• Microsoft Visual FoxPro for Windows, version 3.0

SUMMARY

This article provides code that demonstrates how to use the Outline control.

MORE INFORMATION

Code Sample One

In this example, the user selects a database (.dbc file). Then all of its tables, fields, and indexes are listed hierarchically in the outline control.

**** BEGINNING *** *: TEST PUBLIC frm1 frm1=CREA('Myform') frm1.SHOW

FOR i=1 TO frm1.CONTROLCOUNT

   frm1.CONTROLS(i).VISIBLE=.T.

*:************************************************************************* *: *: Class:myform BaseClass: FORM *: *:*************************************************************************

DEFINE CLASS myform AS FORM

   SCALEMODE=3
   WIDTH=600
   HEIGHT=600

   ADD OBJECT CtnOle AS cont1
   ADD OBJECT cmd1 AS cmdbtn

   PROCEDURE INIT
      THISFORM.CtnOle.ole1.ADDITEM('test')
      THISFORM. CtnOle.ole1.ADDITEM('test1')

      THISFORM. CtnOle.ole1.indent(0)=1
      THISFORM. CtnOle.ole1.indent(1)=2
   ENDPROC

*:************************************************************************ *: *: Class:Cont1 BaseClass: CONTAINER *: *:*************************************************************************

DEFINE CLASS Cont1 AS CONTAINER

   WIDTH=400
   TOP=50
   LEFT=50
   HEIGHT=400
   ADD OBJECT ole1 AS OleCtrl

*:************************************************************************* *: *: Class:OleCtrl BaseClass: OLECONTROL *: *:*************************************************************************

DEFINE CLASS OleCtrl AS OLECONTROL

   OLECLASS='MSoutl.outline'
   TOP=60
   LEFT=60
   WIDTH=280
   HEIGHT=250
   VISIBLE=.T.

*:************************************************************************* *: *: Class:cmdbtn BaseClass: COMMANDBUTTON *: *:************************************************************************* DEFINE CLASS cmdbtn AS COMMANDBUTTON

   TOP=80
   LEFT=460
   HEIGHT=30
   WIDTH=100
   VISIBLE=.T.
   CAPTION="Move"

   PROCEDURE CLICK
      THISFORM.CtnOle.ole1.MOVE(120,120,200)
   ENDPROC

Code Sample Two

This example shows how to use the :: operator to call the Outline control's Init event.

**** BEGINNING *** PUBLIC oForm oForm=CREATE('form') oForm.ADDOBJECT('oRedOutl','out1') oForm.oRedOutl.VISIBLE=.T. oForm.oRedOutl.CLICK oForm.SHOW

*:************************************************************************* *: *: Class:out BaseClass: OLECONTROL *: *:************************************************************************* DEFINE CLASS out AS OLECONTROL

   TOP = 24
   LEFT = 24
   HEIGHT = 193
   WIDTH = 289
   OLECLASS='msoutl.outline'

   PROCEDURE INIT
      THIS.ADDITEM('test')
      THIS.ADDITEM('test')
      THIS.ADDITEM('test')
      THIS.ADDITEM('test')
      THIS.ADDITEM('test')
      THIS.ADDITEM('test')
      THIS.indent(0)=1
      THIS.indent(1)=2
      THIS.indent(2)=2
      THIS.indent(3)=2
      THIS.indent(4)=2
      THIS.indent(5)=2
   ENDPROC

*:************************************************************************* *: *: Class:out1 BaseClass: out *: *:************************************************************************* DEFINE CLASS out1 AS out PROCEDURE INIT

      out::INIT
      THIS.OBJECT.BACKCOLOR = RGB(255,0,0)

   ENDPROC

   PROCEDURE CLICK
      WAIT WINDOW
   ENDPROC

For an example of a form (.scx file) that uses the Outline control, please see the Outline1.scx sample form located in the Vfp\Samples\Ole directory.
