Exercise - Exporting the Traffic Cone Component

Preliminaries

• Create a traffic cone component as shown in the exercise Building a Complex Component - the traffic cone.

Declaring the interface

Before you export a component, you need to 'declare the interface'.

• Move the mouse cursor over the System Panel, and right-click.

• Select the option 'Export component'. The Component Management dialogue box opens.

• Configure this for the traffic cone component as follow:

• Click on the 'Setup' tab.

• Assign the component to the 'Misc'toolbox, by clicking on the down-arrow next to the label 'Category'.
• Click on the check-box next to the 'Use an image of the panel' label.

• Click on the 'Interface' tab.

• Set the 'LEDoff' and 'LEDon' macros as 'Component' macros, by selecting each in turn, and clicking on 'Component macro' in the 'Type of macro' drop-down menu.
• Set the 'PinChange' macro as a 'Hidden' macro, in the same way.

• In this case, there is no need to use the 'Resources' tab, as there are no additional files to save with the component.

• Click on 'OK'.

Saving the component

• You may be asked if you want to save the current flowchart. Do so if you wish.

• The 'Save As' dialogue box opens. This will automatically point to a destination Flowcode will search for components. Select a suitable name for the component.

• Click 'Save'. The component file is saved with a '*.fcpx' extension.

Testing the component

Go to the category your component was assigned to be in, ('Outputs' in this case). If you did not select a category you will find the component inMisc.

Click on the down arrow next to the component, and select 'Add to system panel, or double click on the name of the component.

Create a Flowcode flowchart to test the component, such as the one given in the Exercise - Testing an imported LED component
