Path for gd.addHelp()

[John Dunsmuir]

I'm adding help resources to some macros and plugins.

In macros

dir = getDirectory("plugins");
dir = replace(dir,"\\","/");
myURL="file:///"+dir+"FloodFill/FloodFillHelp/FloodFill_Connectivity_Scan.htm";

works OK but I don't know how to fix the pesky backslashes in a plugin. Hard coding the path works but isn't an option for me.

Thanks,
John D.

It would be better to inline the HTML help, as in the example at

    http://imagej.nih.gov/ij/macros/examples/DialogWithHelp.txt

With plugins, the HTML file can be stored in a jar file along with the plugin. The example at

   http://imagej.nih.gov/ij/plugins/pcl-demo.html

demonstrates how resources needed by a plugin, such as text files, can be loaded from a jar file.

Thanks Wayne,  I'll have a look at the jar approach, it should help a lot to keep all of the resources together.  I did solve my original backslash question.

                dir = IJ.getDirectory("plugins");
                dir= dir.replace("\\","/");
                myURL = "file:///"+dir + "FloodFill/FloodFillHelp/myFloodFill_Help.htm";
