FWH MGET control 'GoBottom()' method does not work

[peterk]

Antonio
This appears to be a bug
16 bit works correctly and the Mget control displays the text at the bottom and scrolls the vertical scroll bar to the bottom (same as TWBrowse), but 32 bit does not, it seems to ignore the message

Please can you check and advise

Extract of code below:
//-----------------------------------------------------------------------------------METHOD AddToLog ( pcItem ) CLASS qFileSnd
/*
Purpose
Add a line to the log mget
*/

::cLog += Time() + ": " + pcItem + CRLF
::oMGet:SetText( ::cLog )
::oMget:GoBottom()

RETURN .t.

Peter,

This test works ok, could you please check it there and confirm us if it works ok for you ? thanks

Code: Select all  Expand view

#include "Fivewin.ch"

FUNCTION MAIN()

    LOCAL oDlg
    LOCAL oGet, cVar := "Hello World!" + CRLF + "This is a test"

    DEFINE DIALOG oDlg

    @ 1, 1 GET oGet VAR cVar MEMO SIZE 80, 30

    @ 3, 1.5 BUTTON "&Close";
           ACTION oDlg:End()

    @ 3, 8.5 BUTTON "&Bottom";
           ACTION ( oGet:GoBottom(), oGet:SetFocus() )

    ACTIVATE DIALOG oDlg ;

Hi Antonio
Please try the followiing:

FUNCTION MAIN()

LOCAL oDlg
LOCAL oGet, cVar := "Hello World!" + CRLF + "This is a test"

cVar += CRLF + "Line 2"
cVar += CRLF + "Line 3"
cVar += CRLF + "Line 4"
cVar += CRLF + "Line 5"
cVar += CRLF + "Line 6"
cVar += CRLF + "Line 7"
cVar += CRLF + "Line 8"
cVar += CRLF + "Line 9"
cVar += CRLF + "Line 10"


DEFINE DIALOG oDlg

@ 1, 1 GET oGet VAR cVar MEMO SIZE 80, 30

@ 3, 1.5 BUTTON "&Close";
ACTION oDlg:End()

@ 3, 8.5 BUTTON "&Bottom";
ACTION ( oGet:GoBottom(), oGet:SetFocus() )

ACTIVATE DIALOG oDlg ;
CENTER

RETURN NIL

Peter,

Yes, I see what you mean. The GET is not scrolling down in 32 bits. In 16 bits it works fine and its the same code.

We are going to search for a way to do it.

[Antonio Linares]

Peter,

Solved:

Code: Select all  Expand view

#define EM_LINESCROLL  0x00B6
...
@ 3, 8.5 BUTTON "&Bottom";
ACTION ( oGet:GoBottom(), oGet:SendMsg( EM_LINESCROLL, 0, oGet:GetLineCount() ), oGet:SetFocus() )


We are going to modify Class TMGet to do it automatically.

Thanks

Will you be modifing the FWH mget class GoBottom() method ?
If so can you let me have the modified method please

Peter,

METHOD GoBottom() INLINE ( ::SetPos( Len( AllTrim( ::GetText() ) ) + 1 ),;
::SendMsg( EM_LINESCROLL, 0, ::GetLineCount() ) )
