I have a JSlider with a min of 0 and a max of 10,000. I have the major tick marks set at 1,000. If I were to paint the labels now they would show up as 0, 1000, 2000, 3000, 4000, etc. What I would like to be shown would be 0, 1, 2, 3, 4, 5, etc. What would be a good way to accomplish this task?
using JSlider.setLabelTable(Dictionary)
EDIT
Alternatively you can rely on predefined label UI and just change the label text:
Enumeration e = jSlider.getLabelTable().keys();
while (e.hasMoreElements()) {
Integer i = (Integer) e.nextElement();
JLabel label = (JLabel) jSlider.getLabelTable().get(i);
label.setText(String.valueOf(i / 1000));
}
You could use JSlider.setLabelTable(Dictionary)
to set specific labels for the values you wish to render differently; e.g.
JSlider slider = ...
Dictionary dict = new Hashtable();
for (int i=0; i<=10000; i += 1000) {
dict.put(i, new JLabel(Integer.toString(i / 1000)));
}
slider.setLabelTable(dict);
