Is it possible to get height of window's title bar?

Question

I am working on some code about capturing mouse location. I have a frame created by using wxWidgets, and I am working on an issue which I need to get the title bar height. Is there a good way to get the size of title bar?

Here is a simple illustration of what I need:

Did you just assume that the title bar always sits on top of your window? [Big mistake](https://en.m.wikipedia.org/wiki/FLWM#/media/File%3AFLWM_Screenshot.png). — n. m. could be an AI, Apr 09 '19 at 13:22

wxWidgets provides a mechanism for this (and much else beside) called wxSystemSettings::GetMetric.

static int wxSystemSettings::GetMetric(wxSystemMetric index, wxWindow* win = NULL);

You can retrieve 'global' values by leaving win as NULL or you can pass in a specific window.

https://docs.wxwidgets.org/trunk/classwx_system_settings.html#aa18e3b5794dc4193c4b0668d28d4933a

The metric you probably want is wxSYS_CAPTION_Y.

`wxSYS_CAPTION_Y` is the thing I am looking for. Thanks for the great documented response. — Tunahan, Apr 09 '19 at 15:31

It should be the y coordinate of what wxWindow::GetClientAreaOrigin() returns.

Both of the `x` and `y` values of `wxWindow::GetClientAreaOrigin()` returns zero, then I couldn't get the right thing. – Tunahan Apr 09 '19 at 13:16
