GeoMap Mouse Coordinates to Longitude & Latitude

Is there a method on GeoMap to take the mouse coordinates generated by attachBrowserEvent('click', onClick) ev.getOffsetX(), into map coordinates (Lng & Lat)? I was hoping that the attachClick method would have provided an event with geo-coordinates, but attachClick doesn't seem to be working so I was advised to use attachBroswerEvent instead.

Flash player in firefox is not giving the exact mouse coordinates while running a flex application in firefox. Actually it was working fine in the previous versions. I mean in the ver 5.5. In the latest version its not working fine

Hi Friends,
I face some mouse issues with the later versions of the Firefox (6 and above). When a flex application is executed in a Firefox, It runs on the flash player in the browser. While getting the mouse coordinates, flash player is returning some bad coordinates. Please respond to this as soon as possible

About get mouse coordinates on screen?

how to get mouse coordinates in java, i don't look for a appropriate method.

The MouseEvent which is given to the MouseMotionListener or the MouseListener has one getX() and one getY() method. That are the coordinates in your applicetion window starting with (0,0) in the upper left corner.
Hope this helps

Mouse Coordinate issues caused by Scaling Components in a JScrollPane

Hi All,
I've been attempting to write a program that includes a simple modeler. However, I've been having some trouble with being able to select components when attempting to implement zoom functionality - when I "zoom" (which is done via scroll wheel) using the scale Graphics2D method, while it zooms correctly, the mouse location of components do not seem scale.
I've tried one of the solutions found on the forums here (create a custom event queue that adjusts the mouse coordinates) and while it seemed to work initially, if I zoom in and adjust the current view position using the scrollbars, certain components contained in the JPane will become un-selectable and I haven't been able to work out why.
I've attached a SSCCE that reproduces the problem below - it implements a JScrollPane with a JPane with a few selectable shapes set as the Viewport. The zoom is done using the mouse scroll wheel (with wheel up being zoom in and wheel down being zoom out)
Any help in order to fix the selection/de-selection issues on zoom would be greatly appreciated! I've spent some time reading through the forums here but have unfortunately not been able to find a workable solution around it.

Delete your EventQueue class. Change one line of code in your mouse pressed method.
public void mousePressed(MouseEvent me) {
    Component c1 = findComponentAt((int) (me.getX()/getZoom()),
                                   (int) (me.getY()/getZoom()));

GIS question: visualisation of locations based on longitude/latitude

Hi,
First of all: I'm a total beginner for everything related to GIS. I'm a bit lost at where to start, so any hints are welcome.
I have a table with a number of locations, for each location I have values for the longitude and latitude (Oracle format).
Would it be able to visualize these locations on a map using Oracle Locator, MapViewer or Google Earth ? I'm using Oracle 10g with patch set 10.2.0.4.
Thanks,
Matthias

Oracle Database are having through Oracle Locator support for spatial data storage via its datatype sdo_geometry.
A good place to start is the user documentation:
http://download.oracle.com/docs/html/B14255_01/toc.htm
In your particular case your Longitude latitude columns could be use as follows:
Add a column GEOMETRY of datatype sdo_geometry to your table
UPdate that via:
update YOUR_TABLE a
set geometry=
sdo_geometry(
2001, ---2D point
8307, --- SRID (assuming WGS84 for your lon/lat)
sdo_point_type(a.longitude, b.latitude, null), ---specific point notation
null,
null);
create an entry in the user_sdo_geom_metadata (see user manual)
create an index (see user manual)
Once you have these in place, you can start looking to some solutions as you mentioned or as described by Ivan to use this data to be visualised.
Hoping this gives you a an idea where and how to start

In Photoshop CS6 how do I turn off the move tool popup showing the mouse coordinates?

I just installed Creative Suite CS6 and in Photoshop, when I use the move tool a small popup window shows the mouse coordinates. I can't see any option to turn this off, either in the Options bar or the Preferences. It's really annoying. Can someone please help?

