Repaint slowness in TBar

[Enrico Maria Giordano]

In the following sample, please try to move another app over the buttonbar. You should see that the buttonbar background become temporarily white as the covering window moves:

Code: Select all  Expand view

#include "Fivewin.ch"


FUNCTION MAIN()

    LOCAL oDlg

    DEFINE DIALOG oDlg;
           SIZE 1000, 600

    ACTIVATE DIALOG oDlg;
             ON INIT TOOLBAR( oDlg );
             CENTER

    RETURN NIL


STATIC FUNCTION TOOLBAR( oDlg )

    LOCAL i

    DEFINE BUTTONBAR OF oDlg 2007

    FOR i = 1 TO 35
        DEFINE BUTTON OF oDlg:oBar;
               FILE "C:\FWH\BITMAPS\OPEN.BMP"
    NEXT

    RETURN NIL

I tried your program with harbour and xHarbour, but I have not encountered the problem you reported.

C Compiler BCC 55
Harbour 3.0
xHarbour 1.2.1
FWH 11.10

Maybe the problem is with a newer FWH version?

Can you try under XP? Remember: you have to quickly move another window (you can start a second instance of the sample) over the buttonbar. Try to move it from right to left, starting with the buttonbar completerly covered.

Enrico,

With Harbour in Windows 7 and in XP shows fine.

With xHarbour.org in XP sometimes I experience a delay and flashing when painting the bar.

What´s the function used in FW to paint the buttons?.

Tnasbmp?.

[Enrico Maria Giordano]

It seems that only I have this problem. Any ideas on what is could be the reason?

Enrico,
do you use WINDOWS standard view or AERO on your PC.
Best regards,

I use XP. I tried to run my sample on a Notebook with Vista (Aero) without problem. What could it be in my PC (XP) that slows the buttonbar repaint?...

I know this may sound a bit in 'left field' .. see if there is an updated video driver for your pc .. it may or may not make any difference.

Thank you. Unfortunately, my video driver is updated.

With xp professional Ihad often these errors in past.

Can you try to use F8 or Provvisor Section xp at init and see if it make error with only Vga system

Or you can erase your driver and make upgrade of your graphic driver

Often there are many app use graphic driver ( DLL) in memory of Pc and leak resources.
