Hello, in this video I will talk about with Bendel books, listeners benefit books one of the most important components you will use in your in your ADF application. I use this component at for at any publication I developed a US ballot box but a box is used to add a quantity with a label. So, if you want to have a block for department and block for in between and you only want to add a title over it, so, we add we use a bounding box. So, this is now try to either been in books and I will show you what is the listener which we sometimes need to use. So, in this listener I just use is the most important components which we usually use in if application So in this printed books, we can right here support mints and you can add them as many books and we can see it is in buoy ease.

We can make this out to be horizontal. Okay, so it was a drag departments here as a table and we can drag city Here is a table. So, this bended box, I need to talk about this, this bear box has in the behavior here, this closure listener, kids crushes or D. This means if you want to disclose the ballot box, this is a listener once you do it so let us now try to run this bitch and I will show you what does this crucial listener mean. So let us now pick the pencil books. So as you can see here penalty Books has like a container here or a block of data and other one and this is the title of separate books. So, we are usually use it as you can see there are a small collapsible icons here we size the label once you braces This means I need to collapse this many books.

If you want to expand it, it will be excellent. So this collapsible or expandable, has a listener. Sometimes you need to write a code if once user make a collapse for something, if you've been in collection, when the splitter you can close the splitter and split the second part. So you can do whatever you want. Once the user in expand or collapse zap and box. So here is the Bennett books.

I will go here into behavior zero disclosure listener So let's add here. listener the bean, dip and then folks it's enough okay. And is there is one feature he and others will show maximize make it always I own my own to to to do something about this this is one of the features that you can maximize abundant books I will show it to you now and let us make this vertical online to be top okay So, this could have been and in this close restaurant here, it's who I am in tip by the way books listener and let us have a look inside the object which will send to the listener. So, the edges here though you will find here is the exhibit. This is if you want to know if the use of collapse it or expand it. So, let us know rancis So, let's have a look in the ballot box.

Okay, so now let's clear the look I need to collapse this you will find here the listener is invoked with value is false. If I expand it you'll find the listener is invoked with value true. So you will be able to know if the user collapses or expenses and you can write your code or your business as you want. This is the listener which we sometimes use in the bounding box. One feature as well as I said if you select the bundle box, and in the other make sure this maximize always it will display here, maximize icons when you bring in it, it will maximize their ballot box to the full screen. This is why I like actually to use it but in books.

It gives a good a good you always frame it has a title. You can work with collapsible if If you want to disable this if you want just Bennett books who's out in a collapsible you can hear in the behavior make it or appearance which can choose closure make it false. If you make it false that case this closer icons will disappear and it will just like a Bennett box was a title without the niccola suite you as you can see just the title and area or both block and dissolve it in a collapsible so you can have some control and even you have a fit if you want to add some buttons here is a pedal box you can find here physical toolbar. So if you add like this, so if you have Put on like this, it it'll save and see. Here you will find the bottom is splayed here.

And you can add any more bottom just what I like Bennett books it has a lot of good features he has a listener you can make a collapsible or not It has a title. So this is one of the most important component here in ADF. When in books so this is the most important listener we use in EDF. So next video I will continue talking about another feature and if so see you and you can see it you
