public int tabForCoordinate(JTabbedPane pane,

getTabBounds

protected Rectangle getTabBounds(int tabIndex,
                                 Rectangle dest)

Returns the bounds of the specified tab in the coordinate space of the JTabbedPane component. This is required because the tab rects are by default defined in the coordinate space of the component where they are rendered, which could be the JTabbedPane (for WRAP_TAB_LAYOUT) or a ScrollableTabPanel (SCROLL_TAB_LAYOUT). This method should be used whenever the tab rectangle must be relative to the JTabbedPane itself and the result should be placed in a designated Rectangle object (rather than instantiating and returning a new Rectangle each time). The tab index parameter must be a valid tabbed pane tab index (0 to tab count - 1, inclusive). The destination rectangle parameter must be a valid Rectangle instance. The handling of invalid parameters is unspecified.

Parameters:: tabIndex - the index of the tab; dest - the rectangle where the result should be placed
Returns:: the resulting rectangle
