Hi!

I am really having trouble with xwindows.

I have managed to create a colour chooser, that creates a rectangle and allows the user to change the colour by typing in values accordingly.

I want to be able to create a moving rectangle that will rotate clock-wise on the same window as my previous changing colour box.

The code i have so far is as follows.

 



#include "mywin.h"

#include "button.h"

#include "textwin.h"

#include <stdio.h>


Button B1, B2;       /* Buttons must be declared, then Created */

                 /* before they become live */


Textwin red, green, blue;


char mousestr[100];



Colour makeColour(int red, int green, int blue)

{

	return((red&0xff)<<16|(green&0xff)<<8|(blue&0xff));

}


void move()

{


}


void draw2()

{

    XClearWindow  (display, main_win);

    XFillRectangle(display, main_win, gc_1, 50, 50, 100, 100);

    XSetForeground(display, gc_1, makeColour (atoi(red.text), atoi(green.text), atoi(blue.text)));

    XFlush(display);

}


void B1fn()

{

    draw2();

}


void B2fn()

{

	move();

}


void draw()       /* AKA FormPaint */

{

    XClearWindow  (display, main_win);

    XFillRectangle(display, main_win, gc_1, 50, 50, 100, 100);

}


int main()

{

    setupX();

    make_window(600, 400, "Colour Chooser");    

    Textwin_Create(&red, 10, 200, 170, 28, "Red", "red");

    Textwin_Create(&green, 10, 250, 170, 28, "Green", "green");

    Textwin_Create(&blue, 10, 300, 170, 28, "Blue", "blue");

    Button_Create( &B1, 10, 350, 170, 28, "Double-Click to update", &B1fn);

	Button_Create( &B2, 200, 200, 170, 28, "Start Revolving Square", &B2fn);

    event_loop(subwindowlist);

    return -1;

}

Anybody have any idea at all how i can make the move() function create a rotating rectangle?!

Any help on this at all is greatly appreciated
