Class MnemonicSolver

java.lang.Object
oracle.ide.util.MnemonicSolver

public class MnemonicSolver

extends java.lang.Object

This class can be used to resolve mnemonic conflicts in menus. The class manages a list of MnemonicSolver.MenuLabel recording all labels whose mnemonics need to be resolved. To use the mnemonic solver class you create a instance of the solver, you then add a pull down menu, popup menu, or individual menu items to the solver. Once all menu items are added you just call the solve() method to put this class to work. The registered menu items may have their mnemonics changed when the solve() method is executed.

Method Detail

addMenuLabel

public MnemonicSolver.MenuLabel addMenuLabel(java.lang.String text)

Adds a new menu label to the list of labels whose mnemonics need to be resolved.

addMenuLabel

public MnemonicSolver.MenuLabel addMenuLabel(java.lang.String text,
                                             int mnemonic)

Adds a new menu label to the list of labels whose mnemonic needs to be resolved. The specified mnemonic is the suggested mnemonic for the label. If conflicts exist, the suggested mnemonic may not be used.

addMenuLabel

public MnemonicSolver.MenuLabel addMenuLabel(java.lang.String text,
                                             int mnemonic,

Adds a new menu label to the list of labels whose mnemonic needs to be resolved. The specified mnemonic is the suggested mnemonic for the label. If the parameter fixed is specified as true, the suggested mnemonic will be used unless the same mnemonic is also fixed by another menu. In this case the menu with smaller number of characters will have preference in using the specified mnemonic.

addMenuLabel

public MnemonicSolver.MenuLabel addMenuLabel(javax.swing.AbstractButton menuItem)

Adds a new menuItem to the list of menu items whose mnemonic needs be resolved. The menu item mnemonic, if set, is used as the suggested mnemonic for the menu label. If conflicts exist, the suggested mnemonic may not be used.

addMenuLabel

public MnemonicSolver.MenuLabel addMenuLabel(javax.swing.JMenuItem menuItem)

Adds a new menuItem to the list of menu items whose mnemonic needs be resolved. The menu item mnemonic, if set, is used as the suggested mnemonic for the menu label. If conflicts exist, the suggested mnemonic may not be used.

addMenuLabel

Adds a new menuItem to the list of menu items whose mnemonic needs be resolved. The menu item mnemonic, if set, is used as the suggested mnemonic for the menu label. If the parameter fixed is specified as true, the suggested mnemonic will be used unless the same mnemonic is also fixed by another menu. In this case the menu with smaller number of characters will have preference in using the specified mnemonic. If the specified menuItem is already registered this method will only set the given fixed value.

addMenuLabel

public MnemonicSolver.MenuLabel addMenuLabel(javax.swing.JMenuItem menuItem,
                                             boolean fixed)

Adds a new menuItem to the list of menu items whose mnemonic needs be resolved. The menu item mnemonic, if set, is used as the suggested mnemonic for the menu label. If the parameter fixed is specified as true, the suggested mnemonic will be used unless the same mnemonic is also fixed by another menu. In this case the menu with smaller number of characters will have preference in using the specified mnemonic. If the specified menuItem is already registered this method will only set the given fixed value.
