Struct qt_gui::QScreen

#[repr(C)]pub struct QScreen { /* fields omitted */ }

The QScreen class is used to query screen properties.

C++ class: QScreen.

C++ documentation:

The QScreen class is used to query screen properties.

A note on logical vs physical dots per inch: physical DPI is based on the actual physical pixel sizes when available, and is useful for print preview and other cases where it's desirable to know the exact physical dimensions of screen displayed contents.

Logical dots per inch are used to convert font and user interface elements from point sizes to pixel sizes, and might be different from the physical dots per inch. The logical dots per inch are sometimes user-settable in the desktop environment's settings panel, to let the user globally control UI and font sizes in different applications.

pub unsafe fn grab_window_5a(
    &self,
    window: c_ulonglong,
    x: c_int,
    y: c_int,
    w: c_int,
    h: c_int
) -> CppBox<QPixmap>

Creates and returns a pixmap constructed by grabbing the contents of the given window restricted by QRect(x, y, width, height).

Calls C++ function: QPixmap QScreen::grabWindow(unsigned long long window, int x = …, int y = …, int w = …, int h = …).

C++ documentation:

Creates and returns a pixmap constructed by grabbing the contents of the given window restricted by QRect(x, y, width, height).

The arguments (x, y) specify the offset in the window, whereas (width, height) specify the area to be copied. If width is negative, the function copies everything to the right border of the window. If height is negative, the function copies everything to the bottom of the window.

The window system identifier (WId) can be retrieved using the QWidget::winId() function. The rationale for using a window identifier and not a QWidget, is to enable grabbing of windows that are not part of the application, window system frames, and so on.

Warning: Grabbing windows that are not part of the application is not supported on systems such as iOS, where sandboxing/security prevents reading pixels of windows not owned by the application.

The grabWindow() function grabs pixels from the screen, not from the window, i.e. if there is another window partially or entirely over the one you grab, you get pixels from the overlying window, too. The mouse cursor is generally not grabbed.

Note on X11 that if the given window doesn't have the same depth as the root window, and another window partially or entirely obscures the one you grab, you will not get pixels from the overlying window. The contents of the obscured areas in the pixmap will be undefined and uninitialized.

On Windows Vista and above grabbing a layered window, which is created by setting the Qt::WA_TranslucentBackground attribute, will not work. Instead grabbing the desktop widget should work.

Warning: In general, grabbing an area outside the screen is not safe. This depends on the underlying window system.

pub unsafe fn virtual_siblings(&self) -> CppBox<QListOfQScreen>

Get the screen's virtual siblings.

Calls C++ function: QList<QScreen*> QScreen::virtualSiblings() const.

C++ documentation:

Get the screen's virtual siblings.

The virtual siblings are the screen instances sharing the same virtual desktop. They share a common coordinate system, and windows can freely be moved or positioned across them without having to be re-created.

pub unsafe fn virtual_size(&self) -> CppBox<QSize>

This property holds the pixel size of the virtual desktop to which this screen belongs

Calls C++ function: QSize QScreen::virtualSize() const.

C++ documentation:

This property holds the pixel size of the virtual desktop to which this screen belongs

Returns the pixel size of the virtual desktop corresponding to this screen.

This is the combined size of the virtual siblings' individual geometries.

Access functions:

QSize

virtualSize() const

Notifier signal:

void	virtualGeometryChanged(const QRect &rect)
