68 \brief The QStyleHints class contains platform specific hints and settings. -

69 \inmodule QtGui -

70 -

71 An object of this class, obtained from QGuiApplication, provides access to certain global -

72 user interface parameters of the current platform. -

73 -

74 Access is read only; typically the platform itself provides the user a way to tune these -

75 parameters. -

76 -

77 Access to these parameters are useful when implementing custom user interface components, in that -

78 they allow the components to exhibit the same behaviour and feel as other components. -

100 If you support drag and drop in your application, and want to start a drag -

101 and drop operation after the user has moved the cursor a certain distance -

102 with a button held down, you should use this property's value as the -

103 minimum distance required. -

104 -

105 For example, if the mouse position of the click is stored in \c startPos -

106 and the current position (e.g. in the mouse move event) is \c currentPos, -

107 you can find out if a drag should be started with code like this: -
