I want to get the node in a GridPane by index, I know you can do this by iterating through getChildren, but I was wondering if there was a less ugly way to do it. If I knew getChildren was sorted, it could be done by
getChildren.get( row*width + column)
getChildren() simply returns a reference to a
List. The order of the elements in that list is determined entirely by the methods you call on it and the order you call them. E.g. calling
add(child) will add an element (a
Node) to the end of the list, so if all you do is call
add repeatedly, the nodes will be arranged in the list in the order you add them. If you call
add(index, child) the child node will be added at the specified index (so if you repeatedly call
add(0, child) the child nodes will be in the reverse of the order in which you add them. If you call
addAll(nodes) the child nodes will be added in the order they appear to the end of the list, etc.
So the bottom line is that you can control the order of the child nodes in the list to be whatever you want it to be.
