getAcceleratorTooltip

public static java.lang.String getAcceleratorTooltip(int cmdID)

Parameters:

cmdID - the ID of a command present in the global keymap

Returns:

the accelerator string of the specified command

Builds a tooltip for a command in the form of cmd-name[ " (" accelerator ")" ]

Parameters:

cmdID -

Returns:

the tooltip

component -

getBestAccelerator

public static javax.swing.KeyStroke getBestAccelerator(KeyStrokeMap ksm,
                                                       int nCmdID)

Return the 'best' accelerator found in the map for the specified command ID. The 'best' is defined as an accelerator with a maximum of 1 keystroke (not a sequence) F-keys are preferred to letters which are preferred to others (Ins,Del, Home, ...)
