memory leak ?

[kculin]

I have been playing with customwidget.zig example and noticed that
zfltk does not execute deinit method.
Does zfltk calls deinit on custom / wrapper widgets or semething has to be done manually

Hello

By default in FLTK, widgets are managed by their parent widgets. So you’re not the actual owner of the widget so you you don’t need to deinit them.

Thank you, for such fast answer,

I modified

pub fn deinit(self: *Switch) void {

• std.debug.print("Deinit\n",.{});
  self.box1.deinit();
  self.box2.deinit();
  self.label.deinit();
  app.allocator.destroy(self);
  }
  and it did not execute unless i added defer sw.deinit();
  so while fltk did managed child widgets (c++ objects), what about zig structs that run
  pub fn init(opts: Options) !*Switch {
  var self = try app.allocator.create(Switch);
  ...
  }
  and dont run
  pub fn deinit(self: *Switch) void {
  ...
  app.allocator.destroy(self);
  }

Yeah the Switch in the customwidget example is a custom widget which returns an allocated pointer, so that needs cleanup.
