[SOLVED] Handles not drawing on Button toggle.

Hey all, I'm hoping someone can help with a little issue I've ran into.

I've ran into a confusing issue with the Handles class, trying to draw a bezier line after a GUI Button has been clicked, has brought me no luck.

Drawing it outside of the GUI.Button, and all is glorious.

The code currently used to display the curve.

Code (CSharp):

1.     void DrawCurve(Rect start, Rect end) {
2.                 Vector3 startPos = new Vector3(start.x + start.width, start.y + start.height / 2, 0);
3.                 Vector3 endPos = new Vector3(end.x, end.y + end.height / 2, 0);
4.                 Vector3 startTan = startPos + Vector3.right * 50;
5.                 Vector3 endTan = endPos + Vector3.left * 50;
6.                 Color shadowCol = new Color(0, 0, 0, 0.06f);
7.                 for (int i = 0; i < 3; i++) // Draw a shadow
8.                     Handles.DrawBezier(startPos, endPos, startTan, endTan, shadowCol, null, (i + 1) * 5);
9.                 Handles.DrawBezier(startPos, endPos, startTan, endTan, Color.black, null, 1);
10.             }

Calling the code likes this from a Method inside OnGUI.

Code (CSharp):

1.     // DRAW START NODE
2.                 Rect startPage = new Rect(10, 45, 100, 50);
3.                 Rect inputRect = new Rect(startPage.width - 16, startPage.y + 5, 16, 16);
4.                 _uiStyle = EditorUI.ui.GetStyle("box_opaque");
5.                 GUI.Box(startPage, string.Empty, _uiStyle);
6.  
7.                 GUI.Label(new Rect(startPage.x + 5, startPage.y + 5, startPage.width, 20), "START", EditorStyles.miniBoldLabel);
8.                 _uiStyle = EditorUI.ui.GetStyle("connector_empty");
9.                 if (GUI.Button(inputRect, string.Empty, _uiStyle)) {
10.                     DrawCurve(inputRect, new Rect(100, 100, 10, 10));
11.                 }

I was originally trying to get it to display a line from the input Rect, to the mouse until another Rect has been selected, but that's a problem for another day.

Thanks in advance!

 

GUI.Button is only true for the single frame that the button is pressed, so your DrawCurve is only called once

 

So, what do you think would be a suitable substitute? GUI.Toggle?

EDIT:
GUI.Toggle seems to be the approach for this, thanks for the helping hand.
