Hi,
This may be a reach as this is what we call in the Notes/Domino world as an Agent. However, it is a Java agent and the agent works outside of Notes. So, I am hoping that someone out there may have an idea as to what is going on. Anyway, from my Notes client (for those of you who have never used Notes, it is a sophisticated gui program that runs on Windows), I am launching an agent that basically creates an invisible frame. From there, I create a dialog box (awt, not swing). The dialog box has a list component, a label and a couple of buttons. The dialog box comes up, but I can't do anything in the dialog box until I minimize and maximize a window from another application. I can't select from the list, I can't click a button, and I can't move the dialog box.
Does anyone have any ideas what is going on here? I am new to Java. Is it an event queue problem? How can I force my dialog box to get focus? I have tried requestFocus() for the dialog box itself as well as a particular component.
Again, this works outside of Notes just fine, so I realize that is the culprit, I just don't know enough Java to understand what is going on and how to grab focus.
Here is the code. Ignore the Notes specific stuff. You can go right to where I create the frame:
Thank you so much,
