installGtkPopupBugWorkaround

public static void installGtkPopupBugWorkaround()

Swing menus are looking pretty bad on Linux when the GTK LaF is used (See bug #6925412). It will most likely never be fixed anytime soon so this method provides a workaround for it. It uses reflection to change the GTK style objects of Swing so popup menu borders have a minimum thickness of 1 and menu separators have a minimum vertical thickness of 1. This code was taken from K's Cluttered Loft (Klaus Reimer) at http://www.ailis.de and as far as im aware is in the public domain as it has no attached license if this proves incorrect then I will remove it immediately.

fixGtkThickness

public static void fixGtkThickness(java.lang.Object style,
                   java.lang.String fieldName)
                            throws java.lang.Exception

Called internally by installGtkPopupBugWorkaround to fix the thickness of a GTK style field by setting it to a minimum value of 1. This code was taken from K's Cluttered Loft (Klaus Reimer) at http://www.ailis.de and as far as im aware is in the public domain as it has no attached license if this proves incorrect then I will remove it immediately.

Parameters:

style - The GTK style object.

fieldName - The field name.

Throws:

java.lang.Exception - When reflection fails.

getGtkStyle

public static java.lang.Object getGtkStyle(java.lang.Object styleFactory,
                           javax.swing.JComponent component,
                           java.lang.String regionName)
                                    throws java.lang.Exception

Called internally by installGtkPopupBugWorkaround. Returns a specific GTK style object.

Parameters:

styleFactory - The GTK style factory.

component - The target component of the style.

regionName - The name of the target region of the style.

Returns:

The GTK style.

Throws:

java.lang.Exception - When reflection fails. This code was taken from K's Cluttered Loft (Klaus Reimer) at http://www.ailis.de and as far as im aware is in the public domain as it has no attached license if this proves incorrect then I will remove it immediately.
