1. This is the wrong forum for swing questions2. *mindreading the code in question* You are using a single GridbagContraint instance for all components, not resetting the values you set for your 2nd component before setting the following ones.

Ah, no, you don't have to create different instances. But you have to set the appropriate values before adding the component with the gbc.

There is not that much wrong with it. Btw. you should use the code-tag to make the code better readable.

> c31.insets=new Insets(15,15,15,15);

> c31.insets=new Insets(5,5,5,5);

> c31.anchor = GridBagConstraints.NORTH;

> c31.anchor = GridBagConstraints.SOUTH;

Assigning twice does not make sense, as the last assignment overrides the first. And you actually do not want NORTH or SOUTH anchoring. I will add the missing assignments below:> title_lab=new JLabel("Permanent Staff Tracker");

> title_lab.setFont(fon);

> title_lab.setForeground(Color.black);

> c31.weightx =0.3;

> c31.gridx=0;

> c31.gridy=0;

c31.anchor=GridBagConstraints.CENTER; // centers the title

c31.gridwidth=GridBagConstraints.REMAINDER; // spans over all cells

> pane_cli.add(title_lab,c31);

>

> clid_lab= new JLabel("Client ID");

> c31.gridx=0;

> c31.gridy=1;

c31.anchor=GridBagConstraints.WEST; // left align from now on

c31.gridwidth=1; // only take one cell per label and field from now on

> pane_cli.add(clid_lab,c31);

With the buttons at the bottom there are two solutions: make all fields span over three cells or pack the buttons into a new JPanel and add the panel to the pane. The latter is much nicer, as it is independent from the number of cells used before. The additional panel would look somewhat like this:buttonPanel = new JPanel();

login_button= new JButton("SUBMIT");

buttonPanel.add(login_button);

update_button= new JButton("UPDATE");

buttonPanel.add(update_button);

delete_button= new JButton("DELETE");

buttonPanel.add(delete_button);

c31.gridx=1;

c31.gridy=7;

pane_cli.add(buttonPanel, c31);
