Add specific background colors to JDaychooser Dates

问题

I've developed a Java Swing application..

How can I set the background color of specific JDayChooser dates?

Thanks

回答1:

getDayPanel

public javax.swing.JPanel getDayPanel()

This returns the day panel. After that, you can:

panel.setBackground(color);  

Also:

setForeground

public void setForeground(java.awt.Color foreground)

Sets the foregroundColor color.

setDecorationBackgroundColor

public void setDecorationBackgroundColor(java.awt.Color decorationBackgroundColor)

Sets the background of days and weeks of year buttons.

回答2:

JDayChooser has a protected field that specifies the selectedColor, but it has no public interface. You can,

• Alter the default gray, in JDayChooser#init().

• Add the required methods; the new bound property will appear in JCalendarDemo.

  public Color getSelectedColor() {
      return selectedColor;
  }
  
  public void setSelectedColor(Color selectedColor) {
      this.selectedColor = selectedColor;
  }
  

As discussed here, setBackground() doesn't read well on some Look & Feel implementations. The workaround in DecoratorButton#paint() is an example.

回答3:

    JPanel jPanel = jDayChooser1.getDayPanel();

    Component component[] = jPanel.getComponents();

    for (int i = 7; i < 49; i++) {
        component[i].setBackground(Color.red);
    }

Finally got a solution to do :D
