如何将自定义节点和属性添加到AlloyUI图表生成器 [英] How to add custom nodes and properties to AlloyUI diagram builder

问题描述

我一直在尝试使用AlloyUI的图表生成器示例.

I have been trying to use diagram builder example of AlloyUI.

我需要为节点添加一些额外的自定义节点类型以及一些其他属性.我曾考虑过修改然后构建库，但这听起来像是对这项任务的过大杀伤力，而且我还问题与建筑物.

I need to add some extra custom node types as well as some additional properties for the nodes. I thought about modifying and then building the library but it sounds like an overkill for such a task and also I have had issues with building.

有一种简单的方法吗?

更新

我意识到我可以直接修改构建文件夹中的文件以摆脱构建过程.我尝试添加类似的内容:

I realized I could directly modify files in build folder to get rid of build process. I tried adding something like:

var Lang = A.Lang,
..
CUSTOM = 'custom',
..

..
A.DiagramNodeCustom = A.Component.create({
  NAME: DIAGRAM_NODE_NAME,

  ATTRS: {
    type: {
      value: CUSTOM
    },
  },

  EXTENDS: A.DiagramNodeTask
});

A.DiagramBuilder.types[CUSTOM] = A.DiagramNodeCustom;

到/build/aui-diagram-builder-impl/aui-diagram-builder-impl.js.

我的主要javascript文件结构如下:

I have my main javascript file structures as such:

var Y = YUI().use(
  'aui-diagram-builder',
  ..
  function(Y) {
    var availableFields = [
      ..
      {
        iconClass: 'aui-diagram-node-task-icon',
        label: 'Custom',
        type: 'custom'
      },
      ..
    ];

    diagram = new Y.DiagramBuilder(
      {
        availableFields: availableFields,
        boundingBox: '#myDiagramContainer',
        srcNode: '#myDiagramBuilder'
      }
    ).render();
    ..
  }
);

，我知道将自定义节点添加到图表中.我可以单击它并更改名称，但是不幸的是，它在图中是不可见的.而且我仍然找不到如何向节点添加新属性.有什么想法吗?

and I can know add a custom node to my diagram. I can click on it and change the name and such but unfortunately it is invisible on the diagram. Also I still couldn't find how to add new attributes to nodes. Any ideas?

推荐答案

如上所述，您到目前为止所做的一切听起来都不错.

As stated, everything you did so far sounds good.

我认为您只是缺少一些CSS才能看到您的节点.您可以在此处

I think you're only missing some CSS to be able to see your nodes. You can see it working here

查看CSS面板

.aui-diagram-node-custom .aui-diagram-node-content {
   /* Style of your node in the diagram */
}

.aui-diagram-node-custom-icon {
   /* Style of your node icon in the nodes lists */
}

注意:从Alloy-2.0.0pr6开始，css类不再以 aui-作为前缀，因此在开始使用较新版本时，请记住这一点.我在此处

Note: Starting from alloy-2.0.0pr6, css classes are no longer prefixed with aui-, so keep that in mind when you start using a newer version. I've put together an example here

编辑:为了能够向编辑器面板公开新属性，自定义字段需要扩展getPropertyModel方法，以将新属性添加到模型中.

To be able to expose new attributes to the editor panel, the custom field needs to extend the getPropertyModel method to add the new properties to the model.

getPropertyModel: function() {
    var instance = this;

    var model = Y.DiagramNodeTask.superclass.getPropertyModel.apply(instance, arguments);

    model.push({
        attributeName: 'customAttr',
        name: 'Custom Attribute'
    });

    return model;
}

在这里您可以找到更新的示例
