Question

I have a multiline text string (e.g. ‘Stuff\nMore Stuff\nYet More Stuff’), and I want to paint it, along with a bitmap into a tooltip. Since I am painting the bitmap, I need to set OwnerDraw to true, which I am doing. I am also handling the Popup event, so I can size the tooltip to be large enough to hold the text and the bitmap.

I am calling e.DrawBackground and e.DrawBorder(), and then painting my bitmap on the left side of the tooltip area.

Is there a set of flags I can pass to e.DrawText() in order to left-align the text, but to offset it so that it doesn’t get painted over my bitmap? Or do I need to custom draw all the text as well (which will probably involve splitting the string on newlines, etc)?

UPDATED: The final code looks like this:

private void _ItemTip_Draw(object sender, DrawToolTipEventArgs e) {   e.DrawBackground();   e.DrawBorder();    // Reserve a square of size e.Bounds.Height x e.Bounds.Height   // for the image. Keep a margin around it so that it looks good.   int margin = 2;   Image i = _ItemTip.Tag as Image;     if (i != null)   {     int side = e.Bounds.Height - 2 * margin;       e.Graphics.DrawImage(i, new Rectangle(margin, margin, side, side));   }    // Construct bounding rectangle for text (don't want to paint it over the image).   int textOffset = e.Bounds.Height + 2 * margin;    RectangleF rText = e.Bounds;   rText.Offset(textOffset, 0);   rText.Width -= textOffset;    e.Graphics.DrawString(e.ToolTipText, e.Font, Brushes.Black, rText); } 

Answer 1

I assume that if you define the bounding rectangle to draw in (calculating the image offset yourself) you could just:

     RectangleF rect = new RectangleF(100,100,100,100);      e.Graphics.DrawString(myString, myFont, myBrush, rect);
