Video is a Glimmer DSL for SWT Custom Widget for playing videos via the video Glimmer DSL keyword.
Featured in Math Bowling 2
This has been tested and confirmed to be working on:
- Mac
- Windows
- Glimmer DSL for SWT application, Glimmer DSL for SWT custom shell, or another Glimmer DSL for SWT custom widget
- JRuby version required by Glimmer DSL for SWT
- Java version required by Glimmer DSL for SWT
Add the following to a Glimmer DSL for SWT application Gemfile:
gem 'glimmer-cw-video', '1.1.0'Run:
jruby -S bundle
(or just bundle if using RVM)
When reusing the video custom widget in a Glimmer DSL for SWT custom shell or custom widget, you can follow the same steps for a Glimmer DSL for SWT application, and then add a require statement to your library file:
require 'glimmer-cw-video'
# ... more require statements followHere are the options to pass in as hash arguments to the video widget keyword (see in Samples):
autoplay(true [default] or false): plays video automatically as soon as loadedcontrols(true [default] or false): displays controlslooped(true or false [default]): plays video in looped modebackground(Glimmer color [default: white]): sets background color just like with any other widgetfit_to_width(true [default] or false): fits video width to widget allotted width regardless of video's original size. Maintains video aspect ratio.fit_to_height(true [default] or false): fits video height to widget allotted height regardless of video's original size. Maintains video aspect ratio.offset_x(integer [default: 0]): offset from left border. Could be a negative number if you want to show only an area of the video. Useful when fit_to_width is false to pick an area of the video to display.offset_y(integer [default: 0]): offset from top border. Could be a negative number if you want to show only an area of the video. Useful when fit_to_height is false to pick an area of the video to display.

Run this command after installing the gem to list available Video samples via the Glimmer Meta-Sample (note that you would have to restart the Glimmer Meta-Sample after every Video sample run because of an unresolved minor issue):

- Check out the latest master to make sure the feature hasn't been implemented or the bug hasn't been fixed yet.
- Check out the issue tracker to make sure someone already hasn't requested it and/or contributed it.
- Fork the project.
- Start a feature/bugfix branch.
- Commit and push until you are happy with your contribution.
- Make sure to add tests for it. This is important so I don't break it in a future version unintentionally.
- Please try not to mess with the Rakefile, version, or history. If you want to have your own version, or is otherwise necessary, that is fine, but please isolate to its own commit so I can cherry-pick around it.
