Detailed Description

Record a QKeySequence by listening to key events in a window.

After calling startRecording key events in the set window will be captured until a valid QKeySequence has been recorded and gotKeySequence is emitted. See multiKeyShortcutsAllowed and modifierlessAllowed for what constitutes a valid key sequence.

During recording any shortcuts are inhibited and cannot be triggered. Either by using the keyboard-shortcuts-inhibit protocol on Wayland or grabbing the keyboard.

For graphical elements that record key sequences and can optionally perform conflict checking against existing shortcuts see KKeySequenceWidget and KeySequenceItem.

Property Documentation

◆ currentKeySequence

QKeySequence KeySequenceRecorder::currentKeySequence
readwrite

The recorded key sequence.

After construction this is empty.

During recording it is continuously updated with the newest user input.

After recording it contains the last recorded QKeySequence

Definition at line 57 of file keysequencerecorder.h.

◆ isRecording

bool KeySequenceRecorder::isRecording
read

Whether key events are currently recorded.

Definition at line 48 of file keysequencerecorder.h.

◆ modifierlessAllowed

bool KeySequenceRecorder::modifierlessAllowed
readwrite

If key presses of "plain" keys without a modifier are considered to be a valid finished key combination.

Plain keys include letter and symbol keys and text editing keys (Return, Space, Tab, Backspace, Delete). Other keys like F1, Cursor keys, Insert, PageDown will always work.

By default this is false.

Definition at line 70 of file keysequencerecorder.h.

◆ modifierOnlyAllowed

bool KeySequenceRecorder::modifierOnlyAllowed
readwrite

It makes it acceptable for the key sequence to be just a modifier (e.g.

Shift or Control)

By default, if only a modifier is pressed and then released, the component will remain waiting for the sequence. When enabled, it will take the modifier key as the key sequence.

By default this is false.

Definition at line 91 of file keysequencerecorder.h.

◆ multiKeyShortcutsAllowed

bool KeySequenceRecorder::multiKeyShortcutsAllowed
readwrite

Controls the amount of key combinations that are captured until recording stops and gotKeySequence is emitted.

By default this is true and "Emacs-style" key sequences are recorded. Recording does not stop until four valid key combination have been recorded. Afterwards currentKeySequence().count() will be 4.

Otherwise only one key combination is recorded before gotKeySequence is emitted with a QKeySequence with a count() of 1.

Definition at line 81 of file keysequencerecorder.h.

◆ window

QWindow * KeySequenceRecorder::window
readwrite

The window in which the key events are happening that should be recorded.

Definition at line 61 of file keysequencerecorder.h.

Constructor & Destructor Documentation

◆ KeySequenceRecorder()

KeySequenceRecorder::KeySequenceRecorder ( QWindow window,
QObject parent = nullptr 
)
explicit

Constructor.

window The window whose key events will be recorded.

window

Member Function Documentation

◆ cancelRecording

void KeySequenceRecorder::cancelRecording ( )
slot

Stops the recording session.

Definition at line 490 of file keysequencerecorder.cpp.

◆ gotKeySequence

void KeySequenceRecorder::gotKeySequence ( const QKeySequence keySequence)
signal

This signal is emitted when a key sequence has been recorded.

Compared to currentKeySequenceChanged and currentKeySequence this is signal is not emitted continuously during recording but only after recording has finished.

◆ startRecording()

void KeySequenceRecorder::startRecording ( )

Start recording.

Calling startRecording when window() is nullptr has no effect.