Plotting on xy graph based on mouse coordinates

I am looking into plotting Mouse coordinates on XY Graph continuously based on where i move. My computer's resolution is 1200x800 and i would like it to plot based on where i move.,
Attached is my progress so far.

The XY Graph has a method which converts coordinates to XY values. You can call it by right clicking the graph and selecting Create>>Invoke Node>>Map Coordinates to XY.
However, if you look at the help for it, you will see that the coordinates it expects are those of the pane the graph is in, and the coordinates you have are of the screen. You can convert your global coords to pane coords by getting the VI's Front Panel Window. Panel Bounds property, building two matching XY clusters from the data and subtracting them (assuming the VI only has one pane) or you can use another loop with an event structure and a Mouse Move event (which returns local data) on the graph and then transfer the position data to your loop (you could also use a single loop, but that might be more complicated because the event structure will process every move of the mouse as a new event).
You will also need to keep the data to place in the graph somewhere. If you open the context help window and hover over the graph's BD terminal, you will see the data types it expects and you will need to build one of those yourself. A shift register is something you might want to look into. There are also some examples showing working with graphs in the example finder (Help>>Find Examples).

Mouse Coordinates and Timer Resolution

First - I am not a Flash or ActionScript programmer. I have
been asked by someone if I could port my ActiveX code (private) to
the Flash client. In researching all of the Flash, Flex and
ActionScript documentation, it appears that almost everything I
need is present... Almost....
A. My program relies on Mouse Coordinates being fed to it in
twips. The only possible references I get to this issue have come
from searching this forum.
- Is it true that the X and Y coordinates are returned to
ActionScript as floating point values that represent fractional
pixel values that I can translate to twips?
B. My program also relies on good timer resolution. The
Windows GetTicks() API is not sufficient, because it is returned
via the Windows message queue and can be off enormously at a
MouseMove event. Therefore, in my ActiveX code, I call the
QueryPerformanceCounter(), which gives me the resolution I need.
- Can anyone tell me what timer API the Flash client engine
is using for the values it returns?
Thank you,
Grant

I still don't understand your problem and apparently nobody else does either since there are no responses. Why don't you write a simple program (like I did for you on your last post) that demonstrates the problem.

Geocoding Longitude Latitude Java API(s)

Hello,
I only need to get the longitude and latitude (no maps no nothing else) for a given address. The problem I am having is that I have about 12000 stored addresses and would like to get their corresponding longitudes and latitudes. But the free services offered by some websites allow you to retrieve only one at the time so it is time consuming.
Does anyone know about either a trial version or some Java API(s) -so I can write my own program- to retrieve the longitude/latitude of an address?
Thank you very much.

This is not quite the answer, but I it is close and free of charge:
I saw this page:
http://www.personal.psu.edu/users/m/j/mjl284/proj6.htm
I have looked into this, so go to
http://www.esri.com/software/arcexplorer/index.html
launch ARCExplorer
Push add service and add the ESRI "Service", then add Census_TIGER2000
Use Binoculars button to type in a street address in the area of interest.
Zoom in and push the Identify "i" button. Click on a street.
A window will come up with a bunch of yucky field names and values.
Those numbers are the key. Especially note the numbers for the state and county.
Now, go to the Tiger2000 web site. For instance, for California:
http://www2.census.gov/geo/tiger/tiger2002/CA/
Get the county data, for instance for Santa Clara,
http://www2.census.gov/geo/tiger/tiger2002/CA/tgr06085.zip (about 5MB when zipped)
Unpack the data files, which are text, and go back to the Indentify window with all the codes
The other numbers are indices. In particular, TLID.
The TLID for my 1/10 section of my street where my building is is 122955605
Now, I already know that my geocode is approximately: Lat 37.391 Long. -122.068
My address is 67 E. Evelyn Ave.
Here is that line in those files:
file: TGR06085.RT1, line 32046:
11102 122955609 AE Evelyn Ave A41 100 198
101 19900009404194041 06060850859283092830
496704967050910950910910111013-122066172+37390040-122063872+37389240
and now I see in in this data.
The FNODE 6558, TNODE 6755 from the window mean that, I think, it goes from-node street address 65 to-node street address 67.
You can go read the Census web pages for docs on the other fields.

