public interface FloatPolicy
This interface describes a set of method used to determine how floating
events should be handled. Classes implementing this interface should be
plugged into to the FloatPolicyManager
to affect floating behavior of
the framework at runtime.
Nested Class Summary | |

static class |
FloatPolicy.NullFloatPolicy
Provides a default implementation of the FloatPolicy interface. |
Method Summary | |
---|---|
boolean |
isFloatDropAllowed(DockingEvent evt)
Indicates whether floating should be allowed for the specified DockingEvent at the end of a drag operation. |
boolean |
isFloatingAllowed(Dockable dockable)
Returns true if floating should be allowed for the specified
Dockable . |
Method Detail |
---|
boolean isFloatingAllowed(Dockable dockable)
true
if floating should be allowed for the specified
Dockable
. This method will be invoked by the
FloatPolicyManager
at the beginning of a drag operation to
determine whether or not floating support will be enabled for the
Dockable
as a result of the drag. If this method returns
false
, floating will not be allowed for the drag operation
against the specified Dockable
.
dockable
- the Dockable
to be checked for floating support
true
if floating should be allowed for the specified
Dockable
; false
otherwise.boolean isFloatDropAllowed(DockingEvent evt)
DockingEvent
at the end of a drag operation. The
FloatPolicyManager
will catch all attempts to float a
Dockable
at the end of a drag operation and invoke this method on
all installed FloatPolicies
. If any of them returns
false
, the docking operation will be canceled.
evt
- the DockingEvent
to be checked for drop-to-float
support
true
if floating should be allowed for the specified
DockingEvent
; false
otherwise.
