30
31 <p class=MsoNormal style='text-indent:.5in'>GVedit<span style='color:black'> is a
32 Graphviz tool for creating, viewing, editing and processing DOT files. It
33 allows users to set attributes of graphs with dialogue boxes and save them
34 for future use. GVedit users can also take advantage of the simple
35 instant previewing feature of the program.</span></p>

40 style='color:black'>Menu system</span></u></b></p>
41
42 <p class=MsoNormal style='text-indent:.5in'><span style='color:black'>GVedit's main menu bar
43 provides basic file options such as <b>Open</b>, <b>Save</b>, <b>Save As</b> and simple editing
44 operations such as <b>Cut</b>, <b>Copy</b> and <b>Paste</b>. Most of the common commands
45 also have standard keyboard shortcuts.
46 Below you will find a list of the menu items and brief information on
47 each of them.</span></p>

50 <p class=MsoNormal><b><span style='color:black'>File:</span></b></p>
51
52 <p class=MsoNormal style='text-indent:.5in'><span style='color:black'>New: Creates a blank text
53 window. You can use it to write a description of a graph in the DOT language.
54 New graphs are not saved to disk until you save them manually.</span></p>
55
56 <p class=MsoNormal style='text-indent:.5in'><span style='color:black'>Open: Opens a file
57 dialogue box to select and load a DOT file into the editor. Each file is opened in a
58 new window and does not affect other open graphs.</span></p>
59
60 <p class=MsoNormal style='text-indent:.5in'><span style='color:black'>Save: Saves the active
61 graph to disk. If the active graph is new and does not have a name,
62 it opens a <b>Save As</b> dialogue to allow you
63 to specify the file's name before saving.</span></p>
64
65 <p class=MsoNormal style='text-indent:.5in'><span style='color:black'>Save as: Opens a <b>Save As</b>
66 dialogue to save the active graph. You can save a graph under different names but
67 you will always be working with the most recently saved graph.</span></p>
68
69 <p class=MsoNormal style='text-indent:.5in'><span style='color:black'>
70 Close: Closes the active graph window. If there are any unsaved changes,
71 you get a dialogue box asking if you want to
72 save the changes before closing the graph.</span></p>

131 <p class=MsoNormal style='text-indent:.5in'><span style='color:black'>Under the menu bar,
132 there is a toolbar with five buttons on it. These buttons are nothing but shortcuts
133 to some menu items. Each button has a tool tip attached to it to

143 <p class=MsoNormal style='text-indent:.5in'><span style='color:black'>
144 GVedit allows you to have multiple graphs open at the same time. At any
145 time, there is a single active graph.
146 Anything you do using either the GVedit menus or the settings window affects the
147 active graph. When you go to the settings window, you always see the
148 settings of active graph.
149 The settings of each graph are maintained separately.
150 </span></p>
151 <p class=MsoNormal style='text-indent:.5in'><span style='color:black'>
152 To make a graph active, click on its window.
153 The background of the active graph window is white
154 while all others are gray.

