Hi everyone!
Whoops, I now realized I never made that post about gestures, I was too busy fixing up the remaining code to work with it 
. First a small recap of progress since last week: I’ve made a pull request regarding the various GUI-improvements, as can be seen on https://github.com/scummvm/scummvm/pull/361 . Also I’ve worked a bit on the other pull-request, the new version of the code in the backend checks if 32-bit is wanted (by a flag in the config file, as before), and sets the bit-depth accordingly.
As for midterm, the 32-bit code and the GUI-improvements, especially the gradient effect on the bevels, took a bit longer than expected. What’s next is to create widgets for the new touch-based theme, before working on the theme itself. From the current mockups, it seems like a scrollable canvas-type widget needs to be implemented, and also some kind of picture-button class. These need to be able to respond to gesture-events, and the other “old” widgets also need to be able to respond to these events. After that is done, work on the new theme can commence.
Until next time!
