Thanks Neil, inspired by that I created a small example and stepped it back all the way to RELEASE90. My problem occured all the way, so no recent regression involved in my issue.
Digging a bit further though I realised my problem stemmed from lack of window focus (and maybe some other yet to be confirmed situations) when displaying dialogs. In combination with DropTargetDropEvent that is. So, a multi monitor setup is not the cause of the problem. Depending on how a file is dragged and dropped from other applications, this problem occurs, or not. On Windows it's possible to drag a file from Explorer without Explorer gaining focus, getting activated. Knowing that, I solved it with the following code in my Drop listener: SwingUtilities.invokeLater(() -> { SwingUtilities.getWindowAncestor(MapTopComponent.this).requestFocus(); SwingUtilities.invokeLater(() -> { //Display the dialog }); }); But, back on linux, the problem was still there. It was because of the focus stealing prevention setting of KDE Plasma's kwin. For good or bad, I resorted to the sledge hammer awt.Robot and created public static void requestWindowFocusAndRun(Component c, Runnable r) https://github.com/trixon/almond/blob/7c22ec5888557ff1afc991e701c84a8f212fe526/util/src/main/java/se/trixon/almond/util/swing/SwingHelper.java#L248 Unless it's possible to add a notify(descriptor, parent) to DialogDisplayer I don't think of this as a NetBeans problem but perhaps NB can provide a good solution, or better yet, it might be solved in swing/awt. /Patrik Den ons 20 apr. 2022 kl 10:43 skrev Neil C Smith <neilcsm...@apache.org>: > On Tue, 19 Apr 2022 at 08:04, Patrik Karlström <pat...@trixon.se> wrote: > > > > I'm trying to find a way to improve my platform applications' handling > of dialogs. > > Developed on a laptop, I was not aware that dialogs did not follow the > main window, instead they are displayed on the main screen. > > > > I use descriptors and display them with > > DialogDisplayer.getDefault().notify(d) > > > > And I can't find a way to specify the dialog parent with that approach. > > I did find createDialog(DialogDescriptor descriptor, Frame parent) but > I'm not really sure what I should do with the returned dialog since I want > an easy way to get the clicked button, if any. > > > > What is the best way to create and manage dialog wrt parents in a > platform app? > > IIRC the default implementation is in core.windows.
