Display Screen Info

[arenner]

Hello. I can't seem to find anything about the "Display Screen Info" function in the SDK. I found the "screen_info_type" struct, but none of the options turns the screen axes on. I think the default is the F9 key. I just want to turn these axes on in the same way the F9 key does, but in a chook.

There is an exported, but non-documented variable controlling that state which is ...

 

DllExport MC_BYTE show_part_info = 0; /* 0=none, 1=F9, 2 = AltF9, 3 = both */

 

Add the above line to your code and then you can set this variable and force a repaint to see the screen update.

 

Or....

 

You can use...

 

post_FT_command ("Mastercam", "OnVPAxesToggle");

 

this will toggle the state just like F9 does.

I tried "show_part_info = 1" but that did not work for me. I also made sure to repaint and rebuild graphics at the end of my chook.

I tried this in my chook.

 

code:

---

 

extern DllImpExp MC_BOOL vp_axes;

extern "C" __declspec(dllexport) int m_main (int not_used)

{

if(vp_axes)

{

post_FT_command ("Mastercam","OnVPAxesToggle");

}

return MC_NOERROR|MC_UNLOADAPP;

}

I copied in your code, but I must still be doing something stupid:(

arggg..

post_FT_command ("Mastercam","OnDisplayInfo");

edit:

extern DllImpExp MC_BYTE show_part_info;

I'm sure these lines of code work, I'm also just sure that I don't understand how this code works.

 

First, I copy the line:

 

extern DllImpExp MC_BYTE show_part_info;

 

somewhere above my m_main function. Then inside main I copied in this code:

 

post_FT_command ("Mastercam","OnDisplayInfo");

 

If I need to do more than that, I'm a newbie so forgive my ignorance. If I don't need to do anything else then it's not working. I have included these at the end of m_main:

 

repaint_graphics();

rebuild_graphics();

return MC_NOERROR|MC_UNLOADAPP;

[Takashi Sato from Ai Solutions.]

you have to use DllImpExp, because..

 

//this is for exporting the function from your chook dll

DllExport MC_BYTE show_part_info = 0;

//use the exported function from external dll or exe...

DllImpExp MC_BYTE show_part_info;

 

 

code:

---

if(show_part_info)

{

show_part_info=0;

//you have to repaint

repaint_graphics();

}

 

or,,

if(show_part_info)

{

post_FT_command ("Mastercam","OnDisplayInfo");

//Run a Message Pump if you need it immidialtely...

 

}

In addition to what Takashi says, for pumping mechanism, the following code snippet should work

code:

---

BOOL PumpMessages( )

{

MSG msg;

//

// Retrieve and dispatch any waiting messages.

//

while (::PeekMessage (&msg, NULL, 0, 0, PM_NOREMOVE))

{

if (!AfxGetApp()->PumpMessage ())

{

::PostQuitMessage (0);

return FALSE;

}

 

}// end of while (::PeekMessage (&msg, NULL, 0, 0, PM_NOREMOVE))

 

 

// Framework's idle processing mechanism.

LONG lIdle = 0;

while (AfxGetApp()->OnIdle (lIdle++));

 

return TRUE;

}

---

Happy coding!

Thanks for your help, but nothin's working. I am not going to try to get this function to work. Thanks a bunch for all your help though guys:)
