DRAGNDROP
Overview
The DRAGNDROP
class provides constants for handling drag-and-drop operations in Servoy. Key operations include COPY
, MOVE
, and NONE
, which allow developers to define behavior for copying, moving, or disabling drag functionality. These constants help streamline interaction handling in custom applications. Additionally, the class defines MIME types such as MIME_TYPE_SERVOY
and MIME_TYPE_SERVOY_RECORD
. These constants ensure proper identification of Servoy objects and records during drag-and-drop operations, enhancing integration and compatibility within the Servoy runtime environment.

Constants Detailed
COPY
Constant for copy drag operation.
Type Number
Sample
function startDrag(event)
{
if(event.getElementName() == "copy")
return DRAGNDROP.COPY;
else if(event.getElementName() == "move")
return DRAGNDROP.MOVE
return DRAGNDROP.NONE;
}
MIME_TYPE_SERVOY
Constant used as mime type for servoy objects.
Type String
Sample
if (event.dataMimeType == DRAGNDROP.MIME_TYPE_SERVOY || event.dataMimeType == DRAGNDROP.MIME_TYPE_SERVOY_RECORD) {
application.output("Dropping is allowed" );
return true;
} else {
application.output("Dropping is not allowed" );
return false;
}
MIME_TYPE_SERVOY_RECORD
Constant used as mime type for servoy record objects.
Type String
Sample
if (event.dataMimeType == DRAGNDROP.MIME_TYPE_SERVOY || event.dataMimeType == DRAGNDROP.MIME_TYPE_SERVOY_RECORD) {
application.output("Dropping is allowed" );
return true;
} else {
application.output("Dropping is not allowed" );
return false;
}
MOVE
Constant for move drag operation.
Type Number
Sample
function startDrag(event)
{
if(event.getElementName() == "copy")
return DRAGNDROP.COPY;
else if(event.getElementName() == "move")
return DRAGNDROP.MOVE
return DRAGNDROP.NONE;
}
NONE
Constant for no drag operation.
Type Number
Sample
function startDrag(event)
{
if(event.getElementName() == "copy")
return DRAGNDROP.COPY;
else if(event.getElementName() == "move")
return DRAGNDROP.MOVE
