| 36 | <p> This example is trivial, and thus useful for
|
|---|
| 37 | investigating problems you might have installing the
|
|---|
| 38 | extension.
|
|---|
| 39 | <p> To build the example, you must first build the
|
|---|
| 40 | <a href="netscape-plugin.html">Qt Netscape Plugin Extension</a> library.
|
|---|
| 41 | Then type <tt>make</tt> in <tt>extensions/nsplugin/examples/trivial/</tt>
|
|---|
| 42 | and copy the resulting <tt>trivial.so</tt> or <tt>nptrivial.dll</tt>
|
|---|
| 43 | to the Plugins directory of your WWW browser.
