Custom Cursor and Drag Image in 1.4 DnD
What is the proper way to provide a custom cursor and drag image in 1.4 DnD? Say we initiate the drag on a component that supports data transfer (such as a JTree).
Well, this is strange. My app was locking up (100% CPU) when using DND from windows Explorer.
I noticed that another part of the same appliction was working perfictly. The difference: JFrame .vs. JDialog. I switched the offending JDialog to a JFrame and all works perfictly now!
java version "1.4.0"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0-b92)
Java HotSpot(TM) Client VM (build 1.4.0-b92, mixed mode)
I would like to switch back at some point, but my g.setXORMode() problem is a much bigger issue for us. (That is, once you enter the XOR mode, you can not go back!)

I created a Pages document inserting 2 columns using 1) Inspector 2) Layout 3) columns. How do I decrease the height of the column. Have tried to use the cursor and drag down the top border, but that does not reset/decrease the top border.
Set your columns back to one for the moment. In layout mode, insert a Text box. Place it in the upper left corner of your document, and drag down and right to the size of the container for your two columns. Click inside the Text Box, and now bump up your columns to 2. Your two columns are now contained in this resizable Text Box.

Hey guys,
My flash project uses a custom cursor which works fine and is above all my other flash elements. However when I use components such as a combo box, the combo box drop down list is in front of my custom cursor so that the user cannot see the custom cursor when interacting with these kinds of components. Can anything be done to ensure that my custom cursor graphic stays on top of even the native flash components?
Thanksuse the swapDepths() method of movieclips to adjust the
apparent depth of you cursor. (you can use the getDepth() method of
movieclips to find the depth of your combobox.): -
Can you use a custom cursor with drag and drop?
Hi there! I'm a newbie flash user and working on a simulation for a graduate course in instructional design. I'm using Flash Professional CC on Mac. Here's what I'm trying to do. I have several draggable sprites on the stage and three target sprites. I have specified the original x,y locations of the sprites and have set the end x,y locations as those of each of the three targets. Items must be dragged to one of the three targets.
Some questions:
1. Can I specify more than one End x,y location for a draggable sprite? I'm creating a lesson to teach kindergartners how to sort lunchroom waste. If they have a napkin, for example, it could either go into the compost OR into the recycling. In cases like this where an item could really be placed into more than one bin, I want them to get it right if they do either of those things, rather than forcing them to choose which one.
2. To make my project more "fun" for kids, I wanted to customize the cursor with a graphic of hand. When I tried this in the flash file it works perfectly until I add the drag and drop functionality for the wasted items. Then the cursor will more around but not pick up any items. Once I revert back to the standard pointer, the correct drag and drop functionality is restored.
3. I have it set to snap back to the original location if learner attempts to drop the item on the wrong target. I want to be able to play a sound file when that happens, as well as play a sound file when it lands on the correct target, as well as shrink the item and change its opacity so that it appears invisible. I want to give the illusion of it being placed into the bin. I have no idea as to the proper way to code these events so that they happen.
4. I've watched dozens of hours of youtube tutorials before coming here. I'm a quick study, but am very new to action script. In one of the videos the developer showed referencing an external action script file which I don't think is an option in CC. The coding method he used seemed much more streamlined and "clean" than the chunks I'm working with now. Is there an easy way for me to code information about these objects than the way I've got it here now? I hate starting new things with bad habits. The perils of self-teaching.
Thanks!

