The GTK+ Drag-and-Drop Mechanism
ثبت نشده
چکیده
Drag-and-drop (DND, for short) is an operation in applications with graphical user interfaces by which users can request, in a visual way, that running applications exchange data with each other. To the user, in a drag-and-drop operation, it appears that data is being dragged from the source of the drag to the destination of the drag. Because applications are independent of each other and written without cognizance of who their partners will be in a DND operation, for DND to work, there must be underlying support by either the operating system or the windowing system.

Drag and Drop: Influences on the Design of Reusable Software Components
The fundamental unit of large scale software construction is the component. A component is the fundamental user interface object in Java. Everything you see on the display in a java application is a component. The ability to let users drag a component from the Interface and drop into your application is almost a requirement of a modern, commercial user interface. The CBD approach brings high co...
متن کاملStudy of Torque, Drag and Hydraulics of a Deviated Drilled Well using Drilling Office Software
Rotational drilling was a revolution in drilling technology. It made the drilling process more efficient and faster and more depth of well could be achieved through rotation method. Besides all of its advantages, the rotation approach induced some problems like pipe sticking and downhole cleaning to the drilling procedure. Hole cleaning and reduction of torque and drag seems to be vital in incl...
متن کاملVers des systèmes de fenêtrage distribués : l'évolution du drag-and-drop
This work examines the interactions at stake in environments where several display surfacesand pointing devices are used. These environments can be distributed or not. We are moreparticularly interested in drag-and-drop like techniques in the context of wall-size displays. Drag-and-drop is probably the most emblematic and widespreadly used technique of directmanipulation paradigms. ...

In current Web browsers, there is no uniform way to specify that a user clicking on a link will be presented with an editable view of a Web Distinguished Authoring and Versioning (WebDAV) server. For example, it is frequently desirable to be able to click on a link and have this link open a window that can handle drag-and-drop interaction with the resources of a WebDAV server. This document spe...
متن کاملDrag Reducing Polymers in Vascular System: Viscosity Measurement and Polymers Types and Concentrations
Toms (1949) discovered that if a very small amount of drag reducing polymers (DRP) are added in the flow, approximately 10 ppm by weight or less, a substancial reduction in pressure drop at a given flow rate resulted. Then, since 1948, the phenomenon of drag reduction have been studied by many researchers with the objective of understand the drag reduction mechanism. In the last decades, the dr...
