The Q3ListBoxItem class is the base class of all list box items. More...
#include <Q3ListBoxItem>
This class is part of the Qt 3 support library. It is provided to keep old source code working. We strongly advise against using it in new code. See Porting to Qt 4 for more information.
Inherited by: Q3ListBoxPixmap and Q3ListBoxText.

The Q3ListBoxItem class is the base class of all list box items.
This class is an abstract base class used for all list box items. If you need to insert customized items into a Q3ListBox you must inherit this class and reimplement paint(), height() and width().
See also Q3ListBox.
Constructs an empty list box item in the list box listbox.
Constructs an empty list box item in the list box listbox and inserts it after the item after or at the beginning if after is 0.
Destroys the list box item.
Use isCurrent() instead. Returns true if isCurrent() returns true.
Implement this function to return the height of your item. The lb parameter is the same as listBox() and is provided for convenience and compatibility.
The default implementation returns QApplication::globalStrut()'s height.
Returns true if the item is the current item; otherwise returns false.
See also Q3ListBox::currentItem(), Q3ListBox::item(), and isSelected().
Returns true if this item is selectable (the default); otherwise returns false.
See also setSelectable().
Returns true if the item is selected; otherwise returns false.
See also Q3ListBox::isSelected() and isCurrent().
Returns a pointer to the list box containing this item.
Returns the item that comes after this in the list box. If this is the last item, 0 is returned.
See also prev().
Implement this function to draw your item. The painter, p, is already open for painting.
See also height() and width().
Returns the pixmap associated with the item, or 0 if there isn't one.
The default implementation returns 0.
Returns the item which comes before this in the list box. If this is the first item, 0 is returned.
See also next().
Returns 0.
Make your derived classes return their own values for rtti(), and you can distinguish between listbox items. You should use values greater than 1000 preferably a large random number, to allow for extensions to this class.
Use isSelected() instead. Returns true if isSelected() returns true.
Defines whether the list box item is responsible for drawing itself in a highlighted state when being selected.
If b is false (the default), the list box will draw some default highlight indicator before calling paint().
See also isSelected() and paint().
If b is true (the default) then this item can be selected by the user; otherwise this item cannot be selected by the user.
See also isSelectable().
Sets the text of the Q3ListBoxItem to text. This text is also used for sorting. The text is not shown unless explicitly drawn in paint().
See also text().
Returns the text of the item. This text is also used for sorting.
See also setText().
Reimplement this function to return the width of your item. The lb parameter is the same as listBox() and is provided for convenience and compatibility.
The default implementation returns QApplication::globalStrut()'s width.
