i am facing a problem with event queue befavior..that is as follow..

suppose i have a JButton and i want to perform any operation on its mousePress and mouseRelease event.
i show a input dialog Box on mouse press and ask user for input. and then i want to use this entered value in mouse release. but as this dialog box comes into picture, the current thread dump untill we enter value in dialogBox and till then the rest of the events on queue flush out after performing their operation and so is with mouseRelease event that i want to use for any specific operation with entered value..
so this is the problem that mouse release fired before mousePress complete..

is there any way to overcome this problem?? plz suggest me any soln, workaround for it..

i am trying to alter my application's reqd behavior from these events but perhaps this is required.

I read your question twice, but I couldn't quite understand what your problem is, or what exactly you are trying to do. Are you trying to record the position of the mouse at the time of the click, or something like that?

Here's an idea that may help, or may just make more of a mess (in which case, you can exercise the full money-back guarantee). If you are opening a modal dialog in your event handler and that is somehow interfering with the flow you want, then maybe you could either start a thread, or fire a timer in your event handler instead. The thread or timer would then open the modal dialog at a slightly later time, allowing you to continue processing.

On the other hand, it may simply be a matter of doing whatever it is you wanted to do before opening the dialog box.
