How to put read number to the graphics window?

[luxer14]

Hello!

Im learning with Free Pascal graphics and I have got one problem, so I would like some help from you guys.

1) Can I put the read number to the graphics window?
For example i write to console number 123, can i write the read number to the graphics window? If yes, how?
2) Can I write text or number right to the graphics window without writing it to the console?

Thank you!

Before answering any of your question: what kind of "graphics" are you learning? graph? lcl? fpgui? winapi? opengl?

Textout may do what you want - certainly wen using LCL.

So you read text in console with readln(), and then want to show it on TForm? Easiest way to display a single line of text is to use TLabel. You can do label1.caption:=s;

Or for multiple lines there is a TMemo, which you can append with memo1.lines.Add(s);

I use graph right now, i tried with outtext, but it can only be used with string type, when i need to read the variable and write it on the graph window

Convert an integer value to a decimal string.
Use function IntToStr.

Forgot to mention something: look at the demos, especially gravwars. It uses graph unit and it uses keyboard to input.
