xBrowse: Vertical Merge

[hua]

Hi,
Trying to set up vertical merge on Col 1 and Col 2. But doesn't seem to work.
Am using Harbour+FWH1912 for this.

What seems to be wrong:
1. Despite merging, horizontol lines are still painted in col 1
2. Only one checkbox appeared in col 2. Col 2 should have 2 check boxes. One for item 1 the other for item 2

Any help is appreciated TIA

Code: Select all  Expand view

  redefine xbrowse ::oBrw id 101 of ::oDlg ;
     columns LN_CARGO, LN_SELECT, LN_REMA, LN_ACCN, LN_ACCNDESC, LN_AMOU                ;
     headers "No", "", "Remarks", "Code", "Account", "Amount (" + TRIM( zCurr ) + ") " ;
     lines ;
     array ::aFiledbf ;
     update

    ::oBrw:nStretchCol         := STRETCHCOL_WIDEST
    ::oBrw:bKeyDown            := { | nKey | ::FC_ONCHG( nKey )   }
    ::oBrw:bClrSel             := {|| {CLR_BLACK, CLR_HGRAY} }
    ::oBrw:bClrStd             := {|| {CLR_BLACK, bckClr(::oBrw)} }

    aeval(::oBrw:aCols,{|o| o:bLDClickData  := { || ::FC_ONCHG( VK_RETURN) }, o:nEditType := EDIT_GET})
    ::oBrw:aCols[2]:setCheck()
    ::oBrw:No:lMergeVert := .t.
    ::oBrw:aCols[2]:lMergeVert := .t.

Here's a reduced, self-contained sample.

1. recur.rc

Code: Select all  Expand view

STYLE DS_ABSALIGN | DS_MODALFRAME | WS_POPUP | WS_VISIBLE | WS_CAPTION
CAPTION "Insert Recurring Items"
FONT 10, "System"
{
 CONTROL "&Ok", 102, "BUTTON", BS_PUSHBUTTON | WS_CHILD | WS_VISIBLE | WS_TABSTOP, 165, 283, 50, 16
 CONTROL "", 101, "TXBrowse", WS_CHILD | WS_VISIBLE | WS_VSCROLL | WS_HSCROLL | WS_TABSTOP, 5, 21, 431, 251
}

Hi Rao,
Could you offer some insight? TIA

[nageswaragunupudi]

In the present implementation, we see the horizontal lines if the back color of bClrStd is not the same as oBrw:nClrPane (by default CLR_WHITE).
So, if you choose CLR_WHITE as the back color in bClrStd, you will not see these lines.

We improved this in the version FWH2004 to be released soon. With this improvement, your example will look fine.

[nageswaragunupudi]

This is how your program will look like from FWH2004 onwards.

Thank you for solving the line issue Rao. Great work!

Can you advice me on the 2nd column? It is also merged. I expected to see 3 check boxes. One for each No but only one is shown.

The checkbox will be toggled when user double click on any of the row to indicate which sets are selected by user

TIA

After the line

Code: Select all  Expand view

   oBrw:aCols[2]:lMergeVert := .t.
 

Add this line of code:

Code: Select all  Expand view

  oBrw:aCols[2]:bMergeValue := { |oCol| oCol:oBrw:aRow[ 1 ] }

Hi Rao,

Add this line of code:

Code: Select all  Expand view

  oBrw:aCols[2]:bMergeValue := { |oCol| oCol:oBrw:aRow[ 1 ] }
 

The above works in my reduced self-contained sample but in my actual program it causes the checkbox to appear on each row of items.
Both were linked with FWH1912.

1. Any idea on what can I do to start finding why the different behaviour?
2. Can you share what need to be changed in xbrowse source to eliminate the white lines?

TIA

[nageswaragunupudi]

1) Please try

Code: Select all  Expand view

oBrw:aCols[2]:bMergeValue := { |oCol| oCol:oBrw:aCols[ 1 ]:Value }
 

2) Please keep back color in all bClrStd as CLR_WHITE and see.

[hua]

Thanks for the prompt reply Rao!

All your suggestions works. Thanks!

Hi Rao,
Can I have zebra effect by playing with fonts for each set of No.?

If it's possible can you share the snippet to do it?

TIA

[nageswaragunupudi]

Please try:

Code: Select all  Expand view

oBrw:oDataFonts := { || If( <cond>, oFont1, oFont2 ) }

[hua]

Please try:

Code: Select all  Expand view

oBrw:oDataFonts := { || If( <cond>, oFont1, oFont2 ) }

Thanks Rao! It works!
