Member Function Documentation

[static] bool QWindowsWindowFunctions::isTabletMode()

This is a convenience function that can be used directly instead of resolving the function pointer. Returns true if Windows 10 operates in Tablet Mode. In this mode, Windows forces all application main windows to open in maximized state. Applications should then avoid resizing windows or restoring geometries to non-maximized states.

This function was introduced in Qt 5.9.

See also QWidget::showMaximized(), QWidget::saveGeometry(), and QWidget::restoreGeometry().

[static] const QByteArray QWindowsWindowFunctions::isTabletModeIdentifier()

Returns a bytearray that can be used to query QGuiApplication::platformFunction() to retrieve the IsTabletModeType function.

This function was introduced in Qt 5.9.

[static] void QWindowsWindowFunctions::setHasBorderInFullScreen(QWindow *window, bool border)

This is a convenience function that can be used directly instead of resolving the function pointer. window and border will be relayed to the function retrieved by QGuiApplication. When border is true then it will enable the WS_BORDER flag in full screen mode to enable other top level windows inside the application to appear on top when required.

Note: The setting must be applied before showing the window or switching it to full screen. For QML, setHasBorderInFullScreenDefault() can be used to set a default value.

This function was introduced in Qt 5.6.

[static] void QWindowsWindowFunctions::setHasBorderInFullScreenDefault(bool border)

This is a convenience function that can be used directly instead of resolving the function pointer. border will be relayed to the function retrieved by QGuiApplication. When border is true, the WS_BORDER flag will be set in full screen mode for all windows by default.

This function was introduced in Qt 5.13.

See also setHasBorderInFullScreen().

[static] const QByteArray QWindowsWindowFunctions::setHasBorderInFullScreenDefaultIdentifier()

This function returns the bytearray that can be used to query QGuiApplication::platformFunction to retrieve the SetHasBorderInFullScreen function.

This function was introduced in Qt 5.13.

[static] const QByteArray QWindowsWindowFunctions::setHasBorderInFullScreenIdentifier()

This function returns the bytearray that can be used to query QGuiApplication::platformFunction to retrieve the SetHasBorderInFullScreen function.

This function was introduced in Qt 5.6.

[static] void QWindowsWindowFunctions::setTouchWindowTouchType(QWindow *window, QWindowsWindowFunctions::TouchWindowTouchTypes type)

This is a convenience function that can be used directly instead of resolving the function pointer. window and type will be relayed to the function retrieved by QGuiApplication

[static] const QByteArray QWindowsWindowFunctions::setTouchWindowTouchTypeIdentifier()

This function returns the bytearray that can be used to query QGuiApplication::platformFunction to retrieve the SetTouchWindowTouchType function.

[static] void QWindowsWindowFunctions::setWindowActivationBehavior(QWindowsWindowFunctions::WindowActivationBehavior behavior)

This is a convenience function that can be used directly instead of resolving the function pointer. behavior will be relayed to the function retrieved by QGuiApplication.

This function was introduced in Qt 5.7.

See also QWidget::activateWindow() and QWindow::requestActivate().

[static] const QByteArray QWindowsWindowFunctions::setWindowActivationBehaviorIdentifier()

This function returns a bytearray that can be used to query QGuiApplication::platformFunction() to retrieve the SetWindowActivationBehaviorType function.

This function was introduced in Qt 5.7.
