Q: The book shows without any problem using QTextWidget browser, but when I use KHTMLPart browser, I get the following error:
|
|
|
An error occurred while loading ms-its:/home/user/Symphony FrameWork.chm::/index.html
|
|
|
The file or folder ms-its:/home/user/Symphony FrameWork.chm::/index.html does not exist.
|
|
|
|
|
|
A: You have kio_chm installed, and because it installs itself as KIO slave for ms-its, sometime KDE uses it instead of kio_msits.
|
|
|
To disable it, find the file chm.protocol in your KDE directory, and remove it. Then run tdeinit to reread the configuration.
|
|
|
|
|
|
|
|
|
Q: When I open CHM document, there is no "Contents" or "Index" tab.
|
|
|
A: The files required for Content or Index tabs are not present in chm file. Therefore it is not possible to show those tabs.
|
|
|

|
Q: I use KDE. Which browser is better to use - KHTMLPart or QTextBrowser?
|
|
|
A: QTextBrowser was reported to be faster, except for multibyte languages (Japanese/Chinese/Korean).
|
|
|
However KHTMLPart is obviously more standard-compliant. I use KHTMLPart.

Q: Font size increasing button does not increase the font size, just changes the font to bold once.
|
|
|
A: Make sure you use resizeable (true type) fonts. The described behavior is expected when bitmap fonts are used, as their size
|
|
|
could not be changed. Check your system configuration.

Questions about search.
|
|
|
Before version 3.0 is out there was only one search engine, which is still available in Advanced settings as "search engine based on internal CHM index".
|
|
|
The following questions are only related to the old search engine, and are fixed in a new one.
|
|
|
|
|
|
Q: Why my search for "for this" found no documents even though I know there are documents containing this phrase?
|
|
|
Q: Why my search for "C++" or "argv[0]" found no documents even though I know there are documents containing this phrase?
|
|
|
Q: Why the search tab is not shown?
|
|
|
|
|
|
A: The search does not look through all the documents. Instead it uses the previously generated index stored in CHM file. If the index
|
|
|
is not present in the file, the search is not possible.
|
|
|
However the indexing procedure in Microsoft HTML Help Workshop does not index the symbols (except underscore), single letters
|
|
|
and common words like for, this, to, do, etc. Therefore those words and symbols are not in index file, so search for "C++"
|
|
|
will not be found.
|
|
|
Also the the indexing procedure in Microsoft HTML Help Workshop brokes the ASCII characters which are outside 7-bit ASCII table. Therefore
|
|
|
search using European/Russian letters often produces strange results, finding the pages with no search words present, and does not work
|
|
|
with Asian langiages.
|
|
|
|
|
|
The solution is new kchmviewer search engine. It is also index-based, but the index is generated by chmviewer. Every symbol is indexed,
|
|
|
so seach for "C++" or "argv[0]" will find the appropriate code. It uses Unicode inside, so it has no problem with any language, including
|
|
|
Japanese, Chinese and Korean.
