Usage

From source file:net.sourceforge.squirrel_sql.fw.datasetviewer.cellcomponent.BaseKeyTextHandler.java

/**
 * Ensure, that a sign character is entered at the right position.
 * Valid characters for a sign is the <code>-</code>. If the corresponding {@link ColumnDisplayDefinition#isSigned()} is 
 * <code>false</code>, than a sign is not allowed for this column.
 * Otherwise, a sign character is allowed at the first position of the text if there is not already a sign char present.
 * <B>If the entered sign character is not valid, then the keyEvent will be consumed and a beep will be processed.</B>
 * <p>For example:</p>//from   ww w. j a v  a2 s  .  c o m
 * Allowed:
 * <li>42</li>
 * <li>-42</li>
 * Not allowed:
 * <li>-.42</li>
 * <li>--42</li>
 * <li>42-42</li>
 * <li>-42-42</li>
 * <li>42-</li>
 * @param keyEvent KeyEvent, which insert a character
 * @param textComponent Text component, where the character was typed.
 * @param colDef Display definition of the affected column. This will be used, for finding out, if the data type can be signed.
 * @param beepHelper Helper for beeping, if a sign char is would be inserted at a wrong position.
