## Member Function Documentation

### QCapturableWindow::QCapturableWindow()

Constructs a null capturable window information that doesn't refer to any window.

### QCapturableWindow::QCapturableWindow(const QCapturableWindow &other)

Construct a new window information using other QCapturableWindow.

### `[noexcept]` QCapturableWindow::QCapturableWindow(QCapturableWindow &&other)

Constructs a QCapturableWindow by moving from other.

### `[noexcept]` QCapturableWindow::~QCapturableWindow()

Destroys the window information.

### QString QCapturableWindow::description() const

Returns a description of the window. In most cases it represents the window title.

Note: Getter function for property description.

### bool QCapturableWindow::isValid() const

Identifies whether a window information is valid.

An invalid window information refers to non-existing window or doesn't refer to any one.

Returns true if the window is valid, and false if it is not.

Note: Getter function for property isValid.

### `[noexcept]` void QCapturableWindow::swap(QCapturableWindow &other)

Swaps the current window information with other.

### `[noexcept]` QCapturableWindow &QCapturableWindow::operator=(QCapturableWindow &&other)

Moves other into this QCapturableWindow.

### QCapturableWindow &QCapturableWindow::operator=(const QCapturableWindow &other)

Assigns the other window information to this QCapturableWindow.

## Related Non-Members

### `[noexcept]` bool operator!=(const QCapturableWindow &lhs, const QCapturableWindow &rhs)

Returns `true` if window information lhs and rhs refer to different windows, otherwise returns `false`.

### `[noexcept]` bool operator==(const QCapturableWindow &lhs, const QCapturableWindow &rhs)

Returns `true` if window information lhs and rhs refer to the same window, otherwise returns `false`.
