DrawNow() don't involve Draw()

[agan1003]

I have a problem now.
In S60 3rd fp2,DrawNow() don't involve Draw(),but it can in the S60 3rd mr.

This is my draw() function.
void CMyCoeControl:raw(const TRect& aRect) const
{
CWindowGc& gc = SystemGc();
gc.Clear();

gc.SetBrushStyle(CGraphicsContext::ENullBrush);
gc.SetPenStyle(CGraphicsContext::ESolidPen);
gc.SetPenColor(KRgbBlue);

gc.UseFont(iFont);
gc.DrawText(iText, aRect, iFont->HeightInPixels(), CGraphicsContext::ECenter);
gc.DiscardFont();
}
Thank you!

Hello,
it s rather not possible that it happens.

How do you have defined your iFont
Are you sure that you put text to iText before you call DrawNow ?

good luck

Hi,

DrawNow() internally calls your Draw() api and it issue a request to the windows server which checks the validity of your window etc etc and then calls Draw() api it is not a synchrous call.

also make sure you do not block the control flow.

I set the draw() to null,it can't be involved by drawnow()!
