User interface basics
This chapter explains the notation conventions used in this manual and the
basics of the user interface manipulation. If you are familiar with the
Motif interface, you may want to skip the rest of this chapter. The descrip-
tion of the interface given here is not intended to be complete, but rather
to give enough of information to let a novice user to operate the program.
For more information about the general manipulation of the operating sys-
tem interface, refer to “User’s Guide” of Common Desktop Environment.
1.1 Using menus
On the top of the main window of the program lies a horizontal bar con-
taining so called menus. Each one is represented by its name. When the
name is clicked with the mouse button 1 (usually the leftmost button), a
stack of buttons appears. This stack of buttons is called a menu. You can
initiate different kinds of operations by clicking corresponding button in a
menu. When a button within the menu is pressed, and the mouse button is
released, the corresponding action will be executed, and the menu disap-
pears.
You may also activate a menu button by pressing the mouse button on the
name of the menu, holding the button down and dragging it on top of the
desired button. The action is now executed when the button is released on
the menu item. If you pop up a menu accidentally, you can cancel the
operation by releasing the mouse button when cursor is outside the menu,
or if you clicked the name, by clicking somewhere outside the menu.
Some menus contain so called submenus. They are connected to menu
buttons whose activation pops up yet another menu. The submenu itself is
used just similar fashion as a normal menu. Submenus are denoted by a
small triangle on the left edge of a menu button.
1.2 Using text fields
Several user interface elements use so called text fields, or text boxes.
This is a rectangle that contains some editable text inside.
