Does anybody know if this could be done within IJ?

If the plugin runs in a different thread, can one write a plugin that the only
thing it does is to locate the grabbing plugin window and emulate one click
on the necessary button?

Can anybody suggest a way of doing this?

Cheers,

Gabriel

Thanks Wayne, this is exactly what I was looking for.

I thought it would be also nice to make it able to send key presses too, but I
am struggling with the last bit:  how to convert a string into KeyCode...

If 'robotText' is a string that holds the text that the robot is suppossed to
send/type, the following does not output what I expected.

for (int i=0;i<robotText.length();i++){
        robot.keyPress( robotText.charAt(i));
        robot.keyRelease(robotText.charAt(i));
}

For instance if the string is "ABC-abc" the robot types:
"abc-123". I am obviously doing something wrong.

Any idea how to convert the char to KeyCode? (is the KeyCode what I need?).
Or do I have to make a table to parse the chars into KeyCodes?

Thanks in advance,

Gabriel

I have not tested it, but this snippet could work:

-- snip --
import java.awt.event.KeyEvent;

[...]

String toSend = "ABC-abc";
KeyEvent e = new KeyEvent(null,
for (int i = 0; i < toSend.length(); i++) {
        char c = toSend.charAt(i);
        e.setKeyChar(c);
        int keyCode = e.getKeyCode();
        robot.keyPress(keyCode);
        robot.keyRelease(keyCode);
}
-- snap --

Hope this helps!

Gabriel,

Yes you can have a plugin running on its own thread that never returns (never
ends), and either use the Robot class to make clicks (your mouse pointer will
move too, which is undesirable), or directly execute the button -just capture
it by exploring down the Container classes. For example, from the WindowManager
get the window of the video, then lists its components, then for each one that
is a container (JPanel, etc) list its components, et cetera until you find the
button. Then "doClick()" on the button (if it's a JButton). It all may be
easier by creating a MouseEvent with the button as the object and passing it to
whatever object is the MouseListener (this is what java does internally
anyway).

Hope it helps.

Albert

Thanks, yes I am trying via the Robot class.

I will have a look at this. I think that the image capture plugin is just a
wrapper of their image capture which I guess it is written in C or C++ (it
looks the same, although some functions are greyed out), so that may not
work.
Anyway, I will post the robot when it is finished because I think it could be
quite handy.

Thanks again,

Gabriel
