The Applet Locator Information Block

If you are synchronously creating an applet locator using the JMNewAppletLocatorFromInfo function, you must pass an information block that describes the location of the applet. This applet locator structure is defined by the JMLocatorInfoBlock data type.



 
struct JMLocatorInfoBlock {

    UInt32                  fVersion;       

    JMTextRef               fBaseURL;       

    JMTextRef               fAppletCode;    

    short                   fWidth;         

    short                   fHeight;        

    int                     fOptionalParameterCount;    

    JMLIBOptionalParams*    fParams;                    

};

Field descriptions

fVersion: The version of JManager. You should set this field to kJMVersion .
fBaseURL: A text object containing the URL of this applet's host page..
fAppletCode: A text object containing the location of the applet's code (that is, the name of the class file that contains the code). This information is the same as the code location described in an applet tag.
fWidth: The width of the applet, in pixels.
fHeight: The height of the applet, in pixels.
fOptionalParameterCount: The number of optional parameters.
fParams: A pointer to the first element in the array of optional parameters.

The fields fVersion , fBaseURL, fAppletCode, Width, and fHeight must be present and cannot be null values. The other fields are optional and can contain any parameters that need to be passed to the applet for execution. If there are no optional parameters, fOptionalParameterCount should be 0 and fParams should be null.

See the description of the JMNewAppletLocatorFromInfo function JMNewAppletLocatorFromInfo for information on using this strucure.
