Mouse Click Coordinates
Hi,
The question I have is this:
How can I translate the X and Y of a mouse click to the 3D environment? For example, when I click and print out the X and Y, I get coordinates relative to the world (ie. X=213, y= 512). If I wanted to say, click somewhere and have all the rectangles on the screen move to the location of the click, how would I accomplish that?
Thanks in advance,
threeFiddy
Hi,
there are classes which will translate coordinates from Canvas to World. But before you translate anything, you need a concept, how to handle the third Dimension.
This task is discussed in the pdf documentation on http://java.sun.com/products/java-media/3D/collateral/ part 4 chapter 4.6 Picking.

Oliver

Getting mouse click coordinates with image button
I'm using ADF Rich Client components in JDeveloper 11g Technology preview.
I have to get the mouse click coordinates with an image button. In the page I put something like this:
<af:commandButton text="commandButton1" icon="ambiente.jpg"
actionListener="#{prova.listen}" action="#{prova.esegui}" />
In the listener method of the managed bean I try to get the coordinates with this code:
public void listen(ActionEvent e)
FacesContext context = FacesContext.getCurrentInstance();
String clientId = e.getComponent().getClientId(context);
Map requestParams =
context.getExternalContext().getRequestParameterMap();
int x =
new Integer((String) requestParams.get(clientId + ".x")).intValue();
int y =
new Integer((String) requestParams.get(clientId + ".y")).intValue();
but it doesn't work. It seems that there aren't in the request the coordinates of the image point clicked. Is it true? How can I do that with ADF ?Hi,
the mouse position is not part of the request parameters send. You will have to use client side JavaScript for this

X Y Mouse Click Coordinates in the Request Map?
I have a mapping application that layers several images with a clickable top layer. When I wrap the top image in a command link I don't get the x and y coordinates of the mouse click in the request map. So I've had to use a regular command button with an image property. This works fine but doesn't allow me to use partial page rendering to limit the refresh of particular images in the stack. Can the x,y coordinate of the mouse click be returned with straight ADF?
(I"ve included the code for retreiving the x and y coordinates under the jspx code)
<af:panelGroup type="vertical">
<af:objectImage source="#{backing_collect2.activeSource}"/>
<af:objectImage source="#{backing_collect2.baseSource}"
inlineStyle="position:absolute;left:0px;top:0px"
binding="#{backing_collect2.baseImage}"/>
<af:objectImage source="#{backing_collect2.allPointSource}"
inlineStyle="position:absolute;left:0px;top:0px"
binding="#{backing_collect2.allPointImage}"/>
<af:objectImage source="#{backing_collect2.userPointSource}"
inlineStyle="position:absolute;left:0px;top:0px"
binding="#{backing_collect2.userPointImage}"/>
<af:objectImage source="#{backing_collect2.activePointSource}"
inlineStyle="position:absolute;left:0px;top:0px"
binding="#{backing_collect2.activePointImage}"/>
This following fails to return x and y in the request Map, imageMapType="server"
attr on objectImage does not help
<af:commandLink actionListener="#{backing_collect2.processClick}"
action="#{backing_collect2.collectAction}"
inlineStyle="position:absolute;left:0px;top:0px">
<af:objectImage source="#{backing_collect2.activeSource}"
inlineStyle="position:absolute;left:0px;top:0px"/>
</af:commandLink>
I have to use the following regular command button to get x, y click coordinates in the request map. But using this component makes its impossible to use partial page rendering to limit refreshes of the images above.
<h:commandButton image="#{backing_collect2.activeSource}"
binding="#{backing_collect2.activeLayer}"
actionListener="#{backing_collect2.processClick}"
action="#{backing_collect2.collectAction}"
style="position:absolute;left:0px;top:0px"/>
</af:panelGroup>
// Code to get x and y from the request map
visit.setLastClickPoint(visit.getClickPoint());
FacesContext fc = FacesContext.getCurrentInstance();
String clientId = actionEvent.getComponent().getClientId(fc);
java.util.Map requestParams = fc.getExternalContext().getRequestParameterMap();
String xString =(String) requestParams.get((String)clientId + ".x");
String yString =(String) requestParams.get((String)clientId + ".y");
int xMouse = (new Integer(xString)).intValue();
int yMouse = (new Integer(yString)).intValue();Should have added that I'm using EA14

At runtime, can it be determined if multiple overlapping objects/layers exist beneath a mouse click?
Hi folks - total nube here. I am trying to find out whether I can determine if multiple objects exist beneath a usr's mouse click coordinates. The objects will be either shaded areas under a LineSeries in a chart or possibly overlayed images representing such areas (not sure which approach would be better). I know that I can probably determine alebraically whether the coordinates selected b a mouse click belong under one series or another or multiple and if this is the best option, then I will proceed with it. But possibly, there is a way for me to determine whether a shaded area under a series or a grpahical element exists under those coordinates. Any hints? Thanks in advance.
Yes, export it for your reference first. make it delete and create new one.
hope it should work fine.
thx

Mouse click point is not accurate
Has anyone ever had an issue with the mouse click coordinates not being accurate? For example, when I click on my canvas with the Rectangular Selection Tool, the point being clicked is actually 10 pixels below where the mouse is pointing! It causes much unnecessary headache...
Thanks for reading!How about giving some relevant information (see link)?

