## Properties
### Property hasChanged
**Definition**: `ModelCenter/src/ModelCenter.odl` (line 1)
```
boolean ModelCenter::IVariable::hasChanged
```
Boolean which indicates if the variable has changed since the last time the boolean was reset. Typically used only by Plug-Ins for their own variables (to avoid conflicting use by different Plug-Ins , macros, or tools). Set the value to false and it will automatically flip to true any time the value changes.
**Return type**: boolean
### Property hide
**Definition**: `ModelCenter/src/ModelCenter.odl` (line 1)
```
boolean ModelCenter::IVariable::hide
```
Hides the variable from the User Interface. Variable will not be visible in Component Tree, Data Explorer, or Data Monitors.
**Return type**: boolean
### Property OwningComponent
**Definition**: `ModelCenter/src/ModelCenter.odl` (line 1)
```
LPDISPATCH ModelCenter::IVariable::OwningComponent
```
Gets the component that owns this variable.
**Returns**:
IDispatch\* to an [IComponent](interfaceModelCenter_1_1IComponent.md#interfaceModelCenter_1_1IComponent) object.
**Return type**: LPDISPATCH
## Public functions
