I have custom JButton class with gradient background and rounded corners. Should I override setText() or what should I do to display text upon it? setText("text") has no effect.
UPD: I've tried setContentAreaFilled(false), like MadProgrammer suggested, and it solved this problem, but another appeared. I have such buttons on different tabs, and when they are repainted, they appear for some milliseconds like they all were at the same tab. Updated code is here:
public class DarkGradientButton extends JButton {
private Color startColor = new Color(178, 178, 178);
private Color endColor = new Color(131, 131, 131);
private Color disstartColor = new Color(252, 252, 252);
private Color disendColor = new Color(221, 221, 221);
private Color enstartColor = new Color(178, 178, 178);
private Color enendColor = new Color(131, 131, 131);
public DarkGradientButton(String text, ImageIcon ii) {
super(text, ii);
this.setContentAreaFilled(false);
}
public DarkGradientButton() {
super();
this.setContentAreaFilled(false);
}
@Override
protected void paintComponent( Graphics g )
{
g.setColor(new Color(246,250,245));
int h = getHeight();
int w = getWidth();
GradientPaint gradientPaint = new GradientPaint( 0 , 0 , startColor , 0 , h , endColor );
int[] x = {0, 1, w-1, w, w, w-1, w-2, 2, 1, 0};
int[] y = {1, 0, 0, 1, h-3, h-2, h-1, h-1, h-2, h-3};
Graphics2D graphics2D = (Graphics2D)g;
graphics2D.setPaint( gradientPaint );
graphics2D.fillPolygon(x, y, x.length);
graphics2D.setColor(this.getForeground());
super.paintComponent( g );
}
public void makeDisable() {
startColor = disstartColor;
endColor = disendColor;
Graphics g = this.getGraphics();
paintComponent(g);
this.repaint();
}
public void makeEnable() {
startColor = enstartColor;
endColor = enendColor;
Graphics g = this.getGraphics();
paintComponent(g);
this.repaint();
}
}
Buttons on tabs (that is what Netbeans generated for me):
callStartButton = new gui.DarkGradientButton(language[25], new ImageIcon("pic\\call-start.png"));
callStartButton.setBorder(null);
callStartButton.setForeground(new java.awt.Color(255, 255, 255));
callStartButton.setFont(new java.awt.Font("Arial", 1, 12)); // NOI18N
callStartButton.setPreferredSize(new java.awt.Dimension(95, 23));
callStartButton.addActionListener(new java.awt.event.ActionListener() {
public void actionPerformed(java.awt.event.ActionEvent evt) {
callStartButtonActionPerformed(evt);
}
});

The main reason setText isn't working is because your painting over it
g.fillRect(0, 0, w, h);
You'll find that he ui is rendering the text in super.paintComponent(g) call, then you're painting over it
UPDATE
I used the following code to show some tabs and couldn't find anything wrong...
package test;

public class TestButton {
public static void main(String[] args) {

List gradient;
if (grad instanceof List) {
gradient = (List) grad;
System.out.println(gradient.get(0));
System.out.println(gradient.get(1));
System.out.println(gradient.get(2));
System.out.println(gradient.get(3));
System.out.println(gradient.get(4));
//gradient.set(2, new ColorUIResource(221, 232, 243));//origal Color
//gradient.set(2, new ColorUIResource(255, 255, 255));//origal Color
//gradient.set(2, new ColorUIResource(184, 207, 229));//origal Color
gradient.set(2, new ColorUIResource(190, 230, 240));
gradient.set(3, new ColorUIResource(240, 240, 240));
