CHTMLView and Flicker
in [MFC]
|
From: AliR on 8 Feb 2006 16:00 Hi All, Has anyone come up with a good way to eliminate the flicker when you resize a CHTMLView? AliR.
From: Ajay Kalra on 8 Feb 2006 16:06 Did you try removing CS_HREDRAW/CS_VREDRAW from its parent window class. That should do it. -------- Ajay Kalra ajaykalra(a)yahoo.com
From: AliR on 8 Feb 2006 16:30 Hey Ajay, I think this is what you ment: BOOL CChildFrame::PreCreateWindow(CREATESTRUCT& cs) { cs.style &= ~(CS_HREDRAW|CS_VREDRAW); if( !CMDIChildWnd::PreCreateWindow(cs) ) return FALSE; return TRUE; } It didn't help.

From: "TerryFei" on 8 Feb 2006 22:50 Hi AliR, Welcome to MSDN Newsgroup! In the current situation, please help me to confirm some information on your side: is your project type MDI? Based on my knowledge, you could try to use the following ways to solve flick issue: 1. Override PreCreateWindow method, just like: BOOL CChildFrame::PreCreateWindow(CREATESTRUCT& cs) { // TODO: Modify the Window class or styles here by modifying // the CREATESTRUCT cs cs.style = WS_CHILD | WS_OVERLAPPED | WS_CAPTION | WS_SYSMENU | FWS_ADDTOTITLE | WS_THICKFRAME | WS_MINIMIZEBOX | WS_MAXIMIZEBOX | WS_MAXIMIZE; //set the window style to Maximize, but don't show it as first cs.cx = 1024; cs.cy = 768; // Set windows's size to full screen's size if( !CMDIChildWndEx::PreCreateWindow(cs) ) return FALSE; cs.style |= WS_VISIBLE; //Show windows only afer finish return TRUE; } 2??In order to update window,redraw operation occurs at frequently. If redraw operation is not so fast, flick will happen. So if we forbid window's redraw operation properly and restore to redraw at proper time, it could solve the flick issue.We could handle WM_WINDOWPOSCHANGING and WM_WINDOWPOSCHANGED to achieve this goal. I hope the above information is helpful for you. If you have any questions or concerns, please let me know. Thanks for your understanding and have a nice day!

It's an MDI application. Try for yourself: Create an MDI application using the Wizard, change the view from CView to CHTMLView. Build and run project, resize the view and notice the flicker. I have tried a couple of solutions I found on CodeProject, but none make the flicker go away. AliR.
