SOLVED

If you override OnBeginLabelEdit in a class derived from XTPTreeBase you need to set the member variable m_htiEdit to the HTREEITEM of the item that is currently edited.

Codejock uses this member to determine if they paint the tree item in the normal colors or just plain white.

If the tree background color is not white the text drawn by the codejock tree control shows outside of the edit control created by the Windows tree control. If the text set in OnBeginLabelEdit is shorter than the text in the tree control.

If m_htiEdit is set to a HTREEITEM the OnPaint method in XTPTreeCtrl will not use the background color of the tree but white, which makes the extra text invisible next to the edit control.

Codejock should change the test in OnPaint to use m_pTreeCtrl->GetEditControl() to determine how to paint the tree text and not rely on the member variable m_htiEdit which is internal to Codejock and cannot be relied on.

Hi, Oleg

Yes, I can repro this bug in your sample. I just added an "OnBeginEdit" and set a label text shorter than what's in the tree. See screen shot. I've also attached the two modified files.

Hi,
Do you see it with attached sample:

void CSomeWnd::OnTvnBeginlabeledit(NMHDR *pNMHDR, LRESULT *pResult)
{
    LPNMTVDISPINFO ptv = reinterpret_cast<LPNMTVDISPINFO>(pNMHDR);
    // Do not allow by default
    *pResult = 1;

    CEdit* pedit = GetEditControl();
    if (pedit) {
        pedit->SetWindowText(_T("a"));
        *pResult = 0;
    }
}

If the text in the tree label was longer than "a" before, you will see the effect.

Oleg, this is clearly a bug in your code.


I just don't have the time in this project to create sample applications for you. If you carry out the steps I mentioned the problem will show. I have lost a half day today again because of the documentation of XTP is misleading, plain wrong or just not existing. I'm working against tight timelines here.

If you attach the test app you have used trying to repro this bug I can look it over. Just catch TVN_BEGINLABELEDIT in your code and set a shorter text than currently in the edit control.

Hi,
And I wrote few replies ago that can't reproduce it.

Oleg,

as I wrote, there is no need for a sample. I outlined the steps to reproduce several replies ago.

Hi, Oleg

no sample needed.  Just call EditLabel() on a tree item in an CXTTreeCtrl-derived class which also uses GetDispInfo to dynamically supply the label text.

Catch the TVN_BEGINLABELEDIT and set a shorter text than the current text in the label (what the user can edit must not be the same what is displayed later in the tree).

E.g. The label currently shows "Some longer label" and in BeginEdit you set the text "Test" for the label. This produces the effect I mentioned.
