Detailed Description

The abstract base class for layouts.

This is an abstract base class for layout elements whose main purpose is to define the position and size of other child layout elements. In most cases, layouts don't draw anything themselves (but there are exceptions to this, e.g. QCPLegend).

QCPLayout derives from QCPLayoutElement, and thus can itself be nested in other layouts.

QCPLayout introduces a common interface for accessing and manipulating the child elements. Those functions are most notably elementCount, elementAt, takeAt, take, simplify, removeAt, remove and clear. Individual subclasses may add more functions to this interface which are more specialized to the form of the layout. For example, QCPLayoutGrid adds functions that take row and column indices to access cells of the layout grid more conveniently.

Since this is an abstract base class, you can't instantiate it directly. Rather use one of its subclasses like QCPLayoutGrid or QCPLayoutInset.

For a general introduction to the layout system, see the dedicated documentation page The Layout System.

void QCPLayout::clear ( )

Removes and deletes all layout elements in this layout. Finally calls simplify to make sure all empty cells are collapsed.

See Also: remove, removeAt

void QCPLayout::clear ( )

virtual QCPLayoutElement* QCPLayout::elementAt ( int index ) const

pure virtual

Implemented in QCPLayoutInset, QCPLayoutInset, QCPLayoutInset, QCPLayoutInset, QCPLayoutInset, QCPLayoutGrid, QCPLayoutGrid, QCPLayoutGrid, QCPLayoutGrid, and QCPLayoutGrid.

virtual QCPLayoutElement* QCPLayout::elementAt ( int index ) const

pure virtual

Implemented in QCPLayoutInset, QCPLayoutInset, QCPLayoutInset, QCPLayoutInset, QCPLayoutInset, QCPLayoutGrid, QCPLayoutGrid, QCPLayoutGrid, QCPLayoutGrid, and QCPLayoutGrid.

QCPLayoutElement * QCPLayout::elementAt ( int index ) const

pure virtual

Returns the element in the cell with the given index. If index is invalid, returns 0.

Note that even if index is valid, the respective cell may be empty in some layouts (e.g. QCPLayoutGrid), so this function may return 0 in those cases. You may use this function to check whether a cell is empty or not.

See Also: elements, elementCount, takeAt

Implemented in QCPLayoutInset, QCPLayoutInset, QCPLayoutInset, QCPLayoutInset, QCPLayoutInset, QCPLayoutGrid, QCPLayoutGrid, QCPLayoutGrid, QCPLayoutGrid, and QCPLayoutGrid.

Returns a list of all child elements in this layout element. If recursive is true, all sub-child elements are included in the list, too.

Warning: There may be entries with value 0 in the returned list. (For example, QCPLayoutGrid may have empty cells which yield 0 at the respective index.)

Reimplemented from QCPLayoutElement.

Reimplemented in QCPLayoutGrid, QCPLayoutGrid, QCPLayoutGrid, QCPLayoutGrid, and QCPLayoutGrid.
