TWBrowse flickering on dialog

TWBrowse flickering on dialog

Postby Enrico Maria Giordano » Tue Nov 21, 2006 11:12 am

This is the sample (try to resize the dialog):

Code: Select all  Expand view
#include "Fivewin.ch"


FUNCTION MAIN()

    LOCAL oDlg, oBrw

    USE TEST

    DEFINE DIALOG oDlg

    oDlg:nStyle = NOR( oDlg:nStyle, WS_THICKFRAME )

    @ 0, 0 LISTBOX oBrw FIELDS

    ACTIVATE DIALOG oDlg;
             ON INIT oDlg:SetControl( oBrw );
             CENTER

    CLOSE

    RETURN NIL


How can I get rid of the flickering?

Enrico,

dialogboxes don't use buffer painting (Methods DispBegin() and DispEnd()) because it may slowdown the overall performance as there are many controls that get also repainted, thats why you see the flickering.

Can I activate double buffer painting on a specific dialog? How?
