macro listening to thread

[Jan Eglinger-5]

Dear all,

is there a way to tell a Macro to wait until a plugin running threads
has finished?
I'd like to wait until the output window of the plugin
(ExtendedDepthOfField in this case) appears, and then continue the macro
without the need of any user input.
Is this possible in a macro, or do I have to use a plugin for this?

thx for any hints,
jan

A quick and dirty way:

        x = getImageID();
        run("ExtendedDepthOfField ", "arguments to the plugin");
        while (x == getImageID())
                wait(100);

This just waits (sleeping 100 milliseconds at a time) until the current
image is different.

Hi,

thanks for the suggestion, I tried it like this and also with
getTitle(), but:

the while loop doesn't stop after the new Image appears. I can see the
image window, but the macro apparently still gets the old ImageID and Title.
Any idea why?

Is there a way to check in a macro if an image with a given title exists
in the window list?

best,
jan

(using ImageJ 1.38f)

Evidently, the current image is not changed. Could you try with
"nImages()" instead of "getImageID()"?

Try "isOpen("Title")".

Look for isOpen() function.

I hope it helps.

Both the getImageID() and getTitle() macro functions have bugs that
cause them to not notice when an image window is opened by a plugin.
These bugs will be fixed in ImageJ 1.38g. In the meantime, you can work
around the bugs by using the nImages() function.
