The application needs to open image files specified on the command line, then display on top of those images the information read from any additional "overlay" files specified on the command line with a named argument "--overlay".
Some of this is working as intended. The DataLoader finds the image DataObjects and successfully opens the files in the appropriate editor. Then, with a CommandLineProcessor class
@ServiceProvider(service=OptionProcessor.class)
publicclassCommandLineProcessorextendsOptionProcessor{
...
}
the additional "--overlay" files are parsed from the command line
successfully.
The overlay files get read, but alas, their contents never get overlayed on the images. When the overlay file's DataObjects's method gets called to read their content, it cannot find the TopComponent for the associated image file on which the information should be displayed.
Its search through all opened TopComponents, using WindowManager.getDefault().getRegistry().getOpened(), finds other TopComponents (such as Notifications, Project, and maybe some others), but not TopComponents for the just-opened image files.
Suspecting that the overlaying is happening before the image TopComponents get registered, I use WindowManager.getDefault().invokeWhenUIReady(...) to defer the overlaying until after all the image files are opened and the UI has stabilized. Alas, this doesn't suffice.
What could be wrong here? Is there a way defer the overlay processing until after all the image TopComponents get registered (assuming that's the problem)?
