Constructor Detail

TitleAreaDialog

public TitleAreaDialog(Shell parentShell)

Instantiate a new title area dialog.

Parameters:

parentShell - the parent SWT shell

Method Detail

createContents

protected Control createContents(Composite parent)

Description copied from class: Dialog

The Dialog implementation of this Window method creates and lays out the top level composite for the dialog, and determines the appropriate horizontal and vertical dialog units based on the font size. It then calls the createDialogArea and createButtonBar methods to create the dialog area and button bar, respectively. Overriding createDialogArea and createButtonBar are recommended rather than overriding this method.

Overrides:

createContents in class Dialog

createDialogArea

protected Control createDialogArea(Composite parent)

Creates and returns the contents of the upper part of this dialog (above the button bar).

The Dialog implementation of this framework method creates and returns a new Composite with no margins and spacing. Subclasses should override.

Overrides:

createDialogArea in class Dialog

Parameters:

parent - The parent composite to contain the dialog area

Returns:

the dialog area control

getInitialSize

protected Point getInitialSize()

The TitleAreaDialog implementation of this Window methods returns an initial size which is at least some reasonable minimum.

Overrides:

getInitialSize in class Window

Returns:

the initial size of the dialog

getTitleArea

protected Composite getTitleArea()

Deprecated.

Retained for backward compatibility. Returns the title area composite. There is no composite in this implementation so the shell is returned.

Returns:

Composite

getTitleImageLabel

protected Label getTitleImageLabel()

Returns the title image label.

Returns:

the title image label

setErrorMessage

public void setErrorMessage(String newErrorMessage)

Display the given error message. The currently displayed message is saved and will be redisplayed when the error message is set to null.

Parameters:

newErrorMessage - the newErrorMessage to display or null

setMessage

public void setMessage(String newMessage)

Set the message text. If the message line currently displays an error, the message is saved and will be redisplayed when the error message is set to null.

Shortcut for setMessage(newMessage, IMessageProvider.NONE)

This method should be called after the dialog has been opened as it updates the message label immediately.

Parameters:

newMessage - the message, or null to clear the message

setMessage

public void setMessage(String newMessage,
                       int newType)

Sets the message for this dialog with an indication of what type of message it is.

The valid message types are one of NONE, INFORMATION,WARNING, or ERROR.

Note that for backward compatibility, a message of type ERROR is different than an error message (set using setErrorMessage). An error message overrides the current message until the error message is cleared. This method replaces the current message and does not affect the error message.

Parameters:

newMessage - the message, or null to clear the message

newType - the message type

Since:

2.0

public void setTitle(String newTitle)
