Examples of org.xhtmlrenderer.layout.Layer

org.xhtmlrenderer.layout.Layer
All positioned content as well as content with an overflow value other than visible creates a layer. Layers which define stacking contexts provide the entry for rendering the box tree to an output device. The main purpose of this class is to provide an implementation of Appendix E of the spec, but it also provides additional utility services including page management and mapping boxes to coordinates (for e.g. links). When rendering to a paged output device, the layer is also responsible for laying out absolute content (which is layed out after its containing block has completed layout).

            // just draw background
            e.gc.fillRectangle(getClientArea());
        }


        // if this is the first time painting this document, then calc layout
        Layer root = getRootLayer();
        if (root == null || _needRelayout) {
            doLayout();
            root = getRootLayer();
            if (_offscreen != null) {
                // invalidate offscreen image
