| Summary | 0003947: Feature - Adding Bit-List to JvCheckedComboBox | ||||
| Description | In several applications I have developed, I am using a Bit-Map (Longint) to Store/Show the selected elements.. My wish is that this can be added to the TJvCheckedComboBox. Another possible enhancement (maybe) is to sort the sequence of selected Items as they are displayed. | ||||
| Additional Information | Enclosed sample display program to show this feature.. In this example, I am using a loop to select/show the bits.. Another possibility is to use the BitSelect library as shown by Glen Crouch (ESB Consultancy). | ||||

Bit maps are not user friendly, are error prone and can lead to serious problems when used without prior knowledge. The better way to do this is to use "set of" types for properties, which internally are stored as bit maps. Furthermore, deciding which elements to show/hide is the responsibility of the user, not the combobox. What is the point of putting elements in the list if they are not to be shown? |

This proposal is by no means acceptable for the JVCL. |
