TcxRectBasedGeometryObject Members
The base class for persistent classes that store geometry-related information as a TRect record.Constructors
| Name | Description |
|---|---|
| Create(TPersistent,Integer) | Initializes a new instance of the TcxRectBasedGeometryObject class with specified settings. |
| Create(TPersistent,TRect) | Creates a new TcxRectBasedGeometryObject instance from the specified TRect value. |
| Create(TPersistent) | Creates a new TcxOwnedPersistent class descendant instance. Inherited from TcxOwnedPersistent. |
Properties
| Name | Description |
|---|---|
| Bottom | Specifies the vertical offset of the rectangle’s right-bottom corner or the bottom margin, in pixels. |
| Height | Specifies the rectangle’s height, in pixels. |
| Left | Specifies the horizontal offset of the rectangle’s left-top corner or the left margin, in pixels. |
| Owner protected | Provides access to the persistent object to which the current property set or persistent information container belongs. Inherited from TcxOwnedPersistent. |
| Right | Specifies the horizontal offset of the rectangle’s right-bottom corner or the right margin, in pixels. |
| Top | Specifies the vertical offset of the rectangle’s left-top corner or the top margin, in pixels. |
| Value | Specifies geometry information as a TRect value. |
| Width | Specifies the rectangle’s width, in pixels. |
Methods
| Name | Description |
|---|---|
| _AddRef protected | The reference counter increment function of the interfaced property set. Inherited from TcxOwnedInterfacedPersistent. |
| _Release protected | The reference counter decrement function of the interfaced property set. Inherited from TcxOwnedInterfacedPersistent. |
| Assign(TPersistent) | Applies compatible settings from the specified source to the current property set. Inherited from TcxLockablePersistent. |
| AssignTo(TPersistent) | Inherited from TPersistent. |
| BeginUpdate | Postpones setting change notifications to the parent object until an EndUpdate or CancelUpdate procedure call. Inherited from TcxLockablePersistent. |
| CancelUpdate | Re-enables change notifications and delays pending changes made in the component after a BeginUpdate procedure call until the next content or setting change. Inherited from TcxLockablePersistent. |
| ChangeScale(Integer,Integer) | Scales the persistent geometry object using the specified numerator and denominator values. Inherited from TcxGeometryObject. |
| DoAssign(TPersistent) protected | Updates the persistent information container’s class-specific properties with the corresponding values obtained from another persistent information container. Inherited from TcxOwnedPersistent. |
| DoChanged protected | Applies pending changes after an EndUpdate procedure call. Inherited from TcxLockablePersistent. |
| EndUpdate | Applies all pending changes and redraws the parent object after a BeginUpdate procedure call. Inherited from TcxLockablePersistent. |
| Equals(TObject) | Inherited from TObject. |
| GetHashCode | Inherited from TObject. |
| GetNamePath | Inherited from TPersistent. |
| GetOwner protected | Returns the persistent object to which the current property set or persistent information container belongs. Inherited from TcxOwnedPersistent. |
| IsDefault | Identify if geometry information matches its initial state. |
| IsEmpty | Identifies if geometry information corresponds to an empty rectangle or zero margins. |
| IsEqual(TcxRectBasedGeometryObject) | Compares two geometry information containers. |
| IsEqual(TRect) | Compares geometry information to a TRect value. |
| IsNull | |
| LoadFromStream(TStream) | Loads information from the specified stream to the persistent geometry object. Inherited from TcxGeometryObject. |
| QueryInterface(TGUID,Untyped) protected | Provides access to the implementation of the specified interface if the current persistent property set or information container supports it. Inherited from TcxOwnedInterfacedPersistent. |
| Reset | Restores the initial state of geometry information. |
| SaveToStream(TStream) | Saves information stored in the persistent geometry object, to the specified stream. Inherited from TcxGeometryObject. |
| ToString | Inherited from TObject. |
Events
| Name | Description |
|---|---|
| OnChange | Allows you to respond to changes made to the persistent geometry object’s settings. Inherited from TcxGeometryObject. |
