Dynamically adjusting a get field width in a folder

[hua]

For gets on a regular dialog box, I use the following to change their width:

Code: Select all

activate dialog oDlg on init ChgGetsWid(oDlg)

How to specify on init for a folder's page?

TIA

[James Bott]

Have you tried oFolder:bInit?

Hua, James,

the bInit is not executed for the dialogs.

You have to change the method Default(), where the the dialogs are activated and add your own bInit to the standard init.

Stefan,

>the bInit is not executed for the dialogs.

I'm not sure what you mean. Can't you just do something like:

activate dialog oDlg on init oFolder:bInit

Are you saying that oDlg:bInit never gets eval'd?

James,

in the folder class for every page a dialog is created (see Method New() or Redefine() ). These dialogs are activated in the method Default().

Code: Select all

for nLen = 1 to Len( ::aDialogs )
      oDlg = ::aDialogs[ nLen ] 
.....
ACTIVATE DIALOG oDlg NOWAIT ; 
                  ON INIT oDlg:Move( nHeight - 1, 1 ) ; 
                  VALID .f.                // to avoid exiting pressing Esc !!! 
......

As you see there is no self-defined bInit (e.g. oFld:bInit) executed.

A possible solution could be (not tested !)

Code: Select all

ACTIVATE DIALOG oDlg NOWAIT ; 
                  ON INIT (oDlg:Move( nHeight - 1, 1 ), IIF(::bInit!=nil,Eval(bInit),) ) ; 
                  VALID .f.                // to avoid exiting pressing Esc !!!

As Stefan explains, the ON INIT of the folder dialogs is being used, so it replaces a previous existing bInit:

oFolder:aDialogs[ n ]:bInit = { || ... code ... }

so the Stefan solution is right. I suggest it this way:

Code: Select all

ACTIVATE DIALOG oDlg NOWAIT ; 
        ON INIT ( oDlg:Move( nHeight - 1, 1 ),;
        If( oDlg:bInit != nil, Eval( oDlg:bInit, oDlg ),) ) ; 
        VALID .F.

[StefanHaupt]

Yes, you are right

So every page of the folder can have it´s own bInit.

James, Stefan, Antonio,
Thanks for the input . Will give it a try later on
