I need help with xwindows!
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.
Code:
#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 |
