    public class QWorkspace

extends QWidget

The `QWorkspace` widget provides a workspace window that can be used in an MDI application. This class is deprecated. Use `QMdiArea` instead.

Multiple Document Interface (MDI) applications are typically composed of a main window containing a menu bar, a toolbar, and a central `QWorkspace` widget. The workspace itself is used to display a number of child windows, each of which is a widget.

The workspace itself is an ordinary Qt widget. It has a standard constructor that takes a parent widget. Workspaces can be placed in any layout, but are typically given as the central widget in a `QMainWindow`:

        public MainWindow()
        {
            workspace = new QWorkspace();
            setCentralWidget(workspace);
            // ...
        }

Child windows (MDI windows) are standard Qt widgets that are inserted into the workspace with `addWindow()`. As with top-level widgets, you can call functions such as `show()`, `hide()`, `showMaximized()`, and setWindowTitle() on a child window to change its appearance within the workspace. You can also provide widget flags to determine the layout of the decoration or the behavior of the widget itself.

To change or retrieve the geometry of a child window, you must operate on its `parentWidget()`. The `parentWidget()` provides access to the decorated frame that contains the child window widget. When a child window is maximised, its decorated frame is hidden. If the top-level widget contains a menu bar, it will display the maximised window's operations menu to the left of the menu entries, and the window's controls to the right.

A child window becomes active when it gets the keyboard focus, or when `setFocus()` is called. The user can activate a window by moving focus in the usual ways, for example by clicking a window or by pressing Tab. The workspace emits a signal `windowActivated()` when the active window changes, and the function `activeWindow()` returns a pointer to the active child window, or 0 if no window is active.

The convenience function `windowList()` returns a list of all child windows. This information could be used in a popup menu containing a list of windows, for example. This feature is also available as part of the Window Menu Solution.

`QWorkspace` provides two built-in layout strategies for child windows: `cascade()` and `tile()`. Both are slots so you can easily connect menu entries to them.

If you want your users to be able to work with child windows larger than the visible workspace area, set the `scrollBarsEnabled` property to true.

Field Detail

### windowActivated

    public final QSignalEmitter.Signal1 windowActivated

  This signal is emitted when the child window `w` becomes active. Note that `w` can be 0, and that more than one signal may be emitted for a single activation event.

See also:
  `activeWindow()`, and `windowList()`.

                                   Qt.WindowType[] flags)

  Adds widget `w` as new sub window to the workspace. If `flags` are non-zero, they will override the flags set on the widget.

  Returns the widget used for the window frame.

  To remove the widget `w` from the workspace, simply call `setParent()` with the new parent (or 0 to make it a stand-alone window).

### addWindow

    public final QWidget addWindow(QWidget w)

  Adds widget `w` as new sub window to the workspace. If `flags` are non-zero, they will override the flags set on the widget.

  Returns the widget used for the window frame.

  To remove the widget `w` from the workspace, simply call `setParent()` with the new parent (or 0 to make it a stand-alone window).

### addWindow

    public final QWidget addWindow(QWidget w,
                                   Qt.WindowFlags flags)

  Adds widget `w` as new sub window to the workspace. If `flags` are non-zero, they will override the flags set on the widget.

  Returns the widget used for the window frame.

  To remove the widget `w` from the workspace, simply call `setParent()` with the new parent (or 0 to make it a stand-alone window).

### arrangeIcons

    public final void arrangeIcons()

  Arranges all iconified windows at the bottom of the workspace.

See also:
  `cascade()`, and `tile()`.

### background

    public final QBrush background()

  This property holds the workspace's background.

### cascade

    public final void cascade()

  Arranges all the child windows in a cascade pattern.

See also:
  `tile()`, and `arrangeIcons()`.

### closeActiveWindow

    public final void closeActiveWindow()

  Closes the child window that is currently active.

See also:
  `closeAllWindows()`.

### closeAllWindows

    public final void closeAllWindows()

  Closes all child windows.

  If any child window fails to accept the close event, the remaining windows will remain open.

See also:
  `closeActiveWindow()`.

### scrollBarsEnabled

    public final boolean scrollBarsEnabled()

  This property holds whether the workspace provides scroll bars. If this property is true, the workspace will provide scroll bars if any of the child windows extend beyond the edges of the visible workspace. The workspace area will automatically increase to contain child windows if they are resized beyond the right or bottom edges of the visible area.

  If this property is false (the default), resizing child windows out of the visible area of the workspace is not permitted, although it is still possible to position them partially outside the visible area.

### setActiveWindow

The workspace area will automatically increase to contain child windows if they are resized beyond the right or bottom edges of the visible area.

  If this property is false (the default), resizing child windows out of the visible area of the workspace is not permitted, although it is still possible to position them partially outside the visible area.

### tile

### windowList

    public final java.util.List windowList(QWorkspace.WindowOrder order)

  Returns a list of all visible or minimized child windows. If `order` is `CreationOrder` (the default), the windows are listed in the order in which they were inserted into the workspace. If `order` is `StackingOrder` , the windows are listed in their stacking order, with the topmost window as the last item in the list.

### fromNativePointer

    public static QWorkspace fromNativePointer(QNativePointer nativePointer)

  This method returns the QWorkspace instance pointed to by `nativePointer`.