A script that captures the coordinates of the mouse clicks and saves them into a file
Hello,
I'm trying to create a cartoon taking a movie (I've chosen blade runner) as base. I've got the real movie and I've exported all the pictures using VirtualDUB. Now I have a lot of images to modify. I would like to modify the actors faces with the faces generated by Facegen modeller. I'm thinking how to make the whole process automatic because I have a lot of images to manage. I've chosen to use Automate BPA,because it seems the best for this matter. I'm a newbie,so this is my first attempt using Adobe Photoshop and Automate BPA. I wrote a little script. It takes a face generated with Facegen modeller and tries to put it above the original actors faces. But it doesn't work very good and I'm not really satisfied,because the process is not fully automated. To save some time I need to write a script that captures the coordinates of the mouse when I click over the faces and that saves them into a file,so that Automate BPA can read these coordinates from that file and can put the face generated with Facegen Modeller above the original face. I think that Automate BPA is not good for this matter. I think that two coordinates are enough,X and Y. They can be the coordinates of the nose,because it is always in the middle of every face. It is relevant to knows how big should be the layer of the new face,too. This is the Automate BPA code that I wrote :
<AMVARIABLE NAME="nome_foto" TYPE="TEXT"></AMVARIABLE>

and this is a short video to explain better what I want to do :
http://www.flickr.com/photos/26687972@N03/5331705934/
In the last scene of the video you will see the script asking to input the X and the Y coordinates of the nose. This request is time consuming. For this reason I want to write a script that captures automatically the coordinates of the mouse clicks. The only thing to do should be click over the nose and the script should make the rest. As "c.pfaffenbichler" suggested here : http://forums.adobe.com/thread/775219, I could explore 3 ways :
1) use the Color Sampler Tool’s input with a conventional Photoshop Script.
2) use After Effects would provide a better solution.
3) Photoshop’s Animation Panel might also offer some easier way as it might be possible to load two movies (or one movie and one image) and animate the one with the rendered head in relation to the other.
Since I'm a totally newbie in graphic and animation,could you help me to explore these ways ? Thanks for your cooperation.These are the coordinates of the contours of the face that you see on the picture. Can you explain to me how they are calculated ? The coordinates of the first colums are intuitive,but I'm not able to understand how are calculated the coordinates of the second one.
Thanks.

Using mouse click to return image coordinates.
Ok so I've been trying to figure out how to do this and it seems very complicated for something that really seems straightforward.
Anyway. I have a camera that updates an image object on the front panel using a while loop. I have another image object that is updated with a still image when the "snap" button is pressed. Now what I want to do is to click on a point in the snapped image and have the VI return the coordinates of that pixel in the image coordinate frame.
What I've got so far is an event structure in the while loop with the following to occur in the event "image object -> mouse down":
Server reference (reference to the image object) -> Property node (last mouse position) -> output screen coordinates.
I've got two errors that don't make a whole lot of sense to me (I haven't worked with event structures before): "event data node contains unwired or bad terminal" and "event structure one or more event cases have no events defined". This second one seems strange since I don't actually want anything to happen if there's no mouse click. The first one seems to refer to the element box on the left hand side of the event structure.
The above is my lastest attmpt at sorting this problem and as far as I can see it should work. whatever about the errors, am I even taking the right approach with this? I'd have thought image cordinates would be a common enough thing but search the boards here, it would appear not...
Kinda stumped here. Any help is much appreciated.

Solved!
Go to Solution.Hello RoBoTzRaWsUm,
I have taken a look at your VI, which has been taking a correct approach to the data you are looking for. As you are using and event structure, you should be looking for an event to occur. When using a Property Node, you are trying read an attribute of a control. However, in an Event Structure, I believe you should be using an Invoke Node. An Invoke Node allows your to read an event or write a method with the Control Class in LabVIEW.
1. Place down and Invoke Node from the Functions Palette in 'Programming'->'Application Control'
2. Wire your Image Control reference to it
3. Click Method, and select 'Get Last Event'
4. Right click on 'Which Events' and 'Create Constant'. Make the constant '1' in the array
5. Read the 'Coordinates' Cluster from the left hand side of the Event Case by right clicking and 'Create Indicator'
You will find a piece of example code attached.

