Description

Description:

Find display by its IDD (which is defined in the description.ext or config).
If the specified display can't be found displayNull ("No display") is returned, (which can be tested with the isNull command).

⚠

Dedicated servers and headless clients don't have a primary display (e.g findDisplay 46 will return displayNull).
You can detect both with the hasInterface command.

A list of common displays can be found in the notes below; for a full list, see findDisplay/Arma 3 IDD list..

findDisplay does not find displays defined under RscTitles (even when they are visible).
To access those types of displays, either assign the resource to a global variable, or pass its this value to a script, during the onLoad event: e.g.

class RscTitles {
  class MyRsc {
	 onLoad = "myDisplay = (_this select 0)"; // or
	 // onLoad = "_this execVM 'myDialog.sqf'";
	 ...

You can then use the stored value as you would for regular dialogs: (myDisplay displayCtrl 1111) ctrlSetText "hello there");

I posted a tutorial on finding and using displays here.

I have tested the behavior of this command and I found out that it [ findDisplay ] appears to only return the display AFTER any onLoad event handler of that display is done. So, using findDisplay inside an onLoad event handler is useless.

There are some specific cases, where findDisplay will not be able to find an existing display. Here's the cases and how to act on them:

// Your display has IDD= -1.
class RscDisplayNew
{
	idd = -1;
	scriptName = "RscDisplayNew";
	...
};

// Your display doesn't have IDD
class RscDisplayNew
{
	scriptName = "RscDisplayNew";
	...
};

// Your display doesn't have scriptname with IDD = -1
class RscDisplayNew
{
	idd = -1;
	...
};

// Your display doesn't have scriptname, neither IDD
class RscDisplayNew
{
	...
};

1. You actually can find a -1 display, but this means finding a display with this IDD might be a problem, when there are a few displays marked as -1.So as you can see, theres an entry called scriptName. You can get a reference to this display by using uiNamespace:(uiNamespace getVariable "RscDisplayNew")NOTE: Variables are overwritten with a reference of the last declared display under the same scriptName entry. Take a look at case 3 for solution.
2. Displays without IDD's can actually exist. They can be manipulated only in a way described in the first case using uiNamespace.
3. You can really have this display seeking it manually in a allDisplays return. This is experimental, but working option.
4. You will have a problem finding this display, since this display doesn't exist even in allDisplays(?) return. Behaviour unknown.
