如何在 Windows 上抑制控制台 window?

How do you suppress the console window on Windows?

basic example Gtk+ app 并将其命名为 main.vala:

using Gtk;

int main (string[] args) {
    Gtk.init (ref args);

    var window = new Window ();
    window.title = "First GTK+ Program";
    window.border_width = 10;
    window.window_position = WindowPosition.CENTER;
    window.set_default_size (350, 70);
    window.destroy.connect (Gtk.main_quit);

    var button = new Button.with_label ("Click me!");
    button.clicked.connect (() => {
        button.label = "Thank you";
    });

    window.add (button);
    window.show_all ();

    Gtk.main ();
    return 0;
}

添加一个简单的 meson.build 文件:

project('gui-test', 'vala', 'c')

dependencies = [
    dependency('glib-2.0'),
    dependency('gobject-2.0'),
    dependency('gtk+-3.0')
]

sources = files('main.vala')

executable('gui-test', sources, dependencies: dependencies)

使用 toolchain from msys2 这可以通过通常的步骤编译成 Windows 应用程序:

meson build
ninja -C build

生成的可执行文件将具有 Windows 控制台子系统 (-mconsole)。

从 Windows 资源管理器启动时,它会打开一个控制台 window。

如何避免在此 gui 应用程序中使用控制台 window?

在可执行文件中设置gui_app: true

project('gui-test', 'vala', 'c')

dependencies = [
    dependency('glib-2.0'),
    dependency('gobject-2.0'),
    dependency('gtk+-3.0')
]

sources = files('main.vala')

executable('gui-test', sources, dependencies: dependencies, gui_app: true)

这是文档结束 in the meson manual:

gui_app when set to true flags this target as a GUI application on platforms where this makes a difference (e.g. Windows)
