|
|---|
| 63 | <p> This class is defined in the <b>Qt <a href="activeqt.html#ActiveQt">ActiveQt</a> Extension</b>, which can be found in the <tt>qt/extensions</tt> directory. It is not included in the main Qt API.
|
|---|
| 64 | <p>
|

|
|---|
| 66 | The QAxScript class provides a wrapper around script code.
|
|---|
| 67 |
|
|---|
| 68 |
|
|---|
| 69 | <p> Every instance of the QAxScript class represents a piece of
|
|---|
| 70 | scripting code in a particular scripting language. The code is
|
|---|
| 71 | loaded into the script engine using <a href="#load">load</a>(). Functions declared
|
|---|
| 72 | in the code can be called using <a href="#call">call</a>().
|
|---|
| 73 | <p> The script provides <a href="#scriptEngine">scriptEngine</a>() provides feedback to the
|
|---|
| 74 | application through signals. The most important signal is the
|
|---|
| 75 | <a href="#error">error</a>() signal. Direct access to the <a href="qaxscriptengine.html">QAxScriptEngine</a> is provided
|
|---|
| 76 | through the scriptEngine() function.
|
|---|
| 77 | <p> <b>Warning:</b> This class is not available with the bcc5.5 and MingW
|
|---|
| 78 | compilers.

|
|---|
| 91 | Constructs a QAxScript object called <em>name</em> and registers
|
|---|
| 92 | it with the <a href="qaxscriptmanager.html">QAxScriptManager</a> <em>manager</em>. This is usually done by the

|
|---|
| 95 | <p> A script should always have a name. A manager is necessary to allow
