screen flickering Topic is solved

[zhouhao]

I'm tring to mix the components with the wxWidgets drawing in a wxPanel. Here is part of my code:

Code: Select all

//////////////////////////////////////////////////
//  inside my panel's constructor
	wxString wxRadioBoxChoices_RadioBox1[2];
	wxRadioBoxChoices_RadioBox1[0] = _("Option 1");
	wxRadioBoxChoices_RadioBox1[1] = _("Option 2");
	RadioBox1 = new wxRadioBox(this,ID_RADIOBOX1,_T(""),wxPoint(0,77),wxSize(124,109),2,wxRadioBoxChoices_RadioBox1,1,0);

    m_bmpSprite.LoadFile(_T("sprites.png"),wxBITMAP_TYPE_PNG);

//////////////////////////////////////////////////////
// inside my onPaint event
	wxBufferedPaintDC dc(this);
	wxASSERT(TRUE == dc.Ok());

    dc.SetBackground(*wxWHITE_BRUSH);
    dc.Clear();
    dc.DrawBitmap(m_bmpSprite, m_iX+i, 0+i*20, true);


////////////////////////////////////////////////////////
// inside my onTimer event which is trigger every 50ms
	int w,h;
	GetClientSize(&w,&h);

    if ( m_iX < w && m_iX >= 100 )
        m_iX += 1;
    else
        m_iX = 100;

   Refresh();

My animation is working fine. But the problem is the Radiobox is always flickering. Can anybody help?

Add this before you create rhe radio box

Code: Select all

wxSystemOptions::SetOption(_T("msw.staticbox.optimized-paint"), 0);

Thanks for your reply. But the effect is that the background of the radiobox becomes transparent and the flickers still exist.

do you draw your sprite over your radiobutton? If not, try using wxWindow::RefreshRect and refresh only the area where your sprite moves

That's cool. It works. Thank you.
