Descripción detallada

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.

Documentación del constructor y destructor

QCPLayout::QCPLayout ( )

explicit

Creates an instance of QCPLayoutElement and sets default values. Note that since QCPLayoutElement is an abstract base class, it can't be instantiated directly.

Documentación de las funciones miembro

void QCPLayout::clear ( )

Removes and deletes all layout elements in this layout.

Ver también: remove, removeAt

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.

int QCPLayout::elementCount ( ) const

pure virtual

Returns the number of elements/cells in the layout.

Ver también: elements, elementAt

Implementado en QCPLayoutInset y QCPLayoutGrid.

QList< QCPLayoutElement * > QCPLayout::elements ( bool recursive ) const

virtual

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.

Note that 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.)

bool QCPLayout::remove ( QCPLayoutElement * element )

Removes and deletes the provided element. Returns true on success. If element is not in the layout, returns false.

This function internally uses takeAt to remove the element from the layout and then deletes the element.

Ver también: removeAt, take

bool QCPLayout::removeAt ( int index )

Removes and deletes the element at the provided index. Returns true on success. If index is invalid or points to an empty cell, returns false.

This function internally uses takeAt to remove the element from the layout and then deletes the returned element.

Ver también: remove, takeAt

void QCPLayout::simplify ( )

virtual

Simplifies the layout by collapsing empty cells. The exact behavior depends on subclasses, the default implementation does nothing.

Not all layouts need simplification. For example, QCPLayoutInset doesn't use explicit simplification while QCPLayoutGrid does.

Reimplementado en QCPLayoutInset y QCPLayoutGrid.

void QCPLayout::sizeConstraintsChanged ( ) const

protected

Subclasses call this method to report changed (minimum/maximum) size constraints.

If the parent of this layout is again a QCPLayout, forwards the call to the parent's sizeConstraintsChanged. If the parent is a QWidget (i.e. is the QCustomPlot::plotLayout of QCustomPlot), calls QWidget::updateGeometry, so if the QCustomPlot widget is inside a Qt QLayout, it may update itself and resize cells accordingly.

bool QCPLayout::take ( QCPLayoutElement * element )

pure virtual

Removes the specified element from the layout and returns true on success.

If the element isn't in this layout, returns false.

Note that some layouts don't remove the respective cell right away but leave an empty cell after successful removal of the layout element. To collapse empty cells, use simplify.

Ver también: takeAt

Implementado en QCPLayoutInset y QCPLayoutGrid.

QCPLayoutElement * QCPLayout::takeAt ( int index )

pure virtual

Removes the element with the given index from the layout and returns it.

If the index is invalid or the cell with that index is empty, returns 0.

Note that some layouts don't remove the respective cell right away but leave an empty cell after successful removal of the layout element. To collapse empty cells, use simplify.

Implementado en QCPLayoutInset y QCPLayoutGrid.

void QCPLayout::update ( )

virtual

First calls the QCPLayoutElement::update base class implementation to update the margins on this layout.

Then calls updateLayout which subclasses reimplement to reposition and resize their cells.

Finally, update is called on all child elements.
