Need to find way to add hyperlinks to components of an assembly in the a360 viewer such that, when clicked or touched with mobile device, will navigate to a web page for more information. Realize it requires Forge API but can't find any specific examples of such a solution. I think this can be done from a properties table but I want direct navigation from touching/clicking the object.
You could just subscribe to the object selection event and react to it by e.g. opening a given URL:
viewer.addEventListener(
Autodesk.Viewing.SELECTION_CHANGED_EVENT,
function (event) {
// Get id of first selected item
var dbId = event.dbIdArray[0];
if (dbId) {
// Maybe get the properties of the selected object
viewer.getProperties(dbId, function (props) {
// Depending on the properties you could open a website
// Just printing to the console the external id of
// the selected component as an example
console.log(props.externalId);
});
}
}
);
If you search for "Autodesk.Viewing.SELECTION_CHANGED_EVENT" you can find some articles and samples also using this event, e.g. https://forge.autodesk.com/blog/selection-override

We've created solution where user has a table with files, each entry has checkbox. He can select as many as he like and then click download button.
We are using such resource, it should allow dynamically download, depending on selected items
private StreamResource createResource(final IndexedContainer container) {
return new StreamResource(new StreamSource() {
#Override
public InputStream getStream() {
for (Object o : container.getItemIds()) {
CheckBox checkbox = (CheckBox) container.getItem(o).getItemProperty(C_CHECK_BOX).getValue();
if (checkbox.getValue()) {
selectedFiles.add(o);
}
}
// do some magic to get stream of selected files
}
}, "download.zip");
}
The problem is that only second and following click on button is giving expected restults.
It's turns out that FileDownoader is getting resource from server and then it is sending current status of component . It is the reason why first click is giving stale result.
Do you have any idea how to overcome this? Is it possible to force: first update component and then download the resource?
Many thanks

CheckBox in Vaadin is non-immediate by default, which means that it won't send a request to server when the checkbox is checked (or unchecked) on the browser. Immediate components send queued non-immediate events also to server but it seems that FileDownloader doesn't cause an event that would send non-immediate checkbox values to server.
The only thing you need to do is to set your checkboxes to be immediate when you create those:
checkBox.setImmediate(true);
FileDownloader will not suit your needs. As you can read in the documentation:
Download should be started directly when the user clicks e.g. a Button without going through a server-side click listener to avoid triggering security warnings in some browsers.
That means you cannot dynamically generate download.zip file determined by checkboxes values because that requires a trip to server.
You have at least 2 options. Either create new FileDownloader and generate new Resource download.zip every time user make changes to the checkboxes. Or you can add simple ClickListener to you Button with this line of code:
getUI().getPage().open(resource, "_blank", false);

