void QScreen:: primaryOrientationChanged( Qt::ScreenOrientation orientation) Note: Notifier signal for property orientation. This signal is emitted when the primary orientation of the screen changes with orientation as an argument. Note: Notifier signal for property primaryOrientation. int QScreen:: angleBetween( Qt::ScreenOrientation a, Qt::ScreenOrientation b) constĬonvenience function to compute the angle of rotation to get from rotation a to rotation b. QPixmap QScreen:: grabWindow( WId window, int x = 0, int y = 0, int width = -1, int height = -1)Ĭreates 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 offset and size arguments are specified in device independent pixels.
The returned pixmap may be larger than the requested size when grabbing from a high-DPI screen. Call QPixmap::devicePixelRatio() to determine if this is the case. The window system identifier ( WId) can be retrieved using the QWidget::winId() function.
#Sdcafiine 5.5.2 loadiine windows
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: In general, grabbing an area outside the screen is not safe. QPlatformScreen *QScreen:: handle() const This depends on the underlying window system. QRect QScreen:: mapBetween( Qt::ScreenOrientation a, Qt::ScreenOrientation b, const QRect & rect) const bool QScreen:: isPortrait( Qt::ScreenOrientation o) constĬonvenience function that returns true if o is either portrait or inverted portrait otherwise returns false.īool QScreen:: isLandscape( Qt::ScreenOrientation o) constĬonvenience function that returns true if o is either landscape or inverted landscape otherwise returns false.
Maps the rect between two screen orientations. Qt::ScreenOrientations QScreen:: orientationUpdateMask() const This will flip the x and y dimensions of the rectangle rect if the orientation a is Qt::PortraitOrientation or Qt::InvertedPortraitOrientation and orientation b is Qt::LandscapeOrientation or Qt::InvertedLandscapeOrientation, or vice versa.
#Sdcafiine 5.5.2 loadiine update
Returns the currently set orientation update mask. void QScreen:: setOrientationUpdateMask( Qt::ScreenOrientations mask) Sdcafiine 5.5.2 black screen update# Sets the orientations that the application is interested in receiving updates for in conjunction with this screen.įor example, to receive orientation() updates and thus have orientationChanged() signals being emitted for LandscapeOrientation and InvertedLandscapeOrientation, call setOrientationUpdateMask() with mask set to Qt::LandscapeOrientation | Qt::InvertedLandscapeOrientation. The default, 0, means no orientationChanged() signals are fired. QTransform QScreen:: transformBetween( Qt::ScreenOrientation a, Qt::ScreenOrientation b, const QRect & target) constĬonvenience function to compute a transform that maps from the coordinate system defined by orientation a into the coordinate system defined by orientation b and target dimensions target.Įxample, a is Qt::Landscape, b is Qt::Portrait, and target is QRect(0, 0, w, h) the resulting transform will be such that the point QPoint(0, 0) is mapped to QPoint(0, w), and QPoint(h, w) is mapped to QPoint(0, h). Thus, the landscape coordinate system QRect(0, 0, h, w) is mapped (with a 90 degree rotation) into the portrait coordinate system QRect(0, 0, w, h). QScreen *QScreen:: virtualSiblingAt( QPoint point) Qt::PrimaryOrientation is interpreted as the screen's primaryOrientation().
