At execution of some applications functions (for example, terminating the text Editor,
Musical Editor, Graphics Editor etc.) it is necessary to load the dialog box without closing the current application
screen. The dialog box is visually located at the top of the current application screen or a Navigation
interface structure.
The dialog box consists of the operations Text. It is necessary for fulfilling the
current stage of an applications operation. The dialog box also consists of several operations controls, for
example, confirmation of operation, cancellation of operation, or cancellation of the dialog box.
The operations text is always centered at the middle of the area and is placed
between the dialog box boundaries and the nearest operations control boundaries. The operations text font is
the standard font. Subdividing the text is permitted. Operations controls are located either across the bottom
of the dialog box or on a vertical in the left part of the dialog box.
Control size is a maximum of 1/3 of the width of the dialog box. Controls are placed at
equal distances horizontally between the dialog box boundaries. The control size is dictated by the size of the
dialog box. Subdividing the text is allowed in the controls area. The control size on a vertical is dictated by
the font size (plus 2 pixels from above and from below up to the controls boundary).
In the initial state the focal point is on the control that confirms an operation.
Keyboard layout by operation with dialog boxes is as follows:
Key <TAB> is used to switch between controls in a clockwise circle.
Keys <LEFT ARROW> and <RIGHT ARROW> are similar to <TAB> key.
Key <ENTER> is used to execute the current control function.
