In Xceed's Extended Toolkit PropertyGrid, how do I hide the fully-qualified name of the expandable object? (see screenshot below)
you can override the ToString() method on your expandable object.
public override string ToString()
{
return this.FirstName + " " + this.LastName;
}

Here is what I exactly want to achieve but didn't have an answer. What's best practice to get the uid of CMSParagraphComponent on the storefront?
DefaultCMSComponentService
protected Collection<String> getEditorProperties(AbstractCMSComponentModel component, boolean readableOnly) {
String code = component.getItemtype();
if (!this.cEditorProperties.containsKey(code)) {
LOG.debug("caching editor properties for CMSComponent [" + component.getItemtype() + "]");
List<String> props = new ArrayList();
Collection<String> systemProps = this.getSystemProperties(component);
Set<AttributeDescriptorModel> attributeDescriptors = this.getTypeService()
.getAttributeDescriptorsForType(this.getTypeService().getComposedTypeForCode(code));
Iterator var8 = attributeDescriptors.iterator();
while (true) {
AttributeDescriptorModel ad;
String qualifier;
do {
do {
if (!var8.hasNext()) {
this.cEditorProperties.put(code, props);
return (Collection) this.cEditorProperties.get(code);
}
ad = (AttributeDescriptorModel) var8.next();
qualifier = ad.getQualifier();
} while (systemProps.contains(qualifier));
} while (readableOnly && !ad.getReadable());
props.add(qualifier);
}
} else {
return (Collection) this.cEditorProperties.get(code);
}
}
public Collection<String> getSystemProperties(AbstractCMSComponentModel component) {
String code = component.getTypeCode();
if (!this.cSystemProperties.containsKey(code)) {
LOG.debug("caching system properties for CMSComponent [" + component.getTypeCode() + "]");
List props = null;
try {
props = (List) Registry.getApplicationContext().getBean(code + "SystemProperties");
} catch (NoSuchBeanDefinitionException var5) {
LOG.debug("No bean found for : " + code + "SystemProperties", var5);
props = this.getSystemProperties();
}
this.cSystemProperties.put(code, props);
}
return (Collection) this.cSystemProperties.get(code);
}
It's not being populated because it's considered as the system property. Hence, as per the above logic system property will not be consider as redable property.
Now question is, How hybris get the list of system property for the given type? In another words, where this Registry.getApplicationContext().getBean(code + "SystemProperties") bean declare?
EDIT: The fact I know is, if Property attribute of AttributeDescriptor is set to false then it consider as system property. But when I checked for uid AttributeDescriptor, it (Property attribute) already set true.
There are some functionalities oob in hybris that uses the uid inside a view. For example the SearchPageController. To be more specific, let's take a look at this method :
private static final String COMPONENT_UID_PATH_VARIABLE_PATTERN = "{componentUid:.*}";
...
#ResponseBody
#RequestMapping(value = "/autocomplete/" + COMPONENT_UID_PATH_VARIABLE_PATTERN, method = RequestMethod.GET)
public AutocompleteResultData getAutocompleteSuggestions(...){
final SearchBoxComponentModel component = (SearchBoxComponentModel) cmsComponentService.getSimpleCMSComponent(componentUid);
}
The actual COMPONENT_UID_PATH_VARIABLE_PATTERN value is in the searchboxcomponent.jsp :
<spring:url value="/search/autocomplete/{/componentuid}" var="autocompleteUrl" htmlEscape="false">
<spring:param name="componentuid" value="${component.uid}"/>
</spring:url>
How does this work? Every time you type something, a call to this endpoint is made, with the component uid extracted using ${component.uid}.
Why does this work? Let's take a look at the productLayout1Page.jsp and take a simple tag from there:
<cms:pageSlot position="CrossSelling" var="comp" element="div" class="productDetailsPageSectionCrossSelling">
<cms:component component="${comp}" element="div" class="productDetailsPageSectionCrossSelling-component"/>
</cms:pageSlot>
Now we see that there is a <cms:component component=${..}.../> tag which reference a component instance and you can access it using ${component.attributeName} inside the component's jsp.
It seems not easy to get the uid on the storefront. But I have managed it like this
Create a dynamic attribute and return uid value from the getter method
Now you can populate this dynamic attribute on the frontend
I don't know how to describe it, so the question title may not make much sense.
Say, I have a class named User:
class User {
public String name;
public String getName(){
return this.name;
}
public String getName(long level){
// Calculate the name with level.
return name;
}
}
I know I could use ${user.name} in the template to invoke the getName() function, but what if I want to pass a level to invoke getName(long level) in template ?
Is there any alternative looks like ${user.name(123)}
Is it possible to make it ?
You just need
${user.getName(123)}
Consider a mixin class
class StringPlusMixin {
String plus(String other) {
return toString() + other
}
}
And his use case
#Mixin(StringPlusMixin)
class POGO {
String descr
String toString(){
return descr
}
}
Is there some way to make SringPlusMixin to use POGO#toString() instead of SringPlusMixin#toString() ?
