Resource and Environment Variables

Views Studio sets up its own resources and environment variables in addition to those used by Views.

Resources

Views Studio uses the following resources:

  • menuBackground specifies the background color of Views Studio menus.

  • menuForeground specifies the foreground color of Views Studio menus.

  • menuFont specifies the font of Views Studio menus.

  • panelBackground specifies the background color of Views Studio panels.

  • toolBarBackground specifies the background color of Views Studio tool bars.

  • focusPathColor specifies the color of the lines drawing the focus path when using the Focus editing mode.

  • attachmentColor specifies the color of the lines delimiting the attachment guide when using the Attachments mode.

  • attachmentHighlightColor specifies the color of the selected item when using the Attachments mode.

  • legacyProtoInspector restores the deprecated IlvProtoGraphic window while inspecting a prototype gadget in Views Studio.

Environment Variables

Views Studio uses the following environment variables:

  • ILVSTOPTIONFILE specifies the user-defined option file to be loaded. The editor uses the ILVPATH environment variable to locate this file.

  • ILVSTIGNORINGBACKGROUND=true specifies whether the Gadget buffers should be saved without saving the background color. If this variable is set to true, the panels in your application will use the default background color.

  • ILVSTIGNORINGSIZE=true indicates whether the Gadget buffers should be saved without saving their dimensions.

  • ILVPRINTERCOMMANDLINE is used on UNIX® platforms only to specify the command line to be executed when the editor prints the buffer. The default value is "lpr -v %s". The specified string must be a valid C printf format, where %s is the name of the file to be printed.

  • ILVSTPLUGINS indicates a list of plug-ins you want to load. You can specify the full paths or the paths relative to the working directory, separated by a semicolon (;) character.

  • ILV_LEGACY_PROTO_INSPECTOR=true is used to for backward compatibility. Setting this environment variable restores the deprecated IlvProtoGraphic window while inspecting a prototype gadget in Views Studio.
