CONTROLS - TYPE TABLEVIEW

Syntax

CONTROLS contrl TYPE TABLEVIEW USING SCREEN dynnr.

Effect

Declaration of a Table Control . If the type TABLEVIEW is entered inthe CONTROLS statement, a deep structure is created with the name of the control andthe type CXTAB_CO T!O" of the type #roup CXTAB. Durin# screen processin#, thecomponents of the structure contain the attributes of the table control. $sin# thisstructure you can read and edit the attributes of the rele%ant table control.

At the top le%el, the deep structure CXTAB_CO T!O" contains components for the#eneral attributes of the table control. The component CO"& is an internal table of thestructure CXTAB_CO"$' and contains the attributes of indi%idual columns. Thestructure CXTAB_CO"$' contains a structured component &C!(( , which hasthe same structure as screen and contains the attributes of the screen element of eachcolumn. )ith the e*ception of the component C$!!( T_"I (, all components ofthe structure CXTAB_CO T!O" can be set in the ABA+ pro#ram.

In dynnr , you must specify the number of a screen on which a table control with thename contrl is defined. or dynnr , you can specify a literal or a constant of thetype n and the len#th -. )hen a screen, in which a table control called contrl isdefined, is first called, the start %alues of certain components of the structure areobtained from the definition of the table control whose screen is specified afterthe USING addition.

• In a table control, you can scroll %ertically usin# a scroll bar if the component"I (& of the structure CXTAB_CO T!O" was set to the correct row number

before the +BO processin# of the table control. (%ery time you scroll with thescroll bar, the e%ent +AI is tri##ered with an empty function code and thecomponent TO+_"I ( of the structure CXTAB_CO T!O" is automaticallyset to the new topmost row before the time of +BO.

Exam &e

If a table control is defined on the screen with the number 4//, whose rows aredefined with reference to the database table &+ "I in the ABA+ Dictionary, thecorrespondin# pro#rammin# of the ABA+ pro#ram can loo as follows. In a +BOmodule !r !"r #t"$ , an internal table s!%l&#t"$ is filled with data from the database

table. The number of rows of s!%l&#t"$ is assi#ned to the component lines of thestructure %l&'(t#t"$ created usin# CONTROLS= this is done to acti%ate the scroll bar ofthe table control. In a +AI module )od&%y#t"$ , the row of the internal table is modifiedwhose table

ey matches that of the interface wor area s!%l& defined usin# TABLES . The +AImodule )od&%y#t"$ is called for e%ery displayed row of the table control. Thecorrespondin# screen flow lo#ic can be seen in the e*ample for "OO+ .
