Can't get basic code to work

Hello,

Sorry if this seems a bit idiotic guys but I can't even get
through the 
basic stuff.

Using MonoDevelop/Stetic, I just have a basic window with a
button, 
label and entry widgets. I have the following attached to
the button 
buttonPressEvent:

    protected virtual void onButtonPress (object o, 
Gtk.ButtonPressEventArgs args)
    {
        label1.Text = "abcd";
        entry1.Text = "1234";
    }

and this attached to the button Activated signal:

    protected virtual void onActivated (object sender,
System.EventArgs e)
    {
        label1.Text = "abcd";
        entry1.Text = "1234";
    }

When I run the app and click on the button, neither one of
these is 
working, the text does not show up in the label or the entry
box. What 
am I missing?


Thanks,
George

you probably want button.Clicked event, not Activated

Looks like the compiler is not aware of the Clicked Signal
and/or the Label & 
Entry widgets. Try the following:

1.- On Stetic you need to initialize the Clicked signal for
the button1. On 
the Stetic designer, select the button on the <Widget
Properties> go to the 
tab <Signals> (There are only two tabs,
<Properties> & <Signals>).  Expand 
<Button Signals> and then select <Clicked>, then
double click to initialize 
the Signal, and again double click to create the template:

protected virtual void OnButton1Clicked(object sender,
System.EventArgs e){ }

On MainWindow.cs in the view Source Code (MainWindow.cs have
two view <Source 
Code> & <Designer>). Here you can start coding.

2.- Probably you are not declaring the label1 & entry1
widgets. So you need to 
declare them as Gtk widgets right after the declaration of
the public class 
and before the constructor:

public class MainWindow: Gtk.Window
{       
        Label label1; // or Gtk.Label 
        Entry entry1; // or Gtk.Entry
        public MainWindow (): base ("")
        {

By the way, probably you want to try this so you clearly
understand the order 
the events/signal occurs:

        protected virtual void OnButton1Clicked(object
sender, 
System.EventArgs e){
                label1.Text = "Clicked";
                entry1.Text = "Clicked";}

        protected virtual void OnButton1Activated(object
sender, 
System.EventArgs e){
                label1.Text = "Activated";
                entry1.Text = "Activated";}

        protected virtual void OnButton1Entered(object
sender, 
System.EventArgs e){
                label1.Text = "Entered";
                entry1.Text = "Entered";}

        protected virtual void OnButton1Pressed(object
sender, 
System.EventArgs e){
                label1.Text = "Pressed";
                entry1.Text = "Pressed";}

        protected virtual void OnButton1Released(object
sender, 
System.EventArgs e){
                label1.Text = "Released";
                entry1.Text = "Released";}

        protected virtual void OnButton1Left(object sender,
System.EventArgs 
e){
                label1.Text = "Left";
                entry1.Text = "Left";}

And don't forget to initialice the all the signals on
Stetic.

Looks like the problem was with using the right signal.
Using the 
Clicked event and my original steps is working now. One
thing that I was 
doing which is different from the steps that you outline is
that I was 
entering the event name manually in the signals column (the
fields do 
say to "Click here to add a new handler") as
opposed to double clicking 
twice on the signal name itself, but this does not appear to
make a 
difference, it is the Clicked signal that was needed. I do
prefer the 
double click approach thou, so thank you for pointing that
out.


Thank you for your help,
George

Good suggestion.  As luck would have it, the two that I
chose 
(ButtonPressEvent and Activated) don't seem to do much.

One signal/event which I'm trying to find is the equivalent
of the 
delphi form onCreate event (when a window is created). Would
this be the 
"Realized" signal ? I would need this to put
one-time run start-up code 
into.


Thank you,
George

Would you mean inside of the "public partial class
MainWindow: 
Gtk.Window" block in MainWindow.cs ?

Yes.  Within that block (ie, within the class), you want to
add a
constructor.  If this term is new to you you'll want to find
a book or
tutorial on C#, but basically it's a method called when your
class
(your window in this case) is first created, and it usually
looks like
this:

public MainWindow ()
{
   // Do initialization stuff here
}

Hope this helps,
Sandy

If that code will take a long time to be executed you can
start it in
a thread, and after the tread ends, update the controls (you
can't
update from another thread).

If the time it needs is small, you can just do it in the
constructor,
even before the window is shown, or first forcing it to show
and then
running the piece of code. It is important to know that if
the code
depends on the existence of the controls, it should be
called after
the code Stetic generates is called.

Fun,