Adding a custom cursor to a panel
HI, I am making a game where i want clicking a radio button to change the cursor image. I have figured out how to create a custom cursor, and even change the current cursor to it. The problem im having is i want to change it while the program is running. I can say somthing like frame.addCursor(cursor) but that sets it permenantly. What i would like is to add it to a panel during run-time. If anyone knows how i would go abou this i would be gratefull.
ThanksDo u mean, upon selecting the radio button, the cursor must be changed to the customized one?
If it is so,
u add the snippet in the itemStateChanged() event....of the radiobutton
i.e.,
public void itemStateChanged(ItemEvent ie)
if(ie.getStateChange() == ItemEvent.SELECTED)
myPanel.setCursor(Toolkit.getDefaultToolkit().createCustomCursor(CursorImg, new Point
(0,0), "MyCursorImg"));
CursorImg - the image to display when the cursor is actived
new Point(0,0) - hotSpot
MyCursorImg - a localized description of the cursor, for Java Accessibility use
else
myPanel.setCursor(Cursor.getPredefinedCursor(Cursor.DEFAULT_CURSOR));

InDesign CS6 DPS click and Drag feature?

I used the code snippets to create a custom cursor and it works well. What if I want that cursor to change when it's clicked? Can I do that easy enough? Thanks.
you can use a stage mousedown listener to make it appear your cursor was clicked.

I'm using this to create a custom cursor and to use a mouse click event on a movieclip:
stop();
Mouse.hide();
stage.addEventListener(MouseEvent.MOUSE_MOVE,follow);
function follow(evt:MouseEvent)
cursor_mc.x = mouseX;
cursor_mc.y = mouseY;
volgendePijlClip.addEventListener(MouseEvent.CLICK, pijlEventClip);
function pijlEventClip(event:MouseEvent):void
trace(1)
At first it didn't work for me, but I found out that was because the custom cursor was over its registration point. Which was made equal to the mouse's location. So when the mouse was clicked on the movieclip-button, it was actually clicking on the custom mouse cursor itself, so the click on the 'volgendePijlClip movieclip wasn't picked up on.
I solved it by moving the custom cursor slightly away from it's registration point, so it would appear slightly of mouseX/mouseY. Close enough to act as cursor, but away of the cursor enough so the hidden mouse cursor could pick up a click on 'volgendePijlClip'.
Was wondering if there still was a way for a custom cursor to be over it's registration point and have the hidden mouse cursor still pick up on clicking on objects beneath the custom cursor?assign its mouseEnabled property to false:
cursor_mc.mouseEnabled=false; -

Custom cursor using image gets resized bigger
I have created a custom cursor using the following code:
ClassLoader cl = this.getClass().getClassLoader();
Toolkit tk = Toolkit.getDefaultToolkit();
Image im = tk.getImage( cl.getResource("images/wallcursor.gif"));
Cursor Custom_Cursor = tk.createCustomCursor(im,new Point(9,9),"Drawing wall");
draftGrid.setCursor( Custom_Cursor );The cursor is loaded and it works, however - the image I use for the cursor is resized so it gets too big. Any clues on why this happens?
btw; draftGrid is one of my own classes that extends JComponent.
- bjornThanks for your replies guys.
I tried your code KPSeal, and it works in resizing the cursor image back to its original size. However, a gray square of size 32,32 (which is returned by getBestCursorSize()) is shown round the cursor.
Here is the updated code (yours hade some minor bugs)
Image im = tk.getImage( cl.getResource("images/wallcursor.gif"));
try {
tracker.addImage(im, 0 );
tracker.waitForID(0);
} catch( InterruptedException ie ) {
ie.printStackTrace();
int w = im.getWidth(this);
int h = im.getHeight(this);
int pw = Toolkit.getDefaultToolkit().getBestCursorSize(w, h).width;
int ph = Toolkit.getDefaultToolkit().getBestCursorSize(w, h).height;
System.out.println("w="+w+", h="+h+" - pw="+pw+", ph="+ph);
Image cim = createImage(pw, ph);
cim.getGraphics().drawImage(im,0,0, this);
Cursor Custom_Cursor = tk.createCustomCursor(cim,new Point(0,0),"Drawing wall");
draftGrid.setCursor( Custom_Cursor );The System.out.println statement prints: w=18, h=13 - pw=32, ph=32
If I try to do the createImage with w and h instead of pw and ph the same gray square (32,32) is created, and in addition the cursor's size is too big which was the probem to begin with ...

