We came across a very typical difference in the behavior of JFrame and JWindow.
We are maintaining a desktop application developed in java swing with one of the functionality to capture the screen. The application is a JFrame with various buttons added to it. The JFrame is set as setAlwaysOnTop(true). This screen capture works fine for all cases expect when OpenOffice presentation is running in slideshow mode on Ubuntu 8.04.
When the slideshow for presentation is activated, the presentation is coming on top of JFrame. Even though JFrame is declared as setAlwaysOnTop, it is not coming on top of slideshow. This is preventing the user from initiating the capture. This is happening only on Ubuntu (Linux Flavor). It works fine on Windows.
When we made a minor change (i.e. changed the JFrame to JWindow), it is staying always on top even when slideshow is activated.
Please go though the below example code. When the below code is run, the JFrame stays on top till a presentation is opened and slideshow activated. When slide show is running, it goes behind the slide show. If you change the JFrame to JWindow (shown in commented line), it is staying always on top even when slideshow is activated and we don’t even have the setAlwaysOnTop() property for JWindow.
Can anybody explain how can I make my JFrame to sit on top of PPT slide show as that of JWindow or any workaround to achieve this?
Sorry guys. Didn't know about the cross posting guidelines. Posted the question in sun and linux forums and waited for 2 days without any help. Since it's kinda urgent work, I've posted in other forums as well.
If someone has first hand experience of your problem, they would most likely post a solution, since it is from memory.
the rest of us would need to spend time writing demo code and testing to see if any theories worked.
now, given your cross-posts, it's unlikely anyone would invest their time in your problem.
you may have to pay someone e.g. rent-a-coder, with specific requirements of nullifying your problem
