Detailed Description

arranges components in a regular grid

The number of rows and columns is specified by the first two constructor parameters. If a number of rows is specified, the c parameter is ignored and the column number is calculated automatically. All components receive the same size. Inter-cell spacing may be controlled via the hgp and vgp ctor parameters. This layout manager ignores any constraint that is passed to its add function.

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

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