BOOL CScrollerCorner::Create (  LPCTSTR  , LPCTSTR  , DWORD  style, const wxRect &  rect, wxWindow *  pParent, UINT32  id )  [virtual]

Creates (attaches) the Windows interface element which corresponds to the C++ CScrollerCorner object. The CScrollerCorner's background brush is set to the one used to colour scroll bars. Author: Justin_Flude (Xara Group Ltd) <camelotdev@xara.com> Date: ages ago Parameters: Two  dummy long pointers to constant TCHARs, the window-instance flags, a [INPUTS] rectangle describing the position of the "corner", a pointer to the parent window, the numeric child window identifier, a pointer to a creation context. -  [OUTPUTS] Returns: TRUE if the window is successfully created. Errors: - Scope: Public See also: CCamView::OnCreate() Definition at line 180 of file scroller.cpp. { return wxWindow::Create( pParent, id, rect.GetTopLeft(), rect.GetSize(), style ); /* return CWnd::Create(AfxRegisterWndClass( CS_HREDRAW | CS_VREDRAW | CS_DBLCLKS, 0, HBRUSH(COLOR_SCROLLBAR + 1), 0), "", style | WS_CHILD | WS_CLIPSIBLINGS | WS_VISIBLE, rect, parent, id, ctxt); */ }

void CScrollerCorner::OnLButtonDown (  wxMouseEvent &  event  )

Send a fake non-client msg to our parent to allow sizing via this window. Author: Justin_Flude (Xara Group Ltd) <camelotdev@xara.com> Date: 5/10/95 Definition at line 295 of file scroller.cpp. { #ifdef GERRYXXX CWnd::OnLButtonDown(nFlags, pt); CWnd* pParent = GetParent(); CRect rWin; pParent->GetWindowRect(&rWin); // calc screen coords of bottom-right frame corner pt.x = rWin.Width() - 1; pt.y = rWin.Height() - 1; pParent->ClientToScreen(&pt); pParent->SendMessage(WM_NCLBUTTONDOWN, WPARAM(HTSIZE), MAKELPARAM(WORD(pt.x), WORD(pt.y))); #endif }

void CScrollerCorner::OnPaint (  wxPaintEvent &  event  )

Paints the client area of the CScrollerCorner. Scope: Protected. Author: Chris_Snook (Xara Group Ltd) <camelotdev@xara.com> Date: 8/10/95 See also: CScrollerCorner::Create() Definition at line 215 of file scroller.cpp. { #ifdef GERRYXXX CPaintDC dc(this); // Draw the resizing gadget. CPen nullpen(PS_NULL, 0, RGB(0, 0, 0)); CPen* oldpen = dc.SelectObject(&nullpen); dc.SetROP2(R2_COPYPEN); // Create an appropriately coloured brush to fill the scroller's background. CBrush brush(::GetSysColor(COLOR_BTNFACE)); CBrush* oldbrush = dc.SelectObject(&brush); // Draw the body of the scroller corner. CRect rClient; GetClientRect(&rClient); dc.Rectangle(&rClient); // Draw the size gadget on top if not maximised. BOOL fIsMaxed; GetMainFrame()->MDIGetActive(&fIsMaxed); if (!fIsMaxed) { CDC scrDC; scrDC.CreateCompatibleDC(&dc); CBitmap* pOldSrcBitmap = (CBitmap*) scrDC.SelectObject(&SizeBitmap); dc.BitBlt(0, 0, rClient.Width(), rClient.Height(), &scrDC, 0, 0, SRCCOPY); scrDC.SelectObject(pOldSrcBitmap); } // Deselect the drawing tools before destroying the DC. dc.SelectObject(oldbrush); dc.SelectObject(oldpen); #endif }

void CScrollerCorner::OnSetCursor (  wxSetCursorEvent &  event  )

Fakes the sizing gadget for our custom scrollbars. Author: Justin_Flude (Xara Group Ltd) <camelotdev@xara.com> Date: 14 Oct 93 Parameters: event  The standard SetCursor event, which contains all the info to handle [INPUTS] the request -  [OUTPUTS] Returns: TRUE, ie. the cursor has been set, and no further processing is necessary.
