CListBox::GetItemHeight
Determines the height of items in a list box.
int GetItemHeight(
int nIndex
) const;
Parameters
- nIndex
Specifies the zero-based index of the item in the list box. This parameter is used only if the list box has the LBS_OWNERDRAWVARIABLE style; otherwise, it should be set to 0.
Return Value
The height, in pixels, of the items in the list box. If the list box has the LBS_OWNERDRAWVARIABLE style, the return value is the height of the item specified by nIndex. If an error occurs, the return value is LB_ERR.
Example
// Set the height of every item so the item
// is completely visible.
CString str;
CSize sz;
CDC* pDC = m_myListBox.GetDC();
for (int i=0;i < m_myListBox.GetCount();i++)
{
m_myListBox.GetText( i, str );
sz = pDC->GetTextExtent(str);
// Only want to set the item height if the current height
// is not big enough.
if (m_myListBox.GetItemHeight(i) < sz.cy)
m_myListBox.SetItemHeight( i, sz.cy );
}
m_myListBox.ReleaseDC(pDC);
