GTK 4 C Application doesn't always run (show up) and needs to be killed

gilboonet · January 28, 2023, 8:15pm

Hello, here’s a new description of my problem with my gtk4 C application. When I run the program, then close it, at next run it might hang, one ore more times, then runs again. And I need to kill it for times it didn’t run. Indeed, it runs, but doesn’t always show. Apparently it is because I use a DrawingArea (when I don’t create the DrawingArea I can run/close/run again as many times as I want and it works). Do you have any hints, any thing that could help me find what I need to do ? I’m using DrawingArea on my application for a year now and as long as it was with a GtkNotebook it worked fine, but now I’m simply using it into my main window. I’m already in the process of rewriting this same application with other tools but I would like to know what I can do to have it run properly. I already put code into my previous post about this problem if you want to browse it.

It’d be useful to see what the terminal show if you run it.

There’s nothing shown if I run it from the command line, I added feedback and it normally creates all the widgets and runs the command that shows the window but it simply doesn’t appear. Maybe do I need to add something instead of NULL as last parameter of gtk_drawing_area_Set_draw () but as I already said in my last post I didn’t find what to put here.

You may try that:

Compile your application with debug symbols (-g)
Run your application
If the window doesn’t show up, open a terminal and launch the command: gdb -p <pid>, substituting <pid> with the PID of your program.
From the gdb prompt insert the command thread apply all bt and press enter
Post the output here

It seems to deadlock in a call to Cairo (cairo_rectangle() at main.c:1221)

That’s strange, I’m gonna take a look at the Cairo source code

lb90 · January 29, 2023, 8:17pm

Can you install debug symbols for Cairo and take a backtrace again?

gilboonet · January 29, 2023, 9:10pm

I’m afraid I don’t know how to do that. I tried to install a package called libcairo2-dbgsym, but it does not seem to install it and the snap store hangs.

gilboonet · January 30, 2023, 10:46am

I finally checked up my code, and I found out that I didn’t initialize everything into my main data structure that was used to build the only cairo_rectangle I’m using into the function used to draw the drawing_area. And now it works fine. Thank you again @lb90, your help was really appreciated.
