Hi,
I asked this once before and someone from sun said he or she would look
into it. I'd like to know if anyone knows how to fix it, or a workaround
as it is causing some problems. Couldn't find it in the Bug database
either.
I'm trying to draw Strings (see code snippet below) and every now and
then I get the following Exception.
java.lang.IllegalArgumentException: Font

Method)

If someone could tell me what was going on in the native code
sun.awt.font.NativeFontWraper... maybe I could work around it by
fiddling with the font or something. The drawing code:
public void drawString(String string, Color stringColor) {
Shape shape = g2.getClip();
g2.setClip(curX, curY, curWidth, curHeight);
drawInit(stringColor);
FontRenderContext rContext = g2.getFontRenderContext();
Rectangle2D bounds = currentFont.getStringBounds(string, rContext);
int xCenter = curX + curWidth / 2;
int yCenter = curY + curHeight / 2;
int strX = xCenter - (int)bounds.getCenterX();
int strY = yCenter - (int)bounds.getCenterY();
g2.drawString(string, strX, strY); <= Exception
thrown here
g2.setClip(shape);
}
This could hold up the release of some simulation software we are
developing here, so any suggestions would be appreciated.
thanks,
Nick
