GML Usage

How to use GML in SerenityOS C++ applications

Include compile_gml() your applications CMake file. The header file name and GML string name are not fixed but must follow this convention.

compile_gml(MyApp.gml MyAppGML.h my_app_gml)

Include the name of the header file that will be compiled from your GML file in your SOURCES.

set(SOURCES
    MyAppGML.h
)

You can then reference the variable you set (e.g. my_app_gml) in your main C++ file using load_from_gml().

load_from_gml(my_app_gml);

From there, you can use find_descendant_of_type_named to select widgets from your GML by their name property.

@GUI::Button {
    name: "mem_add_button"
    text: "M+"
    fixed_width: 35
    fixed_height: 28
    foreground_color: "red"
}

Is referenced using...

load_from_gml(calculator_gml);
m_mem_add_button = *find_descendant_of_type_named<GUI::Button>("mem_add_button");
