cursorRect function
Cursor rect for shape (0 block, 1 underline, 2 beam, 3 hollow) at cell origin.
Implementation
Rect cursorRect(int shape, double cellWidth, double cellHeight, double lineWidth) {
switch (shape) {
case 2: // beam
return Rect.fromLTWH(0, 0, lineWidth * 2, cellHeight);
case 1: // underline
return Rect.fromLTWH(0, cellHeight - lineWidth * 2, cellWidth, lineWidth * 2);
default: // block (0) and hollow (3) use the full cell
return Rect.fromLTWH(0, 0, cellWidth, cellHeight);
}
}
