Print a string sequentially

[chouahm2]

Hi everyone,

Anyone knows how to print a string sequentially.
Basically, i made an application (with a GUI) and i want on the screen to print out a string sequentially.

For example: Lets say:
String str = "Hi my name is Mans";

What i would like to do is to print out the string str, character by character with a timer after each character printed out.

See the printing output is the same way as we are writing on the keyboard.

For example, i wanna print out "Hi my name is mans"
So the output is gonna be like:
H (timer = 2seconds) i (timer = 2seconds) m (timer = 2seconds) etc...

Is this clear?


Thanks for u help...

Use a loop to print each character and a sleep function to pause the loop

Thks for replying, but this idea came up to my mind first when i wanted to print the string sequentially.

The sleep() method doesnt do what you are expecting, it freezes the program and then print all the characters at once.

I need something that freeze only the loop when one character has been printed.

Any Idea?

You need to flush the stream after each character
Which sleep function did you use?

Hi, i am actually using wxWidgets and actually its not a string but a wxString, anyway they are similar.

For the sleep function, i just used:
sleep(1);

Here i the code :

int j = 0;
	for (int i  = 0 ; i < explanation.Length() ; i++)
	{
               // This print the substring(character by character)
		m_dialog->WriteText(explanation.SubString(j,i));
               j++;
		sleep(1);
	}

I never used wxWidgets so I can't help you with this.
Make sure that you don't have to explicitly refresh the dialog to see the result

So what command will be used to activate the cursor during the sleep period?.....and who is going to be able to read all these disjointed characters over x lines?
Would you not be better off with a string like:
string s={"A m.....I.....n o t.....j u s t.....s o......s t u p i d "};
cout<<s;
Note: use spaces (" ")I.L.O. dots(.) when formating .