Is it possible to generate a mouse click at specific coordinates on the stage?
Let's say x = 100 and y = 100. So, I have my main swf file that contains an external swf file with a button. Would it be possible to generate a mouse click on that button?
Any help would be greately appreciated.You don't do it that way - you'd just tell the button to dispatch a CLICK MouseEvent and anything listening for the click would get it... something like:
myButton.dispatchEvent(new Event(MouseEvent.CLICK)); -
How can I (neatly) control mouse click events in a multi-dimensional array?
Hello everyone!
I have a question regarding the use of mouse clicks events in a multi-dimensional array (or a "2D" array as we refer to them in Java and C++).
Background
I have an array of objects each with a corresponding mouse click event. Each object is stored at a location ranging from [0][0] to [5][8] (hence a 9 x 6 grid) and has the specific column and row number associated with it as well (i.e. tile [2][4] has a row number of 2 and a column number of 4, even though it is on the third row, fifth column). Upon each mouse click, the tile that is selected is stored in a temporary array. The array is cleared if a tile is clicked that does not share a column or row value equal to, minus or plus 1 with the currently targeted tile (i.e. clicking tile [1][1] will clear the array if there aren't any tiles stored that have the row/column number
[0][0], [0][1], [0][2],
[1][0], [1][1], [1][2],
[2][0], [2][1], [2][2]
or any contiguous column/row with another tile stored in the array, meaning that the newly clicked tile only needs to be sharing a border with one of the tiles in the temp array but not necessarily with the last tile stored).
Question
What is a clean, tidy way of programming this in AS3? Here are a couple portions of my code (although the mouse click event isn't finished/working correctly):
public function tileClick(e:MouseEvent):void
var tile:Object = e.currentTarget;
tileSelect.push(uint(tile.currentFrameLabel));
selectArr.push(tile);
if (tile.select.visible == false)
tile.select.visible = true;
else
tile.select.visible = false;
for (var i:uint = 0; i < selectArr.length; i++)
if ((tile.rowN == selectArr[i].rowN - 1) ||
(tile.rowN == selectArr[i].rowN) ||
(tile.rowN == selectArr[i].rowN + 1))
if ((tile.colN == selectArr[i].colN - 1) ||
(tile.colN == selectArr[i].colN) ||
(tile.colN == selectArr[i].colN + 1))
trace("jackpot!" + i);
else
for (var ii:uint = 0; ii < 1; ii++)
for (var iii:uint = 0; iii < selectArr.length; iii++)
selectArr[iii].select.visible = false;
selectArr = [];
trace("Err!");Andrei1,
So are you saying that if I, rather than assigning a uint to the column and row number for each tile, just assigned a string to each one in the form "#_#" then I could actually just assign the "adjacent" array directly to it instead of using a generic object to hold those values? In this case, my click event would simply check the indexes, one at a time, of all tiles currently stored in my "selectArr" array against the column/row string in the currently selected tile. Am I correct so far? If I am then let's say that "selectArr" is currently holding five tile coordinates (the user has clicked on five adjacent tiles thus far) and a sixth one is being evaluated now:
Current "selectArr" values:
1_0
1_1, 2_1, 3_1
2_2
New tile clicked:
1_0
1_1, 2_1, 3_1
2_2
2_3
Coordinate search:
1_-1
0_0, 1_0, 2_0, 3_0
0_1, 1_1, 2_1, 3_1, 4_1
1_2, 2_2, 3_2
2_3
Essentially what is happening here is that the new tile is checking all four coordinates/indexes belonging to each of the five tiles stored in the "selectArr" array as it tries to find a match for one of its own (which it does for the tile at coordinate 2_2). Thus the new tile at coordinate 2_3 would be marked as valid and added to the "selectArr" array as we wait for the next tile to be clicked and validated. Is this correct? -

How do I Get the value from a mouse click - on a waveform graph?
If I have made a plot into a Waveform Graph and later want to do a zoom of my data
(Not zoom into the Waveform Graph, but regenerate the data). How do I read the mouse
coordinate if I click on the graph window. I know how to put up the horiz and vert
cursors but don't know how to just read the mouse click. I would really like to
follow the windows standard that identifys a rectangle by clicking and draging and then
be able to read the corners of the rectangle. Thanks, Rick
PS: Using Labview 6iI would recommend to 'translate' your graph in a picture and dislay it in a picture control (see picture examples in LV6).
Once you did it, pictures have an extremely useful property called Mouse that returns the mouse coordinates and click events when you place the cursor on the picture.
By this you can re-arrange the graph on picture appearance.
There are also other methods such as using a Window's API that returns the mouse position referred to the whole screen window, but I believe this would be much more difficult to implement.
Let me know if this was clear and if you need an example vi.
Good luck,

