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
