My TreeItems are links that open up images in a modal component. Id like to use the endIcon property to display a CircularProgress when the image is being loaded, then unload after the image is loaded. I use OnLabelClick event to get the image, but in the object event.target properties I see nothing that would give me access to that TreeItems's endIcon.
How would I get it?

I'm trying to configure a few settings in a converse.js chatbox (title, removing avatar, chatbox width) PRIOR to it "rendering" and displaying the chatbox.
While not explicitly saying so, I had figured that the "chatBoxInitialized" event would fire AFTER the chatbox object was created, but prior to rendering and displaying.
What I'm finding is that when my handler function for that event is called, the chatbox is already displayed, so clearly my understanding of "chatboxinitialized" is incomplete. Inside the handler, I have used available methods in chatbox object such as
chatbox.setChatBoxWidth(350);
chatbox.model.attributes.fullname = data;
to set chatbox attributes but while the statements execute and have a momentary effect, as soon as the handler function completes, something is setting those values back, and the box "re-renders" and displays as it was before my function ran.
Is there a more appropriate event to register for so these values can be set prior to chatbox rendering? Are there more appropriate "chatbox set functions" that can be used to properly set such things as size, and turn off avatars, rather than just reaching into DOM directly and manipulating after the fact?
Any help would be appreciated.
If you look at the code, you'll see that chatBoxInitialized gets triggered after the chatbox's HTML has already been rendered.
See here: https://github.com/jcbrand/converse.js/blob/393bbe020e45ccd2abe10683117a8f854dea9145/src/converse-chatview.js#L281
Looking at the code, I don't see any event that's triggered after the chatbox has been created, but before it's rendered.
However, in the current master branch of converse.js (to be released soon), you can set the fullname after the chatbox has been created, and it will then appear properly.
You're however setting it wrong. With Backbone.js you must use get and set and not the attributes property.
So this:
chatbox.model.attributes.fullname = data;
must be changed to this:
chatbox.model.set({'fullname': data});
Concerning setting the chatbox width, I think the best way to do that is to set the relevant Sass variable, see here:
https://github.com/jcbrand/converse.js/blob/393bbe020e45ccd2abe10683117a8f854dea9145/sass/converse/_variables.scss#L111
Then run make css to generate new CSS.
I have a Panel and a Image inside this Panel.
In onAfterRender I want to change the defaultModel of the Image.
#Override
protected void onAfterRender() {
super.onAfterRender();
previewImage.setDefaultModel(new Model<String>(newUrl));
}
But this has no effect. The purpose is to display a placeholder and when the Panel is rendered, then change its src
onAfterRender() is a callback executed right after the current Component has been rendered, i.e. it has contributed its part of the final HTML sent to the browser.
It is not very clear what you want to achieve with this placeholder.
In case you want to show a placeholder and then lazily load the real image then you can use AjaxLazyLoadPanel from wicket-extensions. Or you can use JavaScript to replace the placeholder once the image is loaded by the browser (img.addEventListener('load', ...).
onAfterRender() is usually used to render something right after the content/body rendered by this Component, but it cannot be used to change it.
I'm using modal dialog. I'm working with two modal. User Model and STATE Model where
User is Parent model and state/create is open in modal dialog.
when I'm creating new User, I have select state name from drop-down, if it is not listed in dd then it will create state by clicking add new state and open in modal dialog and create state.
Issue is after create new state parent page is refresh and all the data which I have added are removed.
Kindly guide me. I have created modal dialog by below link
Not sure if I understand your problem correctly because there is no example code. But if you have separate form to add new state then you can submit that form with ajax using beforeSubmitevent of ActiveForm.
An example of beforeSubmitevent implementation you can find in this issue
Also in your controller action you will have to set response type to json like following
\Yii::$app->response->format = \yii\web\Response::FORMAT_JSON;

Using Adobe Experience Manager 5.6.1 (AEM) (Formerly CQ5) I am trying to create a new tab similar to the Image tab in Page Properties. It would be titled "Logo".
I basically just copied the Image tab to create a logo tab and renamed the paths to reflect the logo purpose. For instance, I set the fileReferenceParamater to ./logo/fileReference and requestSuffix to /logo.img.png.
