Virtual Developer Workshop: Containerized Development with Docker
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( &m_img, LVSIL_SMALL );
