Detailed Description
An enhanced QLineEdit widget for inputting text.
Detail
This widget inherits from QLineEdit and implements the following additional functionalities:
- a completion object that provides both automatic and manual text completion as well as multiple match iteration features
- configurable key-bindings to activate these features
- a popup-menu item that can be used to allow the user to set text completion modes on the fly based on their preference
To support these features KLineEdit also emits a few more additional signals:
completion(const QString &)
: this signal can be connected to a slot that will assist the user in filling out the remaining texttextRotation(KeyBindingType)
: this signal is intended to be used to iterate through the list of all possible matches whenever there is more than one match for the entered textreturnKeyPressed(const QString &)
: this signal provides the current text in the widget as its argument whenever appropriate (this is in addition to theQLineEdit::returnPressed()
signal which KLineEdit inherits from QLineEdit).
This widget by default creates a completion object when you invoke the completionObject(bool)
member function for the first time or use setCompletionObject(KCompletion *, bool)
to assign your own completion object. Additionally, to make this widget more functional, KLineEdit will by default handle the text rotation and completion events internally when 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 set the boolean parameter in the above functions to false.
The default key-bindings for completion and rotation is 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 setting, by simply calling useGlobalSettings()
. An alternate method would be to default individual key-bindings by using setKeyBinding() with the default second argument.
If EchoMode
for this widget is set to something other than QLineEdit::Normal
, the completion mode will always be defaulted to CompletionNone. This is done purposefully to guard against protected entries, such as passwords, being cached in KCompletion's list. Hence, if the EchoMode
is not QLineEdit::Normal
, the completion mode is automatically disabled.
A read-only KLineEdit will have the same background color as a disabled KLineEdit, but its foreground color will be the one used for the read-write mode. This differs from QLineEdit's implementation and is done to give visual distinction between the three different modes: disabled, read-only, and read-write.
Usage
To enable the basic completion feature:
To use a customized completion object or your own completion object:
Note if you specify your own completion object you have to either delete it when you don't need it anymore, or you can tell KLineEdit to delete it for you:

◆ setTrapReturnKey()
void KLineEdit::setTrapReturnKey | ( | bool | trap | ) |
By default, KLineEdit recognizes Key_Return
and Key_Enter
and emits the returnPressed() signals, but it also lets the event pass, for example causing a dialog's default-button to be called.
Call this method with trap
= true
to make KLineEdit
stop these events. The signals will still be emitted of course.

or echoMode()
is not normal.
