Code Samples Demonstrate 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.
ENDFOR

*:*************************************************************************

*: 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

ENDDEFINE

   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
ENDDEFINE

*:*************************************************************************
*:
*: 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

ENDDEFINE