There is also alternative solution to set checkBox.setImmediate(true); . It is possible to send current state of all components, just before click, instead of sending each checkBox change.
This solution is based on this answer: https://stackoverflow.com/a/30643199/1344546
You need to create file downloader button and hide it:
Button hiddenButton = new Button();
hiddenButton.setId(HIDDEN_ID);
hiddenButton.addStyleName("InvisibleButton");
StreamResource zipResource = createResource(container);
FileDownloader fd = new FileDownloader(zipResource);
fd.extend(hiddenButton);
Add css rule to your theme
.InvisibleButton {
display: none;
}
And then create another button, which 1st update state, and then click hidden button.
Button zipDownload = new Button("Download as ZIP file");
zipDownload.addClickListener(new Button.ClickListener() {
#Override
public void buttonClick(Button.ClickEvent event) {
Page.getCurrent().getJavaScript()
.execute(String.format("document.getElementById('%s').click();", HIDDEN_ID));
}
});
I am extending hcm.emp.payslip app and need to add a button in the footer....what is the right way of doing it?..
option 1: placing a extension point as described in page 13 of this pdf.. -- it didnt work..I followed exactly the steps mentioned. or will this not work as we are inserting an extension point ourselfs and which is not supported now.?
option 2: extending UI controller hooks as described here -- I couldnt try this as the documentation is very brief and I am a beginner...Also I am not sure if we can change the view by extending controller
I am using eclipse, and installed the Tool kit plug-in, some places I saw they recommended using Web IDE, but we would like to do it using tool kit, as I am not sure if we have cloud HANA access. or is it still fine to use the UI tool kit way..
would like to suggest the right approach with detailed steps...
Your Option 1 is not possible(Why? Because to add button to the footer there is controllerHook not UI extension point)
Go with Option 2 there are already extensionHooks given in all the controllers (S3.controller.js and in S3_phone.controller.js) of detail pages of the application.
controllerHook : extHookChangeFooterButtons
by Default SAP builds headerFooterOptions and sends that object to your extension Hook
/**
* #ControllerHook Modify the footer buttons
* This hook method can be used to add and change buttons for the detail view footer
* It is called when the decision options for the detail item are fetched successfully
* #callback hcm.emp.payslip.view.S3_Phone~extHookChangeFooterButtons
* #param {object} objHdrFtr-Header Footer Object
* #return {object} objHdrFtr-Header Footer Object
*/
if (this.extHookChangeFooterButtons) {
objHdrFtr = this.extHookChangeFooterButtons(objHdrFtr);
}
So you in the extended controller, receive the same append:
extHookChangeFooterButtons: function (objHdrFtr) {
//first if the buttonsList is empty, create one.
//Actually in S3.controller.js buttonsList is not defined since there are no buttons
if (!objHdrFtr.buttonList) {
objHdrFtr.buttonList = [];
}
//then create a button:
var extendedButton = {
sId: "EXT_BUTTON",
sI18nBtnTxt: "SAMPLE", //make sure you add texts in respective i18n files
bEnabled: true,
onBtnPressed: function (evt) {
that.handleExtButtonPress(evt);
}
};
objHdrFtr.buttonList.append(extendedButton)
//as you can see SAP says to return the object
return objHdrFtr;
}
Suggestion: Its very easy to do it in Web IDE.
Why?
It takes no time SETUP.
Very easy to use, saves lot of time
Shows all controllerHooks,
extension Points in UI
For the above example in Fiori Inbox use B.aButtonList.push(extendedButton); which will add the button to the end of the list (instead of append)
I am very new to ZK framework and trying to customize few things and have struck at one point which I am not sure how to achieve that.
I have a predefined section where I need to show 2 drop down and a button and need to persist those drop down values on button click event.
This is how It has been define in Spring file
<bean id="mybean" parent="parentBean" class="WidgetRenderer">
<property name="detailRenderer">
<bean class="DetailsListRenderer" parent="abstractWidgetDetailRenderer"/>
</property>
</bean>
Here mybean is being used to show main section and I am adding my drop down using this bean while button are being added to detailRenderer.
Save button is bind to onClick event, but I am not sure how I can fetch values from my custom drop down?
I am aware about binding those Dropdown with onClick event but they have to be in same class.
Can any one suggest me how I can fetch values of those drop down.I am creating down down with following code
Listbox listbox = new Listbox();
listbox.appendItem("item1", "item1");
listbox.appendItem("item2", "item2");
This is my button code in another class
protected void createUpdateStatusButton(Widget widget,Div container)
{
Button button = new Button(LabelUtils.getLabel(widget, buttonLabelName, new Object[0]));
button.setParent(container);
button.addEventListener("onClick", new EventListener()
{
public void onEvent(Event event)throws Exception
{
MyClass.this.handleSaveStatusEvent(widget, event);
}
});
}
You may want to listen to the onSelect (I prefer to use Events.ON_SELECT rather than writing the strings) which is more specific to when the Listbox selection changes.
Either way, the key is to get the information you want from the Event passed to your EventListener, rather than going back to your Listbox itself. The basic Event usually carries useful information on getTarget and getData but using more specific events (SelectEvent in this case) will give you access to more relevant info.
button.addEventListener(Events.ON_SELECT, new EventListener<SelectEvent<Listitem, MyDataObject>() {
public void onEvent(SelectEvent<Listitem, MyDataObject> event) {
// Now you can access the details of the selection event..
List<Listitem> selectedItems = event.getSelectedItems();
List<MyDataObject> selectedObjects = event.getSelectedObjects();
}
});
You can find out what events are available for different ZK widgets in their Component Reference documentation.
If I understand the question (I don't think I did in my previous response) you want to gather information from the page (eg: Listbox selection state) when the user clicks a button. Your problem being that you are using disparate classes to compose the page and so don't have access to the various ZK Components when the button is clicked.
(Ignoring the multiple class issue for a minute)
From a high level, there are sort of two camps in the ZK community. The newer MVVM approach suggests the view should push the relevant state to the back end as the user interacts with the front end. This way, the back end never needs to ask for the client state, and when the button is clicked, the values/state are on the server ready to be used.
The other camp binds the client to the server such that the back end always has access to the client Components and when the button is clicked, the values/state can easily be retrieved by interacting with the components.
Another approach is more like what I was talking about in my previous answer, to not bind the back end to the client at all but to rely on event data as much as possible. I favor this approach where it is sufficient.
Now, you're free to choose your favored approach and ZK has lots of documentation on how to work in either of these camps. The question then is where is the client state stored on the server (either pushed there by the client in MVVM or bound there in MVC). I don't think that's a question that can be solved here, that's a software engineering challenge. I personally suggest you take on standard ZK patterns so as not to but heads with the framework. If you really want to go your route, you can grab a reference to the Listbox on the fly like so:
public class Foo {
public static final String LISTBOX_ID = "myListbox";
public void renderListbox(Component parent, MyItem items) {
Listbox listbox = new Listbox();
listbox.setId(LISTBOX_ID);
listbox.setParent(parent);
for (MyItem item : items) {
listbox.appendItem(item.getName(), item);
}
}
}
public class Bar {
#Listen(Events.ON_CLICK + " = #saveButton")
public void saveButtonClicked(Event event) {
Component saveButton = event.getTarget();
Listbox listbox = (Listbox) saveButton.getFellow(Foo.LISTBOX_ID);
Set<Listitem> selection = listbox.getSelectedItems();
// do something
}
I have a page that contains multiple topics in accordion.
How can I post a link (on social media or other places) so when the user clicks it can view the topic I want without making him choose the desired one to view it?
The website is built in Joomla 2.5 using its native (mootools) accordions.
A temporary solution came to my mind is to make single pages containing only the content I want, but it won't help them view the other topics contained in the same page, unless the user clicks the same category.
MooAccordion has a display option. You could use like:
window.addEvent('domready', function () {
var index = window.location.search; // get query string
index = index.replace("?", ''); // remove the ?
index = index.length ? index : 0; // in case there in no query, display first
var myAccordion = new Fx.Accordion($('accordion'), '#accordion h2', '#accordion .content', {
display: index // the actual behavior you are looking for
});
});