Shifting of GUI Co-ordinate system when Mouse clicked
In my JDK 1.2.2 / Swing based application I have this problem of change in coordinate values (x,y) when a mouse click is used. This problem occurs sometimes and reason cannot be traced.
For e.g. If a user clicks "on" a Button the button is not affected , but the Button is pressed when the user clicks just "above" the button. When this problem arises it happens for all GUI components in the screen like textfield , combobox , table rows etc.
I hope the forum has answer / hint for this untraceable & intermittent problem.
Thanks in advance1) What OS are you using?
2) Did you try the app on a different machine?
- If yes, and it worked OK, make sure you have the newest video drivers installed on your system.
- If no, then beg/steal/borrow another machine to try it on, or:
3) (better still) post your entire code if it's not too big, or failing that, post a compilable/runnable subset of your code which shows the same behavior, so we can try it out. -
Hi, I have the following code so far, and when run in conjunction with other classes it creates a carousel feature.
When you click and hold on the carousel and drag up or down, the carousel moves in the relevant direction.
I am trying to change this click and drag, so instead when you click one of the polygons (which represent up and down arrows), the carousel moves up or down depending on which you click.
Can anyone help with this?!
Thanks very much!

Troubleshooting wireless mouse and keyboard issues -
Hi, id firstly like to begin by saying i am only learning Labview at the minute so i appeal for some patience,
I have done the relevant searchers also but i am unable to find an answer to my question.
Ok i am using a 17.5" resistive touchscreen to track the path of a ball which is placed on the screen..I want the screen to communicate the x-y co-ordinates to an x-y graph on the front panel of my program. In my attemp at doing this i have used a previous labview example which uses a mouse click event structure. However this means the touchscreen acts as a second mouse. My problem is that the touchscreen is not communicating with the graph directly as it is controlling the entire pc screen meaning it can interfere with the program.
I have included a two page word doc with screenshots which hopefully can explain better what i mean. One screen shot is the display result of the Labview program, the second resembels the path of the ball on the touch screen
Page one of the doc shows the ball tracking when only the first quadrant of the screen is used.
Page two of the doc shows the result when the full touchscreen is used. as the touch screen acts as a mouse it is only able to track the ball when it is in the same locating as the graph on the screen.
I have found it difficult to explain my problem but i hope you gurus can understand and provide me with a solution!
I am hoping someone can give me an answer that will allow the touchscreen to communicate with the labview x-y graph only.
Thanks in advance for any help.

As for your issue, there's a couple of things that are unclear from your description. Before offering a solution it's better to understand the objective here. The example you are using was specifically designed to only track mouse movements over the graph. However, your description seems to imply that you want to draw on the graph regardless of where the mouse is on the screen. Is this correct? If so, then you need to use the Input Device Control VIs to poll the position of the mouse, as that returns the mouse coordinates globally (search the examples for "mouse" and look at the "Basic Input Demo" example). Second, why an XY graph? Are you drawing a bouncing ball over some graphs? I would think you'd want to use the picture control. -
Mouse clicks on windows without focus
Is there a way to recognize when a user is clicking on a defocused JFrame, to bring it to the front, as opposed to clicking to set a text cursor position within the JFrame? For example, if I click on a terminal emulator I've developed, the text cursor within the emulation window goes to the click, even if the emulator is only being clicked to give it focus. (I've also noticed a similar phenomenon with JBuilder, by the way.)
By comparison, look at any native Windoze or Macintosh application; very few (if any) behave that way.This must be very hard for LabView to do. I just need to use LabView to run another application. Then have labview emulate a mouse click on that application. I have found out the windows message using Spy++ for the mouse click. Now in LabView I need to move the mouse to a certain position on that application. How could LabView know where to move the mouse cursor. I found some move cursor vi on this forum, then the coordinate of the position on the application (the active window) is not known. Do I need to map out the position in advance using Spy++? That seems not reasonable as later on the position may change.
LabView is indeed good for Hardware automation and data acquisition, but when it comes to performing some software automation tasks (i.e., runing a couple of other applications automatically), it doesn't seem to be powerful at all, unless the other applications are ActiveX capable, or you have their code to build Dlls. Most of time, one only need to automate the process of running a couple of other programs, then have data presented.
