Remarks
Remember to Dispose the object otherwise there is a resource leak, the object contains a reference to the the corresponding JVM object
Constructors
DropTargetListener(IJVMBridgeBaseInitializer)
Initializer used internally by JCOBridge. Do not use directly.
[Obsolete("This public initializer is needed for JCOBridge internal use, other uses can produce unidentible behaviors.")]
public DropTargetListener(IJVMBridgeBaseInitializer initializer)Parameters
initializerIJVMBridgeBaseInitializer
DropTargetListener(params object[])
Generic constructor used by JCOBridge when a derived class needs to forward arguments to the base JVMBridgeBase class.
public DropTargetListener(params object[] args)Parameters
argsobject[]
Properties
BridgeClassName
Java class name to be instantiated
public override string BridgeClassName { get; }Property Value
OnDragEnter
public Action<DropTargetDragEvent> OnDragEnter { get; set; }Property Value
Remarks
Assign a delegate to handle the event without subclassing. If both this handler and a virtual method override are present, the delegate takes precedence. Set to null to delegate to the virtual method.
OnDragExit
public Action<DropTargetEvent> OnDragExit { get; set; }Property Value
Remarks
Assign a delegate to handle the event without subclassing. If both this handler and a virtual method override are present, the delegate takes precedence. Set to null to delegate to the virtual method.
OnDragOver
public Action<DropTargetDragEvent> OnDragOver { get; set; }Property Value
Remarks
Assign a delegate to handle the event without subclassing. If both this handler and a virtual method override are present, the delegate takes precedence. Set to null to delegate to the virtual method.
OnDrop
public Action<DropTargetDropEvent> OnDrop { get; set; }Property Value
Remarks
Assign a delegate to handle the event without subclassing. If both this handler and a virtual method override are present, the delegate takes precedence. Set to null to delegate to the virtual method.
OnDropActionChanged
public Action<DropTargetDragEvent> OnDropActionChanged { get; set; }Property Value
Remarks
Assign a delegate to handle the event without subclassing. If both this handler and a virtual method override are present, the delegate takes precedence. Set to null to delegate to the virtual method.
Methods
DragEnter(DropTargetDragEvent)
public virtual void DragEnter(DropTargetDragEvent arg0)Parameters
DragExit(DropTargetEvent)
public virtual void DragExit(DropTargetEvent arg0)Parameters

InitializeHandlers(Type)
Handlers initializer for DropTargetListener
protected virtual void InitializeHandlers(Type listenerRuntimeType)Parameters
listenerRuntimeTypeType
ListenerShallManageEvent(int)
Invoked from the JVMBridgeListener on each received event to notify the user which can decide to abort the execution for the specific event returning false
protected override bool ListenerShallManageEvent(int eventIndex)Parameters
eventIndexintThe index of the event triggered as returned from AddEventHandler(string, EventHandler) or AddEventHandler<TDataClass>(string, EventHandler<CLRListenerEventArgs<TDataClass>>)
Returns
Remarks
By default every event continues the execution and reads the data from JVM; this implies an extra cost which can be limited using ListenerShallManageEvent(int) or the MASES.JCOBridge.C2JBridge.JVMBridgeListener.ListenerShallManageEventIndex/MASES.JCOBridge.C2JBridge.JVMBridgeListener.ListenerShallManageEventName handlers. Returning false the control is immediately returned to the JVM, anyway the user has received the notification. It can be useful in scenarios where the user is interested in few events and the other are simply discarded to optimize the execution speed. By default, this function invokes MASES.JCOBridge.C2JBridge.JVMBridgeListener.ListenerShallManageEventIndex, then try MASES.JCOBridge.C2JBridge.JVMBridgeListener.ListenerShallManageEventName if they are set or return true
