In this recipe, we will see how we can change the IDR header (title and ticket area) programmatically. In this case, the previously statically defined (through IDR configuration) ticket area and title are overridden. This concept applies to both the OIF and OVP Floorplans.
In this recipe, we will write the code for changing within the view (window) shown within a subview. When the particular subview is selected, the header title and ticket area will change. We will write the code in the component whose view is used as an UIBB in a subview. We will write the code in the respective view (WDDOINIT method).
For dynamically changing the IDR title and ticket area, proceed as follows:
- First, we define an attribute at the component controller level by the name
MY_FPM_IDRbased on the typeIF_FPM_IDR.
- Next, we define a
SET_IDR_TITLE_TICKETmethod in the component controller. Then, we will write the coding in the method. We first define a reference variableMY_FPMthat point to the interfaceIF_FPM. We call the static methodGET_INSTANCEof theCL_FPM_FACTORYclass in order to create a reference to the FPM service object.
- We then call the
GET_SERVICEmethod with the constant attributeGC_KEY_IDRof the classCL_FPM_SERVICE_MANAGER. The result of the method is then assigned toMY_FPM_IDRattribute we defined in the first step.
- We then call the
SET_APPLICATION_TITLEmethod of the attributeMY_FPM_IDR. We pass theNew TitleandNew Tooltipparameters for the IDR.
- We then call the
SET_TICKETmethod for the referenceMY_FPM_IDR. The necessaryTicket topandTicket bottomtexts are passed as values corresponding to necessary parameters.
- We then need to write the code for calling the method
SET_IDR_TITLE_TICKETfrom theWDDOINITmethod of the view that is used in the UIBB of the subview.
By following these steps, we are accessing the IDR at runtime and specifying its displayed IDR title and ticket area text.
We created a method SET_IDR_TITLE_TICKET at the component controller level that access the service object for accessing the IDR. Appropriate methods are called in order to set the application title, ticket top, and bottom. Next, this method is called from the WDDOINIT method of the view used in the UIBB of our OIF application.
When the application is run and the relevant subview is selected, the WDDOINIT method is called that calls the SET_IDR_TITLE_TICKET method of the component controller. The New Title, Ticket top, and Ticket bottom parameters are changed as shown in following screenshot:
