Is there no "placeholder" text property for TextField()?

Heya,
I was trying to add "placeholder" text to a TextField but I don't see anything by that name. Is it named something else and I am just not seeing it or does it really not exist? I saw "usageHint" and thought perhaps that might be it, but after reading the description of it, probably not.

I imagine that in the meantime I could probably hack one together using events and adjusting the font color, but I feel that I really shouldn't have to do that. Hopefully, this will be added?

Thanks,
-MH

 

I understand. I appreciate the reply. I would, though, like to request that one day this be considered to be added if possible.

 

Awesome, good deal. I appreciate it.

 

I have completed this implementation, if you need to contact 771383629@qq.com

 

I appreciate it, but I already got it worked out.

Here's my implementation:

Code (CSharp):

1. public static void SetPlaceholderText(this TextField textField, string placeholder)
2. {
3.     string placeholderClass = TextField.ussClassName + "__placeholder";
4.  
5.     onFocusOut();
6.     textField.RegisterCallback<FocusInEvent>(evt => onFocusIn());
7.     textField.RegisterCallback<FocusOutEvent>(evt => onFocusOut());
8.  
9.     void onFocusIn()
10.     {
11.         if (textField.ClassListContains(placeholderClass))
12.         {
13.             textField.value = string.Empty;
14.             textField.RemoveFromClassList(placeholderClass);
15.         }
16.     }
17.  
18.     void onFocusOut()
19.     {
20.         if (string.IsNullOrEmpty(textField.text))
21.         {
22.             textField.SetValueWithoutNotify(placeholder);
23.             textField.AddToClassList(placeholderClass);
24.         }
25.     }
26. }

Usage:

Code (CSharp):

1. myTextField.SetPlaceholderText("Placeholder text");

You can also customize its appearance in USS:

Code (CSharp):

1. .unity-text-field__placeholder > .unity-base-text-field__input {
2.     color: #969696
3. }

 

Looks good, mind sharing?

 

Chances are good that if you do a search through your Unity package cache, you will come across an implementation that gets included a lot from different teams called "BetterTextField", that is what I have been using ever since I discovered it.

Example:
https://github.com/needle-mirror/co...9241ef4b/Editor/Components/BetterTextField.cs

 

The placeholder is really an useful feature.

Code (CSharp):

1.  
2. // Hopefully these features will eventually be in the default TextField eventually.
3. internal class BetterTextField : TextField
4. {
5. }
6.  

'Hopefully these features will eventually be in the default TextField eventually.' When it come true?

 

here I found an example:
https://docs.unity3d.com/Manual/UIE-Focus-Events.html

 

Try this:

Code (CSharp):

1. public string inputContent = "";
2. public string placeholder = "Text here...";
3. private void OnGUI() {
4.     // Draw TextArea
5.     inputContent = EditorGUILayout.TextArea(inputContent, GUILayout.ExpandWidth(true), GUILayout.ExpandHeight(true));
6.     // Draw Plcaeholder
7.     if (string.IsNullOrEmpty(inputContent)) {
8.         Rect pos = new Rect(GUILayoutUtility.GetLastRect());
9.         GUIStyle style = new GUIStyle
10.         {
11.             alignment = TextAnchor.UpperLeft,
12.             padding = new RectOffset(3, 0, 2, 0),
13.             fontStyle = FontStyle.Italic,
14.             normal =
15.             {
16.                 textColor = Color.grey
17.             }
18.         };
19.         EditorGUI.LabelField(pos, placeholder, style);
20.     }
21. }

It looks like:
