Syntax

Close([<Window name> [, <Returned value> [... [, <Returned value N>]]]])

<Window name>: Optional character string (with or without quotes)

Name of window to close. If this parameter is not specified or if it corresponds to an empty string (""), the current window is closed.

<Returned value>: Type corresponding to the returned value (optional)

Value returned by the window when it is closed.
This value is retrieved only if the window was opened by Open.

Versions 18 and later
This value is retrieved only if the window was opened by OpenChild.
New in version 18
This value is retrieved only if the window was opened by OpenChild.
This value is retrieved only if the window was opened by OpenChild.
This value is retrieved only if the window was opened by OpenMobileWindow (or by OpenChild).
You have the ability to return:
simple types (character string, boolean, ...).
Versions 15 and later
advanced types: structure, dynamic structure, class, advanced type, array, associative array, queue, stack, list.

Remarks

Codes executed at closing

When closing a window:
1. The current process is permanently interrupted.
2. The "Closing" window event is run.
If ReturnToCapture is called in the "Closing" event, the window is not closed.
If Close is run in a procedure called by Timer, WinStatus or CurrentWin must be used to confirm the existence of the window to close, otherwise all open windows may be closed. For example:

// Procedure called by timer
Window is string
Window = CurrentWin()
IF Window <> "Window name" THEN
Close()
END

Closing according to the type of window

If the window to close is a parent window with child windows, these child windows will be closed first (their closing code is run).
If the window to close is a child window, the parent window becomes the current window. The "gain of focus" code of parent window is run.

Last project window

If the last project window is closed, the "Closing" project event is run before the end of the program.

First project window

Value returned to the Open function

Close can be used to return a value to Open.Close can be used to return one or more values to Open.

Reminder: A value can also be returned by ..ReturnedValue (<Window name>..ReturnedValue) run before Close. In this case, a single value can be returned.

Examples:

The user must type a password in a window. This password is retrieved when this window is closed and it is returned to Open:

MyPassword = Open(WIN_EditPassword)
IF MyPassword <> "" THEN
Info("Wrong password")
END

// -- Click code on "OK" button in the "WIN_EditPassword" window
// The user types his password in the EDT_Password control
// and validates the window.
Close("", EDT_Password)
Versions 19 and later
The user must type a login and a password in a window. The login and password are retrieved when closing this window and they are returned to Open:

(MyLogin, MyPassword) = Open(WIN_EditPassword)
IF MyLogin <> "" OR MyPassword <> "" THEN
Info("Wrong login or password")
END

// -- Click code on "OK" button in the "WIN_EditPassword" window
// The user types his login and password
// in the EDT_Password control and validates the window.
Close("", EDT_Login, EDT_Password)

New in version 19
The user must type a login and a password in a window. The login and password are retrieved when closing this window and they are returned to Open:

(MyLogin, MyPassword) = Open(WIN_EditPassword)
IF MyLogin <> "" OR MyPassword <> "" THEN
Info("Wrong login or password")
END

// -- Click code on "OK" button in the "WIN_EditPassword" window
// The user types his login and password
// in the EDT_Password control and validates the window.
Close("", EDT_Login, EDT_Password)

The user must type a login and a password in a window. The login and password are retrieved when closing this window and they are returned to Open:

(MyLogin, MyPassword) = Open(WIN_EditPassword)
IF MyLogin <> "" OR MyPassword <> "" THEN
Info("Wrong login or password")
END

// -- Click code on "OK" button in the "WIN_EditPassword" window
// The user types his login and password
// in the EDT_Password control and validates the window.
Close("", EDT_Login, EDT_Password)

Versions 18 and later

Value returned when closing a child window

Close is used to return a value to the parent window that opened the child window.

Reminder: A value can also be returned by ..ReturnedValue (<Window name>..ReturnedValue) run before Close.

The value returned by the child window can be read in the event "Closing of a child window" of the window that opened the child window (the one that called OpenChild): Simply use ..ReturnedValue on the MyChildWindow keyword. The value returned by the child window can be read in the event "Closing of a child window" of the window that opened the child window (the one that called OpenMobileWindow or OpenChild): simply use ..ReturnedValue on the MyChildWindow keyword.

For example:

In the closing code of the child window, Close is used to return a parameter:

Close("", MyParameter)
The name of the child window as well as the returned value can be retrieved in the event "Closing a child window" of the calling window, using the MyChildWindow keyword:

// Close a child window
NameChildWindow = MyChildWindow..Name
ValueChildWindow = MyChildWindow..ReturnedValue

New in version 18

Value returned when closing a child window

Close is used to return a value to the parent window that opened the child window.

Reminder: A value can also be returned by ..ReturnedValue (<Window name>..ReturnedValue) run before Close.

For example:

In the closing code of the child window, Close is used to return a parameter:

Close("", MyParameter)
The name of the child window as well as the returned value can be retrieved in the event "Closing a child window" of the calling window, using the MyChildWindow keyword:

// Close a child window
NameChildWindow = MyChildWindow..Name
ValueChildWindow = MyChildWindow..ReturnedValue

Value returned when closing a child window

Close is used to return a value to the parent window that opened the child window.

Reminder: A value can also be returned by ..ReturnedValue (<Window name>..ReturnedValue) run before Close.

For example:

In the closing code of the child window, Close is used to return a parameter:

Close("", MyParameter)
The name of the child window as well as the returned value can be retrieved in the event "Closing a child window" of the calling window, using the MyChildWindow keyword:

// Close a child window
NameChildWindow = MyChildWindow..Name
ValueChildWindow = MyChildWindow..ReturnedValue

Alt + F4 keys

Pressing Alt + F4 can trigger several behaviors:

If the window contains an "Abandon" button, the process associated with the abandon button is run.
If the window contains a button whose shortcut is Alt + F4, the process associated with this button is run.
If the window contains no abandon button and no button whose shortcut is Alt + F4, the closing process of window is run and the window is closed (except if ReturnToCapture is called).
If a window is opened from a program in external language, Alt + F4 returns "ESC" in WdKey.

Equivalence

The following code line:

WinStatus(<WindowName>, NotFound)

is equivalent to:

Close(<WindowName>)
