Hey guys,

I'm trying to draw fomatted text on the screen, but the text goes out garbled - usually squares, but sometimes other garbage.
The problem is either with TBuf's Format method, or with DrawText getting TBuf.
Anyway, it doesn't happen when I just use the resource directly, as can be seen in the code below.

_LIT(KREPORT, "%s");
_LIT(KRESOURCE, "something");
	
TBuf<10> message;
message.Format(KREPORT, "something");
   
CWindowGc& gc = SystemGc();
gc.Activate(Window());
gc.UseFont(CEikonEnv::Static()->TitleFont());
gc.SetPenColor(KRgbGreen);
    
TPoint p1(10, 20);
gc.DrawText(message, p1);
TPoint p2(10, 60);
gc.DrawText(KRESOURCE, p2);
gc.Deactivate();

The first DrawText garbles the text, while the second one doesn't.

Anyone got an idea why this should happen or how to solve it?

Cheers,
Nate.

Hi,
Why you need this line

message.Format(KREPORT, "something");

This statement not looking correct. what your exact requirements and you can also go through with helloworldplus example.

Hey kkrish,

Thanks for your answer.
I'm trying to save four messages in an array and draw them on the four corners of the screen. They keep being updated, so I need to draw directly from the array and update the array from char *.

class CSomething
{
...
private:
TBuf<10> iMessages[4];   
int ixOffset;
int iyOffset;
TPoint iCorners[4];
}

void CSomething::InitReport()
{
	const TText *t = _S("");
	for (int i=0; i<4; i++)
		iMessages[i] = t;
		
	ixOffset = 10;
	iyOffset = 20;
	
	iCorners[0] = TPoint(ixOffset, iyOffset); 
	iCorners[1] = TPoint(IMAGE_WIDTH-ixOffset, iyOffset); 
	iCorners[2] = TPoint(ixOffset, IMAGE_HEIGHT-iyOffset);
	iCorners[3] = TPoint(IMAGE_WIDTH-ixOffset, IMAGE_HEIGHT-iyOffset); 
}

void CSomething::Report(char *aWhat, TCorner aCorner)
{
	_LIT(KREPORT, "%s");
	
	switch (aCorner)
	{
	case ETL:
		iMessages[0].Format(KREPORT, aWhat);
		break;
	case ETR:
		iMessages[1].Format(KREPORT, aWhat);
		break;		
	case EBL:
		iMessages[2].Format(KREPORT, aWhat);
		break;
	case EBR:
		iMessages[3].Format(KREPORT, aWhat);
		break;
	}
}
	
void CSomething::DrawText(char *aWhat, TCorner aCorner)
{
	CWindowGc& gc = SystemGc();
	gc.Activate(Window());
	gc.UseFont(CEikonEnv::Static()->TitleFont());
	gc.SetPenColor(KRgbGreen);
	
	for (int i=0; i<4; i++)
		gc.DrawText(iMessages[i], iCorners[i]);
	
	gc.Deactivate();
}

If you know why the text is garbled or if you have a better idea of how to do the whole thing please let me know

Cheers,
Nate.
