Tab Order

[sajith]

Hello,can any one help me

How can i Set the tab order of control by code.iam not using Resource for designing .

Regards,

Sajith,

The focus will be set by the order that you use to create the controls, i.e.:

Code: Select all

#include "FiveWin.ch"  
 
function Main()        
 
   local oDlg, cFirst := Space( 20 ), cLast := Space( 20 )        
 
   DEFINE DIALOG oDlg TITLE "Test"        
 
   @ 1, 1 GET cFirst
   
   @ 2, 1 GET cLast
 
   ACTIVATE DIALOG oDlg CENTERED  
 
return nil 
 

Now, to reverse that focus sequence, we first create the second GET:

Code: Select all

#include "FiveWin.ch"  
 
function Main()        
 
   local oDlg, cFirst := Space( 20 ), cLast := Space( 20 )        
 
   DEFINE DIALOG oDlg TITLE "Test"        

   @ 2, 1 GET cLast
 
   @ 1, 1 GET cFirst
 
   ACTIVATE DIALOG oDlg CENTERED  
 
return nil

many many thanks for ur support,

My pblm is for example :

Code: Select all

#include "FiveWin.ch"  
 
function Main()        
 
   local oDlg, cFirst := Space( 20 ), cLast := Space( 20 )        
 
   DEFINE DIALOG oDlg TITLE "Test"        

   @ 1, 1 GET cLast
 
   @ 2, 1 GET cFirst

  @ 4, 1 GET cFirst

  @ 5, 1 GET cFirst

  @ 6, 1 GET cFirst

  @ 7, 1 GET cFirst

  @ 8, 1 GET cFirst

   @ 3, 1 GET cFirst //3 rd control 
 
   ACTIVATE DIALOG oDlg CENTERED  
 
return nil 

 

in the above code i added 3rd contol in the last line i want to set the Tab position of that control to 3. how it is possible

Dear Mr.Sajith,

in the above code i added 3rd contol in the last line i want to set the Tab position of that control to 3 . how it is possible

That is what Mr.Antonio has explained. TAB order will work as per the order in which the control is defined/created in your PRG. While coding you have to decide and then write the code accordingly.

Code: Select all

#include "FiveWin.ch"  
 
function Main()        
 
   local oDlg, cFirst := Space( 20 ), cLast := Space( 20 )       
   Local oGet1, oGet2, oGet3, oGet4, oGet5, oGet6, oGet7, oGet8
   Local cVar1, cVar2, cVar3, cVar4, cVar5, cVar6, cVar7, cVar8
 
   DEFINE DIALOG oDlg TITLE "Test"        

   @ 1, 1 GET oGet1 VAR cGet1
 
   @ 2, 1 GET oGet2 VAR cGet2

  @ 3, 1 GET oGet3  VAR cGet3 //3 rd control , moved from last line

  @ 4, 1 GET oGet4 VAR cGet4

  @ 5, 1 GET oGet5 VAR cGet5

  @ 6, 1 GET oGet6 VAR cGet6

  @ 7, 1 GET oGet7 VAR cGet7

  @ 8, 1 GET oGet8 VAR cGet8

 
   ACTIVATE DIALOG oDlg CENTERED  
 
return nil

If you want oGet6 to receive the first focus then you should define oGet6 first, then oGet1, oGet2, oGet3 etc.

Code: Select all

@ 6, 1 GET oGet6 VAR cGet6
@ 1, 1 GET oGet1 VAR cGet1
@ 2, 1 GET oGet2 VAR cGet2
 

Hope it is clear to you.

it will be very difficult and time consuming if we need to alter the structure of Design after all coding is finished .

Dear Mr.Sajith,

it will be very difficult and time consuming if we need to alter the structure after all coding is finished

It is just a matter of moving the Get declaration statement in the prg 1 or 2 line above or below. I don't think it is that difficult.

