TopComponent Opacity

Geertjan Wielenga

In the constructor of a TopComponent, add this:


Then, if that doesn't work, it means that the parent of the
TopComponent also needs to have opacity set to false. So override
the "addNotify" method of the TopComponent. In that override, include this:
JComponent parent = (JComponent)getParent();

    Would you please visit following link to answer my question related to NetBeans?

    No, I won't. Please post your questions at dev@platform.netbeans.org, that's where I (and most other people) answer NetBeans Platform questions. Make sure the question is about the NetBeans Platform, otherwise write to nbusers@netbeans.org.

    Problem - Controlling the location of TopComponent.

    We are a software company and we implement Netbeans RCP Applications. We love it. Only problem we had was to control the location of the TopComponent. We create a Custom Top Component with mode as "rightHandSide" sliding window. It appears on the right hand side only the first time. When you close and open it appears on the left. Also, if you reset windows, it appears on the left again. This has been the only problem. Can you help us how to control the position ?
