Form (programming)
Encyclopedia
In component-based programming (Visual Basic
, .NET
WinForms, and Delphi
), a form is an easy way to create a GUI
window. A form contains components and controls, which are a high-level representation of standard GUI widgets; it's easier to manipulate the high-level wrappers than to deal with the underlying API.
At design time, visual controls (buttons, text boxes, and the like) and non-visual components (timers, database connections, and so on) are placed on the form. These controls and components are moved and sized with a mouse, and their properties and event handlers are set with a special grid.
At runtime, automatically generated code creates instances of these controls and components, and sets their properties.
