A little utility class for "completion-widgets", like KLineEdit or KComboBox. KCompletionBox is a listbox, displayed as a rectangle without any window-decoration, usually directly under the lineedit or combobox. It is filled with all possible matches for a completion, so the user can select the one he wants.
It is used when KGlobalSettings::Completion == CompletionPopup.
| KCompletionBox ( QWidget *parent, const char *name = 0 )
| KCompletionBox |
Constructs a KCompletionBox.
Notice: the parent needs to be always 0L, so you can't specify it in the constructor. Because of that, Qt's auto-deletion does not take place, so you have to explicitly delete this widget when you don't need it anymore.
The parent widget is used to give the focus back when pressing the up-button on the very first item.
| ~KCompletionBox ()
| ~KCompletionBox |
Destroys the box
| QSize sizeHint ()
| sizeHint |
[const virtual]
Reimplemented from QListBox.
| QStringList items ()
| items |
[const slot]
Returns: a list of all items currently in the box.
| void popup ()
| popup |
[virtual slot]
Adjusts the size of the box to fit the width of the parent given in the constructor and pops it up at the most appropriate place, relative to the parent.
Depending on the screensize and the position of the parent, this may be a different place, however the default is to pop it up and the lower left corner of the parent.
Make sure to hide() the box when appropriate.
| void setTabHandling ( bool enable )
| setTabHandling |
[slot]
Makes this widget (when visible) capture Tab-key events to traverse the items in the dropdown list.
Default off, as it conflicts with the usual behavior of Tab to traverse widgets. It is useful for cases like Konqueror's Location Bar, though.

| bool isTabHandling ()
| isTabHandling |
[const slot]
Default is false.
Returns: true if this widget is handling Tab-key events to traverse the items in the dropdown list, otherwise false.

| void setCancelledText ( const QString& )
