Richedit enhancement

[Gianni]

Hi Antonio,
are you thinking about implementing "PARAFORMAT" indenting in richedit control ?

Gianni,

the structure PARAFORMAT is already supported, see method ::SetParaFormat ()

[Gianni]

Stefan,

where is ::SetParaFormat () method?
I cannot found it in my Trichedi.prg
My version is FWH 8.05

Gianni,

Here you have an example of its use in Class TRichEdit:

Code: Select all

METHOD SetAlign( nAlign ) CLASS TRichEdit

   DEFAULT nAlign := PFA_LEFT

   RESetParaFormat( ::hWnd, nAlign )

   ::Change()

return nil

Thanks Antonio, but I already know this.
I'm not talking about "align" support, but "indenting" support; so I can implement a ruler like "WordPad".
At this time there is no support for "paraformat" member in bold:

typedef struct _paraformat {
UINT cbSize;
DWORD dwMask;
WORD wNumbering;
WORD wReserved;
LONG dxStartIndent;
LONG dxRightIndent;
LONG dxOffset;
WORD wAlignment;
SHORT cTabCount;
LONG rgxTabs[MAX_TAB_STOPS];
} PARAFORMAT;

Another question:
If I open, for example, fiveodbc.rtf included in folder samples, all grids are wrong. Have you this problem too?

Oops, should be ReSetParaFormat () as Antonbio said. Sorry.

Gianni,

Grids seem ok here:


You can easily modify RESETPARAFORMAT() to support those struct members:

Code: Select all

HB_FUNC( RESETPARAFORMAT )
{
   PARAFORMAT pf;

   memset( ( char * ) &pf, 0, sizeof( pf ) );

   pf.cbSize = sizeof( pf );
   pf.dwMask = PFM_ALIGNMENT;
   pf.wAlignment |= hb_parnl( 2 );

   hb_retl( SendMessage( ( HWND ) hb_parnl( 1 ), EM_SETPARAFORMAT, 0,
                         ( LPARAM ) &pf ) );
}

Gianni,

this seems ok, but if you go a little forward (about half rtf) you can see another grid, with longer text inside, that don't resize its height to contain all text. Compare it opening same rtf with WordPad

You can easily modify RESETPARAFORMAT() to support those struct members:

Code: Select all

HB_FUNC( RESETPARAFORMAT )
{
   PARAFORMAT pf;

   memset( ( char * ) &pf, 0, sizeof( pf ) );

   pf.cbSize = sizeof( pf );
   pf.dwMask = PFM_ALIGNMENT;
   pf.wAlignment |= hb_parnl( 2 );

   hb_retl( SendMessage( ( HWND ) hb_parnl( 1 ), EM_SETPARAFORMAT, 0,
                         ( LPARAM ) &pf ) );
}

Thanks.
So, are you not implementing anything about this in near future?

Gianni,

We are going to provide new enhancements for Class TRichEdit, and we will probably implement this too

[Gianni]

Great!!!
I will waiting for it.

Many thanks
