Resizable empty window

For testing purposes i do need a window that should be resizable and when resized should print out the new dimensions, say on clicking the mouse.

I used 

  1. 	   tags[c].ti_Tag	 = WA_SizeGadget;
  2. 	   tags[c].ti_Data = TRUE;	++c;
  3. 	   tags[c].ti_Tag	 = WA_CloseGadget;
  4. 	   tags[c].ti_Data = TRUE;	++c;
  5. 	   tags[c].ti_Tag	 = WA_IDCMP; 
  6. 	   tags[c].ti_Data = IDCMP_CLOSEWINDOW | IDCMP_MOUSEBUTTONS | IDCMP_NEWSIZE ; ++c

and the ReplyMsg code looks like

  1. BOOL handleIDCMP(struct Window *win, BOOL done)
  2. {
  3. struct IntuiMessage *message;
  4. USHORT code;
  5. SHORT mousex, mousey;
  6. ULONG class;
  7.  
  8.  
  9. while (NULL != (message = (struct IntuiMessage *)GetMsg(win->UserPort)))
  10.     {
  11.  
  12.     class  = message->Class;
  13.     code   = message->Code;
  14.     mousex = message->MouseX;
  15.     mousey = message->MouseY;
  16.  
  17.  
  18.     ReplyMsg((struct Message *)message);
  19.  
  20.     /* The class contains the IDCMP type of the message. */
  21.     switch (class)
  22.         {
  23.         case IDCMP_CLOSEWINDOW:
  24.             done = TRUE;
  25.             break;
  26.  
  27. 	case IDCMP_NEWSIZE:
  28.             break;
  29.         case IDCMP_MOUSEBUTTONS:
  30.             switch (code)
  31.                 {
  32.                 case SELECTUP:
  33. 		    getdimensions();
  34.                     break;
  35.  
  36.                 default:
  37.                     printf("UNKNOWN CODE\n");
  38.                     break;
  39.                 }
  40.             break;
  41.         default:
  42.             printf("Unknown IDCMP message\n");
  43.             break;
  44.         }
  45.     }
  46. return(done);
  47. }

The window opens, has a size gadget indeed, but i can't resize it ???
Using the mouse i do get the wanted output. I can close it.

You need to set WA_MinWidth,

You need to set WA_MinWidth, WA_MinHeight, WA_MaxWidth and WA_MaxHeight, too. They all default to WA_Width resp. WA_Height leaving you with a non-movable size gadget.

And you don't get IDCMP_MOUSEBUTTON messges when you click on a GUI object. You should put getdimensions() into the IDCMP_NEWSIZE section. IDCMP_MOUSEBUTTON messages are only received it no other GUI element takes them.

Thanks a lot Thomas.

As a matter of fact i don't want to have the size info during the resize but after.

Gui4Cli allows you with Ctl_W to 'note' the size of a resized gui, and use this afterwards as minimum or maximum size. The results are not the same as the on you get with just opening a window at these sizes. I just want to investigate where this discrepancy has its origun from.

Interesting use of tags

Interesting use of tags there. Don't forget to put a TAG_END on the end of your taglist. :-)
