Speaking about the graphical user interface, one cannot but say about the technology Drag and Drop(literally: Pull and Throw).
This technology is based on dragging and dropping GUI elements from the source to the destination. The interface is only accessible with a mouse (touchpad, trackball) or touch screen.
A draggable element is grabbed and held with the mouse while being dragged to a different location at the same time. When the mouse is in the correct position, the mouse button is released, releasing the object.
However, the Drag'n Drop interface should be distinguished from interface controls that have methods in their methods that are responsible for moving, implemented in the same way. For example, a window (form) has the ability to move around the screen (by dragging the title area). ScrollBox has a scroll slider. But in both examples, dragging is an internal (for the component) action (event) and does not affect other objects in the system in any way.
The drag and drop interface is only applicable for moving an object from container to container, even if the containers are heterogeneous. For example, dragging a file from a folder into an email.
Drag and Drop interface in web technologies
Using Interfaces Drag and Drop in web technologies has been a breakthrough in . There are offline Drag and Drop editors (for example, DreamWeaver) and online (for example, any modern website builder.
Where GUI elements are implemented using pseudographics) using the mouse or touch screen.
The method is implemented by "capturing" (by pressing and holding the main ( first, more often the left) mouse button) of an object displayed on the computer screen, programmatically available for such an operation, and moving it to another place (to change the location) or “throwing” it onto another element (to call the corresponding action provided by the program). In relation to windows (also capable of being moved in a similar way) this term usually not used.
Basic actions and the most simple examples drag-and-drop actions are: moving an object, moving an object in from panel to panel, although in modern operating systems drag-and-drop has been widely used and is one of the main ways to interact with a computer in a graphical user interface.
The following interface elements can be objects for moving: Desktop icons (icons), floating toolbars, program shortcuts in the Taskbar (starting with Win XP), TreeView elements, text string, DataGridView cell., also OLE elements. Objects can move both within a certain area, within one window, between panels of one window, and between different windows.
The drag event must be triggered by some user action. Most often, this action is a left mouse button press on an element (this event is called MouseDown), which can be moved in its container. Some components have their own drag-n-drop start events - for example, the TreeView has an ItemDrag event.
