C++ (Cpp) _Draw_Image Examples

Example #1

File: view_scatterplot.cpp Project: johanvdw/SAGA-GIS-git-mirror

//---------------------------------------------------------
void CVIEW_ScatterPlot::_Draw(wxDC &dc, wxRect r)
{
	r	= _Draw_Get_rDiagram(r);

	if( m_Trend.Get_Data_Count() > 1 )
	{
		//-------------------------------------------------
		if( m_Options("DISPLAY")->asInt() == 1 )
		{
			if( m_Options("DENSITY_LEG")->asBool() )
			{
				r.SetRight(r.GetRight() - 40);

				_Draw_Legend(dc, wxRect(r.GetRight() + 10, r.GetTop(), 40 - 20, r.GetHeight()));
			}

			_Draw_Image (dc, r);
		}
		else
		{
			_Draw_Points(dc, r);
		}

		//-------------------------------------------------
		_Draw_Frame(dc, r);
	}
	else
	{
		Draw_Text(dc, TEXTALIGN_CENTER, r.GetLeft() + r.GetWidth() / 2, r.GetTop() + r.GetHeight() / 2, _TL("Invalid data!"));
	}
}
