In computergraphical user interfaces, drag and drop is a pointing device gesture in which the user selects a virtual object by grabbing it and dragging it to a different location or onto another virtual object. In general, it can be used to invoke many kinds of actions, or create various types of associations between two abstract objects. As a feature, drag and drop support is not found in all software, though it is sometimes a fast and easy to learn technique. However, it is not always clear to users that an item can be dragged and dropped, or what is the command performed by the drag and drop, which can decrease usability. 1ActionseditThe basic sequence involved in drag and drop is Move the pointer to the object. Press, and hold down, the button on the mouse or other pointing device, to grab the objectDrag the object to the desired location by moving the pointer to this oneDrop the object by releasing the button. Dragging requires more physical effort than moving the same pointing device without holding down any buttons. Because of this, a user cannot move as quickly and precisely while dragging see Fitts law. However, drag and drop operations have the advantage of thoughtfully chunking together two operands the object to drag, and the drop location into a single action. 2 Extended dragging and dropping as in graphic design can stress the mousing hand. A design problem appears when the same button selects and drags items. Imprecise movement can cause a dragging when the user just wants to select. Another problem is that the target of the dropping can be hidden under other objects. The user would have to stop the dragging, make both the source and the target visible and start again.

In classic Mac OS the top of screen menu bar served as a universal drag cancel target. This issue has been dealt with in Mac OS X with the introduction of Expos. In Mac OSeditDrag and drop, called click and drag at the time, was used in the original Macintosh to manipulate files for example, copying them between disks3 or folders. 4. System 7 added the ability to open a document in an application by dropping the document icon onto the applications icon. In System 7. 5, drag and drop was extended to common clipboard operations like copying or moving textual content within a document. Content could also be dragged into the filesystem to create a clipping file which could then be stored and reused. For most of its history Mac OS has used a single button mouse with the button covering a large portion of the top surface of the mouse. Convert ODS to XLS Convert your file now online and free this page also contains information on the ODS and XLS file extensions. This may mitigate the ergonomic concerns of keeping the button pressed while dragging. In OS2editThe Workplace Shell of OS2 uses dragging and dropping extensively with the secondary mouse button, leaving the primary one for selection and clicking. Its use like that of other advanced Common User Access features distinguished native OS2 applications from platform independent ports. In HTMLeditThe HTML5 working draft specification includes support for drag and drop. 5 HTML5 supports different kinds of dragging and dropping features including Drag and Drop texts and HTML codes. Drag and Drop HTML elements. Drag and Drop files. Based on needed action, one of the above types can be used. Note that when an HTML element is dragged for moving its current position, its ID is sent to the destination parent element so it sends a text and can be considered as the first group. Googles web based e mail application Gmail supports drag and drop of images and attachments in the latest Google Chrome browser and Apples Safari 5. And Google Image search supports drag drop. On a touch screeneditTouch screen interfaces also include drag and drop, or more precisely, long press, and then drag, e. Phone or Android home screens. OS 1. 1 implements a drag and drop feature which allows the user to touch items and tap with other fingers to drag more within an app or between apps on IPads. 6 On i. Phones, the functionality is only available within the same app that the user started the drag. 7In end user programmingeditDrag and drop is considered an important program construction approach in many end user development systems. In contrast to more traditional, text based programming languages, many end user programming languages are based on visual components such as tiles or icons that are manipulated by end users through drag and drop interfaces. Drag and drop is also featured in many shader editing programs for graphics tools, such as Blender. 8 Drag and drop also features in some video game engines, including Unreal Engine, Game. Maker Studio, Construct 2 and, with expansion, Unity game engine. ExampleseditA common example is dragging an icon on a virtual desktop to a special trashcanicon to delete a file. Further examples include Dragging a data file onto a programicon or window for viewing or processing. For instance, dropping an icon that represents a text file into a Microsoft Word window signifies Open this document as a new document in WordMoving or copying files to a new locationdirectoryfolder,Adding objects to a list of objects to be processed,Rearranging widgets in a graphical user interface to customize their layout,Dragging an attribute onto an object to which the command is to be applied. Dragging a tool to a canvas location to apply the tool at that location,Creating a hyperlink from one location or word to another location or document. Most word processors allow dragging selected text from one point to another. Dragging a series of codeblocks such as in Blender for designing shaders and materials. See alsoeditReferencesedit. File API1. Introduction. This section is informative. Web applications should have the ability to manipulate as wide as possible a range of user input. This specification defines the basic representations for files. Additionally, this specification also defines an interface that represents raw data. The interfaces and API defined in this specification can be used with other interfaces and APIs exposed to the web platform. The File interface represents file data typically obtained from the underlying file system. Blob interface. Binary Large Object a name originally introduced to web APIs in Google Gears. File or Blob reads should happen asynchronously on the main thread. API used within threaded web applications. An asynchronous API for reading files prevents blocking and UI freezing on a user agents main thread. This specification defines an asynchronous API based on an event model to read and access a File or Blobs data. A File. Reader object provides asynchronous read methods to access that files data. The use of events and event handlers allows separate code blocks the ability. An example will be illustrative. In the example below, different code blocks handle progress, error, and success conditions. Read obtain input element through DOMvar file document. Element. By. Idfile. As. Textfile function get. As.

Error The file could not be read2. Terminology and Algorithms. When this specification says to terminate an algorithm the user agent must terminate the algorithm after finishing the step it is on. Asynchronous read methods defined in this specification may return before the algorithm in question is terminated. The algorithms and steps in this specification use the following mathematical operations maxa,b returns the maximum of a and b. Web. IDL Web. IDL. This operation is also defined in ECMAScript ECMA 2. Web. IDL Web. IDL. This operation is also defined in ECMAScript ECMA 2. Mathematical comparisons such as lt less than, less than or equal to, and greater than are as in ECMAScript ECMA 2. The term Unix Epoch is used in this specification to refer to the time 0. UTC on January 1 1. T0. 0 0. 0 0. 0Z ISO 8. ECMA 2. 62 ECMA 2. The Blob Interface and Binary Data. A Blob object refers to a byte sequence. ASCII encoded string in lower case representing the media type of the byte sequence. Each Blob must have an internal snapshot state.

When the Blob constructor is invoked. If invoked with zero parameters. Blob object consisting of 0 bytes. Otherwise, the constructor is invoked with a blob. Parts sequence. Let a be that sequence. Let bytes be an empty sequence of bytes. Let length be as length. For 0 i lt length, repeat the following steps Let element be the ith element of a. If element is a USVString, run the following substeps Append the result of UTF 8 encodings to bytes. Note The algorithm from Web. IDL Web. IDL replaces unmatched surrogates in an invalid utf 1. UFFFD replacement characters. Scenarios exist when the Blob constructor may result in some data loss. If element is a Buffer. Source, get. a copy of the bytes held by the buffer source, and append those bytes to bytes. If element is a Blob. The type of the Blob array element is ignored and will not affect type of returned Blob object. If the type member of the optional options argument is provided. Let t be the type dictionary member. If t contains any characters outside the range U0. U0. 07. E. then set t to the empty string and return from these substeps. Convert every character in t to ASCII lowercase. Return a Blob object referring to bytes as its associated byte sequence. Constructor Parameters. The Blob constructor can be invoked with the parameters below A blob.
