GtkApplication

[mabdelouahab]

GtkApplication is the cornerstone for building robust and flexible desktop applications using the GTK library. It provides a comprehensive infrastructure for managing the application lifecycle, handling events, and window management. With GtkApplication, developers can focus on designing the user interface and implementing the application logic, rather than dealing with complex technical details. In short, GtkApplication is a powerful tool that helps accelerate application development and deliver a better user experience

Hi mabdelouahab
Thanks for the demo code.
After installing UASM and GTK on my Mint (v.22) OS, I was able to compile and link the asm file.



I had some fun tweaking the build.sh file, but finally got it to work.

Code Select Expand

    #!/bin/bash
    uasm -elf64 hwgtkapp.asm
    gcc -o hwgtkapplication hwgtkapp.o -z noexecstack -lgio-2.0 -lgtk-3 -lgobject-2.0 -fno-pie -no-pie
    ./hwgtkapplication

This is very exciting as it opens up a huge opportunity for macro frameworks such as ObjAsm.
