I can’t seem to get the setAlignment method to work to center my HBox of buttons, labels, and textFields. Everything I’ve read online makes me think I’m doing everything right but I think I’m missing something because this isn’t working.

This is the section I’m having problems with.

        HBox edgeBox = new HBox();

        edgeBox.getChildren().addAll(addEdge);
        edgeBox.getChildren().addAll(vertex1Label, vertex1);
        edgeBox.getChildren().addAll(vertex2Label, vertex2);
        edgeBox.setSpacing(10);
        edgeBox.setAlignment(Pos.CENTER);

This is the output I’m getting.

This is the output I feel I should be getting.

This is the full code for the class if it helps. Other elements will be added to the pane when I can figure out my alignment issue. MyGraphPane extends Pane.
