We are using tooltip windows with icon size larger than 16x16. In this case, the tooltip window doesn’t show the icon correctly. In CExtPopupMenuTipWnd class,
HRGN CExtPopupMenuTipWnd::CalcRegion(
CDC & dc,
CSize * pSize // = NULL
)
{
...
...
...
CRect rcWnd = rcTextMeasure;
e_tip_style_t eTS = GetTipStyle();
switch( eTS )
{
case __ETS_BALLOON:
case __ETS_BALLOON_NO_ICON:
{
rcWnd.InflateRect( m_sizeRounders ); -->> PROBLEM IS HERE
if( eTS != __ETS_BALLOON_NO_ICON && (! m_icon.IsEmpty() ) )
{
rcWnd.right += m_sizeRenderingIcon.cx + m_nIconMarginDX;
if( rcWnd.Height() < m_sizeRenderingIcon.cy ) -->> PROBLEM IS HERE
rcWnd.bottom = rcWnd.top + m_sizeRenderingIcon.cy;
}
...
...
}
rcWnd.Height() never becomes smaller than m_sizeRenderingIcon.cy when the icon size is, for example, 24x24. Because the InflateRect functions makes rcWnd.top negative. The solution I found is to move the line
rcWnd.InflateRect( m_sizeRounders );
below
if( rcWnd.Height() < m_sizeRenderingIcon.cy )
rcWnd.bottom = rcWnd.top + m_sizeRenderingIcon.cy;
If I’m wrong please provide an exact solution for this problem. Thanks.
