#画矩形 DrawRectangle(x,y,width,height) 左上角是（x,y）,其宽和高是width和 height
#画椭圆 DrawEllipse
画图标： DrawIcon(icon,x,y)
#画线： DrawLine(x1,y1,x2,y2)
#画连接线 DrawLines（）该方法以wx.Point对象的一个Python列表为参数，并将其中的点连接起来
#画多边形 DrawPolygon(points) 按给定的wx.Point对象的一个Python列表回执一个多边形
#画字符串DrawText(text,x,y) 从（x,y）开始绘制给定的字符串，使用当前的字体。相关的函数包括D让我RotateDText()和GetTextExtent().
#区域填充 FloodFill(x, y, color,style)：从点(x, y)执行一个区域填充，使用当前画刷的颜色。参数style是可选的。style的默认值是wx.FLOOD_SURFACE，它表示当填充碰到另一颜色时停止。另一值wx.FLOOD_BORDER表示参数color是填充的边界，当填充碰到该颜色的代表的边界时停止。
GetBackground() SetBackground(brush)：背景画刷是一个wx.Brush对象，当Clear()方法被调用时使用。
GetBrush() SetBrush(brush)：画刷是一个wx.Brush对象并且用于填充任何绘制在设备上下文上的形状。
GetFont() SetFont(font)：字体(font)是一个wx.Font对象，被用于所有的文本绘制操作。
GetPen() SetPen(pen)：画笔(pen)是一个wx.Pen对象，被用于所有绘制线条的操作。
GetPixel(x, y)：返回一个关于点(x, y)的像素的一个wx.Colour对象。
GetSize()
GetSizeTuple()：以一个wx.Size对象或一个Python元组的形式返回设备上下文的像素尺寸。