Implementing drag and drop across components with drag image...
Hey all,
Finally got the hang of drag and drop. Not too hard, but a little time consuming. I found an article showing how to capture and drag a BufferedImage within a JTree. When you click and drag a node, it creates a BufferedImage of the node on screen and "ghosts" it a bit, which has a very appealing effect.
However, when I try to drag this image to a JList component, it disappears. So I created the same affect in the JList component. Now you can drag the image from the tree to the list and vice versa. However, the problem is, the image does not "fly over" the borders of the two components (butted up against each other) with the mouse. The image seems to go under the borders, while the mouse floats above everything.
What I would like to do is be able to drag the image all over the application, perhaps even the desktop in the case of a SDI application. I want to be able to see this image drag from my Java app over the Windows Explorer folder, just like how you can do that with Windows Explorer, dragging an image of the selected node into any app that supports the drop. I know we can handle the "transfer" data from explorer and vice versa, but how to be able to keep an image with the mouse?
My best guess is somehow using the Glass pane, grabbing a ref to its BufferedImage (if that is even what is there), and drawing the dragged item in that pane. But, then, how will the image move over the desktop outside of the app, where a glass pane is not?
Is there a way to draw on top of anything, anywhere, but still be able to redraw the background as the image moves with the mouse? There are times where the image may be big, so I don't want to have to capture the underlying screen as an image covering the size of the drag image to restore it as the drag image moves around.
Thank you.We know cursors support some degree of transparence because they have shapes other than blocks.
I've done some playing around with
Toolkit.getDefaultToolkit().createCustomCursor(....);The sad news is, it seems that as soon as a pixel's alpha value is greater than 0, it automatically becomes 100% opaque.
The best you can do, is to take your image, and divide it into a pixel-checkerboard, and set the alpha value of alternating pixels to 0.
e.g.
BufferedImage i = new BufferedImage(32, 32, BufferedImage.TYPE_INT_ARGB);
int[] data = ((DataBufferInt)i.getRaster().getDataBuffer()).getData();
boolean on = true;
for (int z=0; z<data.length; z++)
if (on)
data[z] = 0xffffffff;
else
data[z] = 0x00000000;
on = !on;
if (z%32==0) on = !on;
Cursor hazyWhite = Toolkit.getDefaultToolkit().createCustomCursor(i, new Point(0,0), "hw"); -

this.listView1.AllowDrop = true;
this.listView2.View = System.Windows.Forms.View.LargeIcon;
this.listView2.DragDrop += new System.Windows.Forms.DragEventHandler(this.OnDragDrop);
this.listView2.DragEnter += new System.Windows.Forms.DragEventHandler(this.OnDragEnter);
this.listView1.ItemDrag += new System.Windows.Forms.ItemDragEventHandler(this.OnItemDrag);
private void Form1_Load(object sender, EventArgs e)
DirectoryInfo dir = new DirectoryInfo(@"D:\Material\Emoticons");
foreach (FileInfo file in dir.GetFiles())
try
this.imageList1.Images.Add(Image.FromFile(file.FullName));
catch
Console.WriteLine("This is not an image file");
this.listView1.View = View.LargeIcon;
this.imageList1.ImageSize = new Size(32, 32);
this.listView1.LargeImageList = this.imageList1;
this.listView2.LargeImageList = this.imageList1;
//or
//this.listView1.View = View.SmallIcon;
//this.listView1.SmallImageList = this.imageList1;
for (int j = 0; j < this.imageList1.Images.Count; j++)
ListViewItem item = new ListViewItem();
item.ImageIndex = j;
this.listView1.Items.Add(item);
private void OnItemDrag(object sender, System.Windows.Forms.ItemDragEventArgs e)
DoDragDrop(e.Item, DragDropEffects.Move);
private void OnDragEnter(object sender,
System.Windows.Forms.DragEventArgs e)
if (!e.Data.GetDataPresent(typeof(ListViewItem)))
e.Effect = DragDropEffects.None;
return;
var items = (ListViewItem)e.Data.GetData(typeof(ListViewItem));
if (items == null)
e.Effect = DragDropEffects.None;
else
e.Effect = DragDropEffects.Move;
private void OnDragDrop(object sender, System.Windows.Forms.DragEventArgs e)
ListViewItem items = (ListViewItem)e.Data.GetData(typeof(ListViewItem));
if (items != null)
this.listView2.Items.Add((ListViewItem)items.Clone());

