How to implement Drag and Drop in trees

Hi,
I have two hierarchical tree in a form, i need to drag each nodes form one tree node and drop into another tree, how i possible. am using Forms 6i developer.

Drag-n-Drop is only available in Forms by extending Forms with a Java Bean. In order to use a Java Bean in your form, your form MUST be web deployed; if you are using traditional Client/Server with your Forms 6i then there is no way to implement Drag-n-Drop.
Take a look at: Drag 'n Drop - Oracle Forms PJC and Java Beans. This article was based on using Oracle Forms 9i so you might not be able to implement it in your Forms 6i app.

How to implement drag and drop functionality in a HTML5 webpage using touch events?

Hi all,
     I need to create a webpage having two parts.One part is having set of SVG images into it and other part is having canvas.I need to drag those image onto the canvas allowing same image for multiple times and those images on the canvas are movable inside the canvas only. This webpage is only used in iphone or ipad like touching devices so I need to handle touch events.
     There is already jQuery plugin for drag drop functionality but it is not supported for touch events.
It is only for desktop veriosns.So if you know about any jquery plugin let me know.
     So please help me to carry out this task.

I have tried using the same but still not working.
I have handled touch events like touchstart,touchend,touchmove.
But the problem is when I drag the image from upperbox onto canvas, the clone of that image is creating but the image which I dragged on canvas gets vanished.
I am creating clone because I want to add multiple images onto canvas.

How do I drag and drop an action onto a task flow?

In How to pass View Object bind variable from ADF page John states that
You should also consider dragging-and-dropping the executeWithParams operation on your task flow and wiring it to occur before your page instead of putting it in the page definition of the page itself - this way it is more clear what is happening, and is the recommended approach for 11g apps. When you drag-and-drop the operation, you can use the dialog to bind the parameter to your page-flow-scoped variable by supplying the proper EL there.
How can I drag and drop the executeWithParams method onto a task flow. I am using 11.1.1.5.0 on LINUX?
I'm presuming I a need a method action in my page flow.
I have the following action defined in my page def file:
<action IterBinding="localizedCustomerHierarchyViewIterator"
id="executeQueryWithParamsForLocalizedCustomerHierarchyView"
InstanceName="BusinessRulesAMDataControl.LocalizedCustomerHierarchyView"
DataControl="BusinessRulesAMDataControl" RequiresUpdateModel="true"
Action="executeWithParams">
<NamedData NDName="RootEntityId"
NDValue="#{pageFlowScope.recommendationRule.customerEntityId"
NDType="java.lang.Long" NDOption="3"/>
<NamedData NDName="Language"
NDValue="#{pageFlowScope.recommendationRule.language}"
NDType="java.lang.String" NDOption="3"/>
</action>

In summary, it appears you need the following artifacts in order to initialize a view object from parameters before rendering a .jsff view that relies on that view
1) a method-call in task flow.xml file:
<method-call id="executeWithParamsLocalizedCustomerHierarchyView">
<method id="__5">#{bindings.executeWithParamsLocalizedCustomerHierarchyView.execute}</method>
<outcome id="__12">
<fixed-outcome id="__9">initializedLocalizedCustomerHierarchy</fixed-outcome>
</outcome>
</method-call>
2) a control flow rule in the task flow .xml file whose source is (1) and whose destination is the view for which you want to intiialize a view object that supports an iterator that is bound to a list, tree, etc.
3) an entry for the execute action in the databindings.cpx file
<page path="/WEB-INF/[email protected]calizedCustomerHierarchyView"
usageId="oracle_apps_br_view_RecommendationRulePFPageDef"/>
4) the page def must be defined in the databindings.cpx file
5) the page def needs to define action and iterator and list (or otherwise) that is used in UI.
<iterator id="localizedCustomerHierarchyViewIterator"
Binds="LocalizedCustomerHierarchyView"
DataControl="BusinessRulesAMDataControl" RangeSize="25" Refresh="never">
<sortCriteria>
<sort attribute="Level" ascending="true"/>
</sortCriteria>
</iterator>
<action IterBinding="localizedCustomerHierarchyViewIterator"
id="executeWithParamsLocalizedCustomerHierarchyView"
InstanceName="BusinessRulesAMDataControl.LocalizedCustomerHierarchyView"
DataControl="BusinessRulesAMDataControl" RequiresUpdateModel="true"
Action="executeWithParams">
<NamedData NDName="RootEntityId"
NDValue="#{pageFlowScope.recommendationRule.customerEntityId}"
NDType="java.lang.Long"/>
<NamedData NDName="Language"
NDValue="#{pageFlowScope.recommendationRule.language}"
NDType="java.lang.String"/>
</action>
<list ListOperMode="navigation"
IterBinding="localizedCustomerHierarchyViewIterator"
id="customerLocalizedEntityHierarchyList">
<AttrNames>
<Item Value="EntityName"/>
</AttrNames>
</list>
6) a backing bean that provides the functions to initialize the parameters for execution
The easiest way to get most of this is to drag the ExecuteWithParams from within the view in the datacontrols panel right onto the task flow diagram. The downside is that you are left with some pretty poorly named artifacts...
Did I miss anything?

