I'm using a Canvas to create a Drawable with some background and some text. The drawable is used as a compound drawable inside an EditText. The text is drawn via drawText() on the canvas, but I do have an issue with the y-position of the drawn text in some cases. In those cases parts of some characters are cut off (see image links). Characters without positioning issue: http://i50.tinypic.com/zkpu1l.jpg Characters with positioning issue, text contains 'g', 'j', 'q', etc.: http://i45.tinypic.com/vrqxja.jpg You can find a code snippet to reproduce the issue below. Does any expert know how to

jQuery UI dialog positioning : adjust position top by 20px -

由 独自空忆成欢 提交于 2019-12-03 04:24:08
I have a dialog that gets filled by an ajax call. I want to limit the max-height of dialog and also allow it to be scroll-able if this max-height is exceeded. The code below does exactly what I want. The catch is I can not move the top of the dialog from the top position . I can move it left and right. I can't use center either as the dialog is displayed in a large scroll-able window. If I use firebug I can adjust the top property but cannot find where it is being set to zero. $("#your-dialog-id").dialog({ open: function(event, ui) { $(this).css({'max-height': 500, 'overflow-y': 'auto'}); },

对于有规律的Ajax请求，我们可以分析它的特点，从而抓取一个又一个的Ajax去获取请求，但，有些网站为了反爬，它的Ajax是没有规律的，我们举个例子，拉勾网 我们进入拉勾网，搜索python，检查，切换到network，过滤请求，这里只要Ajax请求，下滑到底部，点击下一页： 图中标有1,2的两个请求，就是包含职位信息的Ajax请求，分别是第一页的和第二页的，我们可以发现，两个Request URL是一样的，也就是说，这里并没有参数让我们区分不同的Ajax请求有什么区别，而且，如果你访问这个Ajax，即使是浏览器也会这样： 更不用说爬虫了。 那针对这样的网站，我们怎么能获取大量数据呢。 我们这次的目的是，爬取详细信息，多页。我们需要，selenium，chromedriver，lxml，MongoDB 先上代码 from selenium import webdriver from lxml import etree import time from pymongo import MongoClient client = MongoClient() db = client['LaGou'] collection = db['lagou_position'] #写入chromedriver路径 driver_path = r"D:\pythontools\chromedriver

I have successfully implemented spring security oauth2 2.0.5 in a spring 4 application. All works fine, i can generate tokens and api requests are properly authenticated. But the problem is that once an api is authenticated with an access token inside a browser based application, the subsequent calls dont need the access token because -it seems spring security relies on the sessionid instead to identify and authenticate the user. - the calls seem to

Edit, some code: I use this functions to load and play an mp3 from the network function loadSoundFile(url) { source = null; var request = new XMLHttpRequest(); request.open('GET', url, true); request.responseType = 'arraybuffer'; request.onload = function(e) {
