Recently, in one of my projects, I needed a
CListCtrl derived class which has the ability to show/hide its columns dynamically. Using
CListCtrl::DeleteColumn() is not a good idea because in that case the index of the sub items will be changed from time to time, thus assessing the sub items will become very complicated. I searched the Internet and did not find an existing solution for this. At last, I had to write my own class -
CListCtrlEx to implement the feature.
The main features of CListCtrlEx
- Dynamically hide/show the columns.
- Provide a built-in context menu to select the columns and it is dynamically created based on the columns you insert.
- Drag-and-drop reorder columns (you must enable the
- Save/restore the columns' order, width and visibility in/from registry automatically.
- You do not need to change your existing code of
CListCtrl derived classes. All you have to do is change their base class to
Using the CListCtrlEx class
- Add the following files to your project:
- Import the following two cursor files into you resource and change their ID as mentioned in the square brackets:
- res\VE_SPLIT.CUR [
- res\VE_SIZEB.CUR [
- Derive your own class, say
- Add a list control to your dialog in the resource editor and bind it to a member variable, say
m_wndList. Of course the variable should be a
void CTestListCtrlDlg::DoDataExchange(CDataExchange* pDX)
DDX_Control(pDX, IDC_LIST, m_wndList);
- Save/restore the state of the columns.