Drag and Drop for Tree in a Table

I have placed a tree in a table using the example provided in an article "Creating TreeTables in Swing" in java.sun.com. But , instead of using the FileSystem data with which the example was explained , i have passed my own data...Then i created a panel wherein i placed two of these tables with buttons in between.
The buttons are meant for data transfer....The problem is if i implement Drag and Drop support for the TreeTable the Tree embedded in the Table doesn't expand and collapsing properly....
Can there be any reason that if a tree is placed in a Jtable and the drag and drop is enabled using setDragEnabled(true) will it effect the normal behaviour

You can implement DropTargetListener, DragSourceListener, DragGestureListener like the following:
public class MyTree extends JTree
            implements DropTargetListener, DragSourceListener, DragGestureListener {
    public void dragEnter (DropTargetDragEvent event) {
        event.acceptDrag (DnDConstants.ACTION_MOVE);
    public void dragExit (DropTargetEvent event) {
        //System.out.println( "dragExit");
    public void dragOver (DropTargetDragEvent event) {
    public void drop (DropTargetDropEvent event) {
        // place your code for action after drop
    public void dropActionChanged ( DropTargetDragEvent event ) {
    public void dragGestureRecognized( DragGestureEvent event) {
    public void dragDropEnd (DragSourceDropEvent event) {
    public void dragEnter (DragSourceDragEvent event) {
        //System.out.println( " dragEnter");
    public void dragExit (DragSourceEvent event) {
        //System.out.println( "dragExit");
    public void dragOver (DragSourceDragEvent event) {
        //System.out.println( "dragExit");
    public void dropActionChanged ( DragSourceDragEvent event) {
        //System.out.println( "dropActionChanged");
}Hope this can help.

Implementing Drag and Drop Functionality

I'm implementing drag and drop a record from a table to another table.
I already referred below:
http://download.oracle.com/docs/cd/E15523_01/web.1111/b31973/af_dnd.htm#CIHDADFG
But I have a question.
In example 32-5, there is a source like following:
+// And now get the actual data from the dragged model.+
+// Note this won't work in a region.+
DnDDemoData dnDDemoData = (DnDDemoData)dragModel.getRowData();
In this case, 'DnDDemoData' type looks like each project's own suitable row type.
But I don't know what type is suitable in my project.
I use a two VOs for two tables.
So I think it's ViewRowImpl class type, but it's not.
How can I find suitable row type?

Hi Timo,
Could not understand what exactly need to have for this...
// And now get the actual data from the dragged model.
// Note this won't work in a region.
DnDDemoData dnDDemoData = (DnDDemoData)dragModel.getRowData();
Could you please elaborate on this!!!
Thanks,
Vin

How do you drag and drop using mac laptop?

how do you drag and drop using mac laptop?

As said above, you can click down, ons use the other finger to drag the object. I had turned on the setting to use three-finger drag, so you can drag objects with three fingers. To change gesture settings, go to the system preferences>trackpad. Here you can also see all of the gestures of Mac OS X.

How can I drag and drop a Tidal job into another group?

How can I drag and drop a Tidal job into another group? In Tidal Help, it says-
In the Jobs pane, press and hold the Ctrl key and at the same time right-click and either individually select individual jobs within a job group or drag your mouse cursor over a block of jobs that you wish to select. You can only move multiple jobs between job groups if the jobs being moved are on the same level.
Keeping the right mouse button depressed, drag the cursor to the job group that you wish to move the jobs to and release the mouse button.
When moving jobs from one job group to another, you must decide if the moved jobs keep their original job group attributes or assume the calendar and agent characteristics of its new job group.
A confirmation dialog, offers three inheritance options for the jobs moved to the "new" job group parent. Select one of the following options:
However, when I attempt to follow those instructions, it doesn't work at all and there is no indication that it's even trying (i.e., I don't see the selected job following my cursor at all and all I get is the normal menu when you right click anywhere on the screen.)
Is there another way to do this or is there a master setting that needs to be changed so that ability is enabled?
Thanks.

Go into edit mode for the job group group and just manually edit the section for Parent job/Group.
Cheers

How do you drag and drop samples in the ex24 on pro x now that the edit button next to the option tab is no longer there?

how do you drag and drop samples in the ex24 on pro x now that the edit button next to the option tab is no longer there?

Well, it's aggravating seeing foolish limitations to the program. Having some experience in education, offering a professional program in a limited version is condescending to the user and has never been proven to help students move forward. Plus, some of the choices made to keep Logic simple are confounding... "removing the edit button on the EXS24"? That's silly!

How can I drag and drop an item from one Tree control to another in LabVIEW 7.1?

You can use the mouse up and down event on the two tree controls but the problem is making the correct selection in the second tree control. I want to be able to switch over to the selection bar of the second tree control so that I can place my item in the correct position. I know all possible workarounds with double-clicks and so on... but I really want a windows drag and drop.
This is what I have for the moment. Please check the library below. I need to activate the selection bar of the second tree control somehow to get the position in the control. The VI below is written in LV 7.1

Hi Jones,
As far as I know this feature is currently not supported by the Tree control. A workaround, would be to use the vertical position of the mouse in the button up event to determine what line you�re dropping the item.
If you would like the Tree control to include the drag and drop feature, please submit this as a Product Suggestion under the feedback at www.ni.com/contact.
Good luck!
