<h2>Introduction</h2>
|
|
|
|
|
|
<p>This document will guide you through the application and help to familiarize
|
|
|
|
|
|
you with it. The description of tasks mainly targets the Microsoft Windows
|
|
|
|
|
|
operating system, though it’s also valid for other operating systems to
|
|
|
|
|
|
a certain extent.
|
|
|
|
|
|
|
|
|
|
|
|
<h2>Getting the application</h2>
|
|
|
|
|
|
<p>Download the newest version of the application at the following web address:
|
|
|
|
|
|
<a href="https://git.janouch.name/p/logdiag">https://git.janouch.name/p/logdiag</a>.
|
|
|

|
<br>Figure 1: The download menu on the project site
|
|
|
|
|
|
|
|
|
|
|
|
<p>While on the web, look for a tab entitled <q>Releases</q> and click on it.
|
|
|
|
|
|
A list of versions will appear with files for download listed under
|
|
|
|
|
|
<q>Downloads</q> headings. The installation file for Microsoft Windows is named
|
|
|
|
|
|
in the style of <q>logdiag-<i>version</i>-Windows-x86.exe</q>.
|
|
|
|
|
|
|
|
|
|
|
|
<h2>Installation</h2>
|
|
|
|
|
|
<p>The installation process is quite straight-forward. After the initial screen
|
|
|
|
|
|
a license agreement is required. Next, choose a folder in which to install
|
|
|
|
|
|
the application and another one for placement in the Start menu. So long as
|
|
|
|
|
|
no unexpected errors have occurred, all that’s left is confirming a successful
|
|
|
|
|
|
installation.
|
|
|
|
|
|
|
|
|
|
|
|
<p><b>Warning</b>: If the application is installed into a folder where
|
|
|
|
|
|
a previous installation is already located, problems may arise. Although it is
|
|
|
|
|
|
possible to do so, don’t try to install multiple copies parallely either, for
|
|
|
|
|
|
the same reasons. Remove the current installation first, for example by using
|
|
|
|
|
|
the shortcut located in the Start menu.
|
|
|
|
|
|
|
|
|
|
|
|
<h2>Operations with objects</h2>
|
|
|
|
|
|
<p>Each diagram consists of objects, and these are accompanied by the operations
|
|
|
|
|
|
described below. To cancel any current operation, press the Escape key.
|
|
|
|
|
|
|
|
|
|
|
|
<!-- TODO: see the Czech version -->
|
|
|
|
|
|
|
|
|
|
|
|
<h3>Selecting objects</h3>
|
|
|
|
|
|
<p>Select single objects by left-clicking on them. They will get highlighted
|
|
|
|
|
|
with red color in reaction to this. To select multiple objects, hold the Shift
|
|
|
|
|
|
key while clicking.
|
|
|
|

|
|
<br>Figure 2: Selecting objects inside an area
|
|
|
|
|
|
|
|
|
|
|
|
<p>Alternatively drag the mouse from free space within the diagram into
|
|
|
|
|
|
the area, see <a href="#select-objects">Figure 2</a>. Objects contained in this
|
|
|
|
|
|
rectangle will be selected. The selection may later be dismissed by just
|
|
|
|
|
|
clicking into free space.
|
|
|
|
|
|
|
|
|
|
|
|
<h3>Moving objects</h3>
|
|
|
|
|
|
<p>Moving of objects is done by dragging them with the mouse onto the desired
|
|
|
|
|
|
place. If these objects form a part of the current selection, the whole
|
|
|
|
|
|
selection is moved. The selection may also be moved using cursor keys.
|
|
|
|
|
|
|
|
|
|
|
|
<h3>Removing objects</h3>
|
|
|
|
|
|
<p>Remove objects either by pressing the Delete key or from the application
|
|
|
|
|
|
menu.
|
|
|
|
|
|
|
|
|
|
|
|
<h3>Inserting symbols</h3>
|
|
|
|
|
|
<p><i>Symbols</i> constitute the most important kind of objects. Insert them
|
|
|
|
|
|
into the diagram by choosing one from the symbol menu located on the left side
|
|
|
|
|
|
of the main application window and dragging it onto the diagram where you want
|
|
|
|
|
|
the symbol to be placed.
|
|
|
|
|
|
|
|
|
|
|
|
<h3>Rotating symbols</h3>
|
|
|
|
|
|
<p>Rotate a symbol inserted into the diagram by right-clicking on it.
|
|
|
|
|
|
|
|
|
|
|
|
<h3>Connecting terminals</h3>
|
|
|
|
|
|
<p>A point intended for creation of connections between symbols or other
|
|
|
|
|
|
connections is called a <i>terminal</i>. To lead a connection out of it, first
|
|
|
|
|
|
hover it with the mouse pointer, so it gets visibly highlighted with a circle.
|
|
|
|
|
|
Then press the left mouse button and drag the pointer onto the place where you
|
|
|
|
|
|
want the connection to end.

<h2>Frequent problems</h2>
|
|
|
|
|
|
<h3>Can’t open a saved diagram</h3>
|
|
|
|
|
|
<p>When saving, ensure that the filename you’ve typed in contains the
|
|
|
|
|
|
<q>.ldd</q> suffix. If not, it won’t show up in the dialog for opening diagrams.
|
|
|
|
|
|
In case you’ve already saved a file without an extension, you may fix this
|
|
|
|
|
|
situation by adding the suffix to its name.
|
|
|
|
|
|
|
|
|
|
|
|
<h3>I miss labels</h3>

|
|
|
|
<p>This functionality doesn't exist yet, but it is possible to get around this
|
|
|
|
|
|
limitation either by using the PrintScreen key to capture a screenshot
|
|
|
|
|
|
and inserting it to, for example, Paint, or similarly by adding your texts
|
|
|
|
|
|
to a <q>printed</q> PDF file.
