Re: [Plib-users] R: Problem with a PUI-Win32-Native

[John F. F. <joh...@cy...>]

The calls to "puMouse" on lines 133 and 140 have a first argument of one; 
which is defined (see pu.h, line 37) to be the middle mouse button.  The 
active mouse button for the menu defaults to the left mouse button, which 
has a value of zero.  The "WM_LBUTTONDOWN" and "WM_LBUTTONUP" blocks should 
call "puMouse ( PU_LEFT_BUTTON, ...".  Here is what the section of code 
will look like if all three buttons are supported:

	case WM_LBUTTONDOWN:
		oldMousePos.x = currentMousePos.x = LOWORD (lParam);
		oldMousePos.y = currentMousePos.y = HIWORD (lParam);
		if( puMouse ( PU_LEFT_BUTTON, PU_DOWN, currentMousePos.x, 
currentMousePos.y ))
		{ }//MessageBox(NULL,"DOWN","down",MB_OK); }
		break;

	case WM_LBUTTONUP:
		currentMousePos.x = LOWORD (lParam);
		currentMousePos.y = HIWORD (lParam);
		if( puMouse ( PU_LEFT_BUTTON, PU_UP, currentMousePos.x, currentMousePos.y 
))
		{}// MessageBox(NULL,"UP","UP",MB_OK); }
		break;

	case WM_MBUTTONDOWN:
		oldMousePos.x = currentMousePos.x = LOWORD (lParam);
		oldMousePos.y = currentMousePos.y = HIWORD (lParam);
		if( puMouse ( PU_MIDDLE_BUTTON, PU_DOWN, currentMousePos.x, 
currentMousePos.y ))
		{ }//MessageBox(NULL,"DOWN","down",MB_OK); }
		break;

	case WM_MBUTTONUP:
		currentMousePos.x = LOWORD (lParam);
		currentMousePos.y = HIWORD (lParam);
		if( puMouse ( PU_MIDDLE_BUTTON, PU_UP, currentMousePos.x, 
currentMousePos.y ))
		{}// MessageBox(NULL,"UP","UP",MB_OK); }
		break;

	case WM_RBUTTONDOWN:
		oldMousePos.x = currentMousePos.x = LOWORD (lParam);
		oldMousePos.y = currentMousePos.y = HIWORD (lParam);
		if( puMouse ( PU_RIGHT_BUTTON, PU_DOWN, currentMousePos.x, 
currentMousePos.y ))
		{ }//MessageBox(NULL,"DOWN","down",MB_OK); }
		break;

	case WM_RBUTTONUP:
		currentMousePos.x = LOWORD (lParam);
		currentMousePos.y = HIWORD (lParam);
		if( puMouse ( PU_RIGHT_BUTTON, PU_UP, currentMousePos.x, 
currentMousePos.y ))
		{}// MessageBox(NULL,"UP","UP",MB_OK); }
		break;

The button box appears not to have a callback defined.

Thanks. You are right. The line was twice commented. However this boolean
controled only the activation of the later drawn triangle manipulator.
I discarded the calls to the gl drawings and manipulation in the following 
code
(below), keeping only PUI renderings. The problem remains : the PUI display
correcly, yet no callbacks.

I'm wondering about this warning in the documentation :

"[...] #define PU_USE_NATIVE before you include pu.h - and PUI will try to
figure out what it needs to know using native commands such as those in the
wgl/glX/agl library - in the absence of a windowing library. This may 
result in
"some problems" if you want to do "certain operations" for which PUI needs 
to
query the windowing library. Use of PU_USE_NATIVE is not recommended in 
systems
that allow you to resize the window or open multiple windows."
