Calling this property has no impact on the functionality. However, it has impact on the position and size of the control in a DataWindow when the DataWindow is zoomed in or zoomed out. Refer to the detailed information below.

DETAILED INFORMATION

Location: Of_setresize(boolean) function of pfc_w_master in pfcmain.pbl

Appeon Unsupported Code: Lcd_class = this.ClassDefinition

Line Number: 45

Change the code to:

if AppeonGetClientType( ) = 'PB' then
 classdefinition lcd_class
 lcd_class = this.ClassDefinition   
 li_vars = UpperBound ( lcd_class.VariableList )
 For li_v = 1 to li_vars
  If lcd_class.VariableList[li_v].Name = "width" then &
   li_origwidth = Integer ( lcd_class.VariableList[li_v].InitialValue ) 
  If lcd_class.VariableList[li_v].Name = "height" then &
   li_origheight = Integer ( lcd_class.VariableList[li_v].InitialValue ) 
  If li_origwidth > 0 And li_origheight > 0 then &
  Exit
Next
 inv_resize.of_SetOrigSize ( li_origwidth, li_origheight )
else
 inv_resize.of_SetOrigSize ( this.width, this.height )
end if

PowerObject

Classdefinition

7

Need modification

This property is often used for detecting a function of a object.

It is suggested to modify the whole code segment, calling a function no matter whether it exists or not. Refer to the detailed information below.

DETAILED INFORMATION

Location 1: Of_validation(powerobject) function of pfc_n_cst_luw in pfcapsrv.pbl

Appeon Unsupported Code: Lcd_class = this.ClassDefinition

Line Number: 123

Change the code to:

if AppeonGetClientType( ) = 'PB' then
  lb_defined = inv_metaclass.of_isFunctionDefined 
  & (lpo_tocheck.ClassDefinition, "of_Validation", ls_args)
else
  lb_defined = True
End if

Location 2: Of_updatespending(powerobject) function of pfc_n_cst_luw in pfcapsrv.pbl

Appeon Unsupported Code: Lb_defined = inv_metaclass.of_isFunctionDefined (lpo_tocheck.ClassDefinition, "of_UpdatesPending", ls_args)

Line Number: 130

Change the code to:

if AppeonGetClientType( ) = 'PB' then
  lb_defined = inv_metaclass.of_isFunctionDefined 
  & (lpo_tocheck.ClassDefinition, "of_UpdatesPending", ls_args)
Else
 lb_defined = True
End if

Location 3: Of_updateprep(powerobject) function of pfc_n_cst_luw in pfcapsrv.pbl

Appeon Unsupported Code: Lb_defined = inv_metaclass.of_isFunctionDefined (lpo_tocheck.ClassDefinition, "of_UpdatePrep", ls_args)

Line Number: 122

Change the code to:

if AppeonGetClientType( ) = 'PB' then
  lb_defined = inv_metaclass.of_isFunctionDefined 
  & (lpo_tocheck.ClassDefinition, "of_UpdatePrep", ls_args)
else
  lb_defined = True
End if

Location 4: Of_update(powerobject,boolean,boolean) function of pfc_n_cst_luw in pfcapsrv.pbl

Appeon Unsupported Code: Lb_defined = inv_metaclass.of_isFunctionDefined (lpo_tocheck.ClassDefinition, "of_Update", ls_args)

Line Number: 145

Change the code to:

if AppeonGetClientType( ) = 'PB' then
  lb_defined = inv_metaclass.of_isFunctionDefined 
  & (lpo_tocheck.ClassDefinition, "of_Update", ls_args)
Else
  lb_defined = True
End if

However, with the suggested changes made, only DataWindows placed directly on windows would update. For DataWindows placed on tab pages to update correctly, add the code to the Case statement in the function to call of_update() on UserObject and Tab controls to make updates on tab pages work correctly.

Location 5: Of_postupdate(powerobject) function of pfc_n_cst_luw in pfcapsrv.pbl

Appeon Unsupported Code: Lb_defined = inv_metaclass.of_isFunctionDefined (lpo_tocheck.ClassDefinition, " of_PostUpdate ", ls_args)

Line Number: 123

Change the code to:

if AppeonGetClientType( ) = 'PB' then
  lb_defined =inv_metaclass.of_isFunctionDefined 
  & (lpo_tocheck.ClassDefinition, "of_PostUpdate", ls_args)
else
  lb_defined = True
End if

Location 6: Of_isselfupdatingobject(powerobject) function of pfc_n_cst_luw in pfcapsrv.pbl

Appeon Unsupported Code: Lb_defined = inv_metaclass.of_isFunctionDefined (apo_control.ClassDefinition, "of_Update", ls_args)

Line Number: 60

Change the code to:

if AppeonGetClientType( ) = 'PB' then
  lb_defined =inv_metaclass.of_isFunctionDefined 
  & (apo_control.ClassDefinition, "of_Update", ls_args)
else
  lb_defined =True
End if

Location 7: Of_accepttext(powerobject,boolean) function of pfc_n_cst_luw in pfcapsrv.pbl

Appeon Unsupported Code: Lb_defined = inv_metaclass.of_isFunctionDefined (lpo_tocheck.ClassDefinition, "of_AcceptText", ls_args)

Line Number: 128

Change the code to:

if AppeonGetClientType( ) = 'PB' then
  lb_defined = inv_metaclass.of_isFunctionDefined 
  & (lpo_tocheck.ClassDefinition, "of_AcceptText", ls_args)
else
  lb_defined = True
End if

Need modification.

Refer to the detailed information below.

Location: Of_position(dragobject,boolean) function of pfc_n_cst_dropdown in pfcapsrv.pbl

Appeon Unsupported Code: If ldw_object.hsplitscroll

Line Number: 237

Change the code to:

if AppeonGetClientType( ) = 'PB' then
 li_hsplit = Integer (ldw_object.Describe ("DataWindow.HorizontalScrollSplit"))
 li_hpos1 = Integer (ldw_object.Describe ("DataWindow.HorizontalScrollPosition"))
 li_hpos2 = Integer (ldw_object.Describe ("DataWindow.HorizontalScrollPosition2"))
  if ldw_object.hsplitscroll then
   if li_hsplit > 4 and li_pointerx > li_hsplit then
    li_hpos = li_hpos2 - li_hsplit - of_GetSystemSetting (DW_HSPLITBAR_WIDTH)
   else
    li_hpos = li_hpos1
   End if
  else
   li_hpos = li_hpos1
