Hello Enrico,
I use this turn-around to do it.

Imagine to have a folder oFld with 3 pages: "Folder1","folder2","folder3"

then you can "hide" the folder2 at runtime with:

oFld:SetPrompt("Folder1","","Folder3")
oFld:aEnable[2]:=.f.

Thank you, but I look forward for a better solution.

Enrico,

We need to implement a new method for it, as the dialog for the folder page to hide should be removed from oFld:aDialogs.

We can't simply hide it, as the folder uses the hide and show to select them.

Also, the prompts have to be modified.

I need to create or not, some dialogs depending the rights accesss.
I do this with TPages, but is very similar code:

Add -> DEFAULT aDialogs := {} // In method Redefine

And at dialog creation:

n := 0

DEFINE DIALOG oDlg;
RESOURCE "FICHA";
TITLE "Title"

REDEFINE PAGES oPages;
ID 999;
OF oDlg

If ChkRights() // Check security access

n++
aAdd(aItems, "Datos personales" ) // manually add the dialog
aAdd(oPages:aDialogs, {})

DEFINE DIALOG oPages:aDialogs[n];
RESOURCE "FICHA_01_DATOS01";
OF oPages

REDEFINE GET oGetLegajo;
VAR oDbf:Legajo;
ID 1;
OF oPages:aDialogs[n]

EndIf

This work fine for me.

Best regards!

This seems to work fine:

Code: Select all

FUNCTION FLDHIDEITEM( oFld, nItem )

    LOCAL oDlg := oFld:aDialogs[ nItem ]

    ADEL( oFld:aPrompts, nItem, .T. )
    ADEL( oFld:aDialogs, nItem )

    oFld:aDialogs[ LEN( oFld:aDialogs ) ] = oDlg

    RETURN NIL

Enrico,

I am assuming the third parameter shinks the array? If so, don't you also want to shrink aDialogs?

This function is more like a FldDeleteItem() since you can't decide to later show it again.

Yes.

If so, don't you also want to shrink aDialogs?

No, as the dialog is already active when I decided to hide it. Leaving it working and no visible we avoid a series of problems.

I haven't tried but it should be possible to show it again simply resetting aPrompts and aDialogs to their original values.
