Detailed Description

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.

Member Function Documentation

void KCompletionBox::activated ( const TQString &  ) [signal]

Emitted when an item was selected, contains the text of the selected item.

bool KCompletionBox::activateOnSelect ( ) const
Returns:
true if selecting an item results in the emition of the selected signal.
Since:
3.4.1
TQRect KCompletionBox::calculateGeometry ( ) const [protected]

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/TQComboBox when used with one.

Definition at line 332 of file kcompletionbox.cpp.

TQString KCompletionBox::cancelledText ( ) const [slot]
Returns:
the text set via setCancelledText() or TQString::null.
void KCompletionBox::down ( ) [slot]

Moves the selection one line down or select the first item if nothing is selected yet.

Definition at line 381 of file kcompletionbox.cpp.

void KCompletionBox::end ( ) [slot]

Moves the selection down to the last item.

Definition at line 421 of file kcompletionbox.cpp.

bool KCompletionBox::eventFilter ( TQObject *  o,
TQEvent *  e 
) [protected, virtual]

Reimplemented from KListBox to get events from the viewport (to hide this widget on mouse-click, Escape-presses, etc.

Definition at line 108 of file kcompletionbox.cpp.

void KCompletionBox::hide ( ) [virtual, slot]

Re-implemented for internal reasons.

API is unaffected.

Definition at line 324 of file kcompletionbox.cpp.

void KCompletionBox::home ( ) [slot]

Moves the selection up to the first item.

Definition at line 416 of file kcompletionbox.cpp.

void KCompletionBox::insertItems ( const TQStringList &  items,
int  index = -1 
) [slot]

Inserts items into the box.

Does not clear the items before. index determines at which position items will be inserted. (defaults to appending them at the end)

Definition at line 468 of file kcompletionbox.cpp.

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

Default is false.

See also:
setTabHandling
TQStringList KCompletionBox::items ( ) const [slot]

Returns a list of all items currently in the box.

Definition at line 85 of file kcompletionbox.cpp.

void KCompletionBox::pageDown ( ) [slot]

Moves the selection one page down.

Definition at line 402 of file kcompletionbox.cpp.

void KCompletionBox::pageUp ( ) [slot]

Moves the selection one page up.

Definition at line 409 of file kcompletionbox.cpp.

void KCompletionBox::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.

Definition at line 250 of file kcompletionbox.cpp.

void KCompletionBox::setActivateOnSelect ( bool  state) [slot]

Set whether or not the selected signal should be emitted when an item is selected.

Parameters:
statefalse if the signal should not be emitted.

3.4.1

Definition at line 549 of file kcompletionbox.cpp.

void KCompletionBox::setCancelledText ( const TQString &  txt) [slot]

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 TQString& )
Parameters:
txtthe text to be emitted if the user cancels this box

Definition at line 436 of file kcompletionbox.cpp.

void KCompletionBox::setItems ( const TQStringList &  items) [slot]

Clears the box and inserts items.

Definition at line 477 of file kcompletionbox.cpp.

void KCompletionBox::setTabHandling ( bool  enable) [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.