161
162 <p class=MsoNormal style='text-indent:.5in'><span style='color:black'>
163 With the settings window,
164 you can select the layout engine, set the output type and file,
165 and set any attributes that are available with the Graphviz release
166 installed on your computer.</span></p>
167
168 <p class=MsoNormal style='text-indent:.5in'><span style='color:black'><b>Layout engine:</b>
169 Graphviz provides five different graph layouts. You can select
170 the one which best fits your needs. More information about these layouts
171 can be found at the <A HREF="http://www.graphviz.org">Graphviz home page</A>
172 </span></p>
173
174 <p class=MsoNormal style='text-indent:.5in'><span style='color:black'><b>Output file name:</b>
175 This field allows you to specify the output file name.
176 You can either type in the name, or use the
177 small button by the text box to open a file
178 dialogue box.
179 This field corresponds to the –o option of Graphviz.
180 </span></p>
181
182 <p class=MsoNormal style='text-indent:.5in'><b><span style='color:black'>Output
183 file type:</span></b><span style='color:black'> This drop down list allows
184 you to select the output file type. The output file name's extension is changed
185 accordingly.
186 This field corresponds to the –T option of Graphviz.
187 </span></p>
188
189 <p class=MsoNormal style='text-indent:.5in'><b><span style='color:black'>Graphviz
190 bin folder:</span></b><span style='color:black'>You usually do not need to
191 enter anything here. During the Graphviz installation, locations of the Graphviz
192 files are stored in the registry and GVedit retrieves it from there. If,
193 for some reason, Graphviz files are not where they are supposed to be
194 and GVedit can not
195 find them, you can edit this information manually.
196 </span></p>
197
198 <p class=MsoNormal style='text-indent:.5in'><b><span style='color:black'>
199 Preview Output file:</span></b><span style='color:black'>
200 If this box is checked,
201 GVedit creates a low-quality preview of the output and shows it in a
202 separate window. It is a convenient way to preview the results without
203 executing another viewing program.
204 </span></p>
205
206 <p class=MsoNormal style='text-indent:.5in'><b><span style='color:black'>
207 Apply cairo filter:</span></b><span style='color:black'>
208 If this output format is supported by the cairo library, this box becomes
209 active. If checked, output will be generated using the cairo library
210 rather than the default renderer.
211 </span></p>
212
213 <p class=MsoNormal style='text-indent:.5in'><b><span style='color:black'>Attributes:</span></b><span style='color:black'>
214 On the lower half of the settings window, you will see two dropdown lists,
215 one small text box, and a larger text editing area. GVedit processes the
216 contents of the large box as additional, generic graph, node or edge attributes.
217 (These correspond to the –G, –N, and –E command-line options of Graphviz.)
218 You can either type directly in the large text box,
219 or use the drop down lists to pick
220 an allowed scope and one of the common attribute names.
221 For details of these attributes, refer to the
222 <A HREF="http://www.graphviz.org/doc/info/attrs.html">page of Graphviz attributes.</A>
223 </span></p>
224
225 <p class=MsoNormal style='text-indent:.5in'><span style='color:black'>
226 If you specify an attribute using the drop down lists, you need to click on the
227 <b>Add</b> button to register the attribute.
228 If you do not click on
229 <b>Add</b> button, the attribute that you entered will not be
230 added to the large box, hence will not be processed.
231 </span></p>
232
233 <p class=MsoNormal style='text-indent:.5in'><span style='color:black'>As an
234 example, assume that we would like to have a graph drawn
235 with a green background.
236 First, click on the scope list and select <b>graph</b>;
237 then click on the name list and
238 select <b>bgcolor</b>; and then type <tt>green</tt> to the value box.
239 Finally, click on the <b>Add</b> button to send the attribute to large box.
240 </span></p>
241
242 <p class=MsoNormal style='text-indent:.5in'><span style='color:black'>
243 Belowe the <b>Add</b> button is a <b>Help</b> button. Clicking on this
244 will open a browser window on the Graphviz page describing the supported
245 attributes.
246 </span></p>
247
248 <p class=MsoNormal style='text-indent:.5in'><span style='color:black'>
249 Under the large box, there are 3 small buttons, plus
250 <b>Cancel</b> and <b>OK</b> buttons. The first button is used to
251 clear the attributes box;
252 the second one is used to load an existing text file into the attributes box;
253 and the last one is used to save the attributes to a text file for later use.
254 The <b>Cancel</b> button closes the window without processing anything;
255 the <b>OK</b> button processes the
256 active document file with the settings on the screen and closes the settings
257 window. If you check the preview check box, you will see the preview of the
258 graph layout on the screen.</span></p>

263 style='color:black'>Console window</span></u></b></p>
264
265 <p class=MsoNormalstyle='text-indent:.5in'><span style='color:black'>
266 At the bottom of the
267 main window, there is a console window where you can see the results of your
268 actions. This provides a trace of your layout actions, showing the
269 Graphviz command corresponding to the active graph's settings. It also
270 displays warnings from GVedit, as well as the output of the
271 executed Graphviz programs.
272 By right clicking on the console window, you will get a menu providing some
273 additional functions, such as clearing or saving the console logs.</span></p>
