21.3.5..Views Transition..................................................................................

You can create a list control that displays its items in a single view or you can allow the

user to change from one view to another. As mentioned already, at design time or when

programmatically creating the list control, you can set the initial view using either the

View combo box to select a view’s value or by adding one of the view styles. If you want

to display only that initial view, you can stop there. Otherwise, you can provide a means

of changing views.

Because the view displayed on a list control is part of its style, in order to

programmatically change its view mode, you can first retrieve the control’s style using

the GetWindowLong() function. The GetWindowLong() function only retrieves the

current style of the control. You may need to check it first before changing it. This can be

done by ANDing the value of the GetWindowLong() function with the

LVS_TYPEMASK constant. After checking the view of the control, you can then

change its style by calling the SetWindowLong() function. Here is an example:

void COthersDlg::OnIconBtn()

{

// TODO: Add your control notification handler code here

LONG mListStyle = GetWindowLong(m_List.m_hWnd, GWL_STYLE);

mListStyle &= ~LVS_TYPEMASK;

mListStyle |= LVS_ICON;

SetWindowLong(m_List.m_hWnd, GWL_STYLE, mListStyle);

}
