示例1: _layoutBoxInViewport
private _layoutBoxInViewport(position: Position, domNode: HTMLElement, ctx: IRenderingContext): IBoxLayoutResult {
let visibleRange = ctx.visibleRangeForPosition(position);
if (!visibleRange) {
return null;
}
let width = domNode.clientWidth;
let height = domNode.clientHeight;
// Our visible box is split horizontally by the current line => 2 boxes
// a) the box above the line
let aboveLineTop = visibleRange.top;
let heightAboveLine = aboveLineTop;
// b) the box under the line
let underLineTop = visibleRange.top + this._lineHeight;
let heightUnderLine = ctx.viewportHeight - underLineTop;
let aboveTop = aboveLineTop - height;
let fitsAbove = (heightAboveLine >= height);
let belowTop = underLineTop;
let fitsBelow = (heightUnderLine >= height);
// And its left
let actualLeft = visibleRange.left;
if (actualLeft + width > ctx.viewportLeft + ctx.viewportWidth) {
actualLeft = ctx.viewportLeft + ctx.viewportWidth - width;
}
if (actualLeft < ctx.viewportLeft) {
actualLeft = ctx.viewportLeft;
}
return {
aboveTop: aboveTop,
fitsAbove: fitsAbove,
belowTop: belowTop,
fitsBelow: fitsBelow,
left: actualLeft
};
