class KCompletionBox |
|
A helper widget for "completion-widgets" (KLineEdit, KComboBox))
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 or CompletionPopupAuto.

|
Emitted when an item was selected, contains the text of the selected item. |
|
This calculates the size of the dropdown and the relative position of the top left corner with respect to the parent widget. This matches the geometry and position normally used by K/QComboBox when used with one. |
|
Returns the text set via setCancelledText() or QString(). |
|
Moves the selection one line down or select the first item if nothing is selected yet. |
|
Moves the selection down to the last item. |
|
Reimplemented from KListWidget to get events from the viewport (to hide this widget on mouse-click, Escape-presses, etc. |
|
The preferred global coordinate at which the completion box's top left corner should be positioned. |
|
Moves the selection up to the first item. |

|
Moves the selection one page down. |
|
Moves the selection one page up. |
|
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. |
|
Set whether or not the selected signal should be emitted when an
item is selected. By default the selected() signal is emitted.
state - false if the signal should not be emitted. |
|
Sets the text to be emitted if the user chooses not to
pick from the available matches.
If the canceled text is not set through this function, the userCancelled signal will not be emitted. See also userCancelled( const QString& ) txt - the text to be emitted if the user cancels this box |
|
Clears the box and inserts items. |
|
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. See also isTabHandling |
|
Re-implemented for internal reasons. API is unaffected. |
