This keyword is not expanded by Git which means it's not replaced with the correct revision value in the releases made using git-based scripts and it's confusing to have lines with unexpanded "$Id$" in the released files. As expanding them with Git is not that simple (it could be done with git archive and export-subst attribute) and there are not many benefits in having them in the first place, just remove all these lines. If nothing else, this will make an eventual transition to Git simpler. Closes #14487. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@74602 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775

/**

@class wxHtmlHelpController
|
|
|
|
This help controller provides an easy way of displaying HTML help in your
|
|
application (see @sample{html}, test example).
|
|
|
|
The help system is based on @b books (see wxHtmlHelpController::AddBook).
|
|
A book is a logical section of documentation (for example "User's Guide" or
|
|
"Programmer's Guide" or "C++ Reference" or "wxWidgets Reference").
|
|
The help controller can handle as many books as you want.
|
|
|
|
Although this class has an API compatible with other wxWidgets help controllers
|
|
as documented by wxHelpController, it is recommended that you use the enhanced
|
|
capabilities of wxHtmlHelpController's API.
|
|
|
|
wxHTML uses Microsoft's HTML Help Workshop project files (.hhp, .hhk, .hhc) as
|
|
its native format. The file format is described in @ref overview_html_helpformats.
|
|
The directory @c helpfiles in the @sample{html} contains sample project files.
|
|
|
|
Note that the Microsoft's HTML Help Workshop
|
|
(http://www.microsoft.com/downloads/details.aspx?FamilyID=00535334-c8a6-452f-9aa0-d597d16580cc)
|
|
also runs on other platforms using WINE (http://www.winehq.org/) and it can
|
|
be used to create the .hpp, .hhk and .hhc files through a friendly GUI.
|
|
The commercial tool HelpBlocks (http://www.helpblocks.com) can also create these files.

This is a combination of these flags:
|
|
- wxHF_TOOLBAR: The help window has a toolbar.
|
|
- wxHF_FLAT_TOOLBAR: The help window has a toolbar with flat buttons (aka coolbar).
|
|
- wxHF_CONTENTS: The help window has a contents panel.
|
|
- wxHF_INDEX: The help window has an index panel.
|
|
- wxHF_SEARCH: The help window has a search panel.
|
|
- wxHF_BOOKMARKS: The help window has bookmarks controls.
|
|
- wxHF_OPEN_FILES: Allows user to open arbitrary HTML document.
|
|
- wxHF_PRINT: The toolbar contains "print" button.
|
|
- wxHF_MERGE_BOOKS: The contents pane does not show book nodes.
|
|
All books are merged together and appear as single book to the user.
|
|
- wxHF_ICONS_BOOK: All nodes in contents pane have a book icon.
|
|
This is how Microsoft's HTML help viewer behaves.
|
|
- wxHF_ICONS_FOLDER: Book nodes in contents pane have a book icon, book's
|
|
sections have a folder icon. This is the default.
|
|
- wxHF_ICONS_BOOK_CHAPTER: Both book nodes and nodes of top-level
|
|
sections of a book (i.e. chapters) have a book icon, all other sections
|
|
(sections, subsections, ...) have a folder icon.
|
|
- wxHF_EMBEDDED: Specifies that the help controller controls an embedded
|
|
window of class wxHtmlHelpWindow that should not be destroyed when
|
|
the controller is destroyed.
|
|
- wxHF_DIALOG: Specifies that the help controller should create a
|
|
dialog containing the help window.
|
|
- wxHF_FRAME: Specifies that the help controller should create a frame
|
|
containing the help window.
|
|
This is the default if neither wxHF_DIALOG nor wxHF_EMBEDDED is specified.
|
|
- wxHF_MODAL: Specifies that the help controller should create a modal
|
|
dialog containing the help window (used with the wxHF_DIALOG style).
|
|
- wxHF_DEFAULT_STYLE: wxHF_TOOLBAR | wxHF_CONTENTS | wxHF_INDEX |
|

wxHF_SEARCH | wxHF_BOOKMARKS | wxHF_PRINT
