Properties, General

Mode Current view mode.
Possible values:
  • vmodeText: Text mode
  • vmodeBinary: Binary mode (with fixed line length)
  • vmodeHex: Hex mode
  • vmodeUnicode: Unicode and Unicode/Hex modes
  • vmodeRTF: RTF/UTF-8 mode
  • vmodeMedia: Image/Multimedia mode
  • vmodeWeb: Internet mode
  • vmodeWLX: Plugins mode
Notes:
  • To activate the combined Unicode/Hex mode, user should call the Unicode mode twice.
  • Plugins mode is available only when "WLX" define is uncommented in ATViewerOptions.inc file.
  • UTF-8 encoded texts can be shown only under Windows 2000/XP+. This is due to a limitation of MS RichEdit control.
ModeDetect Enables mode auto-detection on file opening.
File type may be determined by extension or sometimes by contents (extension has higher priority than contents). The global variable ATViewerOptions contains extensions lists for different modes, it's declared as record: 
  type
    TATViewerGlobalOptions = record
      ExtText: string; //Text files
      ExtRTF: string; //RTF files
      ExtImages: string; //Image files
      ExtMedia: string; //Video and audio clips
      ExtWeb: string; //Internet documents
    end;
Note:
  • For Plugins mode the different plugin detection scheme is used: matched plugin is determined first by plugin detect-string, or, if plugin detect-string is empty, the first plugin that can load given file is shown. Plugins mode can have higher or lower priority than internal viewers: see PluginsHighPriority property.
ModesDisabledForDetect

  • To convert FileTime value to a readable string, you may use, for example, the FormatFileTime function from "Universal Viewer" demo.
IsFocused Enables control focusing on file opening.
Note:
  • Set to True if you use component as main form control (e.g. you have something like Universal Viewer demo). Set to False if you use component as additional optional control (e.g. you have something like Browser demo).
