DrawText with variables

[Sufo]

Wondering if there is a way, or rather, what the best way is to draw text with variables. The DrawText() function from CGraphicsContext doesn't seem to to allow for specifiers like printf for example. Let's say i wanted to have a variable where the specifier is in the code below, would i have to draw it next to it, using a different function?

_LIT(KExampleText,"Number: %d\n");
iBmpGc->DrawText(KExampleText,pos);

cheers

i suggest using a buffer to prepare the text to be displayed 1st.

Hi,

TInt value = 3;
TBuf<32> buf; // it is not good to use a magic number here
buf.Format(KExampleText, value); // "Number: 3\n"
iBmpGc->DrawText(KExampleText, pos);

Try this code:

TBuf<32> buf;
for (i=0;i<7;i++) {
box = TRect(32,i*32,64,(i+1)*32);
gc.DrawRoundRect(box,TSize(8,8));
buf.Format(_L("%i"),i+1);
gc.DrawText(buf,box,24,CGraphicsContext::ECenter,0);
}

It works fine!
