	@doc: listviewitem
	@keyterms:
		listview listviewitem class
	@title:
		listviewitem class
	@type:
		class
	@short:
		A listviewitem class
	@inherits:
		[class]listviewitem[/class]
	@description:
		The listviewitem class implements a list view item.
		A list view item is a multi-column object capable of displaying itself in a [class]listview[/class].
		To use this class you must instantiate it with another listviewitem or a [class]listview[/class]
		as parent. The item will be automatically displayed.
		You can set the text and a pixmap in each column and you can make it checkable
		with [classfnc:listviewitem]$setCheckable[/classfnc]().
		A checkable listviewitem will display a small check mark in the first column.
	@functions:
		!fn: $setText(<column:integer>,<text:string>)
		Sets the text in column column to text, if column is a valid column number and text is different from the existing text.

		!fn: <string> $text(<column:integer>)
		Returs the text of the specified column.

		!fn: $setPixmap(<column:integer>,<pixmap:hobject or imageID>)
		Sets the pixmap in column column to pm, if pm is non-null and different from the current pixmap, and if column is non-negative.
		Pixmap can be a Kvirc imageid, an image file or a [class]pixmap[/class] object.

		!fn: $setRenameEnabled(<col:integer>,<bEnabled:boolean>)
		If b is TRUE (1), this item can be in-place renamed in the column col by the user; otherwise it cannot be renamed in-place.

		!fn: $setEnabled(<bEnabled:boolean>)
		Enables or disables the item

		!fn: $isEnabled()
		Returns $true if this item is enabled and $false otherwise

		!fn: $setOpen(<bOpen:boolean>)
		Opens or closes the item to show its children items

		!fn: $isOpen()
		Returns the open state of this item

		!fn: $setCheckable(<bCheckable:boolean>)
		Makes this item checkable or not. This function should be called immediately
		after the item creation: changing this property later at runtime may have
		strange results (like the item being moved inside the list, text disappearing,
		hidden children etc... don't do it :D ).

		!fn: $isCheckable()
		Returns $true if this item is checkable and $false otherwise

		!fn: $setChecked(<bChecked:boolean>)
		Sets this item to be checked or not. [classfnc:listviewitem]$setCheckable[/classfnc]() must
		have been previously called.

		!fn: $isChecked()
		Returns the check status of this item. [classfnc:listviewitem]$setCheckable[/classfnc]() must
		have been previously called.

		!fn: <listviewitem> $firstChild()
		Returns the first child item of this listviewitem or $null if this item has no children.

		!fn: <listviewitem> $nextSibling()
		Returns the next sibling item of this listviewitem or $null if there are no sibling items.
		Next sibling stands for the item at the same tree level coming just after :)
