Detailed Description

A layout manager which spans a single widget to all available space.

This layout manager may manage only a single child widget, and sizes that widget so that it uses all space available in the parent.

Note:
This layout manager is applicable only to Ext::Container container widgets. If you wish to fit widgets within a container widgets, use a WBoxLayout instead (with a single child).

void Wt::WFitLayout::addItem ( WLayoutItem item) [virtual]

Adds a layout item.

The item may be a widget or nested layout.

How the item is layed out with respect to siblings is implementation specific to the layout manager. In some cases, a layout manager will overload this method with extra arguments that specify layout options.

removeItem(WLayoutItem *), addWidget(WWidget *)

Implements Wt::WLayout.

int Wt::WFitLayout::count ( ) const [virtual]

Returns the number of items in this layout.

This may be a theoretical number, which is greater than the actual number of items. It can be used to iterate over the items in the layout, in conjunction with itemAt().

Implements Wt::WLayout.

int Wt::WFitLayout::indexOf ( WLayoutItem item) const [virtual]

Returns the index of a given item.

The default implementation loops over all items, and returns the index for which itemAt(index) equals item.

See also:
itemAt(int) const

Reimplemented from Wt::WLayout.

WLayoutItem * Wt::WFitLayout::itemAt ( int  index) const [virtual]

Returns the layout item at a specific index.

If there is no item at the index, 0 is returned.

indexOf(WLayoutItem *) const, count()

Implements Wt::WLayout.

void Wt::WFitLayout::removeItem ( WLayoutItem item) [virtual]

Removes a layout item (widget or nested layout).

addItem(WLayoutItem *), removeWidget(WWidget *)
