal size for obj Implements ONE::gui::LayoutManager.

void ONE::gui::StackLayout::remove (  Component *   )  [virtual]

removes a component Parameters: comp  the component Implements ONE::gui::LayoutManager.
