[PATCH 3 of 3] Easy panning with the left mouse button

by 4winter＠informatik.uni-hamburg.de

# HG changeset patch # User Justus Winter <justus.winter(a)informatik.uni-hamburg.de> # Date 1236616924 -3600 # Node ID 46c62dde8967ae87914d0fbcc0ba7df61853750c # Parent 78c0fa261c84df53da7f69cc8f33dc85fa152f9c Easy panning with the left mouse button This is particulary useful for embedded devices with touch screens. In order to select text you have to double click and drag the pointer. Note that this functionality is disabled by default and can be enabled by the easy_panning directive in the configuration file with the exception of the selection behavior which is located in dw/selection.cc and lacks a reference to the prefs struct by design (dw is a toolkit and frontend agnostic). I think that dw needs an interface to tweak it's behaviour ie dw_config(DW_DOUBLECLICK_TO_SELECT, true).

[patch]: remove the BW_* flags

by onepoint＠starurchin.org

a_Bw_stop_clients() is always called with the BW_Root and BW_Img flags set, so we can remove those flags. That leaves only the BW_Force flag, so we can remove that too and change the flags argument to a boolean that indicates whether to force. Regards, Jeremy Henty

Server-side CSS detection?

I don't think there is a way to detect CSS support other than checking the reported user agent, as CSS only changes the appearance on the client side. However dillo is currently getting some initial CSS support, so for dillo this problem may just disappear in the future. Regards, Johannes

Server-side CSS detection?

by rn214＠cam.ac.uk

Dear All, I've just joined this list, so I hope I'm posting this in the right place. I'm a webmaster, and I want to make sure that my site works properly in all browsers including dillo. However, some of the new code (*) in my site relies on CSS properties such as display:none and does not gracefully degrade. If a browser has no CSS support, the newest stuff breaks in a very ugly manner, whereas most of the CSS I've written to date fails gracefully (we don't really care if some text-colour is wrong). So my question is, how can I detect CSS support server-side? I don't need to know precise details of the CSS-support; I just want a simple yes/no. So Netscape 4.6 would be "yes", whereas Dillo 0.8, and links/lynx/w3m/googlebot would be "no". I don't want to do it by user-agent sniffing, and, if at all possible, I don't want to rely on javascript (there are plenty of people who have CSS-capable browsers with JS turned off). I've had no luck from google, so I thought I'd ask here, as you'll know the best way to do this. Thank you for your help, Regards, Richard (*) for example, I display HTML tooltips like this: span.tool { position: relative; cursor: help; } span.tool span.tip { display: none;} span.tool:hover span.tip { display: block; z-index: 100; position: absolute; top: 1.6em; left: 0; width: auto; padding: 6px; border: #F00;} <span class='tool'>this is the link <span class='tip'>Here is some <b>html</b> for the tooltip </span> </span> i.e. the tool.tip is normally hidden by display:none, but is displayed as result of the hover action. If a browser doesn't support the CSS display:none property, that will render in a very ugly way, with the tooltip contents displayed inline. So I want to have a way to fall-back (server-side) to: <span title='this is the tooltip, without html'>this is the link </span> My intention is to do this server-side, using a session-variable after testing whether the client supports CSS. But how?
