TWBrowse scrollbar bug

[Enrico Maria Giordano]

In the following sample, try to hit down arrow key (on the keyboard) many times till to move the highlight to the last record and then hit down arrow key one more time. Now hit up arrow key and you will see that the scrollbar thumb doesn't move up (it will move when you hit up arrow key again):

Code: Select all

#include "Fivewin.ch"


REQUEST DBFCDX


FUNCTION MAIN()

    LOCAL oDlg, oBrw

    RDDSETDEFAULT( "DBFCDX" )

    USE TEST

    INDEX ON FIELD -> last + FIELD -> first TO "TEMP__" FOR FIELD -> last = "A"

    DEFINE DIALOG oDlg;
           SIZE 400, 400

    @ 1, 1 LISTBOX oBrw FIELDS TEST -> last,;
                               TEST -> first;
           SIZE 200, 200 PIXEL

    oBrw:bLogicLen = { || ( oBrw:cAlias ) -> ( OrdKeyCount() ) }

    ACTIVATE DIALOG oDlg;
             CENTER

    CLOSE

    FERASE( "TEMP__.CDX" )

    RETURN NIL

A possible fix:

Code: Select all

METHOD VGoDown()       INLINE iif( ::nVScrollPos < ::nLen, ::VSetPos( ::nVScrollPos + 1 ), )
METHOD VGoUp()         INLINE iif( ::nVScrollPos > 1, ::VSetPos( ::nVScrollPos - 1 ), )

Are you aware that this also happens when you do the same at the top of the browse i.e. go to the top and do the same thing with the arrow key (or click on the scroll bar up arrow) and the same thing happens?

Regards,

Dale.

[Enrico Maria Giordano]

Yes. That's why I fixed both methods VGoDown() and VGoUp().

Sorry, I did not see that.

But you have no idea how grateful I am!!!

Now what about being able to make the lines and headings higher / wider AND GETTING IT INCORPORATED INTO THE NEXT RELEASE OF FWH?

And let us not forget about the WIN32 HEADERS!!!

Thanks,

Dale.

[dpaterso]

I can't thank you enough!!!

In wbrowse.prg there is a single call to DrawHeader() function. Try to play with it.

Enrico hi,
Any idea how I can add lines (horizontal separator lines, as in TWBROWSE() from record to record when browseing a single dimensional array ?

Have you tried oBrw:nLineStyle?

nLineStyle is an instance variable of TWBrowse not of TListBox.

Correct.
I am using TLISTBOX, and asked if I can make a listbox have horizontal line separators between items, as we have it in TWBROWSE...
I didn't find any method in TLISTBOX to guide me towards this problem, and therefore I ask for your opinion and a piece of your knowledge.

[Enrico Maria Giordano]

No, you can't, as far as I know.
