Hello

Could someone provide an example how to use addProtocolCommand?

The following is how I would expect it to work:

import tkd.tkdapplication;   // Import Tkd.

class Application : TkdApplication                       // Extend TkdApplication.
{

    private void exitCommand(CommandArgs args)           // Create a callback.
    {
         this.exit();                                     // Exit the application.
    }

    private void saveMeCommand(CommandArgs args)
    {
        new MessageDialog(this.mainWindow,"Saving...")
            .setMessage("Bye")
            .show();
    }

    override protected void initInterface()              // Initialise user interface.
    {

        this.mainWindow.addProtocolCommand(WindowProtocol.saveYourself, &this.saveMeCommand);

        auto frame = new Frame(2, ReliefStyle.groove)    // Create a frame.
            .pack(10);                                   // Place the frame.

        auto label = new Label(frame, "Hello World!")    // Create a label.
            .pack(10);                                   // Place the label.

        auto exitButton = new Button(frame, "Exit")      // Create a button.
            .setCommand(&this.exitCommand)               // Use the callback.
            .underlineChar(1)
            .pack(10);                                   // Place the button.

    }

}

void main(string[] args)
{
    auto app = new Application(); // Create the application.
    app.run();                                           // Run the application.
}


I get the following when I try to compile:

tkd\window\window.d(426): Error: undefined identifier CommandCallback
main.d(21): Error: template tkd.window.window.Window.addProtocolCommand cannot deduce function from argument types !()(WindowProtocol, void delegate(CommandArgs args)), candidates are: tkd\window\window.d(426):        tkd.window.window.Window.addProtocolCommand(this T)(string protocol, CommandCallback callback)

If I comment out the line where I try to add the command, it compiles and runs fine:

Hopefully better formatting of code here:

import tkd.tkdapplication;

class Application : TkdApplication
{

    private void exitCommand(CommandArgs args)
    {
         this.exit();
    }

    private void saveMeCommand(CommandArgs args)
    {
        new MessageDialog(this.mainWindow,"Saving...")
            .setMessage("Bye")
            .show();
    }

    override protected void initInterface()
    {
        this.mainWindow.addProtocolCommand(WindowProtocol.saveYourself, &this.saveMeCommand);

        auto frame = new Frame(2, ReliefStyle.groove)
             .pack(10);

        auto label = new Label(frame, "Hello World!")
            .pack(10);

        auto exitButton = new Button(frame, "Exit")
            .setCommand(&this.exitCommand)
            .underlineChar(1)
            .pack(10);
    }

}

void main(string[] args)
{
    auto app = new Application();
    app.run();
}

I'm at work at the minute I'll take a look later on.

Added the missing import and now all works fine. Fixed in v1.0.5-beta. Any more issues open them up in github and i'll deal with them there. :)

Thanks Gary!
I was expecting it to catch when someone hits the close X on the title bar, but I changed it to this

this.mainWindow.addProtocolCommand(WindowProtocol.deleteWindow, &this.saveMeCommand);
		
And that seems to do the trick.

I will post bugs on github in future, I thought I was doing something wrong.
I have never messed with TCL/TK until now.

BTW, Really nice job on this!  Thanks for the quick reply and fix
