I need to reduce the size of a JCheckBox item, which has no text. So far I tried to override the methods getPreferredSize()
and getMaximumSize()
. Also setting the Font size or the size of the JCheckBox itself doesn't evoke any changes. Is there a way to achieve this?
If you're talking about an Icon that is added to the JCheckBox, then best would be to create a new Icon from a new Image that is a resize of the original image. You can do this with a Image by calling the yourImage.getScaledInstance(...);
method. Once you get the new image, create a new ImageIcon(newImage)
and use it with your JCheckBox.
eg
Image oldImage = oldIcon.getImage();
Image newImage = oldImage.getScaledInstance(newWidth, newHeight,
Image.SCALE_DEFAULT);
Icon newIcon = new ImageIcon(newImage);
checkBox.setIcon(newIcon);
getPreferredSize
and getMaximumSize
only return the values assigned to preferredSize
and maximumSize
, respectively, for the JCheckBox
object. If you want to change these values, use setPreferredSize
and setMaximumSize
instead:
jCheckBox.setPreferredSize(new Dimension(100, 300));
and/or:
jCheckBox.setMaximumSize(new Dimension(200, 600));
You can override the paint function like this:
final JCheckBox cb = new JCheckBox("",autoChangeTab) {
@Override
public void paint(Graphics g) {
Graphics2D g2d = (Graphics2D) g;
g2d.scale(.9, .9);
super.paint(g);
}
};
