/**
|
| 64 |
* This class allows users to insert a chain of characters and show all the sentences of the JComboBox that match its first ones characters with it.
|
| 65 |
* This class is also a Java Bean.
|
| 66 |
* The behavior of this componet can be configurated by 6 flags:
|
| 67 |
* + The appearence of the items showed at the beginning and when the user presses the ESCAPE key: (This is configured with 2 flags -> 3 different states are possible)
|
| 68 |
* -> maintainPositionItems -> When we see the list of all items, this are showed in the ordenation as they have been introduced (if true); (if false) each new item
|
| 69 |
* when we write on the TextField of this Component will be showed at the end
|
| 70 |
* -> all_Alphanumeric_Sorted -> All items we can see in this Component will be showed in alphanumeric ordenation (if true)
|
| 71 |
* + The list of the items showed when the user makes a search writting or pressing the BACK-SPACE key (This is configured with 1 flag -> 2 different states are possible)
|
| 72 |
* -> alphanumericSortedSearches -> When we write on the TextField of this Component all results (items) are showed in alphanumeric ordenation (if true)
|
| 73 |
* + Key Sensitive or not when the user writes
|
| 74 |
* -> key_Sensitive -> When we write on the TextField it can discriminate upper cases from down cases (if true) or not (if false) (This is configured with 1 flag -> 2 different states are possible)
|
| 75 |
* + Use one color (black) or 2 colors (black by default and red if the string written doesn't match with the beginning of all items)
|
| 76 |
* -> only_One_Color -> The text on the textField only will be showed on black color (if true); false -> if the text on the textField doesn't match with any current item of this component -> the text
|
| 77 |
* will be showed on red color
|
| 78 |
* + Show all items always
|
| 79 |
* -> showAllItems -> If true -> this component shows all items always; if false -> this component only shows items that their first characters match with the string written by the user
|
| 80 |
*
|
| 81 |
* Default Values of the Flags:
|
| 82 |
* -> maintainPositionItems -> true
|
| 83 |
* -> all_Alphanumeric_Sorted -> true
|
| 84 |
* -> alphanumericSortedSearches -> false
|
| 85 |
* -> key_Sensitive -> false
|
| 86 |
* -> only_One_Color -> false
|
| 87 |
* -> showAllItems -> false
|
| 88 |
*
|
| 89 |
* Combinations of flags not allowed:
|
| 90 |
* -> maintainPositionItems == allAlphanumericSorted == true
|
| 91 |
* -> ((maintain_Position_Items == false) && (all_Alphanumeric_Sorted == true) && (alphanumeric_Sorted_Searches == false))
|
| 92 |
* -> showAllItems == true && maintainPositionItems == false
|
| 93 |
*
|
| 94 |
* Limitations:
|
| 95 |
* -> When we add more than one item with the same name (string value) -> the behavior of this component only considers one item in most of the cases when it does a search
|
| 96 |
* -> If this component has Hundreds,Thousands or even Million/s of items is probably that had quite delay to respond the evens of the user; this also depends of the machine where it's executed
|
