How to set focus to s specific image in a plugin

Lambacher, Armin

Hello Everybody,

I do some evaluations on an image and upon certain keypresses a result is added to a ResultsTable. After that I want to get the focus back to the original image again. I tried to understand the logics of the WindowManager, but it seems that I fail in that respect.

Here’s a code snippet, the whole code is to big to attach. The function “_createBleachingResult()” will add the current result to the ResultsTable (creating the ResultsTable upon first call). After adding the result I call the show() function of the table to update the screen representation. Then I try to get the focus back to the _sourceImage. When debugging, the content of win seems resonable, as the debugger shows the correct title of the _sourceImage in the win variable. But neither “setCurrentWindow” nor “setWindow” bring the focus back to the _sourceImage.



                _createBleachingResult(bd);
               
                if( _bleachingResultsTable != null )  
                {
                        _bleachingResultsTable.show("Bleachings");
                }
               
                // after bleaching is added, we try to set focus to the image again
               
                ImageWindow win = ij.WindowManager.getImage(_sourceImage.getTitle()).getWindow();

                IJ.wait(100);
               
                ij.WindowManager.setCurrentWindow(win);

                ij.WindowManager.setWindow(ij.WindowManager.getWindow(_sourceImage.getTitle()));




Can anybody please enlighten me?

Best

Armin

Hi Armin,
Selecting image windows by title isn't safe, as you might have several
images with the same title. Selecting by image id is better as each image
has a unique id.

In short, you can get an image id with:

  int id = imp.getID();

and later select it with:

  IJ.selectWindow(id);

Sincerely,
Jerome
