A combo box with completion support.
This widget inherits from QComboBox and implements the following additional features:
- a completion object that provides both automatic and manual text completion as well as text rotation
- configurable key bindings to activate these features
- a popup menu item that can be used to allow the user to change the text completion mode on the fly.
To support these additional features, KComboBox emits a few additional signals such as completion(const QString&) and textRotation(KeyBindingType).
The completion signal can be connected to a slot that will assist the user in filling out the remaining text while the rotation signal can be used to traverse through all possible matches whenever text completion results in multiple matches. Additionally, the returnPressed(const QString &) signal is emitted when the user presses the Return or Enter key.
KCombobox by default creates a completion object when you invoke the completionObject(bool) member function for the first time or explicitly use setCompletionObject(KCompletion*, bool) to assign your own completion object. Additionally, to make this widget more functional, KComboBox will by default handle text rotation and completion events internally whenever a completion object is created through either one of the methods mentioned above. If you do not need this functionality, simply use KCompletionBase::setHandleSignals(bool) or alternatively set the boolean parameter in the setCompletionObject()
call to false
.
Beware: The completion object can be deleted on you, especially if a call such as setEditable(false) is made. Store the pointer at your own risk, and consider using QPointer<KCompletion>.
The default key bindings for completion and rotation are determined from the global settings in KStandardShortcut. These values, however, can be overridden locally by invoking KCompletionBase::setKeyBinding(). The values can easily be reverted back to the default settings by calling useGlobalSettings(). An alternate method would be to default individual key bindings by using setKeyBinding() with the default second argument.
A non-editable combo box only has one completion mode, CompletionAuto
. Unlike an editable combo box, the CompletionAuto mode works by matching any typed key with the first letter of entries in the combo box. Please note that if you call setEditable(false) to change an editable combo box to a non-editable one, the text completion object associated with the combo box will no longer exist unless you created the completion object yourself and assigned it to this widget or you called setAutoDeleteCompletionObject(false). In other words do not do the following:
A read-only KComboBox will have the same background color as a disabled KComboBox, but its foreground color will be the one used for the editable mode. This differs from QComboBox's implementation and is done to give visual distinction between the three different modes: disabled, read-only, and editable.
Usage
To enable the basic completion feature:

at position index
into the combo box.
QUrl::toDisplayString() is used so that the url is properly decoded for displaying.
Definition at line 182 of file kcombobox.cpp.
◆ makeCompletion
|
protectedvirtualslot |
Completes text according to the completion mode.
- Note
- This method is not invoked if the completion mode is set to
CompletionNone
. Also if the mode is set toCompletionShell
and multiple matches are found, this method will complete the text to the first match with a beep to indicate that there are more matches. Then any successive completion key event iterates through the remaining matches. This way the rotation functionality is left to iterate through the list as usual.
Definition at line 125 of file kcombobox.cpp.
◆ minimumSizeHint()
|
overridevirtual |
Reimplemented from QComboBox.
Definition at line 220 of file kcombobox.cpp.
◆ returnPressed
|
signal |
Emitted when the user presses the Return or Enter key.
The argument is the current text being edited.
- Note
- This signal is only emitted when the widget is editable.
◆ rotateText
|
slot |
Iterates through all possible matches of the completed text or the history list.
Depending on the value of the argument, this function either iterates through the history list of this widget or all the possible matches in whenever multiple matches result from a text completion request. Note that the all-possible-match iteration will not work if there are no previous matches, i.e. no text has been completed and the *nix shell history list rotation is only available if the insertion policy for this widget is set either QComobBox::AtTop
or QComboBox::AtBottom
. For other insertion modes whatever has been typed by the user when the rotation event was initiated will be lost.
- Parameters
-
type The key binding invoked.
Definition at line 141 of file kcombobox.cpp.
◆ setAutoCompletion()
|
virtual |
Reimplemented from QComboBox.
If true
, the completion mode will be set to automatic. Otherwise, it is defaulted to the global setting. This method has been replaced by the more comprehensive setCompletionMode().
- Parameters
-
autocomplete Flag to enable/disable automatic completion mode.
Definition at line 84 of file kcombobox.cpp.
◆ setCompletedItems
|
overrideslot |
Sets items
into the completion box if completionMode() is CompletionPopup.
The popup will be shown immediately.
Definition at line 203 of file kcombobox.cpp.
◆ setCompletedText [1/2]
|
overrideslot |
Sets the completed text in the line edit appropriately.
This function is an implementation for KCompletionBase::setCompletedText.
Definition at line 117 of file kcombobox.cpp.
◆ setCompletedText() [2/2]
|
protectedvirtual |
This function sets the line edit text and highlights the text appropriately if the boolean value is set to true.
- Parameters
-
text The text to be set in the line edit marked Whether the text inserted should be highlighted
Definition at line 109 of file kcombobox.cpp.
◆ setCurrentItem
|
slot |
Selects the first item that matches item
.
If there is no such item, it is inserted at position index
if insert
is true. Otherwise, no item is selected.
Definition at line 305 of file kcombobox.cpp.
◆ setEditable()
void KComboBox::setEditable | ( | bool | editable | ) |
Reimplemented so that setEditable(true) creates a KLineEdit instead of QLineEdit.
Note that QComboBox::setEditable is not virtual, so do not use a KComboBox in a QComboBox pointer.
Definition at line 329 of file kcombobox.cpp.
◆ setEditUrl()
void KComboBox::setEditUrl | ( | const QUrl & | url | ) |
Sets url
into the edit field of the combo box.
It uses QUrl::toDisplayString() so that the url is properly decoded for displaying.
Definition at line 167 of file kcombobox.cpp.
◆ setLineEdit()
|
virtual |
Reimplemented for internal reasons.
API remains unaffected. Note that QComboBox::setLineEdit is not virtual in Qt4, do not use a KComboBox in a QComboBox pointer.
NOTE: Only editable combo boxes can have a line editor. As such any attempt to assign a line edit to a non-editable combo box will simply be ignored.
Definition at line 237 of file kcombobox.cpp.
◆ setTrapReturnKey()
void KComboBox::setTrapReturnKey | ( | bool | trap | ) |
By default, KComboBox recognizes Key_Return and Key_Enter and emits the returnPressed(const QString &) signal, but it also lets the event pass, for example causing a dialog's default button to be called.
Call this method with trap
set to true to make KComboBox stop these events. The signals will still be emitted of course.
- Note
- This only affects editable combo boxes.
- See also
- setTrapReturnKey()
Definition at line 149 of file kcombobox.cpp.
◆ substringCompletion
|
signal |
Emitted when the shortcut for substring completion is pressed.
◆ textRotation
|
signal |
Emitted when the text rotation key bindings are pressed.
The argument indicates which key binding was pressed. In this case this can be either one of four values: PrevCompletionMatch
, NextCompletionMatch
, RotateUp
or RotateDown
.
Note that this signal is not emitted if the completion mode is set to CompletionNone.
