Info Tip

The Info Tip page in the file type editor lets you define what is shown on the info tip (the popup tooltip) that's displayed when the mouse hovers over files of this type.

When Opus looks for an info tip to display for a file, it checks file types in the following order:

1. The specific file type for that file (e.g. for a .jpg file this might be the JPEG Image file type)
2. The file type group that contains that file extension (e.g. Images)
3. The Recognized images file type if the file is a recognized image file
4. The All files file type (or for a folder, All folders)
5. The All files and folders file type.

The first, most specific, info tip found is the one used. So if you want to assign an info tip to all members of a group you can edit the file type group definition, and then override it on a per file-type basis if needed.

The info tip definition (the image above illustrates the default info tip for the Images group) uses various {..} codes to insert information about the file into the info tip. Each line in the edit field corresponds to a line in the info tip. If a line in the definition uses a code that isn't valid for the specified file (for example, a .bmp file doesn't support EXIF metadata in it, and so fields like {cameramake} would be empty), the whole line is omitted from the info tip. You can have multiple codes on the one line and in that case, the line is only omitted if all codes on the line are empty.

You can see that for the .jpg file in the above screenshot, all the EXIF information defined in the info tip is shown, but the info tip for the .bmp file simply displays the top line ({desc} produces the 800 x 599 x 24 Bitmap Image description and {thumbnail} displays the image's thumbnail).

The keywords used in info tips are the same as used by the Rename function when renaming files using metadata, and the Set command when adding and removing columns to the file display. See the Keywords for Columns page for a full list of supported keywords. There are several special keywords that are specific to the info tip definition:

• {foldersize}: This code applies to the info tips for folders, and its use will cause Opus to calculate the total size of the folder when its info tip is displayed. This lets you display the size of a folder by simply hovering over it.
• {foldercontent}: This code also applies to folders; it will result in Opus displaying the names of the first few files and sub-folders contained in the folder.
• {thumbnail}: This code displays the thumbnail for the file if Opus is able to generate one. You can configure how the thumbnail is displayed by appending a value to the code:
  • {thumbnail:0} displays the thumbnail with no border (frame)
  • {thumbnail:1} displays the thumbnail with a normal border (this is the default if no value is given)
  • {thumbnail:2} displays a border if the thumbnail does not have an alpha channel. For 32 bit images with an alpha channel (transparency) no border is shown.
  • {thumbnail:3} displays no border for folders, but normal borders for files
• {infotip}: This code causes Opus to display the standard, system info tip for the file (if there is one). This would be the text that is shown in the tooltip in Explorer when you hover over the file. The main use for this is to display information from third-party tooltip shell extensions that you may have installed.

Any text you enter into the info tip definition that isn't a {..} code is displayed as-is (unless it appears on a line that uses a non-applicable {..} code, in which case the whole line is omitted as described above). You can also use some simple HTML-style markup codes to control font styles in the info tip:

• <#RRGGBB>...</#>: This sets the text color for text between the tags. The color is given in hexadecimal, e.g. <#32CD32>Hello!</#> would display the text Hello! in lime green.
• <b>..</b>: This displays text between the tags in bold.
• <i>..</i>: This displays the text between the tags in italics.
• <u>..</u>: This underlines the text between the tags.

At the bottom of the info tip page are several buttons:

• Insert Field: This displays a drop-down list of all the information fields (arranged by category) that you can use in info tips. This list is also automatically displayed in a pop-up menu when you press the { key in the info tip definition field. So don't worry, you don't have to memorise all of the codes!
• Samples: This lets you access several sample info tip definitions for reference (the samples are the defaults for the various default file type groups plus generic info tips for other files and folders).
• Clear: Clears the info tip definition completely.
• Never show an InfoTip for this File Type: If this option is on, the info tip field will be disabled and Opus will be prevented from ever showing an info tip for this type of file (hovering over the file will do nothing).
