There is a global structure declared in the module, so it's available to the main program. It's pretty simple:
gHelpX\ | ||
Split_BarPos.i | position of the vertical splitter bar | |
WinW.i | help window width | |
WinH.i | help window height | |
WinX.i | help window X position | |
WinY.i | help window Y position | |
HelpPath.s | currently used help directory path | |
TopicFile.s | currently used topic file name |
Mostly useful to remember the help window metrics between sessions.
