RQT not showing icons in OSX

edit

rqt uses the tango-icon-theme for the icons. This package is available on ubuntu, but is not available through Homebrew (yet).

For now the dependency is left unresolved:

https://github.com/ros/rosdistro/blob/master/rosdep/osx-homebrew.yaml#L381

rqt (specifically rqt_bag in this case) might better handle this by falling back to system icons, but this may not be possible.

As a work around you can download, build and install the tango-icon-theme from source:

http://tango.freedesktop.org/releases/tango-icon-theme-0.8.90.tar.gz

By following the instructions here:

http://tango.freedesktop.org/Installation#Tango_Icon_Theme

This should allow rqt to show the icons, but I have never tried it myself.

EDIT:

I have created the required tango-icon-theme and icon-naming-utils formulae:

https://github.com/ros/homebrew-groovy/blob/master/icon-naming-utils.rb https://github.com/ros/homebrew-groovy/blob/master/tango-icon-theme.rb

If you already have the ros/groovy tap, then just do brew update, otherwise do brew tap ros/groovy.

I updated the rosdep entry, so now the tango-icon-theme should get installed automatically when following the source installation instructions:

https://github.com/ros/rosdistro/commit/9b35f250af19b253f278bfdb45af32fe961a32d1

Then I had to patch qt_gui_core to include /usr/local/share/icons to the icon search path for rqt:

https://github.com/ros-visualization/qt_gui_core/pull/17

So if you install tango-icon-theme and apply that patch to qt_gui_core then you get something like this:

So there seems to be some other problem related to button positioning in rqt_bag.

I have opened an issue:
