SET WINDOW TITLE


SET WINDOW TITLE ( title {; window} )

Parameter	Type	Description
title	String	Window title
window	WinRef	Window reference number, or Frontmost window of current process, if omitted

Description

The SET WINDOW TITLE command changes the title of the window whose reference number is passed in window to the text passed in title (max. length 80 characters).

If the window does not exist, SET WINDOW TITLE does nothing.

If you omit the window parameter, SET WINDOW TITLE changes the title of the frontmost window for the current process.

Note: In the Design environment, 4D changes the window titles automatically —i.e., “Entry for Table” when you perform data entry. If you change a window title, 4D will probably override it. On the other hand, in the Application environment, 4D does not change the titles of the windows.

Example

While performing data entry in a form, you click on a button that executes a lengthy operation (i.e., browsing programmatically related records shown in a subform). You keep informed about the progress of the operation using the title of the current window:

  ` bAnalysis button Object Method

 Case of

    :(Form event=On Clicked)

  ` Save current window title in a local variable

       $vsCurTitle:=Get window title

  ` Start the lengthy operation

       FIRST RECORD([Invoice Line Items])

       For($vlRecord;1;Records in selection([Invoice Line Items]))

          DO SOMETHING

  ` Show progress information

          SET WINDOW TITLE("Processing Line Item #"+String($vlRecord))

       End for

  ` Restore original window title

       SET WINDOW TITLE($vsCurTitle)

 End case
