Understanding GRML MDI browsers

GRML browsers share many common features, such as the support windows, the support toolbars, Navigation Bar, and Address Bar. However, the difference between browsers is determined by the display of file and web page content. There are two parts to a browser window. It has a form and a view.

Form.

The form displays input controls. These include edit boxes, selection boxes, and buttons. The form is displayed the same in all GRML MDI browsers.

View.

The view displays content. Content is created from column and result items.

These items are identified in GRML using tags. In CSV, or character-delimited formats, the first row usually contains the column items. All subsequent rows contain the result items.

Column items describe the items in a result. For each item in a result, there is a corresponding column item. These, column and result, items create the view of a browser window.
Form vs. view.

While the form displays the same, each browser uses a different view.

Examples.

Pioneer Report MDI.

Pioneer Report MDI reads a file or web page and displays content using a list control. List controls display columns (using a header control), rows, and thumbnails (if necessary).

Tree MDI.

Tree MDI uses a tree control. Tree controls display content using a hierarchy. Columns are NOT displayed. Rows ARE NOT displayed. Thumbnails are NOT displayed.

Content displays using a parent-child relationship. The parent item, of a result, shows the value of the first result item. The child items show the value of each result item (including the first).
