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 text
textRotation(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 text
returnKeyPressed(const QString &): this signal provides the current text in the widget as its argument whenever appropriate (this is in addition to the QLineEdit::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:

KLineEdit *edit = new KLineEdit(this);
KCompletion *comp = edit->completionObject();
// Connect to the Return pressed signal - optional
connect(edit, &KLineEdit::returnKeyPressed, comp, [this](const QString &text) { addItem(text); });

To use a customized completion object or your own completion object:

KLineEdit *edit = new KLineEdit(this);
KUrlCompletion *comp = new KUrlCompletion();
edit->setCompletionObject(comp);
// Connect to the return pressed signal - optional
connect(edit, &KLineEdit::returnKeyPressed, comp, [this](const QString &text) { addItem(text); });

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:

edit->setAutoDeleteCompletionObject(true);

KCompletionBase::setAutoDeleteCompletionObject

void setAutoDeleteCompletionObject(bool autoDelete)

Sets the completion object when this widget's destructor is called.

Definition kcompletionbase.cpp:143

Miscellaneous function calls :

// Tell the widget to not handle completion and iteration automatically
edit->setHandleSignals(false);
 
// Set your own key-bindings for a text completion mode
edit->setKeyBinding(KCompletionBase::TextCompletion, Qt::End);
 
// Hide the context (popup) menu
edit->setContextMenuPolicy(Qt::NoContextMenu);
 
// Default the key-bindings back to the default system settings
edit->useGlobalKeyBindings();

◆ 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.

See also: trapReturnKey()

Definition at line 1059 of file klineedit.cpp.

◆ setUrl()

void KLineEdit::setUrl ( const QUrl & url )

It uses QUrl::toDisplayString() so that the url is properly decoded for displaying.

Definition at line 1071 of file klineedit.cpp.

◆ setUrlDropsEnabled()

void KLineEdit::setUrlDropsEnabled ( bool enable )

Enables/Disables handling of URL drops.

If enabled and the user drops an URL, the decoded URL will be inserted. Otherwise the default behavior of QLineEdit is used, which inserts the encoded URL. Call setUrlDropsEnabled(false) if you need dropEvent to be called in a KLineEdit subclass.

Parameters

enable If true, insert decoded URLs

◆ setUserSelection()

void KLineEdit::setUserSelection ( bool userSelection )

protected

Sets the widget in userSelection mode or in automatic completion selection mode.

This changes the colors of selections.

signal

Emitted when the shortcut for substring completion is pressed.

◆ textRotation

void KLineEdit::textRotation ( KCompletionBase::KeyBindingType )

signal

Emitted when the text rotation key-bindings are pressed.

The argument indicates which key-binding was pressed. In KLineEdit's case this can be either one of two values: PrevCompletionMatch or NextCompletionMatch. See KCompletionBase::setKeyBinding for details.

Note that this signal is not emitted if the completion mode is set to CompletionNone or echoMode() is not normal.

◆ trapReturnKey()

bool KLineEdit::trapReturnKey ( ) const

Returns: true if keyevents of Key_Return or Key_Enter will be stopped or if they will be propagated.

See also: setTrapReturnKey ()

Definition at line 1065 of file klineedit.cpp.

bool KLineEdit::urlDropsEnabled ( ) const

Returns true when decoded URL drops are enabled.

Definition at line 1053 of file klineedit.cpp.

◆ userCancelled

void KLineEdit::userCancelled ( const QString & cancelText )

Definition at line 1111 of file klineedit.cpp.

◆ userText()

QString KLineEdit::userText ( ) const

Returns the text as given by the user (i.e.

not autocompleted) if the widget has autocompletion disabled, this function returns the same as QLineEdit::text().
