I have a GridPane for which I change the row/column arrangement when the window resizes. If GridPane components had attached properties for their grid coordinates, I'd just change the properties. But instead I guess I have to clear the pane and lay it out afresh, building it up row by row (which, may I say, is a little bit tedious in comparison to the WPF approach to containers). I have all the components already pre-built and stored in a master list, so I thought I could just do
pane.clear(); doMyGridLayout(pane, components); However, when I do that, I get an exception in GridPane$Row.insert: "Component already has a parent." So instead of calling clear, I have to do something like this: RowSequence gridRows = pane.getRows(); gridRows.remove(0, gridRows.getLength()); as, apparently, RowSequence does know how to unparent its children (not that this is so painful -- I initially feared I'd have to remove my components one by one). Am I missing something, or did GridPane forget to override clear() and do something reasonable? (I haven't tried it, but I'm wondering if the same question could be asked of TablePane.)
