virtual bool VCF::XCBContextPeer::prepareForDrawing (  int32  drawingOperation  )  [virtual]
 

this method is called for the peer to initialize any graphics resources before calling the following methods:

  • textAt
  • getTextWidth
  • getTextHeight
  • rectangle
  • ellipse
  • arc
  • polyline
  • curve
  • moveTo
  • lineTo
Since the drawing primitives like (rectangle, moveTo, etc) are executed as a series of operations by the GraphicsContext, this means that prepareForDrawing() will get called as part of the GraphicsContext::fillPath(), GraphicsContext::strokePath(), or GraphicsContext::textAtXXX() methods. prepareForDrawing() will be called prior to any of the drawing primitive functions in the above list, allowing the peer to initialize whatever graphics resources need to be as specified by the GraphicsContext.

Currently the choices are 2: either it is aligned to the top, or in other words the coordinates specified represent the top, left position to start rendering the text, or aligned to the baseline, in which the top, left coordinates represent the baseline point of origin. The latter setting is useful when drawing text whith different font styles.
