How do you move a treenode from one place to another
without dragging the node? For example, move it with
the click of a button.
Thanks! |

Have you looked at the TTreeNode::MoveTo() method yet?

Great I got it, what was confusing me was how to get a checked
node, and move that node to the selected node. This code seems
to work while testing.
TreeView1->Items->Item[36]->MoveTo(TreeView1->Selected,
naAddChildFirst);
Thanks. |

Seems I may have jumped the gun too quickly. I am adding
checkboxes in my treeview via this code.
#ifndef TVS_CHECKBOXES
#define TVS_CHECKBOXES 0x0100
#endif
DWORD dwStyle = GetWindowLong(TreeView1->Handle, GWL_STYLE);
dwStyle = dwStyle | TVS_CHECKBOXES | TVS_SHOWSELALWAYS;
SetWindowLong(TreeView1->Handle, GWL_STYLE, dwStyle);
I am not getting the concept of getting all the checked nodes and
moving them
to the node that I am selected on.
I am trying to iterate the tree with some simple code.
TTreeNode *Node = TreeView1->Items->GetFirstNode();
while(Node)
{
TreeView1->Items->Item[]->MoveTo(TreeView1->Selected,
naAddChildFirst);
Node = Node->GetNext();
}
Kinda stuck.... |

That is because your code is wrong to begin with. You are not querying the
checked status of each node at all, and you are not looping through the
nodes correctly anyway.
Use this instead:
bool __fastcall NodeIsChecked(TTreeNode *Node)
{
TVITEM tvItem = {0};
tvItem.mask = TVIF_HANDLE | TVIF_STATE;
tvItem.hItem = Node->ItemId;
tvItem.stateMask = TVIS_STATEIMAGEMASK;
TreeView_GetItem(Node->Handle, &tvItem);
return ((tvItem.state >> 12) - 1);
}
{
TTreeNode *Selected = TreeView1->Selected;
if( Selected )
{
TTreeNode *Node = TreeView1->Items->GetFirstNode();
TTreeNode *Next;
while( Node )
{
Next = Node->GetNext();
if( NodeIsChecked(Node) && (Node != Selected) )
Node->MoveTo(Selected, naAddChildFirst);
Node = Next;
}
}
}
