boolean

createContents

protected void createContents(org.eclipse.swt.widgets.Composite parent,
                              java.lang.String resourceLabelString,
                              int heightHint)

Creates this object's visual components.

Parameters:

parent - org.eclipse.swt.widgets.Composite

heightHint - height hint for the container selection widget group

getContainerFullPath

public org.eclipse.core.runtime.IPath getContainerFullPath()

Returns the path of the currently selected container or null if no container has been selected. Note that the container may not exist yet if the user entered a new container name in the field.

Returns:

The path of the container, or null

getProblemMessage

public java.lang.String getProblemMessage()

Returns an error message indicating the current problem with the value of a control in the group, or an empty message if all controls in the group contain valid values.

Returns:

java.lang.String

getProblemType

public int getProblemType()

Returns the type of problem with the value of a control in the group.

Returns:

one of the PROBLEM_* constants

getResource

public java.lang.String getResource()

Returns a string that is the name of the chosen resource, or an empty string if no resource has been entered.

The name will include the resource extension if the preconditions are met.

Returns:

The resource name

setResourceExtension(String)

handleEvent

public void handleEvent(org.eclipse.swt.widgets.Event e)

Handles events for all controls in the group.

Specified by:

handleEvent in interface org.eclipse.swt.widgets.Listener

Parameters:

e - org.eclipse.swt.widgets.Event

setAllowExistingResources

public void setAllowExistingResources(boolean value)

Sets the flag indicating whether existing resources are permitted.

Parameters:

value -

setContainerFullPath

public void setContainerFullPath(org.eclipse.core.runtime.IPath path)

Sets the value of this page's container.

Parameters:

path - Full path to the container.

setFocus

public void setFocus()

Gives focus to the resource name field and selects its contents

Sets the value of this page's resource name.

Parameters:

value - new value

setResourceExtension

public void setResourceExtension(java.lang.String value)

Set the only file extension allowed for the resource name field.

If a resource extension is specified, then it will always be appended with a '.' to the text from the resource name field for validation when the following conditions are met:

(1) Resource extension length is greater than 0
(2) Resource name field text length is greater than 0
(3) Resource name field text does not already end with a '.' and the resource extension specified (case sensitive)

The resource extension will not be reflected in the actual resource name field until the resource name field loses focus.

Parameters:

value - The resource extension without the '.' prefix (e.g. 'java', 'xml')

Parameters:

resourcePath - the path to validate

Returns:
