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

getTabAtLocation

protected int getTabAtLocation(int x,
                               int y)

Returns the tab index which intersects the specified point in the coordinate space of the component where the tabs are actually rendered, which could be the JTabbedPane (for WRAP_TAB_LAYOUT) or a ScrollableTabPanel (SCROLL_TAB_LAYOUT).

getClosestTab

protected int getClosestTab(int x,
                            int y)

Returns the index of the tab closest to the passed in location, note that the returned tab may not contain the location x,y.

the text view to render the tab's text or null if no specialized rendering is required
