Anybody have some useful websites besides gtk.org ?
I traversed through a few and am still trying to digest it.
I am playing around with an example to create a custom widget in a window to understand the basic functioning of gtk. This way i am a bit familiar with gtk. Because i expect when i try the open cv examples because of older and newer versions of all the different software packages that are used, to experience some issues.
I already made and examined some examples, almost all these examples windows cross compile fine and run on the raspberry pi 3 except one. Since i use gtk3.0 most of these examples cause a lot of deprecated warnings. But it compiles and works except one. I can solve the warnings later on when i have a real project and not a study project.
The nicest example about a custom cpu widget does not want to compile at all.
Now i am in the process of learning what steps must be taken to create a custom widget to reverse engineer the example and get it to function.
I disabled the custom widget code and added a button for the test instead of the custom widget and the basic code is fine. I looked through the basic main and did see nothing wrong. It seems fine.
http://zetcode.com/gui/gtk2/customwidget/
I am now reading this page :
https://www.gtk.org/tutorial1.2/gtk_tut-22.html
But some more sites would be nice so i can compare them.
edit:
Sigh.
I missed another example that does not work.
At least 2 graphic ones do not work.
Software changes so fast that the examples never work anymore
