public interface ILaunchConfigurationTab
A launch configuration tab is used to edit/view attributes of a specific type of launch configuration. Launch configurations are presented in a dialog, with a tab folder. Each tab manipulates one ore more attributes of a launch configuration.A tab has the following lifecycle methods:
setLaunchConfigurationDialog(ILaunchConfigurationDialog)
- this is the first method called on a tab after it is instantiated.initializeFrom(ILaunchConfiguration)
- called when a launch configuration is selected to be displayed.activated(ILaunchConfigurationWorkingCopy)
- called when a tab is entered.deactivated(ILaunchConfigurationWorkingCopy)
- called when a tab is exited.performApply(ILaunchConfigurationWorkingCopy)
- called when a tab is to write its values to a launch configuration.dispose()
- the last method called on a tab, when it is to perform any required cleanup. Note that a tab can be disposed before its control has been created.
setDefaults(ILaunchConfigurationWorkingCopy)
can be called before a tab's controls are created.The launch tab framework was originally designed to handle inter tab communication by applying attributes from the active tab to a launch configuration being edited, when a tab is exited, and by initializing a tab when activated. In 3.0, the addition of the methods
activated
anddeactivated
allow tabs to determine the appropriate course of action. The default implementation inAbstractLaunchConfigurationTab
is to call the old methods (initializeFrom
andperformApply
). Tabs should override the new methods as required.This interface is intended to be implemented by clients.

Method Detail
-
createControl
void createControl(Composite parent)
Creates the top level control for this launch configuration tab under the given parent composite. This method is called once on tab creation, aftersetLaunchConfigurationDialog
is called.Implementors are responsible for ensuring that the created control can be accessed via
getControl
- Parameters:
parent
- the parent composite
-
getControl
Control getControl()
Returns the top level control for this tab.May return
null
if the control has not been created yet.- Returns:
- the top level control or
null
-
setDefaults
void setDefaults(ILaunchConfigurationWorkingCopy configuration)
Initializes the given launch configuration with default values for this tab. This method is called when a new launch configuration is created such that the configuration can be initialized with meaningful values. This method may be called before this tab's control is created.- Parameters:
configuration
- launch configuration
-
initializeFrom
void initializeFrom(ILaunchConfiguration configuration)
Initializes this tab's controls with values from the given launch configuration. This method is called when a configuration is selected to view or edit, after this tab's control has been created.- Parameters:
configuration
- launch configuration
-
dispose
void dispose()
Notifies this launch configuration tab that it has been disposed. Marks the end of this tab's lifecycle, allowing this tab to perform any cleanup required.
-
performApply
void performApply(ILaunchConfigurationWorkingCopy configuration)
Copies values from this tab into the given launch configuration.- Parameters:
configuration
- launch configuration
-
getErrorMessage
String getErrorMessage()
Returns the current error message for this tab. May benull
to indicate no error message.An error message should describe some error state, as opposed to a message which may simply provide instruction or information to the user.
- Returns:
- the error message, or
null
if none
-
getMessage
String getMessage()
Returns the current message for this tab.A message provides instruction or information to the user, as opposed to an error message which should describe some error state.
- Returns:
- the message, or
null
if none
-
isValid
boolean isValid(ILaunchConfiguration launchConfig)
Returns whether this tab is in a valid state in the context of the specified launch configuration.This information is typically used by the launch configuration dialog to decide when it is okay to launch.
- Parameters:
launchConfig
- launch configuration which provides context for validating this tab. This value must not benull
.- Returns:
- whether this tab is in a valid state
-
canSave
boolean canSave()
Returns whether this tab is in a state that allows the launch configuration whose values this tab is showing to be saved. This differs fromisValid()
in thatcanSave()
determines if this tab prevents the current launch configuration from being saved, whereasisValid()
determines if this tab prevents the current launch configuration from being launched.This information is typically used by the launch configuration dialog to decide when it is okay to save a launch configuration.
- Returns:
- whether this tab is in a state that allows the current launch configuration to be saved
-
setLaunchConfigurationDialog
void setLaunchConfigurationDialog(ILaunchConfigurationDialog dialog)
Sets the launch configuration dialog that hosts this tab. This is the first method called on a launch configuration tab, and marks the beginning of this tab's lifecycle.- Parameters:
dialog
- launch configuration dialog
-
launched
@Deprecated void launched(ILaunch launch)
Deprecated.As of R3.0, this method is no longer called by the launch framework. Since tabs do not exist when launching is performed elsewhere than the launch dialog, this method cannot be relied upon for launching functionality.Notifies this tab that the specified configuration has been launched, resulting in the given launch. This method can be called when a tab's control does not exist, to support single-click launching.- Parameters:
launch
- the result of launching the current launch configuration
-
getName
String getName()
Returns the name of this tab.- Returns:
- the name of this tab
-
getImage
Image getImage()
Returns the image for this tab, ornull
if none- Returns:
- the image for this tab, or
null
if none
-
activated
void activated(ILaunchConfigurationWorkingCopy workingCopy)
Notification that this tab has become the active tab in the launch configuration dialog.- Parameters:
workingCopy
- the launch configuration being edited- Since:
- 3.0
-
deactivated
void deactivated(ILaunchConfigurationWorkingCopy workingCopy)
Notification that this tab is no longer the active tab in the launch configuration dialog.- Parameters:
workingCopy
- the launch configuration being edited- Since:
- 3.0
-
OkToLeaveTab
default boolean OkToLeaveTab()
Checks if it is OK to leave the Tab.- Returns:
true
if OK to leave the tab orfalse
- Since:
- 3.12
-
postApply
default void postApply()
Perform the changes after apply.- Since:
- 3.12
