<h3>e993. Customizing Tab Stops in a JTextPane Component</h3>
This example demonstrates the four types of tabs that can be used in a
<code>JTextPane</code>. In a left-aligned tab, characters appear after the
tab. In a right-aligned tab, characters appear in front of the tab.
In a center-aligned tab, characters appear centered around the tab.
In a decimal-aligned tab, the decimal point is anchored at the tab.
<pre> // Create a text pane
JTextPane textPane = new JTextPane();
// Create one of each type of tab stop
java.util.List list = new ArrayList();
// Create a left-aligned tab stop at 100 pixels from the left margin
float pos = <font color="#0066ff"><i>100</i></font>;
int align = TabStop.ALIGN_LEFT;
int leader = TabStop.LEAD_NONE;
TabStop tstop = new TabStop(pos, align, leader);
list.add(tstop);
// Create a right-aligned tab stop at 200 pixels from the left margin
pos = <font color="#0066ff"><i>200</i></font>;
align = TabStop.ALIGN_RIGHT;
leader = TabStop.LEAD_NONE;
tstop = new TabStop(pos, align, leader);
list.add(tstop);
// Create a center-aligned tab stop at 300 pixels from the left margin
pos = <font color="#0066ff"><i>300</i></font>;
align = TabStop.ALIGN_CENTER;
leader = TabStop.LEAD_NONE;
tstop = new TabStop(pos, align, leader);
list.add(tstop);
// Create a decimal-aligned tab stop at 400 pixels from the left margin
pos = <font color="#0066ff"><i>400</i></font>;
align = TabStop.ALIGN_DECIMAL;
leader = TabStop.LEAD_NONE;
tstop = new TabStop(pos, align, leader);
list.add(tstop);
// Create a tab set from the tab stops
TabStop[] tstops = (TabStop[])list.toArray(new TabStop[0]);
TabSet tabs = new TabSet(tstops);
// Add the tab set to the logical style;
// the logical style is inherited by all paragraphs
Style style = textPane.getLogicalStyle();
StyleConstants.setTabSet(style, tabs);
textPane.setLogicalStyle(style);
