Interactive Options

The following sections discuss the Windows operating environment considerations.

NOTE: Niakwa strongly recommends using only the Windows version of the RunTime on any system using Microsoft Windows (any variant).

The Windows RunTime Program can be executed by a variety of methods. It can be started from the Windows Program Manager or from a command line using the Windows RUN program feature. Please refer to the instructions provided by your Authorized Niakwa Distributor on how to execute this RunTime with the application.

When using the Windows version of the RunTime, a user can have multiple tasks running on a specific workstation with the user count adjusted by only one user. For the standard network RunTime, the user count is adjusted by one, each time a standard RunTime is executed.

The RunTime provides five user-selectable options from the Option Menu accessible from the RunTime Menu Bar. These options are: Browse Keys, SF Keys, Follow, Autosize and Debug.

To activate any of these options it is necessary to "check" it. To do this, first select the Option Menu from the menu bar (the Option Menu displays the five interactive options). To check an item, select the desired option by clicking with the mouse. When an option is selected, a check mark appears next to the item to show that it is active. To deactivate an option, select it again and the check mark is removed.

Any or all these options can be used simultaneously. The following sections describe these options in detail.

Browse Keys

This option allows the Niakwa Virtual Keys to be accessed directly from the screen using a mouse. When this option is active, a window box appears on the screen with the names of the Niakwa keys that currently can be accessed with a mouse.

The default keys used are: Cancel, Prev, Insert, Exec, TAB, Next, Delete, Back, Space, Return, and the North, South, East and West directional keys as shown below.

NOTE: These key labels may have been changed by the application developer.

To move the Browse Key window to another position on the desktop, use the mouse to drag the window to the new location as if it were any other window. If the associated parent task for the Browse Key window is minimized, the Browse Key display is not visible as long as the task remains minimized.

NOTE: The status (active or not active) and the last location of the Browse Key window, before the RunTime task is closed, is automatically stored.

Special Function Keys

The Special Function (SF) Keys option allows the operator to select the Niakwa SF Keys from a window box, as shown below, with the use of a mouse.

When this option is selected a window box displays the SF Keys 0-15 on the screen in a window. The SF Keys may appear as a single row as shown above or as two rows, as shown below, depending on the application setup.

NOTE: These key labels may have been changed by the application developer.

Keys are selected by locating the mouse cursor to the desired key and clicking the primary (left) button. SF Keys 16-31 can be accessed through this option by holding the secondary (right) mouse button and clicking the primary (left) button when the pointer is on the appropriate SF Key. For example, to generate the SF Key 17 using a right-handed mouse, press and hold the right mouse button and click the left button when over the SF Key 1.

To move the SF Keys window to another position on the desktop, use the mouse to drag the window to the new location as if it were any other window. If the associated parent task for the SF Keys window is minimized, the SF Key display is not visible as long as the task remains minimized.

NOTE: The status (active or not active) and the last location of the SF Key window, before the RunTime task is closed, is automatically stored.

Follow

In cases where the visible window is too small to display the entire RunTime screen, the Follow option keeps the cursor visible in the RunTime task window. When this option is active, the window automatically scrolls to keep the cursor visible when awaiting input. When switched off, the cursor can move off the visible screen area displayed on the window to other parts of the full screen display.

The status of this option is saved by the RunTime when the current task is closed. The next time the RunTime task is started it uses the saved status as its default.

Autosize

When this option is selected, the Windows RunTime selects the closest available font to fit a full screen (24 rows x 80 or 132 columns) into the current window size. Scroll bars appear if the window size and font size combination do not allow the full Niakwa screen to appear in the resized window. When the option is not selected, changing the size of the window does not affect the font size.

NOTE: This option requires use of the Niakwa BASFONTS.FON font file or equivalent.

HINT: Select the Autosize option and resize the window until a comfortable font size is displayed. This font size then can be saved by switching the Autosize option to off. When switched off, the font size does not change even if the window is resized.

The status of this option is saved by the RunTime when the current task is closed. The next time the RunTime task is started, the saved status of the options is used as the default values.

Debug

This option is provided for application development. Contact your Authorized Niakwa Distributor for details.
