GridLayout不起作用

Question

here's my code:

PresidentVote(){
        setName("PresCandidate");
        setBorder(BorderFactory.createTitledBorder("Candidates for President"));

        for(int row=0; row<PresidentTable.tblNatPresident.getRowCount(); row++){
            setLayout(new GridLayout(row, 2));
            String name=PresidentTable.tblNatPresident.getValueAt(row, 0).toString();

            JLabel lblName=new JLabel(name);
            JRadioButton radioVote=new JRadioButton();
            lblName.setBorder(BorderFactory.createLineBorder(Color.RED));

            add(lblName); add(radioVote);
        }
    }

but the one that will appear looks like this:

and i'm trying to achieve like this:

name | radiobutton

name | radiobutton

and the number of rows will depend on how many rows the jtables was. and only two columns.

i don't really know i mean did i violate something in the codes? or is there something that i should put for it to properly work? please help thank you so much :)

Answer 1

If you want the radio button and a label to be put together in a single cell, wrap them in a panel and put the panel into the cell. Remember that the panel needs it's own layout (although the default flow layout may work for you)

As an alternative, I think setting the text (label?) of the radio button might be cleaner (although slightly less flexible).

Answer 2

For starters you need to move your setLayout before the loop as it is just overriding it each iteration for no reason, therefore you need to change the y value to the amount of rows. Secondly change swap the values within the grid layout so it looks something like this...

setLayout(new GridLayout(2, PresidentTable.tblNatPresident.getRowCount()));
