11.7

Added

• Delphi 10 Seattle Support
• Lazarus 1.6 Support
• Linux (GTK2) Support
• Raspbian (GTK2) Support
• Detect UTF16 w/o BOM. Helps reading UnicodeStrings written to Streams.
• Scrolling in unfocused HtmlViewer.
• TFloatingObj supports style Position:Absolute
• Position:fixed for Blocks and Images
• HtmlViewer supports !important now
• Working With Protocols
  • New unit UrlConn makes it easy for coders to add own protocol handlers for a TFrameBrowser
    • New base class ThtConnection offers to get a document.
    • New class ThtFileConnection gets a document from a file.
    • New class ThtResourceConnection gets a document from the application's resources.
    • New component base class ThtConnector offers to create a connection for a protocol. When dropped to a form with a ThtConnectionManager on it ThtConnectors register themselves at the ThtConnectionManager automatically.
    • New component ThtFileConnector creates a ThtFileConnection for protocol 'file://'.
    • New component ThtResourceConnector creates a ThtResourceConnection for protocol 'res://'.
    • New component ThtConnectionManager creates ThtConnections for the registered protocols.
  • TFrameBrowser Demos promoted from Other Demos to Main Demos
    • FrameBrowserDemoIndy10.dpr for Delphi and Lazarus (Win32/Win64/Linux)
    • FrameBrowserDemoIcs.dpr for Delphi only
    • Both demos are using the same code except their specific THttpConnector/THttpConnection in unit UrlConId10 resp. UrlConIcs.

Enhanced

• Working With Images
  • Global image loader in unit HtmlImages, which enables coders to detect and load additional image formats:
    • base class ThtImageLoader
    • global procedure SetImageLoader
    • global function GetImageLoader
    • global function LoadImageFromStream uses the new global image loader
    • ThtImageLoader.GetFilter() returns a filter for file open dialogs.
    • Removed global function LoadImageFromFile: now done by new local procedure GetTheFile in ThtDocument.GetTheImage.
  • Added: ThtGraphicImage: support for all TGraphics without own TBitmap, e.g. meta files
  • Changed: More general code due to enhanced ThtImage
  • Changed: ThtGpImage becomes a TGraphic
  • Changed: TGIFImage becomes a ThtBitmap
  • Removed: type TGpObject no longer needed
  • ThtBitmap extended and moved from unit HtmlGif2 to HtmlGlobals. ThtBitmap is needed to support TBitmap.Assign() in Lazarus 0.9.30, which is the current official version for Raspbian gtk2/ARM
