Previously, some people often asked how to save the contents edited in Treectrl, although CodeGuru has a related article, but someone else said.
First, this TreeEList should use the TVS_EDitlabels style, specify when creating resources, or specify when using CREATE, or change in PrecreateWindos (). My code is: const DWORD dwViewStyle = WS_CHILD | WS_VISIBLE | TVS_HASLINES | TVS_LINESATROOT | TVS_HASBUTTONS | TVS_EDITLABELS; if (m_wndTree1.Create (dwViewStyle, rectDummy, & m_wndTabs, 2) || m_wndTree2.Create (dwViewStyle, rectDummy, & m_wndTabs, 3!! )) {Trace0 ("failed to create workspace view / n"); return -1; // fail to create}
The red part is the key! This way you can edit your title by now TreeItem!
Next, you need to handle TVN_BEGINLABELEDIT and TVN_ENDLABELEDIT messages.
Void CMYTREE: ONBEGINLABELEDIT (NMHDR * PNMHDR, LRESULT * PRESULT)
{
Tv_dispinfo * ptvdispinfo = (TV_Dispinfo *) PNMHDR;
// limited text length
GetEditControl () -> LimitText (127);
* PRESULT = 0;
}
If the TVN_ENDLABELEDIT message is not processed, the changes in text will not take effect. Void coutline :: Onendlabeledit (NmHDR * pnmhdr, lresult * presult) - {getEtTControl () -> getWindowText (s); // set result to true to accept the change:} Note: The above code is from Sens Ocean "uses the EDIT function in Treelist"
Here, you can create a category, cmytree, then add TVN_BEGINLABELEDIT and TVN_ENDLABELEDIT messages through ClassWizard
ClassWizard's code for us is:
protected: // {{AFX_MSG (CMyTree) afx_msg void OnBeginlabeledit (NMHDR * pNMHDR, LRESULT * pResult); afx_msg void OnEndlabeledit (NMHDR * pNMHDR, LRESULT * pResult); //}} AFX_MSG
Ok, you can edit it by TreeItem, you can edit it! Oh, the younger brother first post, I also hope that everyone will bear.
