  • Methodendetails

    • getWindow

      protected Window getWindow(Component c)

    • whenDisplayable

      protected void whenDisplayable(Component w, Runnable action)
      Execute the given action when the given window becomes displayable.

    • toRaster

      protected Raster toRaster(Shape mask)

    • toRaster

      protected Raster toRaster(Component c, Icon mask)

    • toShape

      protected Shape toShape(Raster raster)

    • setWindowAlpha

      public void setWindowAlpha(Window w, float alpha)
      Set the overall alpha transparency of the window. An alpha of 1.0 is fully opaque, 0.0 is fully transparent.

    • isWindowAlphaSupported

      public boolean isWindowAlphaSupported()
      Default: no support.

    • getAlphaCompatibleGraphicsConfiguration

      public GraphicsConfiguration getAlphaCompatibleGraphicsConfiguration()
      Return the default graphics configuration.

    • setWindowTransparent

      public void setWindowTransparent(Window w, boolean transparent)
      Set the window to be transparent. Only explicitly painted pixels will be non-transparent. All pixels will be composited with whatever is under the window using their alpha values.

    • setDoubleBuffered

      protected void setDoubleBuffered(Component root, boolean buffered)

    • setLayersTransparent

      protected void setLayersTransparent(Window w, boolean transparent)

    • setMask

      protected void setMask(Component c, Raster raster)
      Override this method to provide bitmap masking of the given heavyweight component.

    • setWindowMask

      protected void setWindowMask(Component w, Raster raster)
      Set the window mask based on the given Raster, which should be treated as a bitmap (zero/nonzero values only). A value of null means to remove the mask.

    • setWindowMask

      public void setWindowMask(Component w, Shape mask)
      Set the window mask based on a Shape.

    • setWindowMask

      public void setWindowMask(Component w, Icon mask)
      Set the window mask based on an Icon. All non-transparent pixels will be included in the mask.

    • setForceHeavyweightPopups

      protected void setForceHeavyweightPopups(Window w, boolean force)
      Use this method to ensure heavyweight popups are used in conjunction with a given window. This prevents the window's alpha setting or mask region from being applied to the popup.

    • getWindowIcon

      protected BufferedImage getWindowIcon(WinDef.HWND hwnd)
      Obtains the set icon for the window associated with the specified window handle.
      Parameter:
      hwnd - The concerning window handle.
      Gibt zurück:
      Either the window's icon or null if an error occurred.

      Requests a list of all currently available Desktop windows.
      Parameter:
      onlyVisibleWindows - Specifies whether only currently visible windows will be considered (true). That are windows which are not minimized. The WS_VISIBLE flag will be checked (see: User32.IsWindowVisible(HWND)).
