XBrowse: Using Get for incremental Seek/Filters

[Silvio.Falconi]

As the name suggests, oBrw:cFilterFld is to be assigned with a Field Name, not cHeader of a column.
When the user selects a column in the combobox, you need to find of the name of the field used for that column and assign that name to oBrw:cFilterFld.

Rao,
U're right

but

on sample test (xbincflt.prg) I assign the field name on oBrw:cFilterFld with oBrw:cFilterFld:=aFlds[::nat], what is wrong ?

Code: Select all | Expand

 @ 10, 10 COMBOBOX oBrw:cFilterFld ;      ITEMS aHdrs ;      ON CHANGE (   CUST->(OrdSetFocus(::nat)),;                     oBrw:refresh(),;                     oBrw:cFilterFld:=aFlds[::nat],;                     Msginfo(oBrw:cFilterFld, aFlds[::nat]),;                     oBrw:Seek( "" ),;                     oBrw:SetFocus() ) ;      SIZE 50,400 PIXEL OF oDlg

I insert a Msginfo to check if the oBrw:cFilterFld is changed


on your sample test modified, adding the combobox, I made the same

when I change on combobocx give me a msginfo to check if the field is changed

Msginfo(oBrw:cFilterFld, aColumns[nField])

So, the oBrw:cFilterFld is changed but the xbrowse search allways the name of the Header

[Silvio.Falconi]

Nages,
trying this evening I saw on 7471 (xbrowse)

I insert the same text on xbrowse as the fields

@ 30,10 XBROWSE oBrw SIZE -10,-10 PIXEL OF oDlg ;
COLUMNS aFlds HEADERS aFlds ;
DATASOURCE uDataSource AUTOSORT CELL LINES NOBORDER


but the search take the name of the Items of combobox

[Silvio.Falconi]

Antonio, Nages

@ 20, 280 COMBOBOX oCbx var oBrw:cFilterFld ;
ITEMS aHdrs SIZE 150,400 PIXEL OF oDlg ;
ON CHANGE ( oBrw:cFilterFld := "LAST",;
oBrw:Seek( "" ),;
oBrw:SetFocus() )


it's possible combobox not execute bchange codeblock ?
because I force oBrw:cFilterFld := "LAST" and it not is changed

Hello,

This is not working:

   @ 10,10 SAY oBrw:oSeek PROMPT oBrw:cSeek SIZE 200,10 PIXEL ;      OF oDlg COLOR CLR_BLACK,CLR_YELLOW  PICTURE '@!'       oBrw:oSeek:bValid := { || oBrw:Seek( Trim( oBrw:cSeek ) ) }

Thank you

[elvira]

I need, can be in say or in get, that the user enters all the string, press enter and the filter is processed.

Please, how is it done?

Thank you very much.

[elvira]

Thank you, it is almost working.

But when I press delete key, the filter is changed and the get not updated.

I please need to either that the delete key does nothing, or it deletes the content of the get field.

This is a sample:

Are you using FWH2012? If not, what version of FWH are you using?

Can I see a sample as xbincflt.prg (with combobox and get) with the name of columns different by fields name?
I need to use a dbf anf change text of columns
I need have the system as xbincflt.prg with get and combobox controls
@ 10, 10 COMBOBOX oBrw:cFilterFld ITEMS aHdrs // columns
@ 10, 70 COMBOBOX nWild ITEMS { "Starting With", "Containing" } //
@ 11,160 GET oGet VAR cSeek SIZE 200,14 PIXEL OF oDlg //new feature

thanks

Wonderful
and then If a user hides a column ?, the combobox does not update creating problems

[nageswaragunupudi]

You have to reset the items of the combobox on the basis of columns where oCol:lHide == .f.
