How do we create and display a PANEL in C++?

We tried different approaches, for example this one:

Code:

---

PANEL* menu = pan_create(NULL, _VAR(100));
    menu->flags |= VISIBLE;
    menu->alpha = _VAR(100);
    menu->size_x = _VAR(10);
    menu->size_y = _VAR(10);
    menu->red = _VAR(100);
    menu->pos_x = _VAR(200);
    menu->pos_y = _VAR(200);

---

The pan_create function does return a valid pointer (not null), but no matter what we try, we don't get that panel to display...

Thanks for all help or sample code!
Jonas & his desperate team ;-)

delphi example but should give you the idea-- you need to pass the parameters in a string--make sure you put the ";" at the end!

Code:

---

Panel2 := pan_create('bmap = levelcode3.pcx;pos_x = 325;
          pos_y = 105;flags=visible;
          button=15,20,ThumbNail3.pcx,ThumbNail3.pcx,ThumbNail3.pcx,
          Null,Null,Null;',
          _VAR(1));

---

try menu->flags |= _VAR(VISIBLE);

Your guys are heroes... thanks a lot ;-)

It works with LazyDog's pan_create approach. However, for the flags, it seems that using _VAR() is wrong !?

Cheers,

One more question:

what about buttons and sliders: Is there a way for a pure C++ app to use them?
- I don't see how I should pass a pointer to a function to them
- For sliders, I don't see how I could read the value

LazyDog, you seem to be using a button... if I tried this code, but it wouldn't display. Did you really get this work?

Thanks for all help

_VAR() is the delphi function I think for c++ it's just VAR(), Var is a reserved word in delphi so I had to dd a character.

yes you can use buttons and sliders in c++ and yes my code works perfectly in delphi.

here are some delphi examples, read the help file for info about
pan_create, pan_setevent so you can convert to c++

Code:

---

Var ThePos : Var_;               // tracks value of our vslider

//create a vslider
//don't forget the ";" at the end of the command string !!!!
//we'll use pan_setver to use our variable ThePos for the value of the slider
Panel1 := pan_create('bmap = VScrollBox3.pcx;pos_x = 550;pos_y = 230;
          vslider=1,1,230,ThumbNail3.pcx,1,100,0;',_VAR(1));

FlagOn(Panel1.flags,_VISIBLE or OVERLAY);     // FlagOn is delphi fucntion
pan_setvar(Panel1,_VAR(4),_VAR(1.7),@ThePos);

// this example creates a button and assigns delphi functions to the events
Panel2 := pan_create('bmap = levelcode3.pcx;pos_x = 325;pos_y = 105;
          flags=visible;button=15,20,
          ThumbNail3.pcx,ThumbNail3.pcx,ThumbNail3.pcx,
          Null,Null,Null;',_VAR(1));

FlagOn(panel2.flags,_VISIBLE or OVERLAY);
Panel2.event := @PanelClickEvent;
pan_setevent(Panel2,_VAR(3),_VAR(1),@ScrollBtnClicked);
pan_setevent(Panel2,_VAR(3),_VAR(1.1),@MouseLeaveEvent);
pan_setevent(Panel2,_VAR(3),_VAR(1.2),@MouseOverEvent);

pan_setevent is not documented in the 3D GameStudio Manual. Is is also not defined in the header files (.h) provided by the SDK.

I am using A6.

In my A7-headers pan_setevent is declared in afuncs.h ... Did u look within this file?

BTW. its also _VAR(x) for the conversation int/double to var in C++

Yes it seems pan_setevent and pan_setvar are addition in A7 that are not present in A6, so I believe with A6 there's simply no way to use those buttons. Anyway thanks for all your help! Finally we ended up coding those buttons by ourselves...

Thanks a lot to Lazydog and Christian for their help.

About the _VAR issue: it's with underscore in both Delphi and C++, but the crucial point is that it's wrong to use it for flags! Seems like flags are stored as values of type long and not var... anyway just write p->flags |= VISIBLE and it works.

Quote: yes you can use buttons and sliders in c++ and yes my code works perfectly in delphi.

No problem after converting your code to c++
but have you (tried) used digits ?
Digits just dont show up on the panel, buttons, sliders etc does.
