Detailed Description

An NCPad for an NCTree.

Most of its former functionality is now handled in the NCTablePadBase base class.

Member Function Documentation

Destwin()

void NCTreePad::Destwin ( NCursesWindow * dwin )

virtual

Parameters

dwin	(not owned)

Reimplemented from NCPad.

DoRedraw()

int NCTreePad::DoRedraw ( )

protectedvirtual

Redraw the pad.

Reimplemented from NCTablePadBase and NCPad.

Reimplemented from NCTablePadBase.

handleInput()

bool NCTreePad::handleInput ( wint_t key )

virtual

Handle a keyboard input event. Return 'true' if the event is now handled, 'false' if it should be propagated to the parent widget.

Most of the keys are now handled in the NCTablePadBase base class or in the individual items' handlers (NCTreeLine, NCTableLine). This method is mostly here as a stub for future extensions.

Reimplemented from NCTablePadBase and NCPad.

Reimplemented from NCTablePadBase.
