Why robot class doesnt get cursor
i am using robot class , when i use createScreenCapture
method it gets the everything on the screen but not the cursor.
why? can i create i image that also get the cursor?
many thanks
MouseEvent provides a method:
public Point getPoint()
that returns the x,y position of the event relative to the source component.
I guess it must be the archiect's view that the cursor is not a the screen, rather a device that points to the screen.

Robot class and positioning the cursor
I have an application where I have a number of panels on the screen and using an editable field wish to enter coordinates to position the Cursor to on another panel.
ie, using grid coordinates on a map. Using the robot class I am able to position the cursor on the other panel but as soon as I move the mouse the cursor jumps back to the original position on the screen where the first panel with the editable field was. It is like only a picture of the cursor was drawn at the new coordinates and the real cursor is still at the old podition. It is important to this application that if the cursor is moved it stays where it has been moved to and actually is there and not just appearing to be there. I am using jdk 1.3 on Intel Solaris 2.8. Any help on this issue would be helpful and appreciatedMaybe you can use the mouse move event to position the mouse to where you had moved the cursor to.
for example
1.the mouse is at point 100,100
2. you move the cursor from your code to point 0,0
3. the user starts to move the mouse
4. you code gets that event and repositions the cursor to the last place where it was, that is at 0,0 -
Why do I still get class or interface expected error????
I made sure I closed all the bracket, why do i still get the error.
Please help

I got 72 errors when I tried to compile the code you posted. Many of them are due to syntax errors like { and } not lining up. -
why do i keep getting a multi-colored circle in place of the cursor right before the browser shuts down on me??

Hi all!
How can I get the field where the cursor is placed in a component?
Thanks in advance!!!Hi.
using html tag you can trigger the "OnMouseOver" event.
Here you are an example:
1) An input field:
< input type="text" name="name" on_mouseover="ACTION" />
where "ACTION" could be a javascript or a bsp standard event, and
on_mouseover must be replaced with onmouseover (i don't know why but sdn doesnt' let me include the right statement).
Hope this will be helpfull.

Doing Shift-End using Robot class
I am trying to use the Robot class to do a Shift-End in order to select the text in a window from the cursor to the end of the line. However, the following code only moves the cursor to the end of the line without selecting the text.
robot.keyPress(KeyEvent.VK_SHIFT);
robot.keyPress(KeyEvent.VK_END);
robot.keyRelease(KeyEvent.VK_END);
robot.keyRelease(KeyEvent.VK_SHIFT);
Note that I have been able to make the following code work. So the problem with the code above does not seem to be with the Shift key per se or with the ordering of the statements.
robot.keyPress(KeyEvent.VK_SHIFT);
robot.keyPress(KeyEvent.VK_A);
robot.keyRelease(KeyEvent.VK_A);
robot.keyRelease(KeyEvent.VK_SHIFT);
Any idea how to make the Shift-End work? I am using an XP PC.My ENTIRE code follows. Not surprisingly, the shiftEnd.actionPerformed gets a nullPointerException during execution. And being new to Java, I get the feeling I might be missing a whole bunch of stuff. For example, do I need to register for events? Do I need to generate a shift-End ActionEvent somehow? It is only the last 4 lines that are at issue here. Everything down to that point accomplishes what I want, i.e., position the mouse in a text window in the upper right-hand corner of my screen, move the cursor to the top of that window, then go down 5 lines. At that point, I want to do the shift-End to select all text in the line.

I am using the robot class to make a macro that moves and clicks the mouse for a few hours. At first, the macro works correctly, and completes about five runs per second. However, after a few minutes the macro starts slowing down, and after an hour it is running through once every 10 seconds. Every run is exactly the same, so why could it be slowing down?
Here's exactly what it's doing:
1. get the color of the next pixel in a BufferedImage.
2. make a robot and have it type the RGB values of the pixel into another window.
3. move the mouse and click it a few times.
I'm not using the hard drive. I'm not searching anything. I am not copying anything. Every run is exactly the same. Why is it getting slower as it runs? It finishes about a quarter of the image in 5 minutes, then hours later it has only done a few more rows. -
Regarding sy-lilli, Get cursor line
Hi Folks,
I'm having some trouble with getting the cursor line in a search help selection.
This is my code:
CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

retfield = 'XBLNR'
dynpprog = sy-repid
dynpnr = sy-dynnr
dynprofield = 'ITAB-FACTURA'

value_tab = itab_bsik_v[]
return_tab = return_tab
EXCEPTIONS
parameter_error = 1
no_values_found = 2
OTHERS = 3.
IF sy-subrc = 0.
ENDIF.
GET CURSOR LINE l_linea.
READ TABLE itab_bsik_v INDEX l_linea.
DATA: l_stepl LIKE sy-stepl,
l_indx LIKE sy-stepl.

l_indx = grid-top_line + l_stepl - 1.
REFRESH dynpfields.
CLEAR dynpfields.

dynpfields-fieldvalue = itab_bsik_v-xblnr.
dynpfields-stepl = l_stepl.

EXCEPTIONS
OTHERS = 0.
The internal table itab_bsik_v is filled with 10 records. So when user clicks on record 5, I would expect that l_linea gets 5 as cursor line, however I'm getting 1 always.
I tried changing the GET CURSOR LINE by sy-lilli but I'm not understanding really well the sy-lilli variable because when I click the first line of the search help result, I get a 4 as the index, and when I click in the last line I get 13.
If anyone could help me with this I really appreciate it.
Thanks for your help.

