Hi,
I'm trying to print a string on the center of a window using GridBagLayout.
All I see printed is a part of the string I expect (the current month) instead of the whole string.
I don't seem to be able to spot where the error is and I'd appreciate if you could tell me.

class DrawTextPanel extends JPanel {
String text;
String font;
int size;
Font fontFamily;
DrawTextPanel(String text, String font, int size) {
this.text = text;
this.font = font;
this.size = size;
fontFamily = new Font(font, Font.BOLD, size);
}
public void paintComponent(Graphics comp) {
Graphics2D g2d = (Graphics2D) comp;
g2d.setFont(fontFamily);
g2d.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);
FontMetrics fm = comp.getFontMetrics(fontFamily);
int stringHeight = fm.getHeight();
int stringWidth = fm.stringWidth(text);
int yCoordinate = (getSize().height + stringHeight)/2;
int xCoordinate = (getSize().width - stringWidth)/2;
g2d.drawString(text, xCoordinate, yCoordinate);
repaint();
}
}
class Gui extends JFrame {
String month;
JPanel mainPane = new JPanel();
GridBagLayout gbLayout = new GridBagLayout();
GregorianCalendar gc;
Gui() {
super("test");
setSize(200, 300);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
gc = new GregorianCalendar();
month = String.valueOf(gc.get(Calendar.MONTH));
mainPane.setLayout(gbLayout);
addText(month, mainPane, "Verdana", 20, 0, 0, 10, 2, 100, 2, GridBagConstraints.CENTER, GridBagConstraints.NONE);
add(mainPane);
setVisible(true);
}
private void addText(String text, Container cont, String font, int size, int gx, int gy, int gwidth, int gheight, int wx, int wy, int anch, int fi) {
GridBagConstraints gbc = new GridBagConstraints();
gbc.gridx = gx;
gbc.gridy = gy;
gbc.gridwidth = gwidth;
gbc.gridheight = gheight;
gbc.weightx = wx;
gbc.weighty = wy;
gbc.anchor = anch;
gbc.fill = fi;
DrawTextPanel dtComponent = new DrawTextPanel(text, font, size);
gbLayout.setConstraints(dtComponent, gbc);
cont.add(dtComponent);
}
}
public class Test {
public static void main(String[] args) {
Gui gui = new Gui();
}
}Thanks for the help.
