Window manipulation in unity

Jake12456 · Apr 3, 2011

I am working in a CAVE system in unity3D. I have 4 windows networked together in order to manage the system. I am trying to make the windows on start up auto-place themselves on separate monitors in order to create the CAVE experience. To do this I need to have the windows begin or update with a set position to place them on different desktops on a multi-screened setup, and to have them be non full-screen and the windows not decorated. Is this possible in Unity or should I start looking into incorporating the winAPI?

Would need WinAPI if you want to position the window.
Should not be hard though

So I tried using winAPI and am having an issue. I am grabbing the current running process, grabbing a handle to the window, and then attempting to move it. However the handle I am getting is empty. Also when I check on any window data its null. I am however getting the process name and ID of my program so I know I AM getting the correct process. Does unity keep this info locked down? Here is my code if anyone can help.

using UnityEngine;
using System.Collections;
using System.Runtime.InteropServices;
using System;
using System.Diagnostics;

public class windowMod : MonoBehaviour {
[DllImport("user32.dll")]
static extern bool SetWindowPos(IntPtr hWnd, int hWndInsertAfter, int X, int Y, int cx, int cy, uint uFlags);
string word;
Process p;
// Use this for initialization
void Start () {
const uint SWP_NOMOVE = 0X2;
const uint SWP_NOSIZE = 1;
const uint SWP_NOZORDER = 0X4;
const uint SWP_SHOWWINDOW = 0x0040;
p = Process.GetCurrentProcess();
word = p.MainWindowTitle;
bool a = SetWindowPos(p.MainWindowHandle,0,10,10,1024,786,SWP_NOMOVE|SWP_NOSIZE);
}
void OnGUI(){
GUI.Label(new Rect(10, 10, 200, 100), word);
}
// Update is called once per frame
void Update () {

}
}

Ok got it. unity must do something in the background that doesn't coorelate the window handle to the process ID 1 to 1. I grabbed the forground window instead and it worked. heres the fix

using UnityEngine;
using System.Collections;
using System.Runtime.InteropServices;
using System;
using System.Diagnostics;

public class windowMod : MonoBehaviour {
[DllImport("user32.dll")]
static extern bool SetWindowPos(IntPtr hWnd, int hWndInsertAfter, int X, int Y, int cx, int cy, uint uFlags);
[DllImport("user32.dll")]
static extern IntPtr GetForegroundWindow();
// HWND WINAPI GetForegroundWindow(void);
string word;
// Use this for initialization
void Start () {
const uint SWP_NOMOVE = 0X2;
const uint SWP_NOSIZE = 1;
const uint SWP_NOZORDER = 0X4;
const uint SWP_SHOWWINDOW = 0x0040;
const uint SWP_HIDEWINDOW = 0x0080;
word = GetForegroundWindow().ToString();
bool a = SetWindowPos(GetForegroundWindow(),0,0,0,1024,786,SWP_NOZORDER | SWP_NOSIZE | SWP_SHOWWINDOW);
}
void OnGUI(){
GUI.Label(new Rect(10, 10, 200, 100), word);
}
// Update is called once per frame
void Update () {

}
}

I can see this being handy for a lot of people. Could you put it on the wiki?

Sorry for the late reply. If I get time I guess I'll post it. Feel free to post it if you want to.
