祝福名单失败
我正在试图做一个简单的列表框。
var blessed = require("blessed"); // Create a screen object. var screen = blessed.screen(); // Create a box perfectly centered horizontally and vertically. var serverList = blessed.list({ align: "center", mouse: true, width: "50%", height: "50%", top: "center", left: "center", items: [ "one", "two", "three", "four", "five", "six", "seven", "eight", "nine", "ten" ] }); // Append our box to the screen. screen.append(serverList); serverList.select(0); // Quit on Escape, q, or Control-C. screen.key(["escape", "q", "Cc"], function(ch, key) { return process.exit(0); }); // Focus our element. serverList.focus(); // Render the screen. screen.render(); 根据文档和chjj/blessed/test/widget.js应该是我所需要的。 但它只是错误地说，它不能读取高。 这是错误。
TypeError: Cannot read property 'height' of null at ScrollableBox.Element._getTop (/home/giodamelio/Projects/real/Vindinium-Bots/node_modules/blessed/lib/widget.js:2595:17) at ScrollableBox.Element._getBottom.parent [as top] (/home/giodamelio/Projects/real/Vindinium-Bots/node_modules/blessed/lib/widget.js:2617:15) at Box.Element._getTop (/home/giodamelio/Projects/real/Vindinium-Bots/node_modules/blessed/lib/widget.js:2613:17) at Box.Element._getBottom.parent [as top] (/home/giodamelio/Projects/real/Vindinium-Bots/node_modules/blessed/lib/widget.js:2617:15) at Screen._focus (/home/giodamelio/Projects/real/Vindinium-Bots/node_modules/blessed/lib/widget.js:1439:19) at Screen.focusPush (/home/giodamelio/Projects/real/Vindinium-Bots/node_modules/blessed/lib/widget.js:1389:8) at Screen.clearRegion [as focused] (/home/giodamelio/Projects/real/Vindinium-Bots/node_modules/blessed/lib/widget.js:1467:15) at ScrollableBox.Node.insert (/home/giodamelio/Projects/real/Vindinium-Bots/node_modules/blessed/lib/widget.js:86:25) at ScrollableBox.Node.append (/home/giodamelio/Projects/real/Vindinium-Bots/node_modules/blessed/lib/widget.js:95:8) at ScrollableBox.List.add.List.addItem.List.appendItem (/home/giodamelio/Projects/real/Vindinium-Bots/node_modules/blessed/lib/widget.js:4262:8)
它看起来像一个blessed的错误。 如果在blessed.list()选项中手动指定了parent: screen ，它将会起作用。 出于某种原因，它不是自动确定父母。
您链接到作品的testing的原因是因为还有其他小部件首先添加到屏幕上，这意味着该列表肯定会有parent设置（以前添加的小部件）。
