2.2.3 Window Operations
Opening a Window
To be able to work in a window, it must first be opened.

wish to open. The window is opened in the foreground and is active.
NOTE
On the desktop (root window) you need to click on the icon of the application program only one time.
Moving a Window
When a new window is opened it may partially conceal other windows. To be able to nevertheless see all
information of the windows underneath, the windows can be moved around the screen to different positions.
● Click on title bar by pressing and holding left mouse button.
● Slide the mouse on your desktop thus dragging the window to the new position. When so doing,
the mouse cursor has an x shape. When the window is moved only the outline of the window is

active
. Also those windows can be activated that are positioned
in the background underneath other windows and which are partially concealed.
● Click anywhere inside window you wish to activate. The mouse cursor changes to an arrowhead
when so doing. The selected window jumps to the foreground and is active, whereas the pre-
viously active window is
inactive
.
● The window frame of the active window in the foreground has a different color than those of the
inactive windows which have a light-gray frame.
Rearranging Window Stack

must be used:
● Press and hold Alt key and simultaneously press Tab key one time to move the topmost window
to the lowermost position in each case.

Changing a Window into an Icon (Minimizing)
As you work, your screen can become cluttered with windows. This can be avoided by iconifying (minimizing)
windows. To minimize a window, activate FILE --> Iconify on the menu. When so doing, the minimized
window is not closed, but the programs continue to execute in an iconified window.
● In the window to be minimized select menu option FILE --> Iconify.
The window immediately changes into an icon and appears on the desktop on a colored back-
ground. The colored icon is an indication that the window has been minimized.
By clicking on the icon the window is restored to its previous size.
NOTE
The menu option
Iconify
is not available in all windows so that only some of the windows can be
minimized.
Scrolling Contents of a Window
When a display area contains more information than can fit in a window, vertical and horizontal
scroll bars
are provided along the right and bottom edges of a display area (see Fig. 2.2.2).
At each end of the scroll bars
arrow buttons
are provided and a rectangular
scroll box
moves within the
scroll bars between the arrow buttons. The position of the scroll box indicates which portion of the file can
currently be seen in the window. Otherwise invisible file contents can thus come into view by using the
elements of the scroll bar.
Scrolling line-by-line
● Click on the up or down arrow button in the right scroll bar by pressing left mouse button. With
each click of the mouse the contents of the window move up or down by one line. The scroll box
reflecting the relative position within a document moves up or down accordingly.
Continuous scrolling:
● Click on the down arrow button in the right scroll bar by pressing the left mouse button; keep
mouse button depressed until scrolling operation is terminated or specific location has been
reached.
● Release mouse button. The last part of the file or the desired section is displayed in the window.
● Moving the scroll box:
● With the mouse cursor point at the scroll box in the right scroll bar, click with the left mouse button
and keeping the mouse button depressed slowly move mouse cursor in upward or downward
direction.
Thus the scroll box is moved within the scroll bar and parallel to it the contents of the file.
● Release mouse button once the desired file contents come into view inside the window.
Scrolling to the left/right
● Proceed as for scrolling up/down, but using the horizontal scroll bar at the bottom edge of the
window.