The actual output is:
POGO pogo = new POGO(descr: "POGO description");
System.out.println(pogo + "Some message."); //StringPlusMixin#f410f8 Some message.
I'm considering to use this mixin since the Groovy default of instance + String is to try to call a plus() method. I'm using my POGO in several Java classes and trying to not need to change all messages to use toString().
Use #Delegate transformation in POGO.
#Mixin(StringPlusMixin)
class POGO {
#Delegate String descr
String toString(){
return descr
}
}
Since descr is owned by POGO, in runtime use of descr is delgated to the owner which is POGO.
Reflection? Also, i turned your class into a Category, by making the method static and passing the child object as first parameter.
Update: as per comments, removed the type from the mixin method
import org.codehaus.groovy.runtime.InvokerHelper as Invoker
class StringPlusMixin {
static String plus(pogo, String other) {
def toString = pogo.class.declaredMethods.find { it.name == "toString" }
return toString.invoke(pogo) + other
}
}
#Mixin(StringPlusMixin)
class POGO {
String descr
String toString(){
return descr
}
}
pogo = new POGO(descr: "POGO description")
assert pogo + " Some message." == "POGO description Some message."
Is there a way to store an identifier of a model object or the model object itself in a JavaFX 2 TreeItem<String>? There is just Value to store the text...
I'm populating a TreeView from a list of model objects, and need to find it when the user clicks a node. I'm used to work with Value and Text in .NET Windows Forms or HTML and I am afraid I cannot adapt this way of thinking to JavaFX...
You can use any objects with TreeView, they just have to override toString() for presenting or extend javafx.scene.Node
E.g. for next class:
private static class MyObject {
private final String value;
public MyObject(String st) { value = st; }
public String toString() { return "MyObject{" + "value=" + value + '}'; }
}
TreeView should be created next way:
TreeView<MyObject> treeView = new TreeView<MyObject>();
TreeItem<MyObject> treeRoot = new TreeItem<MyObject>(new MyObject("Root node"));
treeView.setRoot(treeRoot);
I have the same issue as the OP. In addition I want to bind the value displayed in the TreeItem to a property of the object. This isn't complete, but I'm experimenting with the following helper class, where I'm passing in the "user object" (or item) to be referenced in the TreeItem, and a valueProperty (which, in my case, is a property of the item) to be bound to the TreeItem.value.
final class BoundTreeItem<B, T> extends TreeItem<T> {
public BoundTreeItem(B item, Property<T> valueProperty) {
this(item, valueProperty, null);
}
public BoundTreeItem(B item, Property<T> valueProperty, Node graphic) {
super(null, graphic);
itemProperty.set(item);
this.valueProperty().bindBidirectional(valueProperty);
}
public ObjectProperty<B> itemProperty() {
return itemProperty;
}
public B getItem() {
return itemProperty.get();
}
private ObjectProperty<B> itemProperty = new SimpleObjectProperty<>();
}
I'm not sure about one thing. There are two things in object oriented programming.
Constructor
Method
Which one of these can be overloaded and which one overridden?
Thanks!
both can be overloaded.
overloading means having two or more methods or constructors with exactly same name but different signatures. some thing like :
public myClass(String a){}
public myClass(Double d){}
or for methods :
public void aMethod(String s){}
publis int aMethod(Double d){
return 0;
}
edited :
bebin, overriding usually comes with inheritance , when the super class implements a method but the subclass needs to implement that method in other way like :
in super class:
public int doSomething(){
return a+2;
}
but in subclass :
#override
public in doSomething(){
return a*2;
}
and about constructor overriding the following line are from CollinD and i am quoting it :
"Constructors are not normal methods and they cannot be "overridden". Saying that a constructor can be overridden would imply that a superclass constructor would be visible and could be called to create an instance of a subclass. This isn't true... a subclass doesn't have any constructors by default (except a no-arg constructor if the class it extends has one). It has to explicitly declare any other constructors, and those constructors belong to it and not to its superclass, even if they take the same parameters that the superclass constructors take.
The stuff you mention about default no arg constructors is just an aspect of how constructors work and has nothing to do with overriding."
That may depend on the language, but theoretically both can be both overloaded and overridden.
C# examples of everything:
class Parent {
protected string Name;
public Parent(string name) {
this.Name = name;
}
public Parent(string firstName, string lastName) {
this.Name = firstName + " " + lastName;
}
public virtual string GetName() {
return this.Name;
}
}
class Child : Parent {
public Child(string firstName) : base(firstName, "Doe") {}
public override string GetName() {
return this.Name = " Jr.";
}
public string GetName(string prefix) {
return prefix + " " + this.GetName();
}
}
This illustrates constructor and method overriding and constructor and method overloading.
You can overload and override both constructors and methods. (I think constructors are really just a special kind of method.)
Overriding allows a subclass to replace the implementation of its parent class.
Overloading allows you to create a different versions of a method that take different parameter lists.
