Custom Gui - How to hide the label?

To be honest, I'm not sure at all. 

This entire CustomGUI/CustomDataType/resource description/dialog description/dynamic description stuff confused and is still confusing me. No promises made, but sometime I will write an article for the SDK docs, to get this sorted.

On the other hand I tried it here in one of my private plugins.
I just double checked (the plugin contains indeed a CustomDataType as well).
Here's my code:

Int32 ColorHarmonyCustomGuiData::GetId() { return CUSTOMGUI_HARMONY; }
  
CDialog* ColorHarmonyCustomGuiData::Alloc(const BaseContainer& settings)
{
  m_pDlg = NewObj(ColorHarmonyCustomGuiWheel, settings, GetPlugin());
  if (!m_pDlg) {
    return nullptr;
  }
  return m_pDlg->Get();
}
  
void ColorHarmonyCustomGuiData::Free(CDialog* dlg, void* ud)
{
  if (dlg) {
    DeleteObj((GeDialog*&)dlg);
  }
}
  
const Char* ColorHarmonyCustomGuiData::GetResourceSym()
{
  return "HARMONY";
}
  
CustomProperty g_cpHarmonyWheelProps[] =
{
  { CUSTOMTYPE_LONG, HARMONY_RGB_FIRST, "NUM_HARMONIES" }, // SDK Support Test
  { CUSTOMTYPE_END, 0, nullptr }
};
  
CustomProperty* ColorHarmonyCustomGuiData::GetProperties()
{
  return g_cpHarmonyWheelProps;
}
  
Int32 ColorHarmonyCustomGuiData::GetResourceDataType(Int32*& table)
{
  static Int32 l_table[] = { DTYPE_COLOR, CUSTOMDATATYPE_GRADIENT, CUSTOMDATATYPE_HARMONY };
  table = l_table;
  return sizeof(l_table);
}

And in a test resource file, I used:

COLOR ID_TESTOBJECT_HARMONY { FIT_H; SCALE_H; ANIM OFF; CUSTOMGUI HARMONY; NUM_HARMONIES 5; }

I'll double check the LONG datatype tomorrow.

Thanks Andreas! Not only to you is it confusing. I don't even want't to tell how much time I had
to invest to get around the CustomGui and CustomDataType stuff. It's poorly documented/explained.

One idea came up while I read your reply: Maybe it doesn't work because the ID of my property
conflicts with an existing ID? BANNERGUI_ICONID for instance has the ID 1000. I'm gonna check
this tomorrow.

That wasn't it. The obvious solution was to make a CustomDataTypeClass plugin that exposes the
same custom properties. The settings will be merged in the same BaseContainer that is passed to the
iCustomGui.

I have only one problem left, unfortunately. I want one of the custom properties to be a String.

static CustomProperty BannerGuiProperties[] = {
  { CUSTOMTYPE_LONG,   BANNERGUI_ICONID,         "ICON_ID" },
  { CUSTOMTYPE_LONG,   BANNERGUI_BGCOLOR_ID,     "BGCOLOR_ID" },
  { CUSTOMTYPE_VECTOR, BANNERGUI_BGCOLOR_VECTOR, "BGCOLOR_VECTOR" },
  { CUSTOMTYPE_FLAG,   BANNERGUI_TRANSPARENT,    "TRANSPARENT" },
  **{ CUSTOMTYPE_STRING, BANNERGUI_HALIGN,         "ALIGN_H" },**
  { CUSTOMTYPE_LONG,   BANNERGUI_WIDTH,          "WIDTH" },
  { CUSTOMTYPE_LONG,   BANNERGUI_HEIGHT,         "HEIGHT" },
  { CUSTOMTYPE_FLAG,   BANNERGUI_LOCKSCALE,      "LOCKSCALE" },
  { CUSTOMTYPE_END, 0, "" },
};

But when the property is specified in the Description resource, the entry in the settings container I
get in the iCustomGui is empty (DA_NIL). If the property is left out, I get the default value that I
initialized in CustomDataTypeClass::GetDefaultProperties() (which is fine).

        GROUP {
            BANNER TEST { ICON_ID 5159; WIDTH 16; ALIGN_H "center"; LOCKSCALE; TRANSPARENT; }
        }

class BannerGuiDataType : public CustomDataTypeClass {

An idea where the problem could be? Thanks!

	//won't read res file!!

Hmm, not sure if that's the problem but get rid of the "":

          
            BANNER TEST { ICON_ID 5159; WIDTH 16; ALIGN_H center; LOCKSCALE; TRANSPARENT; }

Also, you shouldn't require a custom datatype to get the settings. At least it works here with a custom gui finely.

Niklas,
have you been able to get it working?

On 22/05/2015 at 06:00, xxxxxxxx wrote:

No unfortunately not. But I had an idea: Could it be that String  custom property can not be a hardcoded
string inside the description resource, but must instead be a resource symbol that will be loaded from the
stringtable? I'll try it out as soon as I can.

