SET LIST ITEM PROPERTIES
SET LIST ITEM PROPERTIES
The SET LIST ITEM PROPERTIES command modifies the item designated by the itemRef parameter within the list whose reference number or object name is passed in list. If you pass the first optional * parameter, you indicate that the list parameter is an object name (string) corresponding to a representation of the list in the form. If you do not pass this parameter, you indicate that the list parameter is a hierarchical list reference (ListRef). If you only use a single representation of the list or work with structural items (the second * is omitted), you can use either syntax. Conversely, if you use several representations of the same list and work with the current item (the second * is passed), the syntax based on the object name is required since each representation can have its own current item. You can pass a reference number in itemRef. If there is no item with the item reference number that is passed, the command does nothing. You can optionally pass 0 in itemRef to modify the last item added to the list using APPEND TO LIST. Lastly, you can pass * in itemRef: in this case, the command will apply to the current item of the list. If several items are selected manually, the current item is the one that was selected last. If no item is selected, the command does nothing. If you work with item reference numbers, build a list in which items have unique reference numbers, otherwise you will not be able to distinguish the items. For more information, refer to the Managing Hierarchical Lists section. Note: To change the text of the item or its sublist, use the command SET LIST ITEM. To make an item enterable, pass TRUE in enterable; otherwise, pass FALSE. Important: In order for an item to be enterable, it must belong to a list that is enterable. To make a whole list enterable, use the OBJECT SET ENTERABLE command. To make an individual list item enterable, use SET LIST ITEM PROPERTIES. Changing the enterable property at the list level does not affect the enterable properties of the items. However, an item can be enterable only if its list is enterable.You specify the font style of the item in the styles parameter. You pass a combination (one or a sum) of the following predefined constants (Font Styles theme):
To associate an icon to the item, pass Use PicRef+N in the icon parameter, where N is the reference number of a picture from the Design environment Picture Library. Pass zero (0), if you do not want any graphic for the item. Notes:
The color parameter (optional) lets you modify the color of the item text. The color must be specified in the form of an RGB color, i.e. a 4-byte longint in the 0x00RRGGBB format. For more information about this format, refer to the description of the OBJECT SET RGB COLORS command. Pass -1 in the color parameter to reset the original color of the item. See the example for the APPEND TO LIST command.
