TreeListCtrl In CView With Tool Tips

Posted by Gary Andrew Lewis on January 13th, 2003

Environment: VC6, MFC

This project was written to provide you with a Tree List to put on any CView. It supports images, checkboxes, and all the functionality of both CTree and CList Controls. It automatically resizes itself when the user changes the window that has been attached to it. Clicking on the List Header will sort the tree either in ascending or descensding order. Each cell is also editable and can have either an edit box or a combo box for this purpose.

Just have a look at the accompanying code; if you have any problems, don't hesitate to e-mail me. All source code is provided in zips below. Just download and enjoy!

  • Change the text color of a subitem

    Posted by catia_wapf on 08/03/2006 08:38am

    How can I change the textcolor of a specific subitem of a tree item? I have a tree list with 5 columns and one of them is called "Priority". Each priority item in this column should have a specific text color. How can I do that? How can I change the text color of a subitem? Thanks a lot. Regards Catia

  • Bug solution when you double click outside the tree

    Posted by Legacy on 05/16/2003 12:00am

    Originally posted by: Bogdan BRINZAREA 

     I found out a small bug in the function that handles the 

    double click action. If the double click is outside the

    tree area, below the tree the program generates an error.

    This is because the program tries to handle the message

    for a tree item that doesn't exist.

    The solution is:

    void CTreeListCtrl::OnLButtonDblClk(UINT nFlags, CPoint point) 

    {

    	

    	if((GetColumnsNum()==0) || (point.x<GetColumnWidth(0)))

    	{

    		CTreeCtrl::OnLButtonDblClk(nFlags, point);

    		ResetVertScrollBar();

    	}

    	

    	SetFocus();	

    	

    	m_selectedItem = HitTest(point, &nFlags);

    	//verify that there is an item selected 

    	if(m_selectedItem!=NULL)

    		ShowEditComboBoxes(point);	

    }

    They atleast took the time and effort to contribute.
    the least you can do is take what they offer, and use it
    it you can, if you can't just move on.

    What do you have to contribute?
