Richedit( ) function problems

[TimStone]

Many months ago you created a Richedit function and more recently you modified the class. This may have broken elements of the function. In this example:

cTitle := "Test Rich Edit Function"
cText := "this is a test line of the rich edit function. It should be editable very easily"
RichEdit( @cText, cTitle, 0,0,40,200 )

Using this sequence, the following is happening

1) After making changes, and exiting the function, the changes are not saved to a memo field.
2) The icons for position ( left, center, right ), and those that follow on the button bar, are not displaying. The buttons are there but no bitmap display

I thought about using the elements of the new class, but for documentation it says to local at a sample code piece that is very confusing and uses far more than a richedit text

1) Can we get the function fixed so it returns the cText to be saved in a memo field ?
2) Using the PRINT class, can you show me a sample of keeping RTF formatting when printing using @ Row, Column print syntax ( just like I do with a normal memo field )
3) Can we recall and display the RTF in PREVIEW mode ( PRINT class ), and in normal edit field display
4) Can we use the new class with an RC file ( once again, @ x,y syntax doesn't help out with a .rc controlled dialog ).

Tim, last version not modified class TRichedit, new class TRichEdit5 developed and included
Function RichEdit(), not modified in last version, and continue use old version class TRichEdit

OK, but still, the function I described is not fully functional. I've shown the code and noted the problems.

[Silvio.Falconi]

wich error you have?

[TimStone]

Please read the first post in this thread.

Tim
for the old trichedit class
> the changes are not saved to a memo field.
this is a problem I wrote two mounth ago also to Cristobal

Before it run (2002) ok
then Someone changed the save of rtf into Memofile and something not run ok

I would like to make it clear to this someone who should put things as they were and RTF files should be saved to a RTF file and a memo file to a memo file

if the RTF file is stored on a memo file creates the error.
Now I'm trying some functions Reinaldo Reinaldo perhaps has found the solution
because it seems that the function resavefile work good

Tim,

The function RichEdit() was not saving changes previously. In order to save them these changes
are required in memoedit.prg:

Remove static function Save() and modify these lines

static function BuildRichEditBar( oWnd, oRtf, bSave )

...

DEFINE BUTTON oBtn OF oBar ;
MESSAGE "Save a file" TOOLTIP "Save" NOBORDER ;
ACTION If( ! Empty( bSave ), Eval( bSave, oRtf:SaveAsRTF() ),)

...

ACTIVATE DIALOG oDlg CENTERED ;
ON INIT ( BuildRichEditBar( oDlg, oMemo, { | c | cText := c } ), oDlg:ReSize() )

The missing bitmaps are not yet implemented. For now you have to provide these resources
yourself: "Left", "Center", "Right", "Justify", "Number", "Bullet" and "Exit"

These changes will be included in next FWH 16.05

I made the changes ... tried it ... but it's not really going to resolve my problem.

Here is what I want to do. I have some text stored in .fpt memo fields. I want to bring it up in a Rich Text editor, Format it, then save it back to the .fpt file. Then, I want it to print on the final document ( invoice ) in it's modified form. When I bring it up on the screen, I want to also see it in the rich text format.

Do we have a simple sample that shows this created within a dialog ?

[Antonio Linares]

Tim,

Your example with my changes is working fine. What problems do you get ?

cTitle := "Test Rich Edit Function"
cText := "this is a test line of the rich edit function. It should be editable very easily"
RichEdit( @cText, cTitle, 0,0,40,200 )

You have to press the save button in order to save the changes. The saved text is RTF format,
so it can be directly stored in your field.

[Antonio Linares]

I tested your example this way:

Code: Select all  Expand view

#include "FiveWin.ch"

function Main()

   local cTitle := "Test Rich Edit Function"
   local cText := "this is a test line of the rich edit function. It should be editable very easily"

   RichEdit( @cText, cTitle )

   MsgInfo( cText )

return nil

[Antonio Linares]

I have modified function RichEdit() this way so we can know if the text was "saved":

Code: Select all  Expand view

function RichEdit( cText, cTitle, nTop, nLeft, nBottom, nRight )

   local oFont, oDlg, oMemo
   local hDLL
   local uTemp := If( ! Empty( cText ), cText, '' )
   local lRich := .F., lGTF := .F., lSaved := .F.

   DEFAULT nTop := 9, nLeft := 9, nBottom := 27, nRight := 71.5,;
           cTitle := "RichEdit"

   DEFINE FONT oFont NAME "Ms Sans Serif" SIZE 0, -10

   DEFINE DIALOG oDlg FROM nTop, nLeft TO nBottom, nRight ;
      TITLE cTitle FONT oFont
   oDlg:lTruePixel   := .f.

   hDLL  = LoadLibrary( 'riched20.dll' )

   @ 30, 3 RICHEDIT oMemo VAR uTemp OF oDlg PIXEL SIZE 200, 200

   oDlg:oClient = oMemo

   ACTIVATE DIALOG oDlg CENTERED ;
      ON INIT ( BuildRichEditBar( oDlg, oMemo,;
                { | c | lSaved := .T., cText := c } ), oDlg:ReSize() )

   oFont:End()

   if hDLL != nil
      FreeLibrary( hDLL )
   endif

return lSaved

You can test it this way:

Code: Select all  Expand view

#include "FiveWin.ch"

function Main()

   local cTitle := "Test Rich Edit Function"
   local cText := "this is a test line of the rich edit function. It should be editable very easily"

   while RichEdit( @cText, cTitle )
      MsgInfo( cText )
   end  

return nil

It will remain editing the text meanwhile you save it

[TimStone]

OK ... so I use the function, and I take the first 10 words of the text and make them bold.

MsgInfo now shows the text this way:

{\rtf1\ansi\ansicpg1252\deff0\deflang1033{\fonttbl{\f0\fnil\fcharset0 ARIAL;}}
\viewkind4\uc1\pard\b\f0\fs20 I, the Registered Owner hereby authorize the above repair work to be done \b0 along with the necessary materials,

It saved it, but that is what I get instead of I, the Registered Owner hereby authorize the above repair work to be done along with the necessary materials.

[Antonio Linares]

Tim,

What do you get ?

It seems as your msg is uncomplete

[TimStone]

Antonio,

I took the function and placed it in a "full program". The program actually has disclaimer text used on various documents. These are all stored in memo fields in a .dbf/.fpt file. They are all normally edited with a REDEFINE GET cText MEMO ID 2155 OF oDlg . There is no problem. The full text is quite long ( about 20 lines ).

I would like to format these text items as Rich Text, and then save them back to the memo field when completed. So, I added the following button to do the editing:

DEFINE BUTTON oWBtn2 OF oBarS3 RESOURCE "FEEDIT" ;
ACTION ( RichEdit( @cText, cTitle, 0,0,40,200 ), MsgInfo( cText ) )

The first part of the text is:

I, the Registered Owner hereby authorize the above repair work to be done along with the necessary materials.

After using the editor, in MsgInfo() I should get:

I, the Registered Owner hereby authorize the above repair work to be done along with the necessary materials.

Instead it gives me:

{\rtf1\ansi\ansicpg1252\deff0\deflang1033{\fonttbl{\f0\fnil\fcharset0 ARIAL;}}
\viewkind4\uc1\pard\b\f0\fs20 I, the Registered Owner hereby authorize the above repair work to be done \b0 along with the necessary materials,

[Antonio Linares]

Tim,

You get the text in RTF format. You need to display it in a RichEdit control to see it properly.

In my example I use a loop to show the modified text in the same RichEdit() function
