      • loadLibrary

        public static void loadLibrary​(java.lang.String name)
        Loads the shared library that matches the version of the Java code which is currently running. SWT shared libraries follow an encoding scheme where the major, minor and revision numbers are embedded in the library name and this along with name is used to load the library. If this fails, name is used in another attempt to load the library, this time ignoring the SWT version encoding scheme.
        Parameters:
        name - the name of the library to load

      • loadLibrary

        public static void loadLibrary​(java.lang.String name,
                               boolean mapName)
        Loads the shared library that matches the version of the Java code which is currently running. SWT shared libraries follow an encoding scheme where the major, minor and revision numbers are embedded in the library name and this along with name is used to load the library. If this fails, name is used in another attempt to load the library, this time ignoring the SWT version encoding scheme.
        Parameters:
        name - the name of the library to load
        mapName - true if the name should be mapped, false otherwise

      • getVersionString

        public static java.lang.String getVersionString()
        Returns:
        String Combined SWT version like 4826

      • findResource

        public static java.io.File findResource​(java.lang.String subDir,
                                        java.lang.String resourceName,
                                        boolean mapResourceName)

      • findResource

        public static java.io.File findResource​(java.lang.String subDir,
                                        java.lang.String resourceName,
                                        boolean mapResourceName,
                                        boolean replaceDylib,
                                        boolean searchInOsgi)
        Locates a resource located either in java library path, swt library path, or attempts to extract it from inside swt.jar file. This function supports a single level subfolder, e.g SubFolder/resource. Dev note: (17/12/07) This has been developed and throughly tested on GTK. Designed to work on Cocoa/Win as well, but not tested.
        Parameters:
        subDir - 'null' or a folder name without slashes. E.g Correct: 'mysubdir', incorrect: '/subdir/'. Platform specific Slashes will be added automatically.
        resourceName - e.g swt-webkitgtk
        mapResourceName - true if you like platform specific mapping applied to resource name. e.g MyLib -> libMyLib-gtk-4826.so
