Using Modules

Launching a Module

To load a module into the Map Editor (Launch it), the following steps must be taken.

  • Locate the category in the Module Librarian containing the module using the scroll bar (if necessary). Note that the Modules category contains all the supported modules in the default installation and many of these modules also appear in other categories.
  • Expand the selected category by clicking on the "+" sign by its name or double-clicking its name or icon.
  • Select the module by either clicking on its label, typing its name (the list will scroll to the first object whose name starts with the characters typed), or using the arrow keys on the keyboard.
  • Launch the module by either dragging the module (by holding down the left-hand mouse button) and dropping it over its desired location in the Map Editor or clicking with the right-hand mouse button and selecting "Launch".

Once this has been done, the Module will start up, and its Control Panel (similar to the example below) will appear in the Map Editor.

Working with Modules in the Map Editor

To use most of the operations associated with a module it must be selected. Modules can be selected by clicking the left-hand mouse button on the title bar. To deselect a module, press the left-hand mouse button on the background of the Map Editor.

It is possible to select multiple modules either by holding down the "shift" key and selecting additional modules (note: select the first module in the normal way) or by moving the mouse with the left-hand mouse button pressed to enclose the modules to be selected in a box.

The module title bar changes from grey to white when the module is selected. To move selected module(s), hold the left-hand mouse button down, and drag the mouse to move the module(s) around in the Map Editor.

Each module has a help file associated with it that you can use to find out how the module works. To access this help file, click the right-hand mouse button on the module title (or its label in the Module Librarian) and select Help from the menu.

The Module Control Panel

The module control panel is available in two forms. The default form (shown above) is known as the minimised or mini control panel. The maximised or maxi control panel enables users to control the behaviour of the module (see Maximising the Module Control Panel below).

The minimised module control panel contains

  • Title bar
  • Sizing button
  • Input port access pad
  • Output port access pad

Maximising the Module Control Panel

Each module has a Control Panel. This is a small point-and-click interface that enables control of the properties of the module. To open the control panel, click on the sizing button with the left-hand mouse button. It can be closed in the normal way: by clicking with the left-hand mouse button on the "close" button in the top right-hand corner of the window.
