Row Refresh in a BROWSE

[Red2]

Hi,

In a (simple) BROWSE the ACTION of a right-click calls the following function.

Code: Select all

function Browse_Field_Change( p_lPrint)
	if ( p_lPrint )		// TRUE
		if ( upper( By_State->MergeState ) != "Y" )
			replace By_State->MergeState with "Y"
		endif
	else			// FALSE
		if ( By_State->MergeState != " " )
			replace By_State->MergeState with " "
		endif
	endif
	// Refresh the current BROWSE row!!!
return Nil

The value of field MergeState is correctly changed.
PROBLEM: I have not been able to dynamically make this row's change appear in the BROWSE.

It does not appear in the BROWSE until I
1) exit the form
then
2) Re-open the form

QUESTION:
In HMG/Harbour how can I dynamically refresh the current BROWSE row (whose value(s) have changed)?

Thank you for your kind guidance and suggestions.

Regards,
Red2

I think you can call
brow_data:Refresh(.T.)
for it

Refresh causes refreshing whole BROWSE control and screen flickering

[Anand]

Then maybe
brow_data:Refresh(.f.)

I mixed up.

hi,

Refresh Method
Refresh Content For a Data-Bound Control

Syntax:
<WindowName>.<ControlName>.Refresh

Data-bound Grid supports an optional logical parameter. When set to .t., the selected logical records is preserved.

so when using Parameter .T. it only update Record (refreshCurrent) and not hole Display.

Is it valid for BROWSE control?

[Anand]

Sample c:\MiniGUI\SAMPLES\Advanced\Tsb_Basic\ of Harbour MiniGUI Extended Edition uses
oBrw:Refresh(.T., .T.)
so it is valid.

But do not know about HMG 3.4.4

Tsbrowse is absent in HMG

[Red2]

Thank you so much for your very kind help and the suggestion: brow_data:Refresh(.f.).
(Note: My BROWSE is a simple Browse, not a TBrowse or a GRID).

Unfortunately I remain UNsuccessful.

My BROWSE is defined (named) as "BrowseStates" so I tried the following syntax. Question: Is my syntax/implementation wrong?

Code: Select all

BrowseStates:Refresh(.F.) // This generates the error "Error BASE/1003  Variable does not exist:  BROWSESTATES".  

I notice that the sample PRGs in Harbour MiniGUI Extended Edition, c:\MiniGUI\SAMPLES\Advanced\Tsb_Basic\Demo.PRG, include the line

Code: Select all

#include "TSBrowse.ch"

In HMG can a simple BROWSE actually be refreshed?????

Finally
The HMG .CHM help file shows a "Refresh Method", <WindowName>.<ControlName>.Refresh. It is described as "Refresh Content For a Data-Bound Control". My form/window is (named) "DataBrowse". However

Code: Select all

DataBrowse.BrowseStates.Refresh(.T.) // Generates error "Error BASE/1003  Variable does not exist: DATABROWSE"

Can anyone suggest, in HMG, a way to code a REFRESH in a "normal" BROWSE? I would be very much appreciate your your expert advice.

Thanks again!

Please try this

Code: Select all

DoMethod("DataBrowse","BrowseStates","Refresh")

But as Marek wrote screen flickering.
