Class PopupDialog
- All Implemented Interfaces:
IShellProvider
- Direct Known Subclasses:
DebugPopup
,KeyAssistDialog
Because the dialog is short-lived, most of the configuration of the dialog is done in the constructor. Set methods are only provided for those values that are expected to be dynamically computed based on a particular instance's internal state.
Clients are expected to override the creation of the main dialog area, and may optionally override the creation of the title area and info area in order to add content. In general, however, the creation of stylistic features, such as the dialog menu, separator styles, and fonts, is kept private so that all popup dialogs will have a similar appearance.

Method Details
-
configureShell
Description copied from class:Window
Configures the given shell in preparation for opening this window in it.The default implementation of this framework method sets the shell's image and gives it a grid layout. Subclasses may extend or reimplement.
- Overrides:
configureShell
in classWindow
- Parameters:
shell
- the shell
-
createContents
ThePopupDialog
implementation of thisWindow
method creates and lays out the top level composite for the dialog. It then calls thecreateTitleMenuArea
,createDialogArea
, andcreateInfoTextArea
methods to create an optional title and menu area on the top, a dialog area in the center, and an optional info text area at the bottom. OverridingcreateDialogArea
and (optionally)createTitleMenuArea
andcreateTitleMenuArea
are recommended rather than overriding this method.- Overrides:
createContents
in classWindow
- Parameters:
parent
- the composite used to parent the contents.- Returns:
- the control representing the contents.
-
createDialogArea
Creates and returns the contents of the dialog (the area below the title area and above the info text area.The
PopupDialog
implementation of this framework method creates and returns a newComposite
with standard margins and spacing.The returned control's layout data must be an instance of
GridData
. This method must not modify the parent's layout.Subclasses must override this method but may call
super
as in the following example:Composite composite = (Composite) super.createDialogArea(parent); //add controls to composite as necessary return composite;
- Parameters:
parent
- the parent composite to contain the dialog area- Returns:
- the dialog area control
-
getFocusControl
Returns the control that should get initial focus. Subclasses may override this method.- Returns:
- the Control that should receive focus when the popup opens.
-
setTabOrder
Sets the tab order for the popup. Clients should override to introduce specific tab ordering.- Parameters:
composite
- the composite in which all content, including the title area and info area, was created. This composite's parent is the shell.
-
hasTitleArea
protected boolean hasTitleArea()Returns a boolean indicating whether the popup should have a title area at the top of the dialog. Subclasses may override. Default behavior is to have a title area if there is to be a menu or title text.- Returns:
true
if a title area should be created,false
if it should not.
-
hasInfoArea
protected boolean hasInfoArea()Returns a boolean indicating whether the popup should have an info area at the bottom of the dialog. Subclasses may override. Default behavior is to have an info area if info text was provided at the time of creation.- Returns:
true
if a title area should be created,false
if it should not.
-
createTitleMenuArea
Creates the title and menu area. Subclasses typically need not override this method, but instead should use the constructor parametersshowDialogMenu
andshowPersistAction
to indicate whether a menu should be shown, andcreateTitleControl
to to customize the presentation of the title.If this method is overridden, the returned control's layout data must be an instance of
GridData
. This method must not modify the parent's layout.- Parameters:
parent
- The parent composite.- Returns:
- The Control representing the title and menu area.
-
createTitleControl
Creates the control to be used to represent the dialog's title text. Subclasses may override if a different control is desired for representing the title text, or if something different than the title should be displayed in location where the title text typically is shown.If this method is overridden, the returned control's layout data must be an instance of
GridData
. This method must not modify the parent's layout.- Parameters:
parent
- The parent composite.- Returns:
- The Control representing the title area.
-
createInfoTextArea
Creates the optional info text area. This method is only called if thehasInfoArea()
method returns true. Subclasses typically need not override this method, but may do so.If this method is overridden, the returned control's layout data must be an instance of
GridData
. This method must not modify the parent's layout.- Parameters:
parent
- The parent composite.- Returns:
- The control representing the info text area.
- See Also:
-
fillDialogMenu
Fill the dialog's menu. Subclasses may extend or override.- Parameters:
dialogMenu
- The dialog's menu.
