Table.getHeight() always returns 0 though it shouldn't

Question

I'm trying to arrange and scale some elements inside a table and I need to know the Table's height in order to achieve all that. The problem is that whenever I try to get its height it always returns 0 even though the table is obviously on the screen and has a definite size. Why is that?

table_height = table.getHeight();

Answer 1

I suggest you to use the method pack() on the table before calling getHeight(). This will set your table its height and width.

table.pack();
table_height = table.getHeight();