Hello,
It seems like there are problems with the java Robot class in Windows Vista.
Did anyone encounter them?
ThanksI didn't get your response, but I will try to explain myself.
I have a problem with a program that I wrote that uses the Robot class and doesn't run well on Vista.
I think that the operation system isn't letting it to control the mouse/keyboard: The program didn't crash,
Simply didn't move the mouse although it was supposed to.
I searched google for relevant information and the only relevant result I found was the link I posted.
That link doesn't help me because in order to view the answer I have to pay money.
I posted it because I thought that another description of the problem might help to understand it. -
Taking screenshot with java applet using java robot class not working
Hi Everyone,
I am using the java applet to take screenshot of the web browser using the java's robot class.
Robot objRobot = new Robot ();
BufferedImage objBufferedImage = objRobot.createScreenCapture(objRectArea);
The thing work good in windows system taking screenshot but in case of mac osx i get the blank image.When i check the event viewer in mac osx i get the following error.
invalid context
invalid pixel format
CoreAnimation: rendering error 506
The problem is coming for all the browser safari,firefox and chrome.My applet is signed applet.
What might be the reason.An early reply is very valuable.
My machine configuration is as follows.
OS : MAC OSX
Version : 10.6.4
Is that a system level issue , java plugin issue?I'am confused with this error.
Thanks sagar.870613 wrote:

I need to make a macro with the robot class that draws a picture in a paint program. For each color in the image (256 colors total) it should change the paint color and drawing each 2x2 pixel that's that color. I made the program and it works correctly for about an hour, but then it starts slowing down a LOT, entering the wrong color codes, and drawing single pixels instead of 2x2.
Here is the code for changing the color:
robot.mouseMove (535, 504);
robot.mousePress (InputEvent.BUTTON1_MASK);
robot.mouseRelease (InputEvent.BUTTON1_MASK);
robot.mouseMove (568, 410);
robot.mousePress (InputEvent.BUTTON1_MASK);
robot.mouseRelease (InputEvent.BUTTON1_MASK);
robot.mousePress (InputEvent.BUTTON1_MASK);
robot.mouseRelease (InputEvent.BUTTON1_MASK);
for (i = 0; i < 6; i++)
robot.keyPress (color.toUpperCase ().charAt (i));
robot.keyPress (KeyEvent.VK_ENTER);
robot.keyRelease (KeyEvent.VK_ENTER);Here is the code for drawing each pixel:
robot.mouseMove (415 + (w * 2), 185 + (h * 2) - 1);
robot.mousePress (InputEvent.BUTTON1_MASK);
robot.mouseMove (415 + (w * 2), 185 + (h * 2) + 1);
robot.delay (100);
robot.mouseRelease (InputEvent.BUTTON1_MASK);Does anyone know why the robot stops working after about an hour?I'll guess that this might have something to do with it:
for (i = 0; i < 6; i++)
robot.keyPress (color.toUpperCase ().charAt (i));
//need to release the key!
robot.keyRelease (color.toUpperCase ().charAt (i));
}Also, about your code to draw one pixel: it draws three pixels in a vertical line, at least in my paint program. -
I am using the Robot class in jdk1.3.1 to record and playback user input. I am getting the list of events and then traversing on it to do the appropriate action, mouse move, key events are played back fine, but I am unable to do mouse drag event.
Here is simplified version of the code:
for(int i = 0; i < aListEvents.size(); i++)
AWTEvent event = (AWTEvent)aListEvents.get(i);
Component c = (Component)event.getSource();
int id = event.getID();
switch(id)
case MouseEvent.MOUSE_MOVED:
int x = ((MouseEvent)e).getX();
int y = ((MouseEvent)e).getY();
m_robot.mouseMove(x,y);
break;
case KeyEvent.KEY_PRESSED:
m_robot.keyPress(((KeyEvent)e).getKeyCode());
break;
case MouseEvent.MOUSE_DRAGGED:
// do component drag
break;
Is there a way to mimic the drag event during playback and drag the object that was dragged during record?
Any suggestions would be greatly appreciated!!
Thanks :)This is an old posting, so the answer is probably too late for mamta and has also been answered elsewhere. But for whoever comes across this one, share my piece of experience:
There's no one-to-one mapping between Java events and the system events (which is what Robot is refering to).
After all, a MOUSE_DRAGGED is nothing but a MOUSE_MOVE after a MOUSE_PRESSED. So you can send a MOUSE_DRAGGED along to the robot as a mouseMove, because the Robot/system keeps in mind that the mouse button has been pressed before and therefor the event will appear in the Java event queue as a MOUSE_DRAGGED.
Similar is MOUSE_CLICKED which needn't be replayed at all, because sending a MOUSE_PRESSED and a MOUSE_RELEASED to the Robot will automatically produce a MOUSE_CLICKED in the Java event queue as well.
Same with the key strokes. -
Why this path doesnt work when there is "!DOCTYPE" element?
Hi, I need to extract contents from an xml file, which looks like
<hr />
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE article PUBLIC "-//ES//DTD journal article DTD version 5.0.1//EN//XML" "xyz501.dtd" > <!-- LINE 1 -->
<article docsubtype="fla">
<item-info>
<jid>YANBE</jid>
<aid>12941</aid>
</item-info>
</article>
<hr />
And I have tested with this path "//article/item-info/jid/text()", but it doesnt give me anything. But I noticed that when I remove line 1, it does extract the content "YANBE"...
why the path doesnt work when there is that DOCYTYPE element? How should I get around with this please?
Many thanks!The extract of XML you gave is not valid (Line 1: <hr/>) but besides that ... I think your problem is in the DTD.
Somewhere in the DTD it probably 'sneakily' defines a default attribute which in reality is a default-namespace for one of the elements. This means that in your XPath handling, you will have to map a prefix to a namespace-uri (NamespaceContext [1]) and use this newly defined prefix in your XPath expression.
//tst:article/tst:item-info/tst:jid/text()[1] http://java.sun.com/j2se/1.5.0/docs/api/javax/xml/namespace/NamespaceContext.html
