C++ (Cpp) clearAnchors Examples

Example #1

File: SwitchNode.cpp Project: jgrande/ginga

void SwitchNode::clearNodes() {
	while (nodes->size() > 0) {
		removeNode( nodes->size() - 1 );
	}
	setDefaultNode( NULL );
	clearAnchors();
	clearPorts();
}

Example #2

File: grid_helper.cpp Project: JOE-JOE-NGIGI/kicad

VECTOR2I GRID_HELPER::BestSnapAnchor( const VECTOR2I& aOrigin, BOARD_ITEM* aDraggedItem )
{
    double worldScale = m_frame->GetGalCanvas()->GetGAL()->GetWorldScale();
    int snapRange = (int) ( 100.0 / worldScale );

    BOX2I bb( VECTOR2I( aOrigin.x - snapRange / 2, aOrigin.y - snapRange / 2 ), VECTOR2I( snapRange, snapRange ) );

    clearAnchors();

    BOOST_FOREACH( BOARD_ITEM* item, queryVisible( bb ) )
    {
        computeAnchors( item, aOrigin );
    }

Example #3

File: grid_helper.cpp Project: JOE-JOE-NGIGI/kicad

{
    clearAnchors();
