Description

SetAlpha() is used to set the transparency factor. However, the color's alpha information is not drawn when it is used with SetPenStyle() with ENullPen in the Nokia N93.

How to reproduce

The following code snippet can be used to reproduce this

TRgb col2 = KRgbYellow;
col2.SetAlpha(75);   
gc.SetBrushColor(col2);
gc.SetPenStyle(CGraphicsContext::ENullPen);
gc.SetBrushStyle(CGraphicsContext::ESolidBrush);
gc.DrawRect(rect);

Solution

The code below could solve this problem.

gc.SetPenStyle(CGraphicsContext::ESolidPen);
