Get element currently under mouse without using mouse events

由 被刻印的时光 ゝ 提交于 2020-01-11 09:15:06
问题 WRT building a Firefox Add-on. Is it possible to get the element under the mouse via some XPCOM or javascript method? (non-js-ctypes please as that requires OS specificity) I want to detect what is under the mouse when user presses Ctrl + Shift + M . Right now I'm adding a mouseover listener to the document when the user presses this hotkey, so I can get the element under the mouse when he moves it, but not the element that was under the mouse exactly when he pressed the hotkey combination.

问题 I'm creating an XPCOM component using a tutorial as a reference. However, when I run the following command it completes successfully but doesn't produce any .h file: xpidl -m header -I [XUL_RUNNER SDK\IDL] myfile.idl Why is that? Is XPCOM outdated? 回答1: No, XPCOM is not outdated but this tutorial is. The documentation recommends using pyxpidl: header.py -I [XUL_RUNNER SDK\IDL] -o myfile.h myfile.idl 来源： https://stackoverflow.com/questions/11857907/creatition-of-xpcom-components

Firefox bootstrapped extension: Get native HWND handle of the browser window

由 被刻印的时光 ゝ 提交于 2020-01-03 03:20:29
问题 I have an external application and I want it to display some information on top of the browser window. My bootstrapped extension needs to pass the browser window handle (native HWND) to my application, along with some other useful information about the window. I'm able to do the communication between them, the only thing that is missing is a way to get the native HWND of the Firefox window. I read a lot about it and although I belive it's possible, I couldn't find a working solution. Here's

How to implement XPCOM component (nsIContentPolicy) in bootstrapped Firefox extension

由 旧巷老猫 提交于 2020-01-01 11:37:07
问题 I have a bootstrapped extension for Firefox. And now I want to implement nsIContentPolicy XPCOM component. I wrote a component module code. And now I want to register this component. The reason I want to register component is that I want to add my component to nsICategoryManager.addCategoryEntry with "content-policy" category. var {Cc, Ci, Cu} = require("chrome"); Cu.import("resource://gre/modules/XPCOMUtils.jsm"); //console.error("Running interceptor"); function Interceptor() } Interceptor

How can I implement a content converter in Firefox for all page elements?

由 自闭症网瘾萝莉.ら 提交于 2020-01-01 10:03:46
问题 I'm attempting to port over an Internet Explorer plugin to Firefox, but I'm not sure where to look for what I need. Basically I need to be able to filter all content that is received by the browser with a certain Content-Type header. I tried implementing a stream converter, and this works, but only for the top-level document in the page, frame, or iframe. I had the same problem with IE, and getting around it was really hacky, and since I would ideally like this to be cross platform I would

What is missing in my nsIContentPolicy Firefox/IceWeasel extension XPCOMponent implementation for the shouldLoad to be called?

由 泄露秘密 提交于 2019-12-25 08:25:42
问题 In short Why, based on the code detailed below, is the shouldLoad function not called? Longer version My goal I am trying to construct a Firefox/Iceweasel extension that will cancel/redirect certain url requests. Background Based on what I have seen on the web, one way (if I want to intercept every request and not just the top document) to do this is to make an XPCOM component that implements the nsIContentPolicy interface, and register that component in the extension, and have the shouldLoad

Failure while calling nsIX509CertDB.nsIX509CertDB from command line

由 我是研究僧i 提交于 2019-12-25 05:07:05
问题 I'm trying to develop a FF extension that calls nsIX509CertDB.nsIX509CertDB. When calling this function from a xpcshell I alwas receive a error 0x80004005 (NS_ERROR_FAILURE). I suspect it to be failing since in a xpcshell environment I can not be prompted for the password. Is there any way to provide it from the command line?
