\thechapter}}% +\setfooter{\thepage}{}{}{}{}{\thepage}% + +This section describes how you work in the diagram window. + +In addition, you may wish to refer to the following sections: + +\begin{itemize}\itemsep=0pt +\item \helpref{How To}{howto} +%\item \helpref{Getting started}{gettingstarted} +\item \helpref{Using Menu Commands}{menucommands} +\item \helpref{Using Toolbar Commands}{toolbarcommands} +\end{itemize} + +When you first run OGL Studio, there is a menubar, a single +toolbar with commonly-used functionality such as loading and +saving, a project window to the left, and an MDI (Multiple Document +Interface) area to the right, which will contain documents. + +\section{Creating a diagram} + +To create a new diagram, click on "File|New" or the New tool. + +A blank document and two new toolbars will appear. The first +new toolbar is the \helpref{diagramming formatting toolbar}{diagramformattingtoolbar}, and contains +icons and controls for: + +\begin{itemize}\itemsep=0pt +\item alignment and size cloning; +\item arrow toggling; +\item point size; +\item zoom level. +\end{itemize} + +The second new toolbar is called the \helpref{diagram palette}{diagrampalette} and contains: + +\begin{itemize}\itemsep=0pt +\item a pointer tool used for selecting, moving and sizing objects; +\item a text tool used for editing text or creating new text boxes; +\item a tool for each of the symbols. +\end{itemize} + +\section{Basic editing} + +To add a symbol, left-click on the symbol in the diagram palette, +and then left-click on the document. The currently selected +tool will revert to the pointer tool, so to add another object, +click on the symbol again, then on the document. + +To draw a line between two objects, right-drag between the two +objects, starting at the attachment point area you wish to start the +line with, and ending at another appropriate attachment point +area. The initial ordering of the lines may not be correct (lines +may overlap, for example) so to reorder lines on a particular +side of a object, select a line, then left-drag the desired end to a new +position (tip: keep within the object perimeter). Left-dragging the +line end can also be used to change the attachment point of that +end of the line, to a new side or vertex (depending on the object). + +To select or deselect a object, left click the object. To select +several objects at once, keep the shift key pressed down when +left-clicking, or left-drag a 'lassoo' around several objects. + +To delete a object or line, select it and press the Delete key, or use +"Edit|Clear", or right-click on the object to show a menu and choose +the "Cut" item. + +If you are deleting a object which has one ore more lines +attached, the lines are deleted prior to the object deletion. + +Shapes can be rotated by right-clicking and selecting "Rotate +clockwise" or "Rotate anticlockwise". + +Line arrows can be added (pointing in the direction in which +you created the line) by selecting the line and pressing the +"Toggle arrow" tool on the formatting toolbar. + +\section{Adding text} + +Select the text tool (on the symbol palette) and left-click on +a object. If you click outside a object on the document, you are +prompted to add a new free-floating text box. + +Alternatively, you can select a object and press Return (or +select the "Edit|Edit label" menu item); or right-click and +select "Edit label" from the object menu. + +Change the point size using the combobox on the formatting +toolbar. + +\section{Aligning objects} + +Select several objects and click on an alignment tool on +the formatting toolbar. The alignment will be done with +respect to the first object you select. You can also copy +the size of a object to other objects with the "Copy size" tool. + +\section{Adding segments to lines and straightening them} + +To make a line have more than one segment, select the line, +then press the "New line point" tool. Create as many new control points +(and therefore segments) as you like. Then arrange the points +into a rough approximation of how they should be laid out +horizontally and vertically. Click on "Straighten lines" to +tidy up the layout. + +To delete a line control point, select the line and click on +"Cut line point" tool. An arbitrary point will be deleted. + +\section{Undo/Redo} + +Every operation can be undone, and then redone, back until +the time at which you last saved your document. Use +"Edit|Undo" and "Edit|Redo"; or the shortcuts Ctrl-Z and Ctrl-Y. + +\section{Loading and saving files} + +Load and save files using the main toolbar, or "File|Open...", +"File|Save", "File|Save As..." menu items. + +\section{Copy and paste} + +OGL Studio has a diagram clipboard, into which you can copy selections. You can then +paste the contents of clipboard into the same or another diagram window. + +Use "Edit|Copy" (or the toolbar copy button) to copy the selection. Use "Edit|Cut" (or the toolbar cut button) to +copy and then delete the selection. Use "Edit|Paste" (or the toolbar paste button) to copy the selection to +the current diagram window. + +Under Windows, copy and cutting also copies the selection to the Windows clipboard into metafile (vector) +format, and Windows bitmap format. Note that not all Windows applications can accept the vector format. +If the application seems to be pasting the wrong format into the document, try using that application's +"Edit|Paste Special..." menu item, if one exists. + +\section{Keyboard shortcuts} + +The following keyboard shortcuts are available. {\bf Note:} The OGL Studio menus indicate which shortcuts are +available. +
