IsIconic到底怎么用

[abc3240666]

void CtestDlg::OnPaint()
{
if (IsIconic())
{
CPaintDC dc(this); // device context for painting

SendMessage(WM_ICONERASEBKGND, reinterpret_cast<WPARAM>(dc.GetSafeHdc()), 0);

// 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);
}
else
{
CDialog::OnPaint();
}
}

Dialog的右上角已经添加了最大化和最小化按钮了
为什么最小化时，IsIconic死活都是FALSE，究竟是神马情况啊？

在工程的其他地方想通过IsIconic来判断也是总是FALSE，郁闷啊。

void CXXDlg::OnTimer(UINT_PTR nIDEvent)
{
// TODO: 在此添加消息处理程序代码和/或调用默认值
if (IsIconic())
{
MessageBox(L"Iconic!");
KillTimer(1);
}
CDialogEx::OnTimer(nIDEvent);
}

[/Quote]IsIconic跟Timer有啥关系呢？放哪不都一样么？

//The following example attaches an HWND to the CWindow object and
//calls CWindow::IsIconic() to determine if the window is minimized

CWindow myWindow;
myWindow.Attach(hWnd);
BOOL bIconic = myWindow.IsIconic();

这样做的话，只有在发生重绘的时候才会弹出MessageBox，否则最小化后，什么都不操作的话，不会弹出来提示框的
