Package docking.widgets.filechooser

Class GhidraFileChooser

  • All Implemented Interfaces:
    ActionContextProvider, GhidraFileChooserListener, StatusListener, TaskListener, java.io.FileFilter
    public class GhidraFileChooser
extends DialogComponentProvider
implements GhidraFileChooserListener, java.io.FileFilter
    An implementation of a file chooser dialog. This class is designed to emulate the JFileChooser, but it removes the network locking issue. When a network drive is down, the JFileChooser can take several minutes to come up. Why use this file chooser over JFileChooser?? Let me enumerate the reasons...
    1. JFileChooser cannot show hidden/system files, but we can!
    2. JFileChooser does not properly consume key strokes (global actions in docking windows)
    3. This class is threaded, so loading delays do not lock the GUI
    4. This class provides shortcut buttons similar to those of the Windows native chooser

      • getSelectedFile

        public java.io.File getSelectedFile()
        Returns the selected file. This can be set either by the programmer via setSelectedFile(File) or by a user action, such as either typing the filename into the UI or selecting the file from a list in the UI.
        Returns:

        Returns the selected file. This can be set either by the programmer via setSelectedFile(File) or by a user action, such as either typing the filename into the UI or selecting the file from a list in the UI.

        Note: this method can be called after the chooser has been shown, in which case the value returned has been validated by the chooser. Also, the method may be called while the chooser is showing (like from a test thread). In this case, the selected file will not have been validated by the chooser.

        Parameters:
        show - if true then the dialog is displayed

        the selected file; null if cancelled or no file was selected

      • setSelectedFile

        public void setSelectedFile​(java.io.File file)
        Sets the selected file. If the file's parent directory is not the current directory, changes the current directory to be the file's parent directory.

        If the given file is a directory, then it's parent directory will be made the current directory and the directory represented by the file will be selected within the parent directory.

        If the given file does not exist, then the following will happen:

        • If the parent directory of the file exists, then the parent directory will be made the current directory and the name of the file will be put into the filename textfield; otherwise,
        • If the parent file does not exist, then the selection is cleared.

        If the given file is null, then the selected file state is cleared.

        Parameters:
        file - the selected file
        See Also:
        getSelectedFile()

      • show

        public void show()

      • getCurrentDirectory

        public java.io.File getCurrentDirectory()
        Returns the current directory.
        Returns:
        the current directory
        See Also:
        setCurrentDirectory(java.io.File)

      • setCurrentDirectory

        public void setCurrentDirectory​(java.io.File directory)
        Sets the current directory. Passing in null sets the file chooser to point to the user's default directory. This default depends on the operating system. It is typically the "My Documents" folder on Windows, and the user's home directory on Unix.
        If the file passed in as currentDirectory is not a directory, the parent of the file will be used as the currentDirectory. If the parent is not traversable, then it will walk up the parent tree until it finds a traversable directory, or hits the root of the file system.
        Parameters:
        directory - the current directory to point to
        See Also:
        getCurrentDirectory()
