In this recipe, we will see how we can develop and configure Guided Activity Floorplan (GAF) applications. By default, one single step is automatically added to the component configuration. We will create one main step (step 2) that will comprise of one substep. We will write coding that will display the substep after the Next button of the step 2 is clicked. There is no ticket area for a GAF application.
In this recipe, we will focus on the steps relevant to GAF applications.
We create a component by the name ZST8_GAF that comprised of views and windows shown in the following screenshot for the steps and substep:
The defined application is based upon the component FPM_GAF_COMPONENT and interface view is FPM_WINDOW.
Follow these steps:
- Within the configuration editor, one main step already exists. In addition, two toolbar buttons, Previous and Next buttons also exist.
- Select the main step and in the Attributes UIBB: WINSTEP1 panel, assign the component and view as shown in following screenshot:
- Then add one more main step using the Add Main Step button on the right-hand side of the screen. Assign the component and view appropriate values (WINSTEP2).
- Then, select the Main Step 2, and add a substep using the Add Substep button. For the substep, enter the component and view name created earlier.
- Also on the attributes of the Next button of Main Step 2, enter
STEP2_NEXTin the Event ID field.
- Next, we will create a new toolbar button on the Substep2 1. We will press the button Add Toolbar Element. The dialog appears as shown in the following screenshot:
- Next, we need to know the substep variant parameter. Select the Substep variant node from the left-hand pane and then choose the menu Change and then click Substep Variant Parameters.
- Note the value from the pop up that appears and then press OK.
- Save and activate your configurations.
- Next, we will write the code for activating the substep. This code is written in the
PROCESS_EVENTmethod of the component controller. - We use a
CASEstatement to make sure our added code runs for the Next button click of theMAINSTEP_2. - We call the
CREATE_BY_IDmethod of theCL_FPM_EVENTclass in order to create an event object. - Next, the
SET_VALUEmethod is called in order to specify the event parameters. The method is called three times, for specifying the main step, the next active substep, and the substep variant having the valuesMAINSTEP_2, SUBSTEP_2_1andSUBSTEPVARIANT_1respectively. - Finally, we raise the event that we have created using the
RAISE_EVENTmethod. TheMY_EVENTobject is passed for the parameterIO_EVENT.
We created the GAF application configuration and component configuration. We created two main steps and one substep. By default, the substep is not active. We wrote the code for activating the substep at runtime. We also added a toolbar button Return to Main Step for returning from the substep to the main step.
Running the application configuration will display the GAF application. You may use the Next button to go to the next step.
