Thread: Adding Fields to your OpenGL GUI

GLUT has support for printing bitmap fonts. It would be pretty easy to output a letter when the user types it.

How far along in OpenGL are you again?

Coding up a textbox in OpenGL isn't that hard - heck I've done it in QBasic before!

Just create an algorithm that converts the value of a key into the X and Y location of a bitmap font letter and blit that.

Finally figured it out...
I know what you're saying frobozz, i was trying to get around writing code for every single key....

but... its already done in openGL, here is the code I used..

Code:

int keys[256];

void type_text( char tekst[], int max )	{
		int d = strlen( tekst );
		for( int w = 32; w < 126; w++ )
			if( keys[ w ] && d < max ) {				
				tekst[ d++ ] = w;
				keys[ w ] = false;
			}
		if( keys[ 8 ] ) {
			if( d > 0 )
				tekst[ --d ] = 0;
			keys[ 8 ] = false;
		}
	}

i'm sure theres another bit of code that implements it, but thats the source

i've only been doing openGL for a couple months, 6-7
