Overview

The List Box is a control to select one of a list of options. It looks similar to a Combo Box except that List Box yields integer numbers only. When an option is selected, List Box will send an SEL_COMMAND with the index of the opton. While manipulating the list, it may send SEL_CHANGED messages to indicate which option the cursor is hovering over. The List Box is able to receive ID_GETINTVALUE and ID_SETINTVALUE which will retrieve the current option or change the selected option.

Events

The following messages are sent by FXListBox to its target:

SEL_COMMAND

sent when a new list item is clicked; the message data is the index of the selected item.

SEL_CHANGED

sent when a new list item is clicked.

#extractItem(index) ⇒ Object

Extract item from list and return a reference to the item. Raises IndexError if index is out of bounds.

#findItem(text, start = -1,, flags = SEARCH_FORWARD|SEARCH_WRAP) ⇒ Object

Search items by text, beginning from item start. If the start item is -1 the search will start at the first item in the list. Flags may be SEARCH_FORWARD or SEARCH_BACKWARD to control the search direction; this can be combined with SEARCH_NOWRAP or SEARCH_WRAP to control whether the search wraps at the start or end of the list. The option SEARCH_IGNORECASE causes a case-insensitive match. Finally, passing SEARCH_PREFIX causes searching for a prefix of the item text. Return -1 if no matching item is found.

# File 'rdoc-sources/FXListBox.rb', line 136

def findItem(text, start=-1, flags=SEARCH_FORWARD|SEARCH_WRAP); end

#findItemByData(data, start = -1,, flags = SEARCH_FORWARD|SEARCH_WRAP) ⇒ Object

Search items by associated user data, beginning from item start. If the start item is -1 the search will start at the first item in the list. Flags may be SEARCH_FORWARD or SEARCH_BACKWARD to control the search direction; this can be combined with SEARCH_NOWRAP or SEARCH_WRAP to control whether the search wraps at the start or end of the list.
