Guitarix: Some Progress

Freitag, den 27. März 2015

gx_progress_1gx_progress_2You guys know Sisyphus? Today I fought with a strange problem – I wasn’t able to style widgets in gtkrc files for user interfaces built by Glade. The names given in the UI were set which resulted in “id” attributes for the object-elements in the glade XML. For testing purposes I added a property with the attribute name=”name” and the text node containing the name of the widget to one of the objects and guess what…

I didn’t find any hint about that behavior on the internet. Problem was that editing and saving the files in Glade stripped all those properties again. So finally I wrote a short python script which crawls through all our glade files adding/updating the objects name properties depending on the “id” attribute of the objects element itself.

The screenshots show the actual state. No widgets at all by now but the pure GTK stuff is progressing. Finally we  got rid of the pixmap engine.

Guitarix: First Steps in Codebase

Montag, den 23. März 2015

Splash GX_Mono_Preamp_Ardour GX_Stereo_Preamp_Ardour guitarix_workinprogressMy weekend was quite productive. As a finger exercise I created a new splash screen and changed the design of the first two LV2 plug-ins – Preamp and Stereo Preamp. After that I started touching the “real” code and introduced the new background tiles and screws. Lots of code is already stripped but still a long way to go as you can see on the quite distored screenshot.
