So we need to call at least one of the constructors of the Window class. I created LoginWindow class and it has inherited from the Window class. The toolkit library is well-designed and it’s easy to use, but before everything, we need to learn some information and concepts. Rich set of components such as buttons, labels, text entry, text view, time field, radio buttons, checkboxes, dialogs, windows, menus, list views, frames, progress bars, scroll bars, scroll views and a hex editor/viewer.This version tries to be console-agnostic and instead of having a container/widget model, only uses Views (which can contain subviews) and changes the rendering model to rely on damage regions instead of burdening each view with the details. The original gui.cs was a UI toolkit in a single file and tied to curses. This is an updated version of gui.cs that I wrote for mono-curses in 2007. Miguel de Icaza is the author of this library.

Gui.cs is a UI toolkit for creating awesome console-based applications with. Here is an example of a framebuffer mode: The framebuffer is used on the Linux terminal. Not like text-mode, Framebuffer uses graphics, pixels. For instance, here(or in Ali Commander) I used box-drawing characters to draw my UI.

For eg IBM PC Code page 437 offers several characters, such as box-drawing characters (like edges, lines, etc) that many applications used them to draw their UI. In text-mode application can use characters to display their UI on the terminal.

Literally, the screen will be considered as a uniform rectangular grid of character cells. Text-mode: is a terminal display mode in which content is represented on the display in terms of characters and not individual pixels. There are two modes of terminal display, Framebuffer, and Text-mode:
