How Drag and Drop Website builders work
Drag and Drop Website builders enable you to customize data by moving it from one view to another by means of dragging and dropping. This is made possible by a framework which is mainly intended in moving data. But anyway, you can also use the framework for UI actions. Just for instance, you can come up with an application that integrates colors when you drag the color icon into another. But how does drag and drop really works?
The operation starts when you create gestures that will indicate you to start dragging the data. In return, the apps will let you know that you have just started the dragging operation. In order to receive a representation of the data that you are dragging, the system will respond to the app as you move the representation which is indicated by a dark shadow. Once you release this representation, the dragging operations end.
Generally, there are four steps included in a drag and drop website builder.
Started
Upon you start the dragging gesture; the apps will also command the system to initiate the action. At this state, the stratDrag will give you the subject data including the metabase that describes it. Initially, the system will respond to the apps to obtain the representation. After that, the display shadow will be displayed in your device.
Continuing
As you continue the dragging operation, there will also be an intersection of the drag shadow and the View object. With this, the system will send the drag events to the View to the drag event listener. Meanwhile, the listener can modify the appearance of the object. Just for instance, if the drag event signals the entry of the drag shadow, the view will be highlighted in the display.
Drop
To drop the subject icon, you just have to release the representation or the drag shadow. The data will then be retrieved by the bounding box. The listener will be sent as indicated by ACTION DROP. After that, data will be transmitted to the system.
Keep in mind that you will only undergo this process in drag and drop website builder when the drag shadow is dragged within the View objects bounding box provided that they are registered in receiving the events. In cases where in other options are used, there is no ACTIONDROP sent.
End
After releasing the representation, the ACION DROP will be sent along with ACTION DRAG ENDED type. This is to signal that the drag operation has ended. Regardless of the location where you prefer to release the representation or the drag shadow, this operation takes place. The event then is delivered to each listener.
Now that you are aware on the operations in the drag and drop website builder, you can now have an overview on how the framework perform their function to customize and personalize your websites. However, you have to remember that in that they should be coupled with the principle of decent software and best practices. Therefore, you have to be wise in choosing a drag and drop website builder.
