Ctreectrl hittest usage

The hittest function of ctreectrl can obtain the items related to the current mouse position.

This function can be implemented. In the tree with a checkbox, the checkbox of the parent node is selected, and the checkbox of the child node can be automatically selected. Because the htreeitem of the parent node can be obtained, the child nodes can be traversed based on this attribute.

Void cmydlg: onnmclicktree1 (nmhdr * pnmhdr, lresult * presult)
{

Cpoint pt;
Uint nflags;
: Getcursorpos (& pt );
: Screentoclient (m_ctree.m_hwnd, & pt );
Htreeitem hitem = m_ctree.hittest (PT, & nflags );

Cstring smsg;
Smsg. Format (_ T ("% s"), m_ctree.getitemtext (hitem ));
Afxmessagebox (smsg );
