Problem with DrawText()

[gowthamgowtham]

Hi, I am trying to create a custom control (COnTopText) which stays always on top of the screen and carries some text in it.

I am trying to draw the text using CWindowGc:rawText(), but for some reason I am not able to get it work.



Here is my code:

void COnTopText::ConstructL()
{
	iMyWinowGroup = RWindowGroup( iCoeEnv->WsSession());
	User::LeaveIfError( iMyWinowGroup.Construct( (TUint32) &iMyWinowGroup) );
	
	iMyWinowGroup.SetOrdinalPosition( 0, ECoeWinPriorityAlwaysAtFront );
	iMyWinowGroup.EnableReceiptOfFocus( EFalse );
	
	CreateWindowL( &iMyWinowGroup );
	SetRect(TRect(5,250,235,279));
	ActivateL();	
	DrawNow();	
}

void COnTopText::Draw( TRect &aRect ) const
{
	CWindowGc &gc = SystemGc();
	
	gc.Clear();
	gc.UseFont( iCoeEnv->NormalFont());
	gc.SetPenColor( TRgb( 0, 0, 0xFF ));
	gc.DrawText( KMyText, TPoint( 7, 252 ) );
}

Please help...

Watch out the coordinates. Note that when drawing, it is relative to the control, not the window.

I tried with each and every combination of the co-ordinates possible, but still could not see any text written.

Am I missing something else (perhaps with gc?)

void COnTopText::Draw( TRect &aRect ) const
{
	CWindowGc &gc = SystemGc();
	
	gc.Clear();
	gc.UseFont( iCoeEnv->NormalFont());
	gc.SetPenColor( TRgb( 0, 0, 0xFF ));
	TInt x, y;
	// This code assumes relavtive co-ordinates
	for( x = 1; x < ( 235 - 5 ); x++ )
	{
		for( y = 1; y < ( 279 - 250 ); y++ )
		{
			gc.DrawText( KMyText, TPoint( x, y ) );
		}
	}
	// This might work if absolute co-cordinates are needed by DrawText()
	for( x = 6; x < 235; x++ )
	{
		for( y = 251; y < 279; y++ )
		{
			gc.DrawText( KMyText, TPoint( x, y ) );
		}
	}
}

Note that your method never gets invoked (BTW: why do not you use a debugger??), const matters in the method signature, there should be two occurences.
