Detailed Description

Base class for widgets which can act as container and generator for widgets out of flow.

(Perhaps it should be diffenciated between the two roles, container and generator, but this would make multiple inheritance necessary.)

See Handling Elements Out Of Flow for an overview.

Requirements for sub classes (in most cases refer to dw::Textblock as a good example):

For both generators and containers of floats (which is only implemented by dw::Textblock) it gets a bit more complicated.

Todo:
Currently, on the level of dw::oof::OOFAwareWidget, nothing is done about dw::core::Widget::markSizeChange and dw::core::Widget::markExtremesChange. This does not matter, though: dw::Textblock takes care of these, and dw::Table is only connected to subclasses of dw::oof::OOFPositionedMgr, which do care about these. However, this should be considered for completeness.

void dw::oof::OOFAwareWidget::widgetRefSizeChanged ( int  externalIndex)

Called by an implementation of dw::oof::OutOfFlowMgr (actually only OOFPosRelMgr) for the generator of a widget out of flow, when the reference size has changed.

(The size of the reference is 0 * 0 for all other implementations of dw::oof::OutOfFlowMgr.)
