示例1: CalcCaretRectangle
Rect CalcCaretRectangle(VisualLine visualLine)
{
if (!visualColumnValid) {
RevalidateVisualColumn(visualLine);
}
TextLine textLine = visualLine.GetTextLine(position.VisualColumn);
double xPos = visualLine.GetTextLineVisualXPosition(textLine, position.VisualColumn);
double lineTop = visualLine.GetTextLineVisualYPosition(textLine, VisualYPosition.TextTop);
double lineBottom = visualLine.GetTextLineVisualYPosition(textLine, VisualYPosition.LineBottom);
return new Rect(xPos,
lineTop,
SystemParameters.CaretWidth,
lineBottom - lineTop);
}示例2: CalcCaretOverstrikeRectangle
Rect CalcCaretOverstrikeRectangle(VisualLine visualLine)
{
if (!visualColumnValid) {
RevalidateVisualColumn(visualLine);
}
int currentPos = position.VisualColumn;
// The text being overwritten in overstrike mode is everything up to the next normal caret stop
int nextPos = visualLine.GetNextCaretPosition(currentPos, LogicalDirection.Forward, CaretPositioningMode.Normal, true);
TextLine textLine = visualLine.GetTextLine(currentPos);
Rect r;
if (currentPos < visualLine.VisualLength) {
// If the caret is within the text, use GetTextBounds() for the text being overwritten.
// This is necessary to ensure the rectangle is calculated correctly in bidirectional text.
var textBounds = textLine.GetTextBounds(currentPos, nextPos - currentPos)[0];
r = textBounds.Rectangle;
r.Y += visualLine.GetTextLineVisualYPosition(textLine, VisualYPosition.LineTop);
} else {
// If the caret is at the end of the line (or in virtual space),
// use the visual X position of currentPos and nextPos (one or more of which will be in virtual space)
double xPos = visualLine.GetTextLineVisualXPosition(textLine, currentPos);
double xPos2 = visualLine.GetTextLineVisualXPosition(textLine, nextPos);
double lineTop = visualLine.GetTextLineVisualYPosition(textLine, VisualYPosition.TextTop);
double lineBottom = visualLine.GetTextLineVisualYPosition(textLine, VisualYPosition.TextBottom);
r = new Rect(xPos, lineTop, xPos2 - xPos, lineBottom - lineTop);
}
// If the caret is too small (e.g. in front of zero-width character), ensure it's still visible
if (r.Width < SystemParameters.CaretWidth)
r.Width = SystemParameters.CaretWidth;
return r;
