This class is based on article about Dynamic GUI Status & Tittle but was included directly into FALV and updated to keep the logic of it. in ZDEMO_FALV03 and ZDEMO_FALV04 you can find example of usage of fully and partly dynamic GUI. Bellow short description of some attributes and methods.
 
 

Constants

Please use this constants while adding, hiding, showing buttons in GUI Status. For fully dynamic GUI you can use all 35 slots, for partially dynamic version you can use up to 19 slots.

ADD_BUTTON

Use this method to add buttons to GUI STATUS in any place of the code. Changes are visible after next PBO event.
 
IV_BUTTON Button function code, please use one of constants B_xx.
IV_TEXT Optional - button text
IV_ICON Optional - button icon
IV_QINFO Optional - tooltip for button
IV_ALLOWED Optional - Button is enabled (in default abap_true)

    methods: add_button importing  value(iv_button)  type sy-ucomm
                                   value(iv_text)    type smp_dyntxt-text optional
                                   value(iv_icon)    type smp_dyntxt-icon_id optional
                                   value(iv_qinfo)   type smp_dyntxt-quickinfo optional
                                   value(iv_allowed) type abap_bool default abap_true
                        exceptions
                                   button_already_filled
                                   button_does_not_exists
                                   icon_and_text_empty.

HIDE_BUTTON

This method hides the button on GUI STATUS. Pass only button slot (constant B_xx to it).

    methods: hide_button importing value(iv_button) type sy-ucomm.

SHOW_BUTTON

If button was hidden using HIDE_BUTTON method or it was not allowed when adding to toolbar, then you can use SHOW_BUTTON method to make it visible. Pass only button slot (constant B_xx to it).

    methods: show_button importing value(iv_button) type sy-ucomm.

ADD_SEPARATOR

This method adds separator kind button to GUI status. In fact there is no possibility to add separator dynamically but we can pass button with empty text and icon, and this is what this method is doing.

    methods: add_separator importing  value(iv_button)  type sy-ucomm.

FULLY_DYNAMIC

This global variable determines if GUI Status is fully dynamic or not. On a base of it different GUI STATUSES are used in PBO of full screen FALV. Example of usage are in demo programs.

    data: fully_dynamic type abap_bool.

Layout class is based on the same principals like Column class. You will find here set methods for each layout field. Directly after calling layout methods, set_frontend Layout is called. Additionally layout class contains name of "mark field" if it was set. Like in Column class, you can use it before or after using display method.
 
 
Demo of the usage you can find in ZDEMO_FALV06.

Column class was created to be able modify faster the settings of field catalog at any place and time. Each field of field catalog has it set method with only one parameter IV_VALUE which type is equal to the field type. Additionally there are two methods set_editable and set_readonly which calls set_edit function with proper value. Example of usage you can find in ZDEMO_FALV07.
 
If you'll look into ZCL_FALV class then you'll see that you have direct access fcat table where all field catalog settings are store.  When you'll update this table before using display method then it would work as you expected but once you've displayed results and you modify fcat table then you need to use method set_frontend_fieldcatalog to affect grid object. That's why if you'll use Column object then this method is called directly.

The latest version of each part of FALV can be found on github repository https://github.com/fidley/falv which you can use in abapGit for easier up to date handling. 
 
You can call FALV also as popup. When you mark FALV as popup version then you can use default size or you can customize size. This demo shows how.

This demo uses few of previous demo examples + at the end it calls screen 0100 which has container CC_MAIN and they are used to create last FALV. So you have choice, you can use full screen FALV or you can place it in any container you want.

In standard ALV when you don't pass a container for a log then a popup with errors appears when you enter wrong data to cell. FALV allows you to use built-in split container which will show errors only when they appear and directly when the errors are gone, also container of errors is hidden. Check out the video.
