Listbox color for a single column

[Rick Lipkin]

To All

I am using the standard TWBrowse ( listbox ) and I want to be able to turn a cell in a row ( column status ) a certain color .. crudely like this

col1 col2 col3 status

xxx xxx xxx RED
xxx xxx xxx GREEN
xxx xxx xxx YELLOW

I can turn the entire row a particular color based on the data in the "status" column .. but turning the entire row a particular color gets too busy... just want to turn the "status" cell in each row a certain color based on the data in that cell.

Any Ideas ??

Thanks

Try using nClrPane property:

Code: Select all  Expand view

oBrw:nClrPane = { | nCol | If( nCol = 1, CLR_HRED, CLR_HGREEN ) }

Sorry for the late post .. first chance I have had to get back to this color column issue .. I looked at the samples brwcolor.prg .. however it does not use table fields and it is hard to interpret the array values ..

Here is my code .. I want to look at the last defined column and test for the value of "row_color" = "GREEN" to turn that column green.

The sample code turns the entire row green .. not just the last column .. using standard Twbrowse FWH class ..

Hi Rick:

I'm afraid that standard TWBrowse is not a column based browser, then you can't define column or cell colors. That is possible only with TCBrowse or TXBrowse talking about standard FWH browsers.

This is not true. From FWH May 2008 whatsnew.txt:

* Enhancement: Class TWBrowse DATA nClrPane if used as a codeblock, now receives a numeric
parameter with the column to be displayed, so you can change the color of a single cell.
Please review samples\BrwColor.prg.

It is a bug that I already reported here:

What was the fix ?? something I can modify on my end ??

Rick,

The fix is explained here:

Yes, you can easily implement it.

I made the change in Wbrowse and included it to my compile list .. I had to modify the code block .. here was the fix:

oLbx:nClrPane = { | nCOL | if( (nCOL = 8 .and. oRsRpt:Fields("row_color"):Value = "GREEN"), CLR_GREEN, CLR_WHITE ) }

Thanks

Rick,

Yes, you can implement the codeblock the way you need it

You might want to look a nClrText as well .. I have not had a chance to track it down and look in Wbrowse .. I wanted clr_white text on a clr_green background ..

nClrText seems to exibit the same row behavoir and does not seem to respect the cell designation.

Rick,

Fixed, the same n was missing in Eval( nClrTxt, n )

Thanks!
