CDC::DrawFrameControl
Call this member function to draw a frame control of the specified type and style.
BOOL DrawFrameControl(
LPRECT lpRect,
UINT nType,
UINT nState
);
Parameters
lpRect
A pointer to a RECT structure that contains the logical coordinates of the rectangle.nType
Specifies the type of frame control to draw. See the uType parameter in DrawFrameControl in the Windows SDK for a list of this parameter's possible values.nState
Specifies the initial state of the frame control. Can be one or more of the values described for the uState parameter in DrawFrameControl in the Windows SDK. Use the nState value DFCS_ADJUSTRECT to adjust the bounding rectangle to exclude the surrounding edge of the push button.
Return Value
Nonzero if successful; otherwise 0.
Remarks
In several cases, nState depends on the nType parameter. The following list shows the relationship between the four nType values and nState:
DFC_BUTTON
DFCS_BUTTON3STATE Three-state button
DFCS_BUTTONCHECK Check box
DFCS_BUTTONPUSH Push button
DFCS_BUTTONRADIO Radio button
DFCS_BUTTONRADIOIMAGE Image for radio button (nonsquare needs image)
DFCS_BUTTONRADIOMASK Mask for radio button (nonsquare needs mask)
DFC_CAPTION
DFCS_CAPTIONCLOSE Close button
DFCS_CAPTIONHELP Help button
DFCS_CAPTIONMAX Maximize button
DFCS_CAPTIONMIN Minimize button
DFCS_CAPTIONRESTORE Restore button
DFC_MENU
DFCS_MENUARROW Submenu arrow
DFCS_MENUBULLET Bullet
DFCS_MENUCHECK Check mark
DFC_SCROLL
DFCS_SCROLLCOMBOBOX Combo box scroll bar
DFCS_SCROLLDOWN Down arrow of scroll bar
DFCS_SCROLLLEFT Left arrow of scroll bar
DFCS_SCROLLRIGHT Right arrow of scroll bar
DFCS_SCROLLSIZEGRIP Size grip in bottom-right corner of window
DFCS_SCROLLUP Up arrow of scroll bar
Example
This code draws the size gripper in the bottom-right corner of your window. It's appropriate for the OnPaint handler of a dialog box, which has no styles and normally doesn't contain other controls (like a status bar) that may give it a size gripper.
void CDCView::DrawFC(CDC* pDC)
{
CRect rc;
GetClientRect(&rc);
rc.left = rc.right - ::GetSystemMetrics(SM_CXHSCROLL);
rc.top = rc.bottom - ::GetSystemMetrics(SM_CYVSCROLL);
pDC->DrawFrameControl(rc, DFC_SCROLL, DFCS_SCROLLSIZEGRIP);
}
