Will you please clarify what do you mean by "the window would not smooth."
Are you using RedrawWindow() in your code many a times?

First of all try to remove RedrawWindow() where you don't need them and then work with setting flags for RedrawWindow
BOOL RedrawWindow(
HWND hWnd, // handle to window
CONST RECT *lprcUpdate, // update rectangle
HRGN hrgnUpdate, // handle to update region
UINT flags // array of redraw flags /// Try using a combination
);

but all RedrawWindow are needed.......something can better replace RedrawWindow???
|

Try experimenting with the flag values in the RedrawWindow Function.

A WORD is a 16 bit unsigned integer. use %u for that

hi,
"%d" -> Signed integers
"%u" -> UnSigned integers
as BYTE is unsigned type use "%u"

I create a CMyButton and handled WM_SIZE
void CMyButton::OnSize(...)<br />
{<br />
CButton::OnSize(...);<br />
<br />
CRect rect;<br />
GetClientRect(rect);<br />
<br />
m_rgn.DeleteObject(); <br />
SetWindowRgn(NULL, FALSE);<br />
m_rgn.CreateEllipticRgnIndirect(rect);<br />
SetWindowRgn(m_rgn, TRUE);<br />
<br />
}
But when the button size changed, round size not change, why?
Thanks.

"Need to change the values in the rect" how to do?
|
|
|
|
|
rect.top = 20; etc . Do likewise for rect.left,rect.right,rect.bottom

i want "when button size is changed, the round size same with button size"
|
|
|
|

Instead of the code that you are writing try this.
void CMyButton::OnSize(...)
{
CButton::OnSize(...);
CRect rect(10,10,30,30);
m_rgn.DeleteObject();
SetWindowRgn(NULL, FALSE);
m_rgn.CreateEllipticRgnIndirect(rect);
SetWindowRgn(m_rgn, TRUE);
}
I hope this helps

Hi ,
HOW WHAT wrote: CRect rect;
GetClientRect(rect);
I'm not sure , but according to MSDN , GetClientRect()
gets as parameter the pointer to the rect , and not the rect
itself :
CWnd::GetClientRect
void GetClientRect( LPRECT lpRect ) const;
So try the following instead :
CRect rect;
GetClientRect(&rect);
Hopes this helps ,
Eli

CRect::operator LPRECT
CRect rect;GetClientRect(rect);
==
RECT rect;GetClientRect(&rect);