-
showDialogMenu
protected void showDialogMenu()Show the dialog's menu. This message has no effect if the receiver was not configured to show a menu. Clients may call this method in order to trigger the menu via keystrokes or other gestures. Subclasses typically do not override method. -
setInfoText
Set the text to be shown in the popup's info area. This message has no effect if there was no info text supplied when the dialog first opened. Subclasses may override this method.- Parameters:
text
- the text to be shown when the info area is displayed.
-
setTitleText
Set the text to be shown in the popup's title area. This message has no effect if there was no title label specified when the dialog was originally opened. Subclasses may override this method.- Parameters:
text
- the text to be shown when the title area is displayed.
-
getPersistLocation
protected boolean getPersistLocation()Return a boolean indicating whether this dialog will persist its location. This value is initially set in the dialog's constructor, but can be modified if the persist location action is shown on the menu and the user has changed its value. Subclasses may override this method.- Returns:
true
if the dialog's location will be persisted,false
if it will not.- Since:
- 3.4
- See Also:
-
getPersistSize
protected boolean getPersistSize()Return a boolean indicating whether this dialog will persist its size. This value is initially set in the dialog's constructor, but can be modified if the persist size action is shown on the menu and the user has changed its value. Subclasses may override this method.- Returns:
true
if the dialog's size will be persisted,false
if it will not.- Since:
- 3.4
- See Also:
-
open
public int open()Opens this window, creating it first if it has not yet been created.This method is reimplemented for special configuration of PopupDialogs. It never blocks on open, immediately returning
OK
if the open is successful, orCANCEL
if it is not. It provides framework hooks that allow subclasses to set the focus and tab order, and avoids the use ofshell.open()
in cases where the focus should not be given to the shell initially. -
close
public boolean close()Closes this window, disposes its shell, and removes this window from its window manager (if it has one).This method is extended to save the dialog bounds and initialize widget state so that the widgets can be recreated if the dialog is reopened. This method may be extended (
super.close
must be called). -
getDialogSettings
Gets the dialog settings that should be used for remembering the bounds of the dialog. Subclasses should override this method when they wish to persist the bounds of the dialog.- Returns:
- settings the dialog settings used to store the dialog's location
and/or size, or
null
if the dialog's bounds should never be stored.
-
saveDialogBounds
Saves the bounds of the shell in the appropriate dialog settings. The bounds are recorded relative to the parent shell, if there is one, or display coordinates if there is no parent shell. Subclasses typically need not override this method, but may extend it (callingsuper.saveDialogBounds
if additional bounds information should be stored. Clients may also call this method to persist the bounds at times other than closing the dialog.- Parameters:
shell
- The shell whose bounds are to be stored
-
getInitialSize
Description copied from class:Window
Returns the initial size to use for the shell. The default implementation returns the preferred size of the shell, usingShell.computeSize(SWT.DEFAULT, SWT.DEFAULT, true)
.- Overrides:
getInitialSize
in classWindow
- Returns:
- the initial size of the shell
-
getDefaultSize
Return the default size to use for the shell. This default size is used if the dialog does not have any persisted size to restore. The default implementation returns the preferred size of the shell. Subclasses should override this method when an alternate default size is desired, rather than overridinggetInitialSize()
.- Returns:
- the initial size of the shell
- Since:
- 3.4
- See Also:
-
getDefaultLocation
Returns the default location to use for the shell. This default location is used if the dialog does not have any persisted location to restore. The default implementation uses the location computed byWindow.getInitialLocation(Point)
. Subclasses should override this method when an alternate default location is desired, rather than overridinggetInitialLocation(Point)
.- Parameters:
initialSize
- the initial size of the shell, as returned bygetInitialSize
.- Returns:
- the initial location of the shell
- Since:
- 3.4
- See Also:
-
adjustBounds
protected void adjustBounds()Adjust the bounds of the popup as necessary prior to opening the dialog. Default is to do nothing, which honors any bounds set directly by clients or those that have been saved in the dialog settings. Subclasses should override this method when there are bounds computations that must be checked each time the dialog is opened. -
getInitialLocation
Description copied from class:Window
Returns the initial location to use for the shell. The default implementation centers the shell horizontally (1/2 of the difference to the left and 1/2 to the right) and vertically (1/3 above and 2/3 below) relative to the parent shell, or display bounds if there is no parent shell.- Overrides:
getInitialLocation
in classWindow
- Parameters:
initialSize
- the initial size of the shell, as returned bygetInitialSize
.- Returns:
- the initial location of the shell
