![]() ![]() Remember that all of the window manager functions are customizable. The following pages explain the functions of the Twm menu. The Twm menu and the menu pointer appear as shown in Figure 3-2. In the standard version of twm shipped by MIT, you bring up this menu by moving the pointer to the root window and holding down the left pointer button. Twm’s Twm menu gives you access to many of the most frequently used window manipulation functions. These functions can also be invoked from a menu and will be discussed more thoroughly in the next section. Move the window, by pressing and holding down the left pointer button on the titlebar, dragging the window to a new location, and releasing the pointer button.Lower the window to the bottom of the stack, by clicking the middle pointer button on the titlebar. ![]() Raise the window to the top of the stack, by clicking the first pointer button on the titlebar.Drag the pointer to move the border the desired amount and then release the pointer button. Then, while holding down the first pointer button, move the pointer across the border you want to move. Resize the window, by pressing the first pointer button in the right-hand command button in the titlebar (which contains a group of nested squares).Iconify the window, by clicking the first pointer button (usually the leftmost) in the left-hand command button in the titlebar (it’s marked with an X).All this without having to bring up a menu or type modifier keys!

Resize allows you to change the size of a window. Iconify allows you to shrink an unneeded window so that it’s out of your way. The titlebar provides convenient access to the most commonly used window manager functions: iconify, resize, raise, and lower. This titlebar contains the name of the window (“xterm,” for example), two buttons, and a region that is highlighted when the input focus is in the associated window. When twm starts up, it places a titlebar on every window on the screen. However, there is no easy way to change the size or location of windows on the screen without a window manager. twm allows you to size and place client windows on the screen, but you can also use command line options to do this. Note also that you can run xterm or other X clients without running a window manager. Titlebars are useful we’ll say more about them in the next section. (See Appendix A, System Management, for details.) When twm is started, you will see it add a titlebar to each window. It may also be started automatically from an. If xdm (the display manager) is starting X on your system, the twm window manager is probably started automatically when you log on. Starting the Window ManagerĪs described in Chapter 2, Getting Started, you start twm from the command line by typing: This chapter discusses each of these subjects in detail, but first we’ll take a look at starting twm.
