App

For apps that want dvui to provide the mainloop which runs these callbacks.

In your root file, have a declaration named "dvui_app" of this type:

pub const dvui_app: dvui.App = .{ .initFn = AppInit, ...};

Also must use the App's main, panic and log functions:

pub const main = dvui.App.main;
pub const panic = dvui.App.panic;
pub const std_options: std.Options = .{
    .logFn = dvui.App.logFn,
};

Fields

config:AppConfig: The configuration options for the app, either directly or a function that
initFn:?fn (*dvui.Window) anyerror!void: Runs before the first full frame, allowing for configuring the Window.
deinitFn:?fn () void: Runs when the app is exiting, before Window.deinit().
frameFn:frameFunction: Runs once every frame between Window.begin and Window.end
