These options control the status bar, which appears at the bottom of the Lister or file display.
If you turn this option on, the icon changes to a icon. Clicking this icon lets you lock the folder format, to prevent it being changed automatically when you navigate to other folders. A brief animation is shown when the folder format is locked this way (just to let you know something has happened). In this mode, you need to right-click the icon to show the format menu.
You can tell Opus exactly what information to display on the status bar. By default a count of files, folders (and how many are selected) is shown, but you can configure the display to include much more information, including total playing time for music files and bar graphs to represent things like the proportion of space selected files would take up on a DVD. The text that tells Opus what to display on the status bar is known as its definition.
There are three different definition styles available. You can choose either:
The following options determinate which combination you want to use:
Depending on the state of the Separate definitions option there will either be one or two multi-line text fields on this page, for you to edit the definition text. Each line of the status bar definition corresponds to a "section" on the status bar. You can align or pad sections, and even have sections hidden based on simple conditions.
This image shows the default status bar definition. Not counting the comments that begin with //, there are ten lines in the text field, which means ten separate sections in the status bar. As you can probably tell, you tell Opus which information to display using a series of {..} codes, which are described in detail in the reference section. The Codes drop-down above the text field also provides a full list with descriptions of their meanings.
Below the text field is a small preview of the status bar - this updates in real time, so as you make changes to the status bar definition you can get an idea for how it will look in real life. A red highlight indicates the section you're currently editing.
The first line of text in the status bar definition shown above corresponds to the first section in the preview, and so on.
See the Status Bar Codes reference section for the full list of codes you can use.
