Method Detail

macOSLookAndFeel

public static boolean macOSLookAndFeel()

Return true if we are running under MacOS look and feel or if the ptolemy.ptII.MacOS property is defined. To define ptolemy.ptII.MacOS, invoke Vergil with java -Dptolemy.ptII.MacOS=true -classpath $PTII ptolemy.vergil.VergilApplication Or, under Cygwin:

  export JAVAFLAGS=-Dptolemy.ptII.MacOS=true
  $PTII/bin/vergil
  

If the ptolemy.ptII.MacOS property is set to true, this method prints the message "ptolemy.ptII.MacOS = true property detected".

Returns:

True if the look and feel starts with "Mac OS" or the ptolemy.ptII.MacOS property is set to true.

useFileDialog

public static boolean useFileDialog()

Return true if java.awt.FileDialog should be used instead of javax.swing.JFileChooser. Certain platforms such as Mac OS X have a much better implementation of java.awt.FileDialog than they do of javax.swing.JFileChooser.

If the ptolemy.ptII.useFileDialog property is set to "true", then return true. If the ptolemy.ptII.useFileDialog property is set to any other value, return false. If the ptolemy.ptII.useFileDialog property is not set, then return the value of #macOSLookAndFeel().

To define ptolemy.ptII.useFileDialog, invoke Vergil with java -Dptolemy.ptII.useFileDialog=true -classpath $PTII ptolemy.vergil.VergilApplication Or, under Cygwin or bash:

  export JAVAFLAGS=-Dptolemy.ptII.useFileDialog=true
  $PTII/bin/vergil
  

Returns:

true if java.awt.FileDialog should be used.
