/**
|
|
This class implements an inspector for GoJS model data objects.
|
|
The constructor takes three arguments:
|
|
{string} divid a string referencing the HTML ID of the to-be inspector's div.
|
|
{Diagram} diagram a reference to a GoJS Diagram.
|
|
{Object} options An optional JS Object describing options for the inspector.
|
|
|
|
Options:
|
|
inspectSelection {boolean} Default true, whether to automatically show and populate the Inspector
|
|
with the currently selected Diagram Part. If set to false, the inspector won't show anything
|
|
until you call Inspector.inspectObject(object) with a Part or JavaScript object as the argument.
|
|
includesOwnProperties {boolean} Default true, whether to list all properties currently on the inspected data object.
|
|
properties {Object} An object of string:Object pairs representing propertyName:propertyOptions.
|
|
Can be used to include or exclude additional properties.
|
|
propertyModified function(propertyName, newValue) a callback
|
|
multipleSelection {boolean} Default false, whether to allow multiple selection and change the properties of all the selected instead of
|
|
the single first object
|
|
showAllProperties {boolean} Default false, whether properties that are shown with multipleSelection use the intersect of the properties when false or the union when true
|
|
only affects if multipleSelection is true
|
|
showSize {number} Defaults 0, shows how many nodes are showed when selecting multiple nodes
|
|
when its lower than 1, it shows all nodes
|
|
|
|
Options for properties:
|
|
show: {boolean|function} a boolean value to show or hide the property from the inspector, or a predicate function to show conditionally.
|
|
readOnly: {boolean|function} whether or not the property is read-only
|
|
type: {string} a string describing the data type. Supported values: "string|number|boolean|color|arrayofnumber|point|rect|size|spot|margin|select"
|
|
defaultValue: {*} a default value for the property. Defaults to the empty string.
|
|
choices: {Array|function} when type == "select", the Array of choices to use or a function that returns the Array of choices.
|
|
|
|
Example usage of Inspector:
|
|
|
|
var inspector = new Inspector("myInspector", myDiagram,
|
|
{
|
|
includesOwnProperties: false,
|
|
properties: {
|
|
"key": { show: Inspector.showIfPresent, readOnly: true },
|
|
"comments": { show: Inspector.showIfNode },
|
|
"LinkComments": { show: Inspector.showIfLink },
|
|
"chosen": { show: Inspector.showIfNode, type: "checkbox" },
|
|
"state": { show: Inspector.showIfNode, type: "select", choices: ["Stopped", "Parked", "Moving"] }
|
|
}
|
|
});
|
|
|
|
This is the basic HTML Structure that the Inspector creates within the given DIV element:
|
|
|
|
<div id="divid" class="inspector">
|
|
<tr>
|
|
<td>propertyName</td>
|
|
<td><input value=propertyValue /></td>
|
|
</tr>
|
|
...
|
|
</div>
|
|
|
|
