Hi all!
I've just started fiddling around with D, and i've only just downloaded DFL/Entice today. I am however having some bother with the click event on buttons (i've put a button on the form designer, and tried to add some code for the event handler, but i'm obviously doing it wrong, as it won't compile)

code is as follows :

Code:
 /*
   Generated by Entice Designer 0.7.2
   Entice Designer written by Christopher E. Miller
   www.dprogramming.com/entice.php

   This source code is public domain.
*/

private import dfl.all;


class MyTestForm: dfl.form.Form
{
   // Do not modify or move this block of variables.
   //~Entice Designer variables begin here.
   dfl.button.Button button1;
   //~Entice Designer variables end here.
   
   
   this()
   {
      initializeMyTestForm();
      button1.click ~= &Button1Click;
   }
   
   
   private void initializeMyTestForm()
   {
      // Do not manually edit this block of code.
      //~Entice Designer 0.7.2 code begins here.
      //~DFL Form
      text = "My Test Form";
      clientSize = dfl.drawing.Size(136, 69);
      //~DFL dfl.button.Button=button1
      button1 = new dfl.button.Button();
      button1.name = "button1";
      button1.bounds = dfl.base.Rect(16, 16, 104, 32);
      button1.text = "Test Button";
      button1.parent = this;
      //~Entice Designer 0.7.2 code ends here.
   }
}


int main()
{
   int result = 0;
   
   try
   {
      // Application initialization code here.
      
      Application.run(new MyTestForm());
   }
   catch(Object o)
   {
      msgBox(o.toString(), "Fatal Error", MsgBoxButtons.OK, MsgBoxIcon.ERROR);
      
      result = 1;
   }
   
   return result;
}


void Button1Click(Object sender, EventArgs ea)
{
   //lblSquare.text  = txtInput.text;
   msgBox("test");
}


i get the error message as follows when i compile:

TestAF.d(23): function dfl.event.Event!().Event.opCatAssign (void delegate(Objec
t, EventArgs)) does not match argument types (void(*)(Object sender, EventArgs e
a))
TestAF.d(23): cannot implicitly convert expression (& Button1Click) of type void
(*)(Object sender, EventArgs ea) to void delegate(Object, EventArgs)


i've tried changing a few things about, but i'd be very grateful if someone could point out what i am doing wrong, and what the correct way is. I know that it's the "button1.click ~= &Button1Click;" line, if i comment it out, it compiles fine.

thanks in advance!

Oops! finally figured it out, i should have the event handler code inside the main form class. I've slapped myself soundly around the head for asking stupid questions!

Thanks anyway!
