54 \inqmlmodule QtQuick.Window -

55 \ingroup qtquick-visual-utility -

56 \brief The Screen attached object provides information about the Screen an Item or Window is displayed on. -

57 -

58 The Screen attached object is valid inside Item or Item derived types, -

59 after component completion. Inside these items it refers to the screen that -

60 the item is currently being displayed on. -

61 -

62 The attached object is also valid inside Window or Window derived types, -

63 after component completion. In that case it refers to the screen where the -

64 Window was created. It is generally better to access the Screen from the -

65 relevant Item instead, because on a multi-screen desktop computer, the user -

66 can drag a Window into a position where it spans across multiple screens. -

67 In that case some Items will be on one screen, and others on a different -

68 screen. -

69 -

70 To use this type, you will need to import the module with the following line: -

71 \code -

72 import QtQuick.Window 2.2 -

73 \endcode -

74 It is a separate import in order to allow you to have a QML environment -

75 without access to window system features. -

76 -

77 Note that the Screen type is not valid at Component.onCompleted, because -

78 the Item or Window has not been displayed on a screen by this time. -

167 \deprecated -

168 -

169 The number of logical pixels per millimeter. This is the effective pixel -

170 density provided by the platform to use in image scaling calculations. -

171 -

172 Due to inconsistencies in how logical pixel density is handled across -

173 the various platforms Qt supports, it is recommended to -

174 use physical pixels instead (via the \c pixelDensity property) for -

175 portability. -

187 \qmlattachedproperty real Screen::devicePixelRatio -

190 -

191 The ratio between physical pixels and device-independent pixels for the screen. -

192 -

193 Common values are 1.0 on normal displays and 2.0 on Apple "retina" displays. -

195 /*! -

196 \qmlattachedproperty Qt::ScreenOrientation Screen::primaryOrientation -

197 \readonly -

198 -

199 This contains the primary orientation of the screen. If the -

200 screen's height is greater than its width, then the orientation is -

201 Qt.PortraitOrientation; otherwise it is Qt.LandscapeOrientation. -

202 -

203 If you are designing an application which changes its layout depending on -

204 device orientation, you probably want to use primaryOrientation to -

205 determine the layout. That is because on a desktop computer, you can expect -

206 primaryOrientation to change when the user rotates the screen via the -

207 operating system's control panel, even if the computer does not contain an -

208 accelerometer. Likewise on most handheld computers which do have -

209 accelerometers, the operating system will rotate the whole screen -

210 automatically, so again you will see the primaryOrientation change. -

211 */ -

212 /*! -

213 \qmlattachedproperty Qt::ScreenOrientation Screen::orientation -

214 \readonly -

215 -

216 This contains the current orientation of the screen, from the accelerometer -

217 (if any). On a desktop computer, this value typically does not change. -

218 -

219 If primaryOrientation == orientation, it means that the screen -

220 automatically rotates all content which is displayed, depending on how you -

221 hold it. But if orientation changes while primaryOrientation does NOT -

222 change, then probably you are using a device which does not rotate its own -

223 display. In that case you may need to use \l {Item::rotation}{Item.rotation} or -

224 \l {Item::transform}{Item.transform} to rotate your content. -

225 -

226 \note This property does not update unless a Screen::orientationUpdateMask -

227 is set to a value other than \c 0. -

228 */ -

229 /*! -

230 \qmlattachedmethod int Screen::angleBetween(Qt::ScreenOrientation a, Qt::ScreenOrientation b) -

231 -

232 Returns the rotation angle, in degrees, between the two specified angles. -

234 -

235 /*! -

236 \qmlattachedproperty Qt::ScreenOrientations Screen::orientationUpdateMask -

237 \since 5.4 -

238 -

239 This contains the update mask for the orientation. Screen::orientation -

240 only emits changes for the screen orientations matching this mask. -

241 -

242 By default it is set to the value of the QScreen that the window uses. -
