tk-components / Discussion / Help: practical knowledge, questions and wishes

Thanks for your work.

I tested my own HTML-helpfiles with your tkhelpbrowser-Tool Version 1.2 but I detected some problems:

My Original-SourceCode:

tkhelpbrowser_setHome [file join I:/speci htmlhelp 01-index.html]
tkhelpbrowser_showDoc $Home

gives me errormessages from the ASED-IDE:

SyntaxCheck Results for I:/speci/htmlhelp/tkhelpbrowser/tkshowhelp.tk:
Used Syntax-Checker: Frink 2.2.2 patch level 4
*** I:/speci/htmlhelp/tkhelpbrowser/tkshowhelp.tk Warning : variable "Home" might be used before being set (line 47)

To prevent this message I changed the SourceCode:

global Home
set Home [file join I:/speci htmlhelp 01-index.html]
#tkhelpbrowser_setHome [file join I:/speci htmlhelp 01-index.html]
tkhelpbrowser_showDoc $Home

Furthermore I detected problems, probably because of my Windows-Volume-Components starting with "I:/". I did the following workaround, but its not universally valid!:

In I:/speci/htmlhelp/tkhelpbrowser/htmlbrowser.tcl:
proc setupBrowser
set titlename [lindex [split $titlesearch :] 3]
(instead of: set titlename [lindex [split $titlesearch :] 2])

the same problem in:

             proc runHelpSearch
             set filebase [lindex [split $item :] 1]
(instead of: set filebase [lindex [split $item :] 0]
             set filetext [lindex [split $item :] 3]
(instead of: set filetext [lindex [split $item :] 2]

I would appreciate a general and portable solution.

I found difficulties with displaying some characters e.g. the TM-sign: ™(Trademark) in my helptext.

My special german characters "Umlaute:" äöüÄÖÜ and ß are o.k. but if I find those characters in the listed search-text, the displaying is wrong.

My additional wishes are the following ones:
- I would like to have all Buttons (Back-Button, Home-Button etc.) on the top of the window, not the bottom.
- The background-Color of the "Configure Text"-Button is similar to the foreground-color, so its bad to detect, that it is a Button-Function (on my Windows-XP-OS).
- The Indent-Level of the text-paragraphs: is it possible to set it to Zero?
- The Content- and Search-Frames appears generally. I wish to get it only, if I press a special button to display these frames. Thus there is direct enough place for my underlying help-function.
- I want to place the geometry-entries for my own help-window at the beginning of my script.
- I wish to control the background-color of my own help-window.

And still one question: what is about the "Hippo" HTML display library. I dont know it.

I plan to realize the complete help-function in my spec-i-project (http://spec-i.de/) with this tkhelpbrowser-Tool. Its a USB-spectrometer with a complete integration of the free math-tool scilab and taking full control to Tcl/Tk.

What do you think, when will the next version of your tkhelpbrowser appear?

Thanks for your work again.
