Why to the Execute ? In the execute() you open the dialog. If you have a button in your dialog, you must write what should be done when pressing the button in the command(id,msg).

  
MyDialog::Command(id,msg) {   
    if (id == MY_BUTTON) { // Constant defined in c4d_symbols.h, will be created with ResEdit automatically   
        TextDialog("You pressed the button");

Thanks,

Ok but if I want something to happen only if a certain checkbox was ticked when we close the dialog ?

For example I cannot use doc->GetFirstObject() in the Command(id,msg) method... how could my "whole" code reside in this method ?

Hoping it's understandable ...

Oh, of course you can.
Btw, depending on what you're doing its more comfortable to use global variables for all parts in your dialog.

  
var mod_pos, mod_ang, mod_sca;  
  
/// Dialog definitions etc ..  
  
MyDialog::Command(id,msg) {  
  mod_pos = GetCheckbox(CHK_MOD_POS);  
  mod_ang = GetCheckbox(CHK_MOD_POS);  
  mod_sca = GetCheckbox(CHK_MOD_POS);  
  
  
  
  if (id == MY_BUTTON) {      
      var doc = GetActiveDocument();  
      var op = doc->GetActiveObject();  
      if (!op) { return False; }  
  
      doc->AddUndo(UNDO_CHANGE,op);        //R12 Constant  
      if (mod_pos == true) { op->SetPosition(vector(100)); }  
      if (mod_ang == true) { op->SetRotation(vector(1.23)); }  
      if (mod_sca == true) { op->SetScale(vector(1.3)); }  
  }  
}

You can use the Get/Set methods of the GebaseDialog class. So after closing the dialog you can read out the values.

  
MyMenuPlugin::Execute(doc)  
{  
  d->Open(FALSE,-1,-1);  
    
  if (d->GetCheckbox(MY_CHECKBOX))  
  {  
      //do something  
  }  
  else  
  {  
      //do something  
  }  
}

Please avoid global variables as much as possible.

This is one of those things that needs to be better documented.
There's several ways to create a plugin's structure. And they will all work. But there seems to be a certain preferred method to the madness.

What I've gathered from poking around is this:

-Init() function should only be used to set initial values
-Message() function should only be used to issue updates when something changes
-Command() function should only be used to hold GUI state code
-Execute() function is not just for opening dialogs. But also for where your main code should be placed

But then I sometimes see people put their main code inside of the main() section for dialog related scripts and plugins. Where most people just place the dialog window code.

I'd love to see an official "Maxon's preffered method for plugin structures" in the future.
right now it seems like the wild, wild, west. With everyone adding their own little twist on the plugin structures the create. And that's all very confusing to understand when you're newbie like me.

But isn't it more efficient than use GetCheckbox() etc.. more than one time ?
They actually don't have to be global if you don't need them anywhere else, but at least for the hole Command() function if you need them more than one time.

I've assumed a async-dialog.

In fact this is not an async dialog.

So with the GetCheckbox() I can get a value from a closed dialog ?

Unfortunately I hadn't time to test it tonight, but there are some answers that will really help me.

I also agree that it would be very nice to have a kind of "map" from maxon explaining where and why it is better to put the main code.

Thanks all !

Yes, the data is stored in the object even if the dialog is closed.

I agree, too, would be very nice.

Hi again !

When I call back a Checkbox (once the dialog is closed) it always returns 0, even if it was ticked.

I'm using dialog->GetCheckbox(ID)

Any idea ?

By the way, using indentation and posting the code in a [\\\code] [\\/code] Block (without \\\) would
make it much more readable.

//
You've obviosly derived your dialog class from GeDialog. Otherwise 'dialog->Open(FALSE,-1,-1)' would raise an error.
There is an additional subclass for modal dialogs. (GeModalDialog)
But I can't imagine this is the reason for the problem.

The title is set in Init(). Do never forget return values for overloaded functions, even they're blank. (For eg Init())
But couldn't figure out the real problem yet.

I'm still a learner with this plugin stuff. So take this advice with a grain of salt.
If you're wanting to get the state of the checkbox when you close the dialog window with the "OK" button. Then give this a try:

  switch (id)   
    {  
    case BUT_CANCEL:  
          Close();   
          break;  
  
    case B_OK:   
       if(dialog->GetCheckbox(P_PATH))  
         {  
          println("ON");  
         }   
       else{  
           println("Off");  
          }       
         Close();

I've been told that switches are supposed to be used in place of if statements. And putting if's inside of switches is wrong.
However, sometimes it's necessary to use nested if statements to do things. So in this case it makes sense to me to use them together.
As I said...I'm still learning. So take this advice as something coming from a learner.

Is that even possible to do with a dialog?
ASFAIK. Once a dialog closes. Everything in it is deleted from memory and can't be accessed until the dialog is opened again.

My understanding is the only way to store things is by using a tag plugin. Since the tag is always there. It can be used to hold a value(in this case a state value). And you can even make tag's invisible to use them as hidden storage containers.
But I could be wrong.....
