Although icons always have to be a square, the images we use in the list view control does not. For instance, the following code will create images that are 62 pixels wide. The height of the image will be the same as the bitmap height in the resource. m_img.Create( IDB_CUSTOMBITMAP, 62, 1, (COLORREF)-1 );   m_listctrl.SetImageList( […]

Although we can use a bitmap with the header control and specify a bitmap for each item in the header individually, there are two benefits of using an image list instead. The first is that the images can be drawn transparently ( and a few other effects ) and the second is that you can […]

A system image list contains each file, folder, shortcut, etc. ‘s icon.  This can come  in very handy for creating a custom explore type application.  The first step consists of getting the small and large (if you want it) image lists from the system then attaching them to a CImageList and then adding them  to […]

The image for an item can be set when an item is first added to the list view control. m_listctrl.InsertItem( LVIF_TEXT | LVIF_IMAGE, nRow, sItemText, 0, 0, nImage, NULL); The image can later be changed by calling the SetItem() function. The CListCtrl class does not have a SetImage() function. m_listctrl.SetItem( 0, 0, LVIF_IMAGE, NULL, nImage, […]

When inserting an item in the list view control, you dont have to specify the image just then. You can delay a decision on the image by using a callback item. A callback item is an item that causes the list view control to send the LVN_GETDISPINFO notification to its parent whenever it needs information […]

CToolTipCtrl m_tooltip; Step 2: Create the tooltip object Override PreSubclassWindow() in your CListCtrl derived class. After calling the base class PreSubclassWindow(), create the tooltip object. We override the PreSubclassWindow() instead of OnCreate() because the control is usually attached to the C++ object after it has already been created – usually from a dialog resource – […]

Tooltips are very useful when column widths are limited due to limited screen size. They could also be used to expand the text of abreviated columns. For this task, we will use the tooltip support provided by MFC. The code below displays the text of the cell in a tooltip, but it can be easily […]

To implement titletips we define a custom class for the titletip. This class is responsible for displaying the tips when needed. Within the mouse move handler of the listview control we simply call a member function of the CTitleTip object with the cell rectangle and the text to display within it. The CTitleTip object then […]

Adding a tooltip for the header control is quite straightforward. We use a tooltip control object and add a tool for the header control Step 1: Add member of type CToolTipCtrl Add a member variable of type CToolTipCtrl in your CListCtrl derived class. CToolTipCtrl m_tooltip; Step 2: Initialize the tooltip object Override PreSubclassWindow() in your […]

This code was contributed by Mark Findlay. // This is a simple modification of the text sorting routine by // Zafir Anjum. (See “Sorting the list based on text in any column”) // // It sorts the list based on the image index of the column being // sorted. You must only call this function […]

bool CMyListCtrl::SortNumericItems( int nCol, BOOL bAscending,int low/*=0*, int high/*=-1* ) { if( nCol >= ((CHeaderCtrl*)GetDlgItem(0))->GetItemCount() ) return FALSE; if( high == -1 ) high = GetItemCount() – 1; int lo = low; int hi = high; int midItem; if( hi <= lo ) return FALSE; midItem = atoi(GetItemText( (lo+hi)/2, nCol )); // loop through the […]

This code is based on the articls “Sorting the list based on text in any column” & “Sorting list on Numeric Column”. The follwing code combines both articals and adds a new sort type Date/Time sort. #include // MFC Ole #include // Ole TimeData something… Add function // Compare two string by their column types […]
