- - org.flexdock.docking.floating.policy.DefaultFloatPolicy

All Implemented Interfaces:

FloatPolicy
```
public class DefaultFloatPolicy
extends FloatPolicy.NullFloatPolicy
```
This class provides an implementation of the FloatPolicy interface to provide default behavior for the framework. It blocks floating operations for Dockables without any frame drag sources, for already floating Dockables that cannot be reparented within a new dialog, or if global floating support has been disabled.

Modifier and Type	Method	Description
`static DefaultFloatPolicy`	`getInstance()`	Returns a singleton instance of `DefaultFloatPolicy`.
`boolean`	`isFloatDropAllowed(DockingEvent evt)`	Checks the previous `DockingPort` for the specified `DockingEvent` and returns `false` if it is in a floating dialog and contains less than two `Dockables`.
`boolean`	`isFloatingAllowed(Dockable dockable)`	Blocks floating support (returns false) if `dockable` is `null`, if `FloatPolicyManager.isGlobalFloatingEnabled()` returns `false`, or if there are no entries within the `Set` returned by `dockable.getFrameDragSources()`.

```
public static DefaultFloatPolicy getInstance()
```
    Returns a singleton instance of DefaultFloatPolicy.
    
    Returns:
    
    a singleton instance of DefaultFloatPolicy.
  - isFloatDropAllowed
```
public boolean isFloatDropAllowed(DockingEvent evt)
```
    Checks the previous DockingPort for the specified DockingEvent and returns false if it is in a floating dialog and contains less than two Dockables. A floating dialog may contain multiple Dockables, each of which may be dragged out of the current dialog to float in their own dialog. However, if a floating dialog only contains a single Dockable, it makes no sense to remove the Dockable only to float it within another dialog. This situation is caught by this method and the docking operation is blocked.
    
    Specified by:
    
    isFloatDropAllowed in interface FloatPolicy
    
    Overrides:
    
    isFloatDropAllowed in class FloatPolicy.NullFloatPolicy
    
    Parameters:
    
    evt - the DockingEvent to be checked for drop-to-float support
    
    Returns:
    
    false if the DockingEvent is attempting to float an already floating Dockable with no other Dockables in its current dialog; true otherwise.

  - isFloatingAllowed
```
public boolean isFloatingAllowed(Dockable dockable)
```
    Blocks floating support (returns false) if dockable is null, if FloatPolicyManager.isGlobalFloatingEnabled() returns false, or if there are no entries within the Set returned by dockable.getFrameDragSources(). Otherwise, this method returns true.
    
    Specified by:
    
    isFloatingAllowed in interface FloatPolicy
    
    Overrides:
    
    isFloatingAllowed in class FloatPolicy.NullFloatPolicy
    
    Parameters:
    
    dockable - the Dockable to be checked for floating support
    
    Returns:
    
    false if floating is blocked for the specified Dockable; true otherwise.
