- Method Detail
  - getProperties
```
public Map<Object,Object> getProperties()
```
    Returns a map containing all properties in this handle. Properties allow the editor to freely attach any kind of semantic information to a handle. When the handle creates a TLspEditOperation object, the latter will contain a copy of these properties. This allows the editor to recover this semantic information in its edit method.
    
    Returns:
    
    a map containing all properties of this handle
  - getCursor
```
public Cursor getCursor()
```
    Returns the cursor for this handle. In practice, this cursor is used when this handle is active, or when it has focus.
    
    Returns:
    
    the cursor for this handle.
  - getCursorFX
```
public javafx.scene.Cursor getCursorFX()
```
    JavaFX equivalent of getCursor(), used when this handle is active in a JavaFX view. If no JavaFX cursor has been set, this method will attempt to create a JavaFX counterpart of the AWT cursor. This will work for the built-in cursors, but any custom cursors will be replaced with the default cursor instead.
    
    Returns:
    
    the JavaFX cursor for this handle

    2020.0
    
    See Also:
    
    setCursorFX(javafx.scene.Cursor)
  - setCursor
```
public void setCursor(Cursor aCursor)
```
    Sets the cursor for this handle.
    
    Parameters:
    
    aCursor - the cursor to be used by this handle.
  - setCursorFX
```
public void setCursorFX(javafx.scene.Cursor aCursor)
```
    JavaFX equivalent of setCursor(Cursor). Sets the cursor to be used by this handle if it is active in a JavaFX view.
    
    Parameters:
    
    aCursor - the JavaFX cursor to be used by this handle
    
    Since:
    
    2020.0
    
    See Also:
    
    getCursorFX()
  - getPriority
```
public int getPriority()
```
    Gets the priority of a handle. Higher priority indicates that this handle should request focus before focus is requested for handles with lower priority.
    
    Returns:
    
    the priority of this handle.
  - setPriority
```
public void setPriority(int aPriority)
```
    Sets the priority of this handle.
    
    Parameters:
    
    aPriority - the handle's new priority
    
    See Also:
    
    getPriority()
  - isActive
```
public abstract boolean isActive()
```
    Checks whether this handle is active. When a handle is active, it will be the first candidate to receive events. If a handle is inactive, it might still receive events (possibly making it active) if all other active handles didn't process an event.
    
    Returns:
    
    true if active, false otherwise
  - getStyleTargetProviders
```
public abstract List<ALspStyleTargetProvider> getStyleTargetProviders(TLspHandleGeometryType aType)
```
    Returns a style target provider that can generate geometry for the given visual editing component type, or an empty list if no geometry can be generated for the given type. TLspEditHandleStyler allows you to register different styles for each visual component type.
    
    Parameters:
    
    aType - a visual editing component type
    
    Returns:
    
    a list of style target providers, or an empty list if no style targets can be created for the given visual editing component type
