* 解説 [#explanation]
- [https://stackoverflow.com/questions/16292502/how-can-i-start-the-jfilechooser-in-the-details-view java - How can I start the JFileChooser in the Details view? - Stack Overflow]で紹介されている`ActionMap`から`viewTypeDetails`アクションを取得して`DetailsView`(詳細)に切り替え
#code{{
// @see javax/swing/plaf/basic/BasicFileChooserUI.java
ActionMap map = new ActionMapUIResource();
Action refreshAction = new UIAction(FilePane.ACTION_REFRESH) {
public void actionPerformed(ActionEvent e) {
getFileChooser().rescanCurrentDirectory();
}
};
map.put(FilePane.ACTION_APPROVE_SELECTION, getApproveSelectionAction());
map.put(FilePane.ACTION_CANCEL, getCancelSelectionAction());
map.put(FilePane.ACTION_REFRESH, refreshAction);
map.put(FilePane.ACTION_CHANGE_TO_PARENT_DIRECTORY, getChangeToParentDirectoryAction());
// sun.swing.FilePane.ACTION_APPROVE_SELECTION = "approveSelection";
// sun.swing.FilePane.ACTION_CANCEL = "cancelSelection";
// sun.swing.FilePane.ACTION_EDIT_FILE_NAME = "editFileName";
// sun.swing.FilePane.ACTION_REFRESH = "refresh";
// sun.swing.FilePane.ACTION_CHANGE_TO_PARENT_DIRECTORY = "Go Up";
// sun.swing.FilePane.ACTION_NEW_FOLDER = "New Folder";
// sun.swing.FilePane.ACTION_VIEW_LIST = "viewTypeList";
// sun.swing.FilePane.ACTION_VIEW_DETAILS = "viewTypeDetails";
}}
- `JFileChooser`の子で`UIManager.getIcon("FileChooser.detailsViewIcon")`アイコンが設定されている`JToggleButton`を検索、`doClick()`することで`List`から`DetailsView`(詳細)に切り替え
- `MetalLookAndFeel`などの`JFileChooser`の子で`UIManager.getIcon("FileChooser.detailsViewIcon")`アイコンが設定されている`JToggleButton`を検索、`doClick()`することで`List`から`DetailsView`(詳細)に切り替え
-- `WindowsLookAndFeel`での`JFileChooser`の`DetailsView`切り替えは`JRadioButtonMenuItem`なのでこの方法は使用不可
#code{{
// searchAndClick(chooser, UIManager.getIcon("FileChooser.detailsViewIcon"));
private static boolean searchAndClick(Container parent, Icon icon) {
for (Component c:parent.getComponents()) {
if (c instanceof JToggleButton && ((JToggleButton) c).getIcon() == icon) {
((AbstractButton) c).doClick();
return true;
} else {
if (searchAndClick((Container) c, icon)) {
return true;
}
}
}
return false;
}
}}
- 警告されるが以下のように`sun.swing.FilePane#setViewType(sun.swing.FilePane.VIEWTYPE_DETAILS)`メソッドを使用する方法もある
#code{{
FilePane filePane = (FilePane) findChildComponent(chooser, FilePane.class);
filePane.setViewType(FilePane.VIEWTYPE_DETAILS);
}}
