示例1: GetHitTestInfo
public override HitTestInfo GetHitTestInfo(IGraphics gr, int x, int y, Point pt)
{
// caller will have tested if point is within bounding rect
// taking into account additional ascent/descent on the line
Debug.Assert(style != null, "No class attached to TextFragment!!");
string text=ProcessText(Text);
gr.PushFont(gr.GetFontHandle(style.FontDesc));
try
{
BinaryChopper bc=new BinaryChopper(text);
int w=0;
while ( bc.CanMove )
{
// TODO: L: this could be optimised by calculating the shift
// left and right in pixels rather than measuring from zero
w=gr.MeasureText(bc.Text).Width;
if ( pt.X < x+w )
bc.TooLong();
else
bc.TooShort();
}
int cw=gr.MeasureText(text[bc.Position].ToString()).Width;
bool after=(float) 1.0 * x + w - cw / 2 < pt.X;
Debug.Assert(start+bc.Position < Node.Value.Length, "Invalid TextSelectionPoint!");
SelectionPoint sp=new TextSelectionPoint(Node, start+bc.Position);
Line l=(Line) Parent;
LineItemContext ili=new LineItemContext(l.Height, l.Baseline, this, new Point(x,y));
HitTestInfo ht=new HitTestInfo(sp, ili, after);
return ht;
}

{
gr.PopFont();
}
}示例2: Bind
public void Bind(IGraphics gr, Stylesheet s)
{
stylesheet=s;
FontDesc fd=desc;
if ( fd.Family == null )
fd=s.DefaultFont;
object fontHandle=gr.GetFontHandle(fd);
gr.PushFont(fontHandle);
fontAscent=gr.GetFontAscent();
fontHeight=gr.GetFontHeight();
gr.PopFont();
}示例3: GetCaretPosition
public override void GetCaretPosition(IGraphics gr, int x, int y, SelectionPoint sp, ref CaretPositionInfo cpi)
{
// TODO: M: this is very innefficient since it is called for all text nodes during search
if ( !ContainsSelectionPoint(sp) )
{
cpi.UpdateLocation(x+Width, y, Height, CaretSetting.Fallback);
return;
}
TextSelectionPoint tsp=(TextSelectionPoint) sp;
CaretSetting mode=CaretSetting.Absolute;
gr.PushFont(gr.GetFontHandle(style.FontDesc));
try
{
int n=tsp.Index-start;
if ( n < 0 )
{
// position is not in visible part of the string, it's
// in whitespace that has been trimmed.
cpi.UseSecondary=true;
return;
} else if ( tsp.Index == 0 )
{
// caret can be put somewhere else if necessary
// TODO: L: this is a bit simplistic - will be wrong if text nodes are
// split and first node ends with space and ends a line (!)
mode=CaretSetting.Accurate;
}
string text=Text;
if ( n > text.Length )
// TODO: L: not sure exactly when this happens
n=text.Length;
text=ProcessText(text.Substring(0, n));
int w=gr.MeasureText(text).Width;
cpi.UpdateLocation(x+w, y, Height, mode);
}
finally
{
gr.PopFont();
}
}示例4: Recurse
private static void Recurse(int depth, IGraphics gr, Rectangle rc)
{
object o;
FontDesc fd;
fd=new FontDesc("Arial", 10, false, false, false);
o=gr.GetFontHandle(fd);
gr.PushFont(o);
gr.MeasureText("my name is alfie");
gr.DrawText(rc, 20, "hello", Color.Black, Color.White, -1, -1);
fd=new FontDesc("Times New Roman", 10, false, false, false);
o=gr.GetFontHandle(fd);
gr.PushFont(o);
gr.MeasureText("my name is alfie");
fd=new FontDesc("Arial", 10, false, false, false);
o=gr.GetFontHandle(fd);
gr.PushFont(o);
gr.MeasureText("my name is alfie");
if ( depth < 100 )
Recurse(depth+1, gr, rc);
gr.PopFont();
gr.PopFont();
