Visual viewport detection in Firefox mobile browser

由 蓝咒 提交于 2019-12-08 02:36:29
As the subject says, I need these zoom-tainted viewport dimensions (CSS-pixels) in Firefox mobile browser. How do I extract that? In webkit browsers it goes by window.innerWidth / innerHeight and works fine, but I just can't find the corresponding values for Firefox. I had the same problem and came up with the following solution: Place a zero-pixel size "dummy" div in the bottom right corner of the screen (using "position:fixed") and query its position via getBoundingClientRect().left/top, which gives the width/height of the visual viewport. Example code (querying only the width): <div id=

Data transfer via bluetooth between paired Android and Raspberry PI

由 早过忘川 提交于 2019-12-08 02:31:23
问题 I am working on a project where I need to transfer data between android and raspberry pi via Bluetooth. However, I am new to this and I don't have deep understanding on what happens when two devices are paired. Based on assumption that the two devices of interest are already paired, where would the starting point be for programming for such task? I've been reading on BluetoothSocket, but I am still unsure of where to start. Can anyone help me please? Thank you so much in advance! 回答1: I've

How to Include SVG file as <input> background

由 做~自己de王妃 提交于 2019-12-08 02:15:03
问题 I'm a newbie to the SVG world, just started experimenting today. I'm trying to create a mobile site where the primary graphics are all scalable, thus supporting all display resolutions. I created an svg file for my input (currently type="image"), and suprisingly the results are as expected in my code editor (Coda). In testing (mobile Safari, DT Safari and DT FF), the input displays broken image path placeholder (the oath is correct because I can right-click to download the file). How do I go

Connection Closed Gracefully Indy TCPServer Mobile App Delphi XE8

由 独自空忆成欢 提交于 2019-12-08 02:06:19
问题 I am using Indy TCPClient/TCPServer to verify registration of a mobile device. The process is fairly straight forward where I read an identifier on the Server Side, validate it against the database control file and send back a response to the client. Everything appears to work correctly for the most part but periodically I get the EIDConnClosedGracefully Exception on the Server Side. I can't seem to pinpoint exactly where the connection is being closed improperly. In fact, it appears that the

由 本小妞迷上赌 提交于 2019-12-08 02:03:55
问题 My school organization currently has a website that incorporates JQuery and uses "dialog" pop up boxes (JQuery-UI?). I am making the website responsive but do not know how to go about making the dialog boxes responsive.

I know my question is a little vague but I was wondering if anyone has a simple solution? Here is what I believe to be the code for one of my pop-up boxes. ( I don't

How to listen for email messages

由 你说的曾经没有我的故事 提交于 2019-12-08 02:03:46
问题 Is there a way to listen for incoming/outgoing email messages or access the inbox directly? I read that since there is no default mail client in the Android SDK it is not possible unless the client used on the phone implements some custom mechanisms. Is this still the case? 回答1: Emails are not part of the Android OS so you cannot code a global Broadcast Receiver (like you would for incoming SMS). The obvious workaround is to code Broadcast Receivers for the top X most popular email clients on

问题 I have read a lot of articles and looked for solutions to detect mobile devices. Actually a came across https://github.com/serbanghita/mobile-detect but it's a quite massive php class.
