Example 3.1. Contextual menus

The example below is pretty useless however it shows how contextual menus can be implemented. It displays a special popup menu when some text is selected and the normal Edit popup menu otherwise.

      <command name="contextualMenu">
        <macro>
          <choice>
            <sequence>
              <test expression="$selectedChars != ''" />
              <command name="contextualMenu1" />
            </sequence>

            <command name="editMenu" />
          </choice>
        </macro>
      </command>

      <command name="contextualMenu1">
        <menu>
          <item label="To Upper Case"
                icon="contextualmenus_icons/to_upper_case.gif"
                command="convertCase" parameter="upper" />
          <item label="To Lower Case"
                icon="contextualmenus_icons/to_lower_case.gif"
                command="convertCase" parameter="lower" />
          <item label="Capitalize Words"
                command="convertCase" parameter="capital" />

          <editMenu />
        </menu>
      </command>

      <binding>
        <mousePressed button="3"/>
        <command name="contextualMenu" />
      </binding>