Hmm, I don't think so. The above way does not work for you?
In my custom gui I get the string in the constructor with

m_unit = settings.GetString(MY_UNIT);

and in my description resource it looks like this
REAL ELEMENT_ID { MIN 0; MAX 100; CUSTOMGUI FXUNIT; MY_UNIT SQR_METER; }

then I get a string from the stringtable with

if(m_unit.Compare("SQR_METER")==0)
unit_str = GeLoadString(DPIT_SQR);

works all fine here.

Katachi, that is actually what I meant in my previous post. And right now I see in the SDK, the
documentation of CUSTOMTYPE_STRING says: "String data. (An ID from the string table.)".
So, to use it, it must be set up like this?

mydescription.res

CONTAINER mydescription {
    GROUP {
        BANNER MY_BANNER { TITLE MY_BANNER_TITLE; }
    }
}

mydescription.str

STRINGTABLE mydescription {
    MY_BANNER_TITLE "The string to be passed to the TITLE property here";
}

I thought I could use it to write in-line strings into the description. I wanted to use it to specify the
alignment of the banner image using the words "left", "center" and "right" instead of using integers
like -1, 0 and 1 respectively.

Solved [x]

On 22/05/2015 at 06:38, xxxxxxxx wrote:

yes, exactly like that. Yeah, directly inline won't work but well you can still use LEFT, RIGHT and CENTER instead of MY_BANNER_TITLE right? You would just add each of them to your .str file like:

LEFT "Left";
CENTER "Center";
RIGHT "Right";

But my plugin is a Custom Gui plugin, and the other plugin that makes use of the Custom Gui should
not need to add LEFT CENTER and RIGHT to its Stringtable when it wants to use the Custom Gui.

It doesn't have to. The other plugin can simply use LEFT, RIGHT and CENTER as well (of course the custom gui must be installed). It doesn't have to redefine them in its stringtable. Or what do you mean?

Oh really? In what Stringtable need LEFT,CENTER and RIGHT be defined then?

On 23/05/2015 at 01:05, xxxxxxxx wrote:

They should be defined in the stringtable of the customgui of yours.
Then once that customgui is installed, the description (and its resources) are registered too so any parsing of your customgui by c4d (no matter where in c4d) shall allow to use these flags.

I kind of feel like I don't get it. I don't see a way to register a stringtable or description resource with a
Custom GUI plugin. And I tried adding it to c4d_strings.str and c4d_symbols.h but I get a message when
the description that uses the Custom GUI is loaded "Symbol 'RIGHT' could not be found".

Tried both ways, in the plugin that uses the Custom GUI and in the Custom GUI plugin itself.

#ifndef C4D_SYMBOLS_H__
#define C4D_SYMBOLS_H__
  
enum
{
  LEFT,
  RIGHT,
  CENTER
};
  
#endif // C4D_SYMBOLS_H__

STRINGTABLE
{
  LEFT "left";
  RIGHT "right";
  CENTER "center";
}

You need to use RegisterDescription (I do it in PluginMessage with C4DPL_INIT_SYS) to have it registered along with your customgui. Then it should work.

Thanks Katachi, that makes sense to me.

Edit: Oh well, I fail at doing good test cases.  Actually no, it doesn't really work  with a LONG prop.
It just uses zero as the value when it can't convert the value to a number, and I didn't notice that my
banner image was centered instead of right aligned in my test case (you might ask yourself how you
can not see that immediately..)

Seems like I can't get this to work atm. When I have time next week I'll make a stripped down custom
datatype plugin and test it again. Thanks for your help Katachi!

Unfortunately, it still doesn't work with a CUSTOMTYPE_STRING propety. But it works with a LONG prop!~~
~~
~~
** nrbannergui.h**
~~
~~
~~

#if 0~~
 ~~enum~~
 ~~{~~
 ~~  LEFT = -1,~~
 ~~  RIGHT = 1,~~
 ~~  CENTER = 0,~~
 ~~};~~
 ~~#endif 

~~
~~
~~
The CustomProperty is
~~
~~
~~

 { CUSTOMTYPE_LONG,   BANNERGUI_HALIGN,         "HALIGN" }

~~
~~
~~
And handled in the iCustomGui constructor as
~~
~~
~~

   Int32 align = bc.GetInt32(BANNERGUI_HALIGN);~~
 ~~  if (align  < 0)       this->alignH = BANNERGUI_HALIGN_LEFT;~~
 ~~  else if (align == 0) this- >alignH = BANNERGUI_HALIGN_CENTER;~~
 ~~  else if (align  > 0)  this->alignH = BANNERGUI_HALIGN_RIGHT;

~~
~~
~~
And since I use the custom property on both the custom GUI and custom datatype, I registered the
description for both.
~~
~~
~~

   if (!RegisterDescription(CUSTOMGUI_BANNER, "nrbannergui")) return false;~~
 ~~  if (!RegisterDescription(CUSTOMDATATYPE_BANNER, "nrbannergui")) return false;

~~
~~
~~
Now I can use it in my plugin description as
~~
~~
~~

   GROUP {~~
 ~~    NR_BANNER  MY_BANNER { ICON_ID 1035231; ICON_ID_HOVER 1035232; BUTTON; BGCOLOR_VECTOR 0.157 0.353 0.663; HALIGN RIGHT; }~~
 ~~  }

~~
~~
