2.6. Input help - Input help

Input help is a feature, which allows supporting the user when entering text. Significant activation strings are used in order to pop up with a selection list, which offers possible choices for the next item. Usually, input help is provided for large text fields. Typically, input help is used in programming environment in order to support programmers e.g. with appropriate function lists.

Usually, several input help controls are provided in order to support different types of lexical items. Selection lists for input help can be provided calling addInputHelp() . By passing class and control name for the selection list and a number of activation strings, selection controls will be created which are selected by input sequences (e.g. typing a dot may cause displaying a member list for the currently selected class, typing an open parenthesis may cause displaying a list of possible parameters).

After creating input help controls input help need to be activated in order to react on activation patterns ( inputHelpActivated( true ) ). Input help might be disabled temporarily and input help controls might be removed ( removeInputHelp() )
