arguments of gridpane add method

Question

When adding a button to a gridpane we use gridPane.add(btn1, 0,0,1,1);. What do the last two integer arguments do?

Answer 1

• I am not sure if this answers your question but the first two integer represents the column and row index. The last two represents the columnSpan and rowSpan (the number of rows the child's layout area spans horizontally). You can read more about it here:
