使用XULRunner时如何在SWT浏览器窗口中打开pdf文件? [英] How can I open pdf files in SWT browser window while using XULRunner?

问题描述

我正在开发一个基于Eclipse的应用程序，其中我需要预览pdf文档作为功能的一部分.截至目前，单击预览"按钮会打开一个提示，用于保存pdf，但不会在所需窗口中直接打开文档.有什么方法可以在XULRunner或应用程序的ini文件中添加任何参数/插件，以便默认情况下可以在窗口中打开pdf? (我正在使用Red Hat Linux 6.5(圣地亚哥))

I am working on an eclipse based application wherein I need to preview pdf documents as part of a functionality. As of now clicking on preview button opens a prompt for saving the pdf but it does not directly open the document in the required window. Is there any way where I can add any arguments/Plugins in the XULRunner or the application's ini file so that the pdf can be opened in the window itself by default ? (I am using Red Hat Linux 6.5 (Santiago))

推荐答案

以下内容仅适用于Linux.首先，您的SWT版本必须为< Eclipse 4.8，请参阅 https://www.eclipse.org/swt/faq.php#browserlinux

The following applies to Linux only. First of all, your SWT version must be < Eclipse 4.8, see https://www.eclipse.org/swt/faq.php#browserlinux

如果您的SWT符合此条件，我知道有2种选择:

If your SWT meets this criterion, there's 2 options I know of:

将插件nppdf.so添加到您的xulrunner安装中，需要在PATH上具有匹配版本的Adobe Reader"acroread"可执行文件(也许acroread版本可以是> nppdf版本，对此不确定)

Add plugin nppdf.so to your xulrunner install, needs Adobe Reader "acroread" executable with matching version on the PATH (maybe acroread version can be > nppdf version, not sure about that)

使用pdf.js:我使用Eclipse 3.8.2，xulrunner 10.0.4esr和pdf.js< 2，例如1.10.100.

Use pdf.js: I got it to work using SWT from Eclipse 3.8.2, xulrunner 10.0.4esr and pdf.js < 2, e.g. 1.10.100.

更新:这种版本组合对pdf文件中的图片有问题，因此我不得不升级到:SWT 4.4和xulrunner24.pdf.js 1.10.100仍然有效，现在2.x也可以使用，但是.

UPDATE: this combination of versions has a problem with images in pdf-files, so I had to upgrade to: SWT 4.4 and xulrunner 24. pdf.js 1.10.100 still worked, 2.x would now also be usable, though.

在xulrunner安装中，创建包含以下内容的文件默认值/preferences/prefs.js(xulrunner.js也可以):

In your xulrunner install, create file defaults/preferences/prefs.js (xulrunner.js also works), containing this line:

pref("security.fileuri.strict_origin_policy", false);

要查看pdf文件，请将嵌入了swt的xul运行器指向

To view a pdf file, point your swt-embedded xul-runner to

file:///<pdf.js-dir>/web/viewer.html?file=<absolute-pdf-file-path>

这可能适用:

但是，我们确实会询问您是否打算将查看器嵌入到您自己的网站中， 它不仅是未修改的版本.请重新设置外观或构建 在它上面.

However, we do ask if you plan to embed the viewer in your own site, that it not just be an unmodified version. Please re-skin it or build upon it.
