C++ (Cpp) wxRegion::GetBox Examples

Example #1

File: macutils_cocoa.cpp Project: dongmingdmdm/OpenCPN

// workaround for 2.9 cocoa where the equality operator for region is currently (2011-03-09) not implemented
bool ocpn_mac_region_compare(const wxRegion& r1, const wxRegion& r2)
{
	wxCoord x1,x2,y1,y2,w1,w2,h1,h2;
	r1.GetBox(x1,y1,w1,h1);
	r2.GetBox(x2,y2,w2,h2);
	if(x1 == x2 && y1 == y2 && w1 == w2 && h1 && h2) return true;
	return false;
}

Example #2

File: gcImageControl.cpp Project: callumlinden/desura-app

//for some f****d up reason getright and get bottom return one less than needed. Fixed in newer wxWidgets :(
wxBitmap ConvertRegionToBitmap(const wxRegion& r)
{
    wxRect box = r.GetBox();
    wxBitmap bmp(box.GetRight()+1, box.GetBottom()+1);
    wxMemoryDC dc;
    dc.SelectObject(bmp);
    dc.SetBackground(*wxBLACK_BRUSH);
    dc.Clear();
    dc.SetDeviceClippingRegion(*static_cast<const wxRegion *>(&r));
    dc.SetBackground(*wxWHITE_BRUSH);
    dc.Clear();
    dc.SelectObject(wxNullBitmap);
    return bmp;