If it is on...then try a hard reset...Hold both Sleep and Home buttons at same time for about 10-15 seconds until you see the white Apple symbol...then release...
Lastly, are you outside when this issue is seen...since GPS location first needs location services to be on then it needs a sat signal...being inside may be causing it not to show up

Mouse coordinates on the screen

is it possible to get mouse coordinates on the screen? i want to make a program which makes screenshots of areas on the screen and i want use the mouse to mark them.
how could i do that? is it possible to get mousecoordinates even if the mouse is outside the java JFrame?
there must be a way! i searched in the forum but i found no answer.
please don't tell me i have to use jni, the app should be platform independent.

Yeah, basically there's no way to do this. This should be requested if it hasn't already (too lazy to check). It's not hard for sun to add, they just need to add it. Ok, anyway, I looked into it and see if there was a way to do this even somewhat reasonably in Java. I was very disappointed. I pretty much had no luck, but I did get a lame way of implementing this :P After some thought, this is what I ended up with:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class MousePosition extends JFrame implements MouseMotionListener
    private int x = 0;
    private int y = 0;
    private boolean isAP = true;
    public MousePosition()
        setSize(300, 300);
        setLocation(200, 200);
        addMouseMotionListener(this);
        addMouseListener(new MouseAdapter()
            public void mousePressed(MouseEvent e)
                isAP = false;
        setVisible(true);
        try
            Robot r = new Robot();
            r.mouseMove(getLocation().x + 50, getLocation().y + 50);
            r.mousePress(InputEvent.BUTTON1_MASK);
        } catch(AWTException e) {}
    public void mouseDragged(MouseEvent e)
        System.out.println(e.getX() + getLocation().x + ", " + (e.getY() + getLocation().y));
    public void mouseMoved(MouseEvent e) {}
    public static void main(String[] args)
        new MousePosition();
}So it'll "lock" the program getting the absolute coordinates until you press the mouse, then you're free to do what you want. You could also do this with keyPressed or anything else you want. JNI would be the real solution as of now, until then I think sun should address the problem.

Mouse coordinates.

I want to make an applet (dimensions cca 50x100).
But I want it to display the mouse coordinates, no matter where the cursor is (over the applet or elsewhere on the desktop).
Can you give me some ideas? What classes to use, some approaches to my problem etc.
Advanced thanks (like this forum is).
iulian

I think your only way out of this would be to use JNI. On Windows you can then use thr MouseCapture functions (or a hook function) to get mouse messages wherever the mouse is, but of course that is platform specific. Otherwise, the JVM will only get mouse messages when the mouse is over the Java window(s)

tahnk u very much :)

sorry for not using the code tags..just learn about it...thanx
my problem is.when i want to record every coordinates of the mouse while it moves..but using the printstream,it only records the end point of the mouse and not while the mouse moves/dragged.I'm developing a sketch pad program. the program needs to capture the coordinates and saved it into a file.i tried using it but keeps on saving the last point but not all
example
point A..........................point N............................point Z
i want the program to save the coordinate of point A,point B,C,D...point N....and last point Z
but it keeps on saving only point Z.can u help or give any ideas..thanx

How to find out the mouse Coordinates

How can I find out the mouse coordinates, where I am clicking on the screen.
I tried to use MouseEvent e, e.getX() and e.getY() but it is giving that particular components X,Y coordinates

In SwingUtilities there is a method called that can be used to convert a local location to a screen location.
public static void convertPointToScreen(Point p,
Component c)
Convert a point from a component's coordinate system to screen coordinates.
Parameters:
p - a Point object (converted to the new coordinate system)
c - a Component object
