TcxCustomEdit Class

The base class for all editor components.

Declaration

TcxCustomEdit = class(
    TcxCustomEditContainer,
    IcxEditRepositoryItemListener,
    IcxInplaceEditIMEHelper,
    IdxSkinSupport,
    IdxSpellCheckerControl,
    IdxFadingObject,
    IcxEditOwner,
    IdxTouchModeSupport,
    IdxAutomationElementWithRepositoryItem
)

Remarks

The ExpressEditors Library ships with over 40 data editor types you can use as standalone controls for data input forms or in-place editors embedded into container controls (Data Grid, Tree List, Vertical Grid, Pivot Grid, Ribbon UI, etc.). An in-place editor exists (and, therefore, has its own WinAPI handle) only when a user activates it. Otherwise, the target container control displays a static editor image for resource usage optimization.

Most data editors (such as text, spin, or mask editors) are designed to display data in a specific manner and allow users to edit data. Certain editors (such as bar code or formatted label editors) have no data edit functionality.

The TcxCustomEdit class implements the base functionality common to all data editors.

Main API Members

The list below outlines key members of the TcxCustomEdit class that allow you to configure editors.

Appearance Settings

Style | StyleDisabled | StyleFocused | StyleHot | StyleReadOnly

Allow you to define individual appearance settings for different editor states.

Tip

To apply the same style settings to multiple editors, use a TcxEditStyleController component. If you need to apply the same style settings to all editors in your application, you can use a TcxDefaultEditStyleController component.

Specifies if the editor is transparent in GDI render mode.

Clears the editor.

Only data-aware editors publish these API members.

Terminal TcxCustomEdit Class Descendants

Terminal TcxCustomEdit class descendants include all unbound and data-aware editors shipped with the ExpressEditors Library. Do not create TcxCustomEdit class instances. You can derive descendants from the TcxCustomEdit class and override its virtual methods to create custom editors with support for DevExpress Skins and editor integration mechanisms.

Note

Non-editor controls shipped with the ExpressEditors Library are not derived from the TcxCustomEdit class. For example, TcxButton, TcxClock, TcxFilterControl, TcxHeader, and TcxNavigator.
