HOWTO: How to Display Print Preview in a Top-Level Form

• Microsoft Visual FoxPro for Windows, version 6.0

SUMMARY

Visual FoxPro version 6.0 has added the IN WINDOW clause to make it easier to display the Print Preview window in a top-level form.

MORE INFORMATION

In Visual FoxPro version 5.0, it is not possible to enable the Print Preview to display in a top-level form. The Print Preview window is always displayed in the Visual FoxPro desktop, which is not usually displayed with a top-level form. Visual FoxPro 6.0 has changed this; you can now direct the Print Preview window into an existing top-level form by including the IN WINDOW clause in the report form command. The following code demonstrates how the IN WINDOW clause can work with a top-level form:

Sample Code

   * Start of code example
   *
   public oMain
   oMain = CREATEOBJECT('main')  && open main form
   oMain.visible = .t.
   CREATE TABLE table_1 (field1 C(10))
   FOR lnI=1 TO 3
      INSERT INTO table_1 VALUES ('xx')
   ENDFOR

   CREATE REPORT report_1 FROM table_1

   **************************************************
   *-- Class:        main
   *-- ParentClass:  form
   *-- BaseClass:    form
   *
   DEFINE CLASS main AS form

     Top = 0
     Left = 0
     Height = 165
     Width = 220
     DoCreate = .T.
     Caption = "Main"
     Name = "main"
     opform = .F.

     ADD OBJECT command1 AS commandbutton WITH ;
       Top = 24, ;
       Left = 24, ;
       Height = 37, ;
       Width = 157, ;
       Caption = "Show Print Preview", ;
       Name = "Command1"

     ADD OBJECT command2 AS commandbutton WITH ;
       Top = 84, ;
       Left = 24, ;
       Height = 37, ;
       Width = 157, ;
       Caption = "Close", ;
       Name = "Command2"

     PROCEDURE command1.Click
       oPForm = CREATEOBJECT('printpreview')
       oPform.visible = .t.    && open printpreview form
   *******
   * This is the report form command that uses the IN WINDOW Clause.
   * Notice that it uses both WINDOW and IN WINDOW clauses. The WINDOW
   * clause tells the Print Preview window to take on the characteristics
   * of the window, while IN WINDOW tells in what window to display the
   * Print Preview window.
   *******
    REPORT FORM report_1 PREVIEW WINDOW printpreview IN WINDOW printpreview
    ENDPROC

    PROCEDURE command2.Click
      thisform.release
    ENDPROC

   ENDDEFINE
   *
   *-- EndDefine: main
   **************************************************

   DEFINE CLASS printpreview AS form

     ScaleMode = 3
       Top = 0
       Left = 0
       Height = 454
       Width = 641
       ShowWindow = 2
       DoCreate = .T.
       Caption = "Print Preview Window"
       Movable = .T.
       TitleBar = 0
       WindowState = 0
       SizeBox = .F.
       Name = "printpreview"

   ENDDEFINE
