Declaration

property MasterLookAndFeel: TcxLookAndFeel read; write;

Property Value

Type
TcxLookAndFeel

Remarks

Look & feel settings are arranged into at least three levels to determine the appearance of all DevExpress controls in an application:

• The level of an individual control accessible via the control’s LookAndFeel property. If a look & feel option is not set at this level, the control imports the corresponding setting from the global or parent level via the MasterLookAndFeel property.

• The optional level of a parent control accessible via the control’s LookAndFeel property. If a look & feel option is not set at this level, the parent control imports the corresponding setting from the global or another parent level via the MasterLookAndFeel property.

• The global level accessible via the RootLookAndFeel global function, TcxLookAndFeelController, or TdxSkinController component. If a look & feel option is set to the default value, the look & feel painter uses the corresponding global constant value. The RootLookAndFeel.MasterLookAndFeel property always returns nil (in Delphi) or nullptr/NULL (in C++Builder).

• The level of global constants whose values determine the default look & feel settings.

You can use the MasterLookAndFeel property to:

• Identify the default look & feel settings at the current level.

• Customize look & feel settings of a control’s immediate parent.

• Assign another source of look & feel settings to set or change the parent level for a control.

Every DevExpress control or component that serves as a source of look & feel settings must implement the IcxLookAndFeelNotificationListener interface to notify all registered listeners of the following changes:

• Any look & feel property change. A listener control’s appearance updates

• A TcxLookAndFeel class instance destruction. A listener control imports default look & feel settings from the global level once the current source is destroyed.
