1 GNU LESSER GENERAL PUBLIC LICENSE 2 3 The Qt Toolkit is Copyright (C) 2016 The Qt Company Ltd. 4 Contact: http://www.qt.io/licensing/ 5 6 You may use, distribute and copy the Qt Toolkit under the terms of 7 GNU Lesser General Public License version 3, which is displayed below. 8 This license makes reference to the version 3 of the GNU General 9 Public License, which you can find in the LICENSE.GPL3 file. 10 11------------------------------------------------------------------------- 12 13 GNU LESSER GENERAL PUBLIC LICENSE 14 Version 3, 29 June 2007 15 16 Copyright © 2007 Free Software Foundation, Inc. <http://fsf.org/> 17Everyone is permitted to copy and distribute verbatim copies of this 18licensedocument, but changing it is not allowed. 19 20This version of the GNU Lesser General Public License incorporates 21the terms and conditions of version 3 of the GNU General Public 22License, supplemented by the additional permissions listed below. 23 240. Additional Definitions. 25 26 As used herein, “this License” refers to version 3 of the GNU Lesser 27General Public License, and the “GNU GPL” refers to version 3 of the 28GNU General Public License. 29 30 “The Library” refers to a covered work governed by this License, 31other than an Application or a Combined Work as defined below. 32 33 An “Application” is any work that makes use of an interface provided 34by the Library, but which is not otherwise based on the Library. 35Defining a subclass of a class defined by the Library is deemed a mode 36of using an interface provided by the Library. 37 38 A “Combined Work” is a work produced by combining or linking an 39Application with the Library. The particular version of the Library 40with which the Combined Work was made is also called the “Linked 41Version”. 42 43 The “Minimal Corresponding Source” for a Combined Work means the 44Corresponding Source for the Combined Work, excluding any source code 45for portions of the Combined Work that, considered in isolation, are 46based on the Application, and not on the Linked Version. 47 48 The “Corresponding Application Code” for a Combined Work means the 49object code and/or source code for the Application, including any data 50and utility programs needed for reproducing the Combined Work from the 51Application, but excluding the System Libraries of the Combined Work. 52 531. Exception to Section 3 of the GNU GPL. 54 55 You may convey a covered work under sections 3 and 4 of this License 56without being bound by section 3 of the GNU GPL. 57 582. Conveying Modified Versions. 59 60 If you modify a copy of the Library, and, in your modifications, a 61facility refers to a function or data to be supplied by an Application 62that uses the facility (other than as an argument passed when the 63facility is invoked), then you may convey a copy of the modified 64version: 65 66 a) under this License, provided that you make a good faith effort 67 to ensure that, in the event an Application does not supply the 68 function or data, the facility still operates, and performs 69 whatever part of its purpose remains meaningful, or 70 71 b) under the GNU GPL, with none of the additional permissions of 72 this License applicable to that copy. 73 743. Object Code Incorporating Material from Library Header Files. 75 76 The object code form of an Application may incorporate material from 77a header file that is part of the Library. You may convey such object 78code under terms of your choice, provided that, if the incorporated 79material is not limited to numerical parameters, data structure 80layouts and accessors, or small macros, inline functions and templates 81(ten or fewer lines in length), you do both of the following: 82 83 a) Give prominent notice with each copy of the object code that 84 the Library is used in it and that the Library and its use are 85 covered by this License. 86 87 b) Accompany the object code with a copy of the GNU GPL and this 88 license document. 89 904. Combined Works. 91 92 You may convey a Combined Work under terms of your choice that, taken 93together, effectively do not restrict modification of the portions of 94the Library contained in the Combined Work and reverse engineering for 95debugging such modifications, if you also do each of the following: 96 97 a) Give prominent notice with each copy of the Combined Work that 98 the Library is used in it and that the Library and its use are 99 covered by this License. 100 101 b) Accompany the Combined Work with a copy of the GNU GPL and this 102 license document. 103 104 c) For a Combined Work that displays copyright notices during 105 execution, include the copyright notice for the Library among 106 these notices, as well as a reference directing the user to the 107 copies of the GNU GPL and this license document. 108 109 d) Do one of the following: 110 111 0) Convey the Minimal Corresponding Source under the terms of 112 this License, and the Corresponding Application Code in a form 113 suitable for, and under terms that permit, the user to 114 recombine or relink the Application with a modified version of 115 the Linked Version to produce a modified Combined Work, in the 116 manner specified by section 6 of the GNU GPL for conveying 117 Corresponding Source. 118 119 1) Use a suitable shared library mechanism for linking with 120 the Library. A suitable mechanism is one that (a) uses at run 121 time a copy of the Library already present on the user's 122 computer system, and (b) will operate properly with a modified 123 version of the Library that is interface-compatible with the 124 Linked Version. 125 126 e) Provide Installation Information, but only if you would 127 otherwise be required to provide such information under section 6 128 of the GNU GPL, and only to the extent that such information is 129 necessary to install and execute a modified version of the 130 Combined Work produced by recombining or relinking the Application 131 with a modified version of the Linked Version. (If you use option 132 4d0, the Installation Information must accompany the Minimal 133 Corresponding Source and Corresponding Application Code. If you 134 use option 4d1, you must provide the Installation Information in 135 the manner specified by section 6 of the GNU GPL for conveying 136 Corresponding Source.) 137 1385. Combined Libraries. 139 140 You may place library facilities that are a work based on the Library 141side by side in a single library together with other library 142facilities that are not Applications and are not covered by this 143License, and convey such a combined library under terms of your 144choice, if you do both of the following: 145 146 a) Accompany the combined library with a copy of the same work 147 based on the Library, uncombined with any other library 148 facilities, conveyed under the terms of this License. 149 150 b) Give prominent notice with the combined library that part of 151 it is a work based on the Library, and explaining where to find 152 the accompanying uncombined form of the same work. 153 1546. Revised Versions of the GNU Lesser General Public License. 155 156 The Free Software Foundation may publish revised and/or new versions 157of the GNU Lesser General Public License from time to time. Such new 158versions will be similar in spirit to the present version, but may 159differ in detail to address new problems or concerns. 160 161Each version is given a distinguishing version number. If the Library 162as you received it specifies that a certain numbered version of the 163GNU Lesser General Public License “or any later version” applies to 164it, you have the option of following the terms and conditions either 165of that published version or of any later version published by the 166Free Software Foundation. If the Library as you received it does not 167specify a version number of the GNU Lesser General Public License, 168you may choose any version of the GNU Lesser General Public License 169ever published by the Free Software Foundation. 170 171If the Library as you received it specifies that a proxy can decide 172whether future versions of the GNU Lesser General Public License shall 173apply, that proxy's public statement of acceptance of any version is 174permanent authorization for you to choose that version for the Library. 175 176
