canSave

public boolean canSave()
Description copied from interface: ILaunchConfigurationTab
Returns whether this tab is in a state that allows the launch configuration whose values this tab is showing to be saved. This differs from isValid() in that canSave() determines if this tab prevents the current launch configuration from being saved, whereas isValid() 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.

Specified by:
canSave in interface ILaunchConfigurationTab

whether this tab is in a state that allows the current launch configuration to be saved
See Also:
ILaunchConfigurationTab.canSave()

isValid

public boolean isValid(
ILaunchConfiguration launchConfig)
Description copied from interface: ILaunchConfigurationTab
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.

Specified by:
isValid in interface ILaunchConfigurationTab
Parameters:
launchConfig - launch configuration which provides context for validating this tab. This value must not be null.
Returns:
whether this tab is in a valid state
See Also:
ILaunchConfigurationTab.isValid(ILaunchConfiguration)

createVerticalSpacer

protected void setAttribute(
String attribute,

activated

public void activated(
ILaunchConfigurationWorkingCopy workingCopy)
This method was added to the ILaunchConfigurationTab interface in the 3.0 release to allow tabs to distinguish between a tab being activated and a tab group be initialized for the first time, from a selected launch configuration. To maintain backwards compatible behavior, the default implementation provided, calls this tab's initializeFrom method. Tabs should override this method as required.

The launch tab framework was originally designed to take care of inter tab communication by applying attributes from the active tab to the launch configuration being edited, when a tab is exited, and by initializing a tab when activated. The addition of the methods activated and deactivated allow tabs to determine the appropriate course of action.

Specified by:
activated in interface ILaunchConfigurationTab
Parameters:
workingCopy - the launch configuration being edited
Since:
3.0
See Also:
ILaunchConfigurationTab.activated(org.eclipse.debug.core.ILaunchConfigurationWorkingCopy)

deactivated

public void deactivated(
ILaunchConfigurationWorkingCopy workingCopy)
This method was added to the ILaunchConfigurationTab interface in the 3.0 release to allow tabs to distinguish between a tab being deactivated and saving its attributes to a launch configuration. To maintain backwards compatible behavior, the default implementation provided, calls this tab's performApply method. Tabs should override this method as required.
