示例1: _prepareRender

	private _prepareRender(ctx: IRenderingContext): ViewCursorRenderData {
		if (this._cursorStyle === TextEditorCursorStyle.Line || this._cursorStyle === TextEditorCursorStyle.LineThin) {
			let visibleRange = ctx.visibleRangeForPosition(this._position);
			if (!visibleRange) {
				// Outside viewport
				return null;
			}
			let width: number;
			if (this._cursorStyle === TextEditorCursorStyle.Line) {
				width = this._isSecondary ? 1 : 2;
			} else {
				width = 1;
			}
			return new ViewCursorRenderData(visibleRange.top, visibleRange.left, width, '');
		}

		let visibleRangeForCharacter = ctx.linesVisibleRangesForRange(new Range(this._position.lineNumber, this._position.column, this._position.lineNumber, this._position.column + 1), false);

		if (!visibleRangeForCharacter || visibleRangeForCharacter.length === 0 || visibleRangeForCharacter[0].ranges.length === 0) {
			// Outside viewport
			return null;
		}

		let range = visibleRangeForCharacter[0].ranges[0];
		let top = ctx.getViewportVerticalOffsetForLineNumber(this._position.lineNumber);
		let width = range.width < 1 ? this._typicalHalfwidthCharacterWidth : range.width;

		let textContent = '';
		if (this._cursorStyle === TextEditorCursorStyle.Block) {
			let lineContent = this._context.model.getLineContent(this._position.lineNumber);
			textContent = lineContent.charAt(this._position.column - 1);
		}

		return new ViewCursorRenderData(top, range.left, width, textContent);
