Add Qt help view

[tonka3000]

Add Qt help webview. The Impl. just use the word under the cursor (no selection!) and just use the Qt docs website https://doc.qt.io/qt-5 . The word will be attached in lowercase. QWidget would look like https://doc.qt.io/qt-5/qwidget.html

Closes #39

Thanks! Works for me. Is it possible to add search on the page (via Ctrl+f) and the ability for manual search using https://doc.qt.io/qt-5/search-results.html?q=requestText?

I also noticed that you use GitHub Actions. Could you add something like the following to the CI? This will allow to just download the extension after CI without manual build.

• CTRL + F seems not to work in VSCode webview AFAICT
• Manual search should be possible via another command
• Upload CI artifacts should also be possible

I will try to find some spare time in the next few days to check this points.

Not sure if this is related, but a similar problem has been resolved in vscode-godot-tools.

Yeah, it would be nice. Thanks!

"Find" works (take some time to process) when you click on the area above the view and then press CTRL + F. When you click in the view it will not work. VSCode seems not to support the find widget with iframes correctly, see microsoft/vscode#96307

Thanks for the info!

Hey @Shatur95 ,

I've added a search command for the Qt help, but there is a problem. The search results are links with target="_blank" which is not supported by VSCode webviews with iframe, so you can not click them. When you press the middle mouse button it will open the link in the external browser and that is the only way how you can click them. Maybe the simplest idea to fix that is to open the search directly in the external browser.

I've added artifacts to the build CI jobs, so you can easily try it out.

Thank you! Tested, yes, works for me. If there are so many restrictions in embedding, maybe will be better to just show all documentation in browser?

Hey @Shatur95 ,

I've also add external browser support. By default the extension launch the webview inside VSCode, but you can turn this off by just set qttools.useExternalBrowser to true. I've update the README.md where I list all the features and limitations.

Let me know I you like it or you miss something.

Thanks, just what I need.
