Creating a "drop zone" for textures
Hi,
I would like to create a drag and drop zone to get some textures, something like this Picture:
On EditorWindow class, I have put a rect and I've attempted to create a drop zone, but without success.
var dropZone = new Rect(10, 10, position.width - 10, 300);
var primaryColor = GUI.color;
if (Event.current.type == EventType.Repaint)
{
var style = new GUIStyle();
GUI.color = Color.white;
style.Draw(dropZone, new GUIContent("DropZone"),0);
GUI.color = primaryColor;
}
The text "DropZone" shows up, however the colored zone doesn't work. Any advice will be very helpful. Thanks!
I FOUND a similar solution right on this thread. However I would like to know more ways to accomplish it. I have changed my code and so far it works well. I would like a more "stylized" drop zone even this one can fit it as well.
Now:
My current code to handle that:
public static object[] DropZone(string title, int w, int h)
{
GUILayout.Box(title, GUILayout.Width(w), GUILayout.Height(h));
var eventType = Event.current.type;
bool isAccepted = false;
if (eventType == EventType.DragUpdated || eventType == EventType.DragPerform)
{
DragAndDrop.visualMode = DragAndDropVisualMode.Copy;
if (eventType == EventType.dragPerform)
{
DragAndDrop.AcceptDrag();
isAccepted = true;
}
Event.current.Use();
}
return isAccepted ? DragAndDrop.objectReferences : null;
}
OnGUI() method we call this new method and check if dropped file is actually a texture.
var objs = DropZone("Drop Textures Here", 300, 200);
if (objs != null)
{
foreach (var o in objs)
{
if (o is Texture2D)
Debug.Log("Obj: " + o);
}
}
Please, if you have some interesting information, share with us on this thread. I'll appreciate that.
Next step is somehow render all added textures with its name and its position. I need to handle an array with sub-window, how can I accomplish that??
