TitleBar and borders

[briler]

Is it possible to remove the titlebar and borders of the main window?

[lalala]

to remove the borders, you can override ResizableWindow::getBorderThickness() in your main window:

BorderSize<int> getBorderThickness() override { return {}; }

and to remove the titlebar :

setUsingNativeTitleBar (false);
setTitleBarHeight (0);
