Method Details
-
createActivityPromptPref
Create the prompt for activity enablement.- Parameters:
composite
- the parent
-
createContents
Description copied from class:PreferencePage
Creates and returns the SWT control for the customized body of this preference page under the given parent composite.This framework method must be implemented by concrete subclasses. Any subclass returning a
Composite
object whoseLayout
has default margins (for example, aGridLayout
) is expected to set the margins of thisLayout
to 0 pixels.- Specified by:
createContents
in classPreferencePage
- Parameters:
parent
- the parent composite- Returns:
- the new control
-
init
Description copied from interface:IWorkbenchPreferencePage
Initializes this preference page for the given workbench.This method is called automatically as the preference page is being created and initialized. Clients must not call this method.
- Specified by:
init
in interfaceIWorkbenchPreferencePage
- Parameters:
aWorkbench
- the workbench
-
performOk
public boolean performOk()Description copied from interface:IPreferencePage
Notifies that the OK button of this page's container has been pressed.- Specified by:
performOk
in interfaceIPreferencePage
- Overrides:
performOk
in classPreferencePage
- Returns:
false
to abort the container's OK processing andtrue
to allow the OK to happen
-
performDefaults
protected void performDefaults()Description copied from class:PreferencePage
Performs special processing when this page's Defaults button has been pressed.This is a framework hook method for subclasses to do special things when the Defaults button has been pressed. Subclasses may override, but should call
super.performDefaults
.- Overrides:
performDefaults
in classPreferencePage

setInitializationData
Description copied from interface:IExecutableExtension
This method is called by the implementation of the methodIConfigurationElement.createExecutableExtension
on a newly constructed extension, passing it its relevant configuration information. Most executable extensions only make use of the first two call arguments.Regular executable extensions specify their Java implementation class name as an attribute of the configuration element for the extension. For example
<action run="com.example.BaseAction"/>
In the above example, this method would be called with a reference to the
<action>
element (first argument), and"run"
as the name of the attribute that defined this executable extension (second argument).The last parameter is for the specific use of extension adapters and is typically not used by regular executable extensions.
There are two supported ways of associating additional adapter-specific data with the configuration in a way that is transparent to the extension point implementor:
(1) by specifying adapter data as part of the implementation class attribute value. The Java class name can be followed by a ":" separator, followed by any adapter data in string form. For example, if the extension point specifies an attribute
"run"
to contain the name of the extension implementation, an adapter can be configured as<action run="com.example.ExternalAdapter:./cmds/util.exe -opt 3"/>
(2) by converting the attribute used to specify the executable extension to a child element of the original configuration element, and specifying the adapter data in the form of xml markup. Using this form, the example above would become
<action> <run class="com.xyz.ExternalAdapter"> <parameter name="exec" value="./cmds/util.exe"/> <parameter name="opt" value="3"/> </run> </action>
Form (2) will typically only be used for extension points that anticipate the majority of extensions configured into it will in fact be in the form of adapters.
In either case, the specified adapter class is instantiated using its 0-argument public constructor. The adapter data is passed as the last argument of this method. The data argument is defined as Object. It can have the following values:
null
, if no adapter data was supplied- in case (1), the initialization data string is passed as a
String
- in case (2), the initialization data is passed as a
Hashtable
containing the actual parameter names and values (bothString
s)
- Specified by:
setInitializationData
in interfaceIExecutableExtension
- Parameters:
config
- the configuration element used to trigger this execution. It can be queried by the executable extension for specific configuration propertiespropertyName
- the name of an attribute of the configuration element used on thecreateExecutableExtension(String)
call. This argument can be used in the cases where a single configuration element is used to define multiple executable extensions.data
- adapter data in the form of aString
, aHashtable
, ornull
