Method

intgetOffsetOfVirtualColumn(Segment seg, int tabSize, int column, int[] totalVirtualWidth)
Returns the array offset of a virtual column number (taking tabs into account) in the segment. 
int virtualPosition = 0;
for (int i = 0; i < seg.count; i++) {
    char ch = seg.array[seg.offset + i];
    if (ch == '\t') {
        int tabWidth = tabSize - virtualPosition % tabSize;
        if (virtualPosition >= column)
            return i;
        else

if (leftIndent >= 0)
...
intgetTabbedPaneComponentIndex(JTabbedPane tabbedPane, String title)
get Tabbed Pane Component Index 
int index = -Integer.MAX_VALUE;

JTabbedPanegetTabbedPaneFor(Component c)
Get the tabbed pane for a component 
if (c == null) {
    return null;
if (c instanceof JTabbedPane) {

return getTabbedPaneFor(c.getParent());
intgetTabComponentIndex(JTabbedPane tbp, Component component)
Returns index of a tab's component inside tabbed pane 
int count = tbp.getTabCount();
for (int i = 0; i < count; i++) {
    if (component == tbp.getComponentAt(i)) {
        return i;

intgetTabPaneLeadingPlacement()
Gets the tab pane leading placement. 
return isLeftOrientation() ? JTabbedPane.LEFT : JTabbedPane.RIGHT;
intgetTabsHeight()

intgetVirtualWidth(Segment seg, int tabSize)
Returns the virtual column number (taking tabs into account) of the specified offset in the segment. 
int virtualPosition = 0;
for (int i = 0; i < seg.count; i++) {
    char ch = seg.array[seg.offset + i];
    if (ch == '\t') {
        virtualPosition += tabSize - virtualPosition % tabSize;
    } else {
        ++virtualPosition;
return virtualPosition;