So you could try these links as demo:

I have the following fragment in a web component:
<div id="mycodes">
<template iterate='code in codeList'>
{{code}}
</template>
</div>
And in a Dart file, codeList is populated when the user clicks on a button:
void onMyButtonClick(Event event) {
HttpRequest.getString('http://getData').then((response) {
mylist = json.parse(response);
for(var code in mylist){
codeList.add(code['c']);
}
}
The problem is that I don't see data on first click. I need to click the button twice to see data.
But if I fill codeList manually (not from network data) as shown below, then I see the data on first click:
void onMyButtonClick(Event event) {
codeList.add("data 1");
codeList.add("data 2");
}
}
I need the template to iterate after the network data is available. It appears that event loop has already done its job of painting a page before the network data becomes available through future object.
Is there a way to refresh the page after model is updated in dart?
The reason your codeList currently populates if you add it with the on-click event is because the current web_ui has 'watchers' which automatically are called when an event happens. You then populate the list synchronously. However one of the downfalls of watchers is exactly your use case, when the data is updated asynchronously then the watchers don't reflect changes in time.
As a result the watchers are being phased out and replaced with observables. Observables allow us to flag a variable to be watched for reassignment and when that happens it will cause the view to change. For example:
#observable int x = 0;
// ...
x = 1;
When the x = 1 is called later in the code it automatically triggers the views to update. This leaves us with one problem however. When you are adding to a list, you are not reassigning the value itself. As such, observables also offer a function to convert a list to an observable list (this also works for maps).
For instance if you changed your declaration of codeList to something like the following, then when you add to the list later it will update accordingly.
var codeList = toObservable([]); // Assuming it starts with an empty list
// or
var codeList = toObservable(_startCodeList); // if you already have a list
Also see the Dart Tutorial: Target 7 for more information on using #observable and toObservable.
For more in-depth information, check out the article on Observables and Data Binding
You need to mark the fields you want WebUi to monitor with the #observable annotation. Otherwise you only get the initial value not any subsequent updates.
You can do this either directly on the object declaration or you can make the entire class as observable and all its fields will then be observed.
For an example see http://www.dartlang.org/docs/tutorials/custom-elements/#using-two-way-data-binding
