XBROWSE Column Question

[nageswaragunupudi]

how is the Syntax to use "Header - click" to SET Order / TAG

Set

Code: Select all  Expand view

oBrw:lAutoSort := .t.  // default .f.

to invoke autosort feature.
We can also use AUTOSORT clause in the XBROWSE command, which sets the flag.
When autosort flag is ON, XBrowse automatically sorts the data on click of header, using the value in oCol:cSortOrder.
First click on the header sorts the data in ascending order.
Second click on the header sorts the data in descending order. In case of DBF, it uses the RDD function OrdDescend()

If oCol:cSortOrder is empty XBrowse does not attempt to sort.
Note: FWH2304 provides a way to sort such columns too. We discuss it in another topic.

when usig OrdWildSeek() in XBROWSE how to "continue"
i did not found a 2nd OrdWildSeek() or a loop

No need for 2nd call or loop.

Code: Select all  Expand view

OrdWildSeek(oBrw:cSeek, oBrw:lSeekNext )

works for first seek and SeekNext automatically.

Note:Syntax

Code: Select all  Expand view

OrdWildSeek( cSeek, [lFromNextRec], [lBakwards]) --> lFound

Inspired by your postings, we introduced automatic SeekNext by pressing F3 key from FWH2304.
As of now, this works for arrays, DBF, TDatabase, all ADO rdbms, FW MySql. Yet to implement for dolphin,tmysql,eagle1,postgre, etc.

Here is a sample for ordwildseek. It's new to me....

Mr. Venken
OrdWildSeek( cSeek, ... ) is actually an (x)Harbour function in DBFNTX and DBFCDX RDDs, applicable for indexed DBFs.
We can seek expressions like "*A?C"

The above post refers to similar functionality we created in FWMaria library for MySql tables.
In fact, there was not problem that was solved in the post. He was not aware that we already implemented and we just clarified that it was implemented and working ok

hi,

WOW, that is nice

When autosort flag is ON, XBrowse automatically sorts the data on click of header, using the value in oCol:cSortOrder.
First click on the header sorts the data in ascending order.
Second click on the header sorts the data in descending order. In case of DBF, it uses the RDD function OrdDescend()

ah, i did not know OrdDescend() as Xbase++ does not have it

but how can it continue without press a Key

Yes, that would be fine, thx

[nageswaragunupudi]

but how can it continue without press a Key

SeekNext is performed when F3 key is pressed by the user.

hi,

but how can it continue without press a Key

SeekNext is performed when F3 key is pressed by the user.

this is for "new" Version or include in older Version 2022/07 also

i do have a Buttonbar where i have F3
will it "override" F3 "internal"

[nageswaragunupudi]

SeekNext is implemented in FWH2304 which is triggered by F3.
It is not there in previous versions.

This is triggered when oBrw window receives WM_KEYDOWN message with F3 key.
(i.e., it is implemented in oBrw:KeyDown() method)