Problem Cursor disappears / Drag and Drop doesn't work
Hey everybody,
I have an urgent problem!
Three butterflies are supposed to be dragged in an object. My customized cursor is sort of a landing net to catch these butterflies.
For the cursor I have this code:
cursor_mc.startDrag("true");
Mouse.hide();
My drag and drop code is:
cursor_mc.addEventListener(MouseEvent.MOUSE_DOWN, startMove);
redbutterfly_mc.addEventListener(MouseEvent.MOUSE_DOWN, startMove);
violetbutterfly_mc.addEventListener(MouseEvent.MOUSE_DOWN, startMove);
yellowbutterfly_mc.addEventListener(MouseEvent.MOUSE_DOWN, startMove);
cursor_mc.addEventListener(MouseEvent.MOUSE_UP, stopMove);
redbutterfly_mc.addEventListener(MouseEvent.MOUSE_UP, stopMove);
violetbutterfly_mc.addEventListener(MouseEvent.MOUSE_UP, stopMove);
yellowbutterfly_mc.addEventListener(MouseEvent.MOUSE_UP, stopMove);
function startMove(evt:MouseEvent):void {
redbutterfly_mc.startDrag();
cursor_mc.startDrag();
violetbutterfly_mc.startDrag();
yellowbutterfly_mc.startDrag();
function stopMove(evt:MouseEvent):void {
redbutterfly_mc.stopDrag();
cursor_mc.stopDrag();
violetbutterfly_mc.stopDrag();
yellowbutterfly_mc.stopDrag();
But when I'm clicking on a butterfly my cursor stops to move and stays on the position of the butterfly, which i'm dragging. After dropping it, there is no cursor at all so one doesn't know where the mouse is currently located.
Does someone know why this doesn't work? I'm working currently with a mousefollower, because at the moment this is the only way it works..
The mousefollower code is:
addEventListener(Event.ENTER_FRAME, enterFrameHandler)
function enterFrameHandler(event:Event):void {
cursor_mc.x += cursor_mc.mouseX / 4;
cursor_mc.y += cursor_mc.mouseY / 4;
But now I have the problem that only the yellow butterfly moves even if I'm clicking on the red or the violet...
Please help me!! Thank you in anticipation!You've solved the problem, thank you very much!
Since it seems you know all about actionscript or at least all answers to my questions, I try my luck a further time
If I wanted to collect the caught butterflies in a certain target, for example a flowerpot, where the butterflies can't be removed after dragged in, is this more or less the code for it? I haven't tried it yet but I'm searching the internet for something like that and maybe it is the right thing? And is in this case "myTarget" the name of the picture which is used as the target? Thank you in advance!
function pickUp(event:MouseEvent):void {
event.target.startDrag(true);
event.target.parent.addChild(event.target);
startX = event.target.x;
startY = event.target.y;
function dropIt(event:MouseEvent):void {
event.target.stopDrag();
var myTargetName:String = "target" + event.target.name;
var myTarget:DisplayObject = getChildByName(myTargetName);
if (event.target.dropTarget != null && event.target.dropTarget.parent == myTarget){
event.target.removeEventListener(MouseEvent.MOUSE_DOWN, pickUp);
event.target.removeEventListener(MouseEvent.MOUSE_UP, dropIt);
event.target.buttonMode = false;
event.target.x = myTarget.x;
event.target.y = myTarget.y;
counter++;
