### Apache NetBeans version Apache NetBeans 25 ### What happened A (non-editor) TopComponent with client property `TopComponent.PROP_CLOSING_DISABLED=true` is displayed with a tab with no _close_ button and no _close_ menu entry. This is OK. But actually it is still closable via mouse middle-click on the tab. ### Language / Project Type / NetBeans Component Netbeans platform application ### How to reproduce Add a TopComponent to a NB platform app. Add `putClientProperty(TopComponent.PROP_CLOSING_DISABLED, Boolean.TRUE); `in constructor. Run, middle-click tab name (possibly several times), TopComponent is closed. ### Did this work correctly in an earlier version? No / Don't know ### Operating System Win 11 ### JDK Adoptium 23 ### Apache NetBeans packaging Apache NetBeans binary zip ### Anything else It seems problem comes from: https://github.com/apache/netbeans/blob/master/platform/core.windows/src/org/netbeans/core/windows/view/ui/CloseButtonTabbedPane.java, see MouseListener at the beginning. I tried setting client property `TabbedPaneFactory.NO_CLOSE_BUTTON` to true in my TopComponent, so that `hideCloseButton()` returns true and blocks the call to `fireCloseRequest()` in `mouseReleased()`, but it did not work. I could not debug from my config so I stopped there. I found an easy workaround by overriding `TopComponent.canClose()` to return false. ### Are you willing to submit a pull request?
