# The main GGv window

Every document has a main window. The main window consists of a menu bar, a scrolling pane, buttons for zooming and navigating between pages, a list of pages and finally the main view of the PostScript document.

- Main View. The main view displays the document page. If the monitor is large enough or if the page is small enough, the view will display the entire page, otherwise you will only section of it. In the sake of simplicity, we will refer to the main view as the view.

- Scrolling pane. The scrolling pane is the rectangular area at the top left corner of GGv. The scrolling pane is a visual representation of the complete page currently displayed in the view. The scrolling pane has an engraved rectangle inside. This rectangle is a representation of the current view (as displayed by the view) with regard to the complete current page. An example might be the easiest way to understand this: load a document, resize GGv to the point that you can only see part of the document; look now at the scrolling pane. The smaller the window, the smaller the engraved rectangle. We will refer to the engraved rectangle as the slider. The slider, as it name implies, can be moved around. Drag it around, and you will see what I mean. In other words, the size of the slider with respect to the scrolling pane represents how large is the view with respect to the document, and the location of the slider represents the location of the view. If the complete page is being displayed in the view, then the size of the slider is the same as the scrolling pane.

- List of Pages. The list of numbers at the bottom left is the list of pages available in the PostScript document.

There are several different ways to move: the cursor keys can be used to move in the desired direction, the spacebar moves in the direction of reading (assuming this is left-to-right and top-to-bottom) and backspace moves in the inverse direction. One can also move by dragging the scroll pane around and, finally and most intuitively, by clicking and dragging the text itself in the PostScript view.

Clicking in the PostScript pane will pop up a menu, allowing you to navigate pages, zoom in or out, recenter the page or toggle the visibility of menu bar or the side panel.

It is also possible to drag a list of files from the file manager to the GGv window, making GGv load and display them in different windows.

From the File menu, you can open a new viewing window, open a new document or reload the existing one. You can also close the window (which exits GGv if no more windows exist) or exit the viewer completely.

The Document menu lets you proceed to the next or previous page, recenter the page and set the orientation of the document's pages or zoom to one of the preset magnifications.

In Settings menu you can bring up the Preferences dialog or toggle the visibility of the menu bar and the side panel of the current window.
