|
52 |
* This functionality is carried out thanks to two tabs (simple line and arrow

|
54 |
* (SymbolEditor)how is explained in AbstractTypeSymbolEditor.<p>
|

|
56 |
* The first tab (Simple Line)allows the user to change the color (<b>jccColor</b>),

57 |
* the width (<b>txtWidth</b>) and the style of the line (<b>cmbLinStyles</b>).<p>
|
58 |
* <p>
|
59 |
* The second tab (<b>arrowDecorator</b>)allows the user to insert a symbol in the
|
60 |
* line (for example an arrow to specify its orientation)and to modify it.
