Overview

A List Widget displays a list of items, each with a text and optional icon. When an item's selected state changes, the list sends a SEL_SELECTED or SEL_DESELECTED message. A change of the current item is signified by the SEL_CHANGED message. The list sends SEL_COMMAND messages when the user clicks on an item, and SEL_CLICKED, SEL_DOUBLECLICKED, and SEL_TRIPLECLICKED when the user clicks once, twice, or thrice, respectively. When items are added, replaced, or removed, the list sends messages of the type SEL_INSERTED, SEL_REPLACED, or SEL_DELETED. In each of these cases, the index to the item, if any, is passed in the 3rd argument of the message.

Events

The following messages are sent by FXList to its target:

SEL_CHANGED

sent when the current list item changes; the message data is an Integer indicating the index of the current item.

SEL_COMMAND

sent when the current list item changes; the message data is an Integer indicating the index of the current item.

SEL_KEYPRESS

sent when a key goes down; the message data is an FXEvent instance.

SEL_KEYRELEASE

sent when a key goes up; the message data is an FXEvent instance.

SEL_LEFTBUTTONPRESS

sent when the left mouse button goes down; the message data is an FXEvent instance.

SEL_LEFTBUTTONRELEASE

sent when the left mouse button goes up; the message data is an FXEvent instance.

SEL_RIGHTBUTTONPRESS

sent when the right mouse button goes down; the message data is an FXEvent instance.

SEL_RIGHTBUTTONRELEASE

sent when the right mouse button goes up; the message data is an FXEvent instance.

SEL_CLICKED

sent when a list item is single-clicked; the message data is an Integer indicating the index of the current item.

SEL_DOUBLECLICKED

sent when a list item is double-clicked; the message data is an Integer indicating the index of the current item.

SEL_TRIPLECLICKED

sent when a list item is triple-clicked; the message data is an Integer indicating the index of the current item.

SEL_SELECTED

sent when a list item is selected; the message data is an Integer indicating the index of the selected item.

SEL_DESELECTED

sent when a list item is deselected; the message data is an Integer indicating the index of the deselected item.

SEL_REPLACED

sent when a list item is about to be replaced; the message data is an Integer indicating the index of the item to be replaced.

Instance Method Details

#appendItem(text, icon = nil, data = nil, notify = false) ⇒ Object

Append a new item with given text and optional icon and user data, e.g.

list.appendItem("pinky")

If notify is true, a SEL_INSERTED message is sent to the list's message target after the item is appended. Returns the integer index of the newly appended item.


209
# File 'rdoc-sources/FXList.rb', line 209

def clearItems(notify=false) ; end

#deselectItem(index, notify = false) ⇒ Object

def deselectItem(index, notify=false) ; end

#disableItem(index) ⇒ Object

Disable item. Raises IndexError if index is out of bounds.

end

#enableItem(index) ⇒ Object

398
# File 'rdoc-sources/FXList.rb', line 398

def enableItem(index) ; end

#extendSelection(index, notify = false) ⇒ Object

Extend selection from anchor item to index. If notify is true, a series of SEL_SELECTED and SEL_DESELECTED messages are sent to the list's message target as the selected-state of different items changes. Raises IndexError if index is out of bounds.


433
# File 'rdoc-sources/FXList.rb', line 433

def extendSelection(index, notify=false) ; end

#extractItem(index, notify = false) ⇒ Object

Extract item from list and return a reference to the item. If notify is true, a SEL_DELETED message is sent to the list's message target before the item is extracted from the list. 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 name. Return -1 if no matching item is found.


291
# File 'rdoc-sources/FXList.rb', line 291

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. Returns the integer index of the matching item, or -1 if no match is found. 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.

def killSelection(notify=false) ; end

#makeItemVisible(itemOrIndex) ⇒ Object

def makeItemVisible(itemOrIndex) ; end

#moveItem(newIndex, oldIndex, notify = false) ⇒ Object

Move item from oldIndex to newIndex and return the new index of the item.. If notify is true and this move causes the current item to change, a SEL_CHANGED message is sent to the list's message target to indicate this change in the current item.

# File 'rdoc-sources/FXList.rb', line 409

def selectItem(index, notify=false) ; end

#setCurrentItem(index, notify = false) ⇒ Object

Change current item. If notify is true, a SEL_CHANGED message is sent to the list's message target after the current item changes. Raises IndexError if index is out of bounds.
