Hi, I am working on a graphics editor using Batik and am designing property sheets for SVG elements and would like some feedback on the design. Any and all comments are welcome.
1) Each property sheet will extend org.apache.batik.ext.swing.JGridBagPanel. Property sheets may fall into any of these categories - Presentation Attributes JSVGFillStrokePanel (fill, stroke, stroke-width, fill-opacity, etc.), JSVGFontPanel (font-family, font-size, etc.) JSVGGradientsPanel (stop-color and stop-opacity) JSVGTextContentPanel (alignment-baseline, baseline-shift, direction, etc.) - Standard Attributes JSVGStandardPanel (id and xml:base) - Element-Specific Attributes JSVGRectPanel (x, y, rx, ry, width, and height) JSVGEllipsePanel (cx, cy, rx, and ry) and so on... 2) A subclass of JDialog (JSVGAttributeDialog) will aid in the composition of these property sheets into a JTabbedPane (or similar). This will be done by inspecting the SVGElement instance for implemented interfaces. This dialog may have a show() method that takes an SVGElement as a parameter as follows: JSVGAttributeDialog dialog = new JSVGAttributeDialog(owner); SVGSVGElement elem = doc.getRootElement(); dialog.show(elem); If the user clicks the "Ok" button, the SVGElement's attributes are modified. 3) A registration mechanism will be provided for developers to use their own property sheets for certain attribute classes when they see fit. This mechanism could also be used if the developer wants only a subset of the property sheets displayed. This mechanism would also allow for pooling of the property panel instances. 4) Attribute values which may contain references to other elements within the document may be selected in a combo box (or similar). 5) These property sheets will be demonstrated in a modification to the SVG Browser DOM viewer. How useful does this seem to others? If others would find this useful and have insight, I'd love to hear it. Also, I am completely willing to contribute this code to the Batik community. Thanks.
