Zen and SVGAttributeZen componentattributesDescription has the same general-purpose attributes as any Zen component. Fordescriptions, see these sections:• “Behavior” in the “Zen Component Concepts” chapter of Using Zen• “Component Style Attributes” in the “Zen Style” chapter of Using ZenbackgroundStyleSVG CSS style definition (Styles within SVG are CSS compliant, but there is a differentset of styles available.) Specifies the background style for the frame. This style mustinclude a fill value, or mouse events within this frame will not work correctly. The defaultbackgroundStyle is:"fill: white;"disableddragCanvaseditModeIf true, this frame and its children are disabled. The default is false.This attribute has the underlying data type %ZEN.Datatype.boolean. It has the value "true"or "false" in XData Contents, 1 or 0 in server-side code, true or false in client-side code.If true, the user can use the pointing device (mouse) to drag the canvas of this frame.This updates the values of the offsetX and offsetY attributes and moves the shapes onthe canvas. The default is false.This attribute has the underlying data type %ZEN.Datatype.boolean. It has the value "true"or "false" in XData Contents, 1 or 0 in server-side code, true or false in client-side code.Edit mode for this frame. Possible values are:• "none" — The user cannot edit the contents of this frame. This is the default.• "select" — The user can click on an SVG component to select it.• "drag" — The user can click on an SVG component, hold down the mouse button,and drag the SVG component to a new position.frameStyleCSS style definition that applies to this frame. For example, to produce the recessed,beveled border shown in the illustration above, you would use:frameStyle="border-style: inset;"gridXgridYIf snapToGrid is true, gridX defines the HTML width of each cell in the sizing grid. Thedefault is 25.If snapToGrid is true, gridY defines the HTML height of each cell in the sizing grid. Thedefault is 25.34 Using Zen Components
SVG Component LayoutAttributelayoutDescriptionSpecifies how the SVG components within this frame should be laid out. Possible valuesare:• "none" or the empty value "" — no layout is provided. When this is the case, componentsmay be placed using specific coordinates x and y. See the x and y attributesin the section “SVG Component Attributes.”• "vertical" — components within this group are laid out vertically.• "horizontal" — components within this group are laid out horizontally.• "flow" — components within this group are placed in rows. Items are placed horizontallyuntil the width of the container is exceeded, and then components are placedon the next row.offsetXoffsetYondragCanvasOffset, along the x-axis, of the coordinates of this frame from its upper, left-hand corner.The default is 0.Offset, along the y-axis, of the coordinates of this frame from its upper, left-hand corner.The default is 0.Client-side JavaScript expression that runs each time the user drags the backgroundcanvas using a pointing device. Generally this expression invokes a client-side JavaScriptmethod defined in the page class. A boolean variable, done, is passed to this eventhandler to indicate if the operation is complete.As with all event handler expressions including onmouseWheel, onmoveItem, etc:• When providing a value for this attribute, use double quotes to enclose the valueand single quotes (if needed) within the JavaScript expression. For example:• The JavaScript expression may contain Zen #()# runtime expressions.onmouseWheelonmoveItemonresizeItemonselectItemonzoomClient-side JavaScript expression that runs whenever the user moves the mouse wheelover the background rectangle of this frame. Currently only available in FireFox.Client-side JavaScript expression that runs whenever this frame is in drag mode andthe user moves one or more selected items. Refer to the selectedItems property for thelist of items. A boolean variable, done, is passed to this event handler to indicate if theoperation is complete.Client-side JavaScript expression that runs whenever this frame is in drag mode andthe user resizes one or more selected items. Refer to the selectedItems property for thelist of items. A boolean variable, done, is passed to this event handler to indicate if theoperation is complete.Client-side JavaScript expression that runs whenever the user changes the number ofselected items in this frame (by selecting or unselecting an item). A variable, item, ispassed to this event handler and refers to the item most recently selected or unselected.Client-side JavaScript expression that runs whenever the user changes the zoom levelfor this frame.Using Zen Components 35
