我试图创建一个可编辑的标签,如示例 connection_labeledit_inplace 中的标签。
我遇到的问题是我想将标签附加到自定义 VectorFigure 以代替 Connection。这样做时,标签只是图形的一部分,不要启动编辑器。
ivr.shape.menu.MenuItem = graphiti.VectorFigure.extend({
NAME:"ivr.shape.menu.MenuItem",
MyOutputPortLocator : graphiti.layout.locator.Locator.extend({
init: function(parent)
{
this._super(parent);
},
relocate:function(index, figure){
var w = figure.getParent().getWidth();
var h = figure.getParent().getHeight();
figure.setPosition(w, h/2);
}
}),
/**
* @constructor
* Creates a new figure element which are not assigned to any canvas.
*
*/
init: function( width, height) {
this._super();
this.setBackgroundColor( new graphiti.util.Color(200,200,200));
this.setColor(new graphiti.util.Color(50,50,50));
// set some good defaults
//
if(typeof width === "undefined"){
this.setDimension(100, 15);
}
else{
this.setDimension(width, height);
}
// add port
var outputLocator = new this.MyOutputPortLocator(this);
this.createPort("output",outputLocator);
this.label = new graphiti.shape.basic.Label("I'm a Label");
this.label.setColor("#0d0d0d");
this.label.setFontColor("#0d0d0d");
this.addFigure(this.label, new graphiti.layout.locator.LeftLocator(this));
this.label.installEditor(new graphiti.ui.LabelInplaceEditor());
},
repaint : function(attributes)
{
if(this.repaintBlocked===true || this.shape===null){
return;
}
if (typeof attributes === "undefined") {
attributes = {};
}
var box = this.getBoundingBox();
var center = box.getCenter();
var path = ["M",box.x,",",box.y];
path.push("l", box.w-10, ",0");
path.push("l10,", box.h/2);
path.push("l-10,", box.h/2);
path.push("L",box.x,",", box.getBottomLeft().y);
path.push("Z");
var strPath = path.join("");
attributes.path = strPath;
this._super(attributes);
},
/**
* @method
* Called by the framework. Don't call them manually.
*
* @private
**/
createShapeElement:function()
{
// create dummy line
return this.canvas.paper.path("M0 0L1 1");
}
});
对于此示例,我将标签放在图形的左侧,但显然我会制作一个定位器,将标签放在图形上(以防万一它改变某些东西)
对我来说,问题来自“graphiti.Canvas.getBestFigure()”的工作方式。该函数仅检查直接附加到“graphity.Canvas”的元素此外,该函数缺少一些递归以将事件传播到子级。
