CustomNumberBox#

Qualified name: delphivcl.CustomNumberBox

class CustomNumberBox#

Bases: CustomEdit

TCustomEdit is the base class from which all edit-box and memo controls are derived. Vcl.NumberBox.TCustomNumberBox inherits from Vcl.StdCtrls.TCustomEdit. All content below this line refers to Vcl.StdCtrls.TCustomEdit. TCustomEdit is the base class from which all edit-box and memo controls are derived. TCustomEdit encapsulates the behavior common to all components for editing text by introducing methods and properties that provide: Basic text editing functions such as selecting text, modifying selected text, and case conversions. Ability to respond to changes in the contents of the text. Access control of the text for making it read-only or introducing a password character to hide the actual value. Do not create instances of TCustomEdit. Use TCustomEdit as a base class when declaring control objects that permit the user to enter or modify text. Properties and methods of TCustomEdit provide basic behavior that descendant classes inherit as well as behavior that components can override to customize their behavior.
