Constructor Detail

PgFileDialog

public PgFileDialog(java.awt.Frame frame,
                    java.lang.String title,
                    int mode)

Create a file dialog which blocks all other user interaction when visible.

Parameters:

mode - FileDialog.LOAD | FileDialog.SAVE

Method Detail

setVisible

public void setVisible(boolean flag)

Deprecated. use show() or hide()

Show file dialog and block all other user interaction. If user has chosen a file, then update the static current directory variable.

Method calls super.show(true) if flag==true. Previous version before v1.20 always called super.setVisible(true) which prevent dialog to be closed on Mac0S-X and possibly led to some other problems on Sun.

Overrides:

Version:

03.04.03, 2.00 revised (kp) Method body moved to show().
03.04.03, 1.20 revised (kp) Bug with closing dialogs removed by replacing super.setVisible with super.show.

isFileSelected

public boolean isFileSelected()
