librocket GUI support

[rdb]

File a bug report on Launchpad with some simple sample code that clearly illustrates the problem. Thanks!

[texugo]

Done

Thanx

Hasn't the Ubuntu Precise build no support for librocket? I tested it with 3 different .debs, but everytime I got the "ImportError: DLL loader cannot find _rocketcore."-thing. For now, it's possible for me to switch to WinXP for a while, but I would be happy to develop under Ubuntu

Texugo: I do believe this bug is actually already known and has been fixed in the 1.8.1 branch.
I have the same issue. Just waiting for 1.8.1 to be released.

Another question: I need to handle left and right clicks on some element, and I realized that only the left clicks were received by my event listener.
I'm fairly certain the Rocket "click" event checks for every kind of clicks (it has a "button" parameter... doesn't make much sense if that parameter is bound to always be '0').

Has anyone ever managed to get something else than left clicks from Rocket ?

Hi, I had a few questions for (probably rdb) you guys.

Are the panda3d's rocket module using a CVS version of Rocket, or the one found at http://librocket.com/download

The libRocket builds found on the download page are from over a year ago, and are missing several bug fixes that my project would require, is there any chance we could build against a CVS version of libRocket for panda3d 1.8.1? Or should I talk to the libRocket developers about updating the downloads on their page?

In specific the CVS builds of Rocket include these things I'd like:

Clipboard support (https://github.com/lloydw/libRocket/blo ... pboard.cpp)

and (this is direly required for me)

the fix for "textarea" elements to be disabled and still render text: http://forums.librocket.com/viewtopic.php?f=2&t=766


Thank you,
~powerpup118

Hi again,

I've actually found a small workaround for my particular use case of the "textarea" element, so that I no longer require the patch.

I believe it's still a good idea to update to recent versions of libRocket instead of old builds, I can live without it though.

My apologies for speaking so soon,

Hi all. I'm running Debian Squeeze and have installed both 1.8 and 1.9, but I'm getting the "ImportError: DLL loader cannot find _rocketcore" that others have reported in this thread.

I also don't seem to have anything related to rocket in /usr/lib/panda3d

Is there a particular version I should be looking for?

[rdb]

Perhaps your build of Panda3d was not compiled with support for librocket. Which build did you install?

[Panza]

I installed the latest 1.8 and 1.9 packages from panda3d.org:

panda3d1.9_1.9.0+cvs20120923~squeeze613_i386.deb

and

panda3d1.8_1.8.0~squeeze_i386.deb

None of the Precise builds includes rocket:
WARNING: Could not locate thirdparty package rocket, excluding from build

[Nemesis#13]

However, you can use the Oneiric builds with precise just as well, and they're built with librocket.

A sample can be found here: https://github.com/nemesis13/Azure--Inf ... sample.zip

After unpacking start it by running

Code: Select all

python test.py

The sample consists of a simple main menu with a few entries, of which "adventure" prints a string to stdout, "quick game", "options" and "credits" show a full-screen modal dialog with some text on it and "exit", which quits the application. In the background you should see an airplane hanging around.

The rocket-included debugger is also activated by default. I leave it to the reader to disable it at will. (It's in test.py)


I hope it helps. If you have questions, just shoot it out.

Here two screenshots of how it's supposed to look:


PS: please don't search for the project, it's paused for at least a few years.

I'm trying to get librocket to work with fonts besides the provided Delicious. The call to LoadFontFace returns True, which the librocket api says means it's loaded correctly. I just can't figure out what on earth to put in the font-family designation to get it to render with my own font. Is there some way to query all of the font-familys that the renderer accepts?

[rdb]

This is covered in the librocket manual: http://librocket.com/wiki/documentation ... nual/Fonts

[Tober]

Is there an example of how to do it in python instead of c++? I can't find any reference to the values WEIGHT_NORMAL or STYLE_NORMAL in the devel python API. If I guess that they're ints, it crashes with this:

Code: Select all

    print LoadFontFace("code/ui/fonts/MyriadPro-Regular.otf","Myriad",1,1)
Boost.Python.ArgumentError: Python argument types in
    _rocketcore.LoadFontFace(str, str, int, int)
did not match C++ signature:
    LoadFontFace(class Rocket::Core::StringBase<char>)


[rdb]

Huh, maybe they don't expose that through the Python interface then. Perhaps you should instead simply find out what the family name of that font is by examining the font in a tool that can display the metadata of font files?

[Tober]

I figured it out. Librocket only accepts font-family names with spaces in them if you enclose it in double quotes. I was using single quotes, which works in Firefox css, at least.

[rndbit]

i wanted to make sure.. is Rocket::Core::Factory::ClearStyleSheetCache() somehow exposed to python? i cant find it anywhere and its vital for rapid ui development and testing as css files are loaded from cache thus modifications are not reflected in reloaded document.

[rdb]

This is really a libRocket question, I would suggest that you search for the function in the libRocket Python API reference.

[rndbit]

right.. if only project was not dead-ish. do you happen to have archived copy of librocket documentation by any chance? official page aling with the wiki is down since idk when.

[Nemesis#13]

Looks like working for me: http://librocket.com/wiki/documentation

[Tober]

The website was temporarily down for maintenance a few days ago. Was kind of annoying considering how unpythonic their python bindings are...

[rndbit]

Bindings are totally not of greatest quality. I was right about ClearStyleSheetCache not being exposed so i packed up latest librocket release code. In addition i added ability to set int/float (pixel) values as element.style attributes.
