Close Button and other types of buttons

Hi.
Thanks for taking my question.
How to make screen display close button on a window?
Does it depend on display technology?

Any window will have the little 'x' in the upper right corner, but unless you program some shut-down actions, it might leave things in a bad state.

You should use a graphics package that provides general utilities like toggle buttons, radio buttons, text placement, user typed input fields, etc. Then you can program a button as an 'Exit' action and have it trigger any clean-up actions before the program is killed. It should do things like close files, complete any pending operations, ask the user if he is sure he wants to close the program or save results, etc. Unfortunately, I am not up to date on the current graphics user interface packages for different operating systems.

You should specify what operating system and language you are working with if you want good help. If you are programming with Python, you might be interested in this.

Short on details.

Are you making a graphical program?
what operating system are you using, what GUI package for what language?
It shouldn't depend upon the display technology per se.

How to put a button on the top right corner without using any library? Can you describe hardware (display technology) mechanism with little pseudocode that puts a button right up there?

You should probably be more specific about what level of code you are talking about. IMO, you should be careful not to use such low level code that you have to worry about the details of the specific monitor hardware. If you deal with the buffer in memory, that avoids a lot of hardware considerations. I recommend that you use a double-buffer option or strange things can happen in different situations. I have only dealt with relatively high level graphics utility software. Even the high level utilities should have the capability of drawing individual line segments. Working at that level would be more tedious.
