Přepis XWindowManageru do D – C / C++ – Fórum – Programujte.com

Dobrý den,

co jiného může být lepším základem pro vlastní XWindowManager, než TinyWM... :) (50 řádků kódu...) V C to jede:

https://github.com/…ter/tinywm.c

Ale přepis do D:

 

import std.c.linux.X11.Xlib;
import std.c.linux.X11.X;

// gdc ./main.d /usr/include/d2/4.6/std/c/linux/X11/Xlib.d -o refuja -lX11

int main()
{
	Display *display0 = XOpenDisplay(cast(char*)0);
	XWindowAttributes winAttributes;
	XButtonEvent start;
	XEvent xEvent;

	if(!display0)
		return 1;

	XGrabKey(display0, XKeysymToKeycode(display0, XStringToKeysym(cast(char*)"F1")), KeyMask.Mod1Mask, DefaultRootWindow(display0),  cast(Bool)true, GrabMode.GrabModeAsync, GrabMode.GrabModeAsync);
	
	XGrabButton(display0, 1, KeyMask.Mod1Mask, DefaultRootWindow(display0),  cast(Bool)true, EventMask.ButtonPressMask | EventMask.ButtonReleaseMask | EventMask.PointerMotionMask, GrabMode.GrabModeAsync, GrabMode.GrabModeAsync, None, None);
	
	XGrabButton(display0, 3, KeyMask.Mod1Mask, DefaultRootWindow(display0), cast(Bool)true, EventMask.ButtonPressMask | EventMask.ButtonReleaseMask | EventMask.PointerMotionMask, GrabMode.GrabModeAsync, GrabMode.GrabModeAsync, None, None);

	start.subwindow = None;
	
	while(true)
	{
		XNextEvent(display0, &xEvent);
		
		if(xEvent.type == EventType.KeyPress && xEvent.xkey.subwindow != None)
			XRaiseWindow(display0, xEvent.xkey.subwindow);
		else if(xEvent.type == EventType.ButtonPress && xEvent.xbutton.subwindow != None)
		{
			XGetWindowAttributes(display0, xEvent.xbutton.subwindow, &winAttributes);
			start = xEvent.xbutton;
		}
		else if(xEvent.type == EventType.MotionNotify && start.subwindow != None)
		{
			int xdiff = xEvent.xbutton.x_root - start.x_root,
			ydiff = xEvent.xbutton.y_root - start.y_root;
			
			XMoveResizeWindow(display0, start.subwindow,
				winAttributes.x + (start.button==1 ? xdiff : 0),
				winAttributes.y + (start.button==1 ? ydiff : 0),
				Max(1, winAttributes.width + (start.button == 3 ? xdiff : 0)),
				Max(1, winAttributes.height + (start.button == 3 ? ydiff : 0)));
		}
		else if(xEvent.type == EventType.ButtonRelease)
			start.subwindow = None;
	}
}

int Max(int a, int b)
{
	return (a > b ? a : b);
}

Jen problikne a konec. Smím vědět proč? :)

Děkuji.
