March 21st, 2007
CWnd::IsIconic
BOOL IsIconic( ) const;
Return Value
Nonzero if CWnd is minimized; otherwise 0.
Remarks
Specifies whether CWnd is minimized (iconic).
Example
// This code, normally emitted by the AppWizard for a dialog-based
// project for the dialog's WM_PAINT handler, runs only if the
// window is iconic. The window erase the icon's area, then
// paints the icon referenced by m_hIcon.
if (IsIconic())
{
CPaintDC dc(this); // device context for painting
IconEraseBkgnd(dc);
// Center icon in client rectangle
int cxIcon = GetSystemMetrics(SM_CXICON);
int cyIcon = GetSystemMetrics(SM_CYICON);
CRect rect;
GetClientRect(&rect);
int x = (rect.Width() - cxIcon + 1) / 2;
int y = (rect.Height() - cyIcon + 1) / 2;
// Draw the icon
dc.DrawIcon(x, y, m_hIcon);
}
// project for the dialog's WM_PAINT handler, runs only if the
// window is iconic. The window erase the icon's area, then
// paints the icon referenced by m_hIcon.
if (IsIconic())
{
CPaintDC dc(this); // device context for painting
IconEraseBkgnd(dc);
// Center icon in client rectangle
int cxIcon = GetSystemMetrics(SM_CXICON);
int cyIcon = GetSystemMetrics(SM_CYICON);
CRect rect;
GetClientRect(&rect);
int x = (rect.Width() - cxIcon + 1) / 2;
int y = (rect.Height() - cyIcon + 1) / 2;
// Draw the icon
dc.DrawIcon(x, y, m_hIcon);
}
