Abstract:
|
|
This example demonstrates the html help components.
|
|
|
|
THTMLHelpDatabase is a database - it contains the mapping from Keyword to
|
|
page.
|
|
|
|
THTMLBrowserHelpViewer is a viewer for HTML pages. It simply starts a
|
|
browser.
|
|
|
|
How was the example created:
|
|
Put a THTMLHelpDatabase on a form.
|
|
Set AutoRegister to true.
|
|
Set KeywordPrefix to 'HTML/'
|
|
Set BaseURL to 'file://html/'
|
|
|
|
Put a THTMLBrowserHelpViewer on the form.
|
|
Set AutoRegister to true.
|
|
|
|
Put a TEdit on a form.
|
|
Set HelpType to htKeyword
|
|
Set HelpKeyword to 'HTML/edit1.html'
|
|
|
|
Run the program.
|
|
Focus the edit field and press F1. A browser will be started to show
|
|
the page 'html/edit1.html'.
