Double click in GUI

I'm currently trying to create a window to display a directory and allow the user to select a location to save a file. There doesn't seem to be a GUI control for this so I'm using a series of labels and the scrollview to create a list box. On top of each label, I've placed a toggle button so I can capture a mouse click over a label and highlight that label. Now I'm trying to capture a double click on a toggle button. Is there a way to do capture double clicks? or does anyone have a better solution for a directory dialog box. Thanks all.

 

heres some converted code that i use in my project... i've removed some parts to make it more readable... but may have broken it in the process

Code (csharp):

1.  void OnMouseDown()
2.     {
3.         if (intClickCount == 0)
4.         {
5.             intClickCount++;
6.             StartCoroutine("mCheckMouseClick");
7.         }
8.         else
9.         {
10.             intClickCount++;
11.         }
12.     }
13.     IEnumerator mCheckMouseClick()
14.     {
15.         if (intClickCount == 1)
16.         {
17.             yield return new WaitForSeconds(0.4f); //This sets the delay for the double click validation
18.             if (intClickCount > 1)
19.             {
20.                 //Debug.Log("Double Clicked");
21.                 intClickCount = 0;
22. //Do double click stuff here
23.             }
24.             else
25.             {
26.                 //Debug.Log("Single Clicked");
27.                 intClickCount = 0;
28.             }
29.         }
30.     }

 

What we did in the terrain inspector was to use Event.current.clickCount.

Something like this:

Code (csharp):

1.  
2. if (GUI.Button (Rect (10,10,100,20), "DoubleClick me"))  Event.current.clickCount == 2) {
3.    // This button was doubleclicked within the time specified in the user's system prefs for  double clicking
4. }
5.  

 

I dont know if this is of use -it may be to beginners-but I went over Shauns and tidied it up. Works fine in 1.6.2. Thanks Shaun, very helpful. This is a javascript:

Code (csharp):

1. private var intClickCount=0;
2. function OnMouseDown()
3.     {
4.         if (intClickCount == 0)
5.         {
6.             intClickCount++;
7.             StartCoroutine("mCheckMouseClick");
8.         }
9.         else
10.         {
11.             intClickCount++;
12.         }
13.     }
14.     function mCheckMouseClick()
15.     {
16.         if (intClickCount == 1)
17.         {
18.             yield WaitForSeconds(0.4); //This sets the delay for the double click validation
19.             if (intClickCount > 1)
20.             {
21.                 Debug.Log("Double Clicked");
22.                 intClickCount = 0;
23. //Do double click stuff here
24.             }
25.             else
26.             {
27.                 Debug.Log("Single Clicked");
28.                 intClickCount = 0;
29.             }
30.         }
31.     }

Wow!! Thank you Unity gurus!! I will try all these out. I'm sure one of them will fit my needs perfectly.

 

I tried using Event.current.clickCount and it works great when I publish for the mac, but it doesn't seem to work when publishing for the pc. Could this be a bug?

As for the OnMouseDown solution, will it work with the built-in GUI system? From what I've read in the docs, it only works for GUIElements. If so, I guess I'd need to attach the script to a GUIText or GUITexture object.

Anyhow, just an update to people know if these worked out.

 

This was why I wrote my own click handler routine - I tried a few times but couldnt get clickcount working - i thought it was just me

 

In these cases, please file bugs. I'll look into making sure it's in the next release.
