Now that this has proven to be potentially problematic, I'm looking for other ways to block input to a Swing GUI for a set amount of time. The reason I want to do this is to disable the user from manipulating any GUI controls for a second or so while a task that uses them completes, and if it takes longer, pop up a modal progress monitor. More details are given in the topic above.
One solution would to do mass disabling of all GUI components, but this provides a visual effect that can be problematic for several reasons as discussed in the topic above. Another suggestion was to use the glass pane to consume mouse input events, but accelerators, mnemonics and similar still seem to work, and maintaining dialogs can become problematic.
I don't understand why you have started a new thread. Nothing in what you have posted make the use of glass panes 'problematic' ! You just need a glass pane for each dialog and a method of timing how long the operation has taken.
What about accelerators and mnemonics? In my tests, they can't seem to be caught by a glass pane. Thanks for the Spin link, I'll have a look at that. Meanwhile, if anyone knows a good way already, do tell!