For eg. see how I changed the tab order based on the example which I posted earlier. The Get objects TAB order changed from 6,1,2 to 2,6, 1

Code: Select all

@ 2, 1 GET oGet2 VAR cGet2
@ 6, 1 GET oGet6 VAR cGet6
@ 1, 1 GET oGet1 VAR cGet1

Pls view the below Function ::
Suppose if i add a new control in 24 th position i need to alter position of all control.
Hope u got me

Dear Sajith,

It all depends on the style of the coding which you adopt. Since you have hard coded the oDlg:aControls[nNo] it may be confusing to you to change the order. If I were to write the code, I would not have used that technique and would have opted some other way, so that editing of the TAB order does not cause too much of complications and does not force me to re-check/alter the whole code in my PRG.

While coding, I always keep in my mind that my client's requirements may change on a later date and I may have to alter the code, and a small change in a code should not create a havoc and should not invite unwanted problems into my app.

Many Many thanks for ur Wise suggestion ,

can u Pls help me to find a better way to extract the Specific controls(Object) from a Dialog so that it will be really help full for me .

Code: Select all

Dear Sajith,

I understand that you are passing the Dialog as parameter to the function and using aControls to extract the values from the controls. In your code you are using oDlg:aControls[] referenced by the array subscript no., the subscript no. of the controls changes when you change the order of the controls creation (ie when you wish to change the TAB order etc).

There are different ways to achieve this and one method is that you can use an array to hold the GET controls and then you could have passed the array as parameter to function. Here other well experienced gurus are available in this forum who may be able to give you much better ideas.

Code: Select all

Local aMyControls:={nil,nil,nil,nil,nil,nil,nil} 
...
...

@02.3,10 getaMyControls[1] VAR cVar1
@03.4,10 get aMyControls[2] VAR cVar2
@04.5,10 get aMyControls[3] VAR cVar3
@05.6,10 get aMyControls[4] VAR cVar4
@06.7,10 get aMyControls[5] VAR cVar5
@07.8,10 get aMyControls[6] VAR cVar6

There are other user class named TPublic etc available which can be used instead of using array to hold the controls. If you use the TPublic class, you will be able to refer to the controls in a much meaningful way.

For. eg.

Code: Select all

oMyControl:=TPublic():New(.T.)

oMyControl:cUserName1:=Space(30)   // Used to hold data while Adding New User
oMyControl:cPassword1:=Space(10)   // Used to hold data while Adding New User
oMyControl:nStatus1  :=1           // Used to hold data while Adding New User

oMyControl:oUserName1:=NIL   // Used to hold Objects while Adding New User
oMyControl:oPassword1:=NIL   // Used to hold Objects while Adding New User
oMyControl:oStatus1  :=NIL   // Used to hold Objects while Adding New User

@01.1,05 get oMyControl:oUserName1 VAR oMyControl:cUserName1 of ..
@02.3,05 get oMyControl:oPassword1 VAR oMyControl:cPassword1 of ...
@03.4,05 RADIO oMyControl:oStatus1 VAR oMyControl:nStatus1 of oFolder:aDialogs[1] ;
         ITEMS "Enabled","Disabled"  Update

Hope you understand what I am trying to explain to you.

Sajith,

If you are using a DBF to store this data, then it is simple to use a database object. To clear all the fields you simply do:

oPaySlip:blank()
oDlg:refresh()

This is much simpler than your approach. All the data is held in an array and calling the blank() method refills the array with blank data.

You can read more about using database objects in some articles that I wrote which are available on my website at http://www.gointellitech.com.

Hi anserkk,

Code: Select all

oMyControl:=TPublic():New(.T.)
 

Where can I find the TPublic class?

Thanks

[James Bott]

I suggest rather than using TPublic either using a database class or creating your own class for the object. The database class will automatically create data for all the fieldnames.

Sajith,

If you need to give the focus to a specific control then you can do it this way:

Code: Select all

#include "FiveWin.ch"  
 
function Main()        
 
   local oDlg, cFirst := Space( 20 ), cLast := Space( 20 ) 
 
   DEFINE DIALOG oDlg TITLE "Test"        
 
   @ 1, 1 GET cFirst
   
   @ 2, 1 GET cLast
 
   ACTIVATE DIALOG oDlg CENTERED ;
      ON INIT ( oDlg:aControls[ 2 ]:SetFocus(), .F. )
 
return nil 
 

Please notice that .F. must be returned from the ON INIT clause to tell Windows that we are changing the focus sequence order using Method SetFocus()