When I edit the properties, I can drag an image into the tab just as I can with the "Image" tab, however, the image never appears there. I am guessing this is because the default image handler is not picking up the request. The error is:
Cannot serve request to
/content/my-site/home-page/en_us/jcr:content/logo.img.png in
org.apache.sling.servlets.get.DefaultGetServlet
When I looked at the content node there was no sling:resourceType. When I added a resource type of foundation/components/adaptiveimage then it worked. However, I noticed that the "Image" node didn't have a sling:resourceType. I guess the img.png.java servlet in the foundation page is handling that request.
I tried creating a logo.img.png.jsp file in my page component to handle the request, but that didn't seem to work.
How can I get AEM to either add the sling:resourceType or to handle the request?
I was facing the similar problem and I found a simpler way to resolve. All you need to do is to add a hidden xtype under the your logo image as below:
<yourlogo
jcr:primaryType="cq:Widget"
<-- other properties -->
xtype="html5smartimage">
<items jcr:primaryType="cq:WidgetCollection">
<resType
jcr:primaryType="cq:Widget"
ignoreData="{Boolean}true"
name="./logo/sling:resourceType"
value="foundation/components/image"
xtype="hidden"/>
</items>
</yourlogo>
Well, after some time experimenting, this is what I ended up doing to get this to work. If there is an easier way, I would be happy to know it.
First, I copied the /libs/foundation/components/page/img.png.java file and added it to my compiled package with some modifications.
#SlingServlet(
resourceTypes = "sling/servlet/default",
selectors = "imgnode",
extensions = {"png","jpg","jpeg","gif"},
methods = "GET"
)
public class SimpleImageServlet extends AbstractImageServlet {
Where img.png.java had the following line:
Image image = new Image(c.resource, "image");
I changed it to:
Image image = new Image(c.resource);
This relies on SCR annotations to generate the OSGi configuration so that this servlet will handle image requests having the imgnode selector. Instead of looking for a child image node it just expects the current resource to be an image.
Second, I added a component to the body.jsp overlay of the page component, like so.
<cq:include path="logo" resourceType="/apps/my-site/components/logo" />
This maps the logo path to a component for rendering.
Third, within the logo.jsp on the component I set the selector to imgnode rather than img.
Image img = new Image(resourcePage, "logo");
img.setSelector("imgnode");
I believe this step would be similar if the adaptiveimage were overlayed. You just need to render out URLs that include the imgnode selector.
Fourth, I setup the logo image dialog tab in page properties to use the expected requestSuffix and set the other properties to point to the logo sub-node.
Examples:
requestSuffix = "/logo.imgnode.png"
fileReferenceParameter = "./logo/fileReference"
Fifth, I made sure that the image dialog tab for the /apps/my-site/components/logo component pointed to itself.
Examples:
requestSuffix = ".imgnode.png"
fileReferenceParameter = "./fileReference"
Now whether it is in page properties, component editing, or final rendering, the image is handled appropriately.
this is a bit of a nuisance with using the image widget controls--only the image component nicely handles the data, and the servlet that handles ".img" is tied to the image component resourceType.
the easiest thing is to just use the value of the fileReference property instead of referencing the image as part of the page. since you're using assets from DAM, this is a reasonable approach.
this doesn't address the issue with a user uploading an image directly. i wanted to suggest having a hidden field like "./logo/sling:resourceType", but testing that locally resulted in an error when trying to save the dialog.
another approach is the following:
<sling:include resourceType="foundation/components/adaptiveimage" resource="${resource.path}/logo" />
(assuming resource is jcr:content). this is effectively the same as adding a sling:resourceType, but there are at least 2 downsides:
the image becomes authorable at that point as opposed to in the dialog
this method only works for rendering a normal tag. it won't work for any sort of background image
I have a form within a tab. It is second tab so it doesn't render until you open it.
I have tried to submit data to the form with Ext.getCmp('DetailsForm').getForm().setValues(selections[0]); but it says that it is not a function. Probably because it is not rendered yet. What I have to do?
Set the deferredRender config property of your Ext.tab.Panel to deferredRender: false
That will force the rendering of all tabs instead of just active ones. Now the form will be there. As mentioned before I recommend you also to use myTabPanelRef.down('from').getForm().setValues(selections[0]); to access the form.
subscribe to the second tabs show event OR painted event
then look for the form preferably by using .down() method as this wont look with in the entire DOM.
set the values
Use render event of form panel.
Your code will be something like this -
Ext.getCmp('DetailsForm').on('render', function(){
this.getForm().load(selections[0]);
});
