69 \class QWindow -

70 \inmodule QtGui -

71 \since 5.0 -

72 \brief The QWindow class represents a window in the underlying windowing system. -

73 -

74 A window that is supplied a parent becomes a native child window of -

75 their parent window. -

76 -

77 An application will typically use QWidget or QQuickView for its UI, and not -

78 QWindow directly. Still, it is possible to render directly to a QWindow -

79 with QBackingStore or QOpenGLContext, when wanting to keep dependencies to -

80 a minimum or when wanting to use OpenGL directly. The -

81 \l{Raster Window Example} and \l{OpenGL Window Example} -

82 are useful reference examples for how to render to a QWindow using -

83 either approach. -

84 -

85 \section1 Resource Management -

86 -

87 Windows can potentially use a lot of memory. A usual measurement is -

88 width times height times color depth. A window might also include multiple -

89 buffers to support double and triple buffering, as well as depth and stencil -

90 buffers. To release a window's memory resources, call the destroy() function. -

91 -

92 \section1 Content Orientation -

93 -

94 QWindow has reportContentOrientationChange() that can be used to specify -

95 the layout of the window contents in relation to the screen. The content -

96 orientation is simply a hint to the windowing system about which -

97 orientation the window contents are in. It's useful when you wish to keep -

98 the same window size, but rotate the contents instead, especially when -

99 doing rotation animations between different orientations. The windowing -

100 system might use this value to determine the layout of system popups or -

101 dialogs. -

102 -

103 \section1 Visibility and Windowing System Exposure -

104 -

105 By default, the window is not visible, and you must call setVisible(true), -

106 or show() or similar to make it visible. To make a window hidden again, -

107 call setVisible(false) or hide(). The visible property describes the state -

108 the application wants the window to be in. Depending on the underlying -

109 system, a visible window might still not be shown on the screen. It could, -

110 for instance, be covered by other opaque windows or moved outside the -

111 physical area of the screen. On windowing systems that have exposure -

112 notifications, the isExposed() accessor describes whether the window should -

113 be treated as directly visible on screen. The exposeEvent() function is -

114 called whenever the windows exposure in the windowing system changes. On -

115 windowing systems that do not make this information visible to the -

116 application, isExposed() will simply return the same value as isVisible(). -

117 -

118 QWindow::Visibility queried through visibility() is a convenience API -

119 combining the functions of visible() and windowState(). -

120 -

121 \section1 Rendering -

122 -

123 There are two Qt APIs that can be used to render content into a window, -

124 QBackingStore for rendering with a QPainter and flushing the contents -

125 to a window with type QSurface::RasterSurface, and QOpenGLContext for -

126 rendering with OpenGL to a window with type QSurface::OpenGLSurface. -

127 -

128 The application can start rendering as soon as isExposed() returns \c true, -

129 and can keep rendering until it isExposed() returns \c false. To find out when -

130 isExposed() changes, reimplement exposeEvent(). The window will always get -

131 a resize event before the first expose event. -

132 -

133 \section1 Initial Geometry -

134 -

135 If the window's width and height are left uninitialized, the window will -

136 get a reasonable default geometry from the platform window. If the position -

137 is left uninitialized, then the platform window will allow the windowing -

138 system to position the window. For example on X11, the window manager -

139 usually does some kind of smart positioning to try to avoid having new -

140 windows completely obscure existing windows. However setGeometry() -

141 initializes both the position and the size, so if you want a fixed size but -

142 an automatic position, you should call resize() or setWidth() and -

143 setHeight() instead. -

238 -

239 \value Windowed The window occupies part of the screen, but not necessarily -

240 the entire screen. This state will occur only on windowing systems which -

241 support showing multiple windows simultaneously. In this state it is -

242 possible for the user to move and resize the window manually, if -

243 WindowFlags permit it and if it is supported by the windowing system. -

244 -

245 \value Minimized The window is reduced to an entry or icon on the task bar, -

246 dock, task list or desktop, depending on how the windowing system handles -

247 minimized windows. -

248 -

249 \value Maximized The window occupies one entire screen, and the titlebar is -

250 still visible. On most windowing systems this is the state achieved by -

251 clicking the maximize button on the toolbar. -

252 -

253 \value FullScreen The window occupies one entire screen, is not resizable, -

254 and there is no titlebar. On some platforms which do not support showing -

255 multiple simultaneous windows, this can be the usual visibility when the -

256 window is not hidden. -

257 -

258 \value AutomaticVisibility This means to give the window a default visible -

259 state, which might be fullscreen or windowed depending on the platform. -

260 It can be given as a parameter to setVisibility but will never be -

261 read back from the visibility accessor. -

262 -

263 \value Hidden The window is not visible in any way, however it may remember -

264 a latent visibility which can be restored by setting AutomaticVisibility. -
