Package anlavn.ui.filechooser

Class WindowsFileChooser

java.lang.Object
anlavn.ui.filechooser.WindowsFileChooser
public class WindowsFileChooser extends Object
The native Windows file chooser dialog. Example: WindowsFileChooser fc = new WindowsFileChooser("C:\\"); fc.addFilter("All Files", "*"); fc.addFilter("Text files", "txt", "log", "xml", "css", "html"); fc.addFilter("Source code", "java", "c", "cpp", "cc", "h", "hpp"); fc.addFilter("Binary files", "exe", "class", "jar", "dll", "so"); if (fc.showOpenDialog(parent)) { File f = fc.getSelectedFile(); // do something with f } Note that although you can set the initial directory Windows will determine the initial directory according to the following rules (the initial directory is referred to as "lpstrInitialDir"): Windows 7: 1. If lpstrInitialDir has the same value as was passed the first time the application used an Open or Save As dialog box, the path most recently selected by the user is used as the initial directory. 2. Otherwise, if lpstrFile contains a path, that path is the initial directory. 3. Otherwise, if lpstrInitialDir is not NULL, it specifies the initial directory. 4. If lpstrInitialDir is NULL and the current directory contains any files of the specified filter types, the initial directory is the current directory. 5. Otherwise, the initial directory is the personal files directory of the current user. 6. Otherwise, the initial directory is the Desktop folder. Windows 2000/XP/Vista: 1. If lpstrFile contains a path, that path is the initial directory. 2. Otherwise, lpstrInitialDir specifies the initial directory. 3. Otherwise, if the application has used an Open or Save As dialog box in the past, the path most recently used is selected as the initial directory. However, if an application is not run for a long time, its saved selected path is discarded. 4. If lpstrInitialDir is NULL and the current directory contains any files of the specified filter types, the initial directory is the current directory. 5. Otherwise, the initial directory is the personal files directory of the current user. 6. Otherwise, the initial directory is the Desktop folder. Therefore you probably want to use an exe wrapper like WinRun4J in order for this to work properly on Windows 7. Otherwise multiple programs may interfere with each other. Unfortunately there doesn't seem to be a way to override this behaviour.
