\par \plain\f2\fs24\b Description:
|
||
\par \plain\f2\fs20
|
||
\par This class is a extension of a tree control
|
||
\par It has the following features:

\par \pard\plain\f2\fs20 \tab = dropdown combobox

\par COXTreeCtrl is derived from CListCtrl not from CTreeCtrl. That means that if you want to use dialog editor to create resource for your CDialog or CFormView derived class you have to use CListCtrl with "Report" and "OwnerDraw Fixed" style set. It also means that CListCtrl emulates CTreeCtrl functionality although not to full extent (see function reference for details). COXTreeCtrl lets you operate with standard structures and types that have to do with CTreeCtrl, but you still can use CListCtrl stuff to work with control (it could be useful feature if you really need to do some fancy stuff with COXTreeCtrl).
|
||
\par
|
||
\par Taking into account all mentioned above, this is not a big surprise that you have to use special technique to utilize COXTreeCtrl control. And all in all you possibly cannot do that just changing the name of class from CTreeCtrl to COXTreeCtrl. Below you will find description of common steps that you have to take to implement COXTreeCtrl in your application :

|
||
\par \pard\qc\plain\f2\fs20\b COXTreeCtrl with Dialog Resource
|
||
\par \pard\plain\f2\fs20
|
||
\par If you want to use it in a dialog or FormView and you are using dialog resource, then the best way is to create a list control , set up "Report" style and "OwnerDraw Fixed" style in resource editor and map it to COXTreeCtrl member variable (using subclassing or ClassWizard and DDX/DDV technique)

|
||
\par \pard\qc\plain\f2\fs20\b Initializing and populating of COXTreeCtrl
|
||
\par \pard\plain\f2\fs20 \tab
|
||
\par As soon as control is created you can populate it with columns, items and set different styles to make it look the way you want. You can insert and delete columns, items and subitems at any time after control's creation.
