122 | \brief The QPlatformIntegration class is the entry for WindowSystem specific functionality. | - |
123 | | - |
124 | QPlatformIntegration is the single entry point for windowsystem specific functionality when | - |
125 | using the QPA platform. It has factory functions for creating platform specific pixmaps and | - |
126 | windows. The class also controls the font subsystem. | - |
127 | | - |
128 | QPlatformIntegration is a singleton class which gets instantiated in the QGuiApplication | - |
129 | constructor. The QPlatformIntegration instance do not have ownership of objects it creates in | - |
130 | functions where the name starts with create. However, functions which don't have a name | - |
131 | starting with create acts as accessors to member variables. | - |
132 | | - |
133 | It is not trivial to create or build a platform plugin outside of the Qt source tree. Therefore | - |
134 | the recommended approach for making new platform plugin is to copy an existing plugin inside | - |
135 | the QTSRCTREE/src/plugins/platform and develop the plugin inside the source tree. | - |
136 | | - |
137 | The minimal platform integration is the smallest platform integration it is possible to make, | - |
138 | which makes it an ideal starting point for new plugins. For a slightly more advanced plugin, | - |
139 | consider reviewing the directfb plugin, or the testlite plugin. | - |

150 | \fn QPlatformWindow *QPlatformIntegration::createPlatformWindow(QWindow *window) const | - |

153 | window which the QPlatformWindow is supposed to be created for. | - |
154 | | - |
155 | All top level windows have to have a QPlatformWindow, and it will be created when the | - |

161 | of the \a window should be applied to the underlying window. If the resulting flags or state | - |

195 | \value BufferQueueingOpenGL The OpenGL implementation on the platform will queue | - |
196 | up buffers when swapBuffers() is called and block only when its buffer pipeline | - |
197 | is full, rather than block immediately. | - |
198 | | - |
199 | \value MultipleWindows The platform supports multiple QWindows, i.e. does some kind | - |
