Constructor & Destructor Documentation

Member Function Documentation

GtkTreeIter* VDKTreeViewModelIterator::current (    )  [inline]

return node presently visited

bool VDKTreeViewModelIterator::HasChild (    )

Returns true if presently visited node has a child. TIP: Since iterator incremental operator skips on next sibling node, you can use this to visit all tree nodes on depth-first strategy using recursion. See example below taken from /testvdk/treeviewcompo.cc: void TreeViewComponent::recurse(GtkTreeIter* iter) { VDKTreeViewModel* model = tree->Model; VDKTreeViewModelIterator ti(model,iter); for(;ti;ti++) { PrintRow(ti.current()); // uses presently pointed node if(ti.HasChild()) recurse (ti.current()); } } bool TreeViewComponent::OnTrasverseClicked (VDKObject* sender) { recurse(NULL); return true; }

VDKTreeViewModelIterator::operator int (    )  [inline]

Returns true if presently visited node is valid

void VDKTreeViewModelIterator::operator++ (  int    )

Incremental operator (infix), visit next sibling node

void VDKTreeViewModelIterator::operator++ (    )

Incremental operator (postfix), visit next sibling node
