HowTo set hIconTab for DockingDlgInterface?

[MarioRosi]

Hello,

i create a DockingDlgInterface and show it.
But i will set the tTbData::hIconTab.

The icons is stored in resource file

i hav try :

bool ChangeIDDialog::ShowDLG(bool bShow)
{
  bool mustShow = bShow && !isVisible();
    if (mustShow)
    {
      if (!isCreated())
      {
        tTbData data = { 0 };
        create(&data);
        data.uMask = DWS_DF_CONT_RIGHT;
        data.pszModuleName = getPluginFileName();
        data.pszName = this->titel.c_str();
        // try 1 == NULL
	data.hIconTab = (HICON)::LoadImage(getHinst(), MAKEINTRESOURCE(IDPNG_CHANGE), IMAGE_BITMAP, 16, 16, LR_LOADMAP3DCOLORS | LR_LOADTRANSPARENT);
        // try 2 == NULL
	data.hIconTab = (HICON)::LoadIcon(getHinst(), MAKEINTRESOURCE(IDPNG_CHANGE));
	// the dlgDlg should be the index of funcItem where the current function pointer is
	data.dlgID = static_cast<int>(MyMenuId::Menue_Measure_SetID);
	::SendMessage(_hParent, NPPM_DMMREGASDCKDLG, 0, (LPARAM)&data);				
      }
      DockingDlgInterface::display(bShow);
    }
    return mustShow;
}

the data.hIconTab is allways NULL.

I have also try with bmp instance of png, also NULL.

The resource IDPNG_CHANGE is compiled into dll, see with “Resource Hacker”.

How can i use the recource image for hIconTab?

regards Mario

I think that you cannot convert a png into an icon in this way. If an icon is expected, I believe that’s what you must supply.

Perhaps try this with a *.ico file, just as a test. If that works, then you’ll know you need to convert your png into an ico before adding it to your resources.

@Coises

thanks for the idea.

It is a partial solution. With an icon its create the icon-handle with

...
data.hIconTab = (HICON)::LoadIcon(getHinst(), MAKEINTRESOURCE(IDI_CHANGE));
...

But the DockingDlgInterface don not display the icon…

@MarioRosi Have you set the DWS_ICONTAB bit in data.uMask?

You need to set that for the icon to display.

I think I might publish my highly overengineered replacement for DockingDlgInterace at some point cos the current one takes a lot of experimentation to get right.

Yes, please!

Your mask is not set correctly:

data.uMask = DWS_DF_CONT_RIGHT | DWS_ICONTAB;

Cheers.

@Michael-Vincent

thanks, that it

@Alan-Kilborn Working on it here. I will probably fiddle with the API (and clang settings) and the documentation is definitely still in need of serious work, but it builds and runs

C++17 is required.

Feel free to play with it/raise issues/…

It is now officially on my to-do list. :-)
Thanks for your efforts.

I gave it a quick try (with Vis. Studio 2022 Community Ed.) but was confused by this from the docs:

The layout of this assumes you have created a repositories directory and cloned the notepad++ template repo and this repo into there.

Since there are no releases of this, I simply got a zip of the code and extracted it to a folder. Building the .sln I got not-found errors regarding PluginInterface.h which reminded me that I needed the real “notepad++ template” code, so I went and got that, but I was unsure where to put it in the source tree…

---

Later EDIT:

In Vis. Studio’s “Solution Explorer” for the new template code, I see there’s a Notepad++ Headers folder which references PluginInterface.h. Looking at what path it thinks that is at, I see it is at the same level as the base folder for this new template, thus I think this is what’s needed:

• ...\myfolder\Docking_Dialogue_Interface-master\ <-- new template code
• ...\myfolder\plugintemplate\ <-- official Notepad++ template code

With this, the “not found” problems seem to be cleared up, but I get some different errors from that point onward…

@ThosRTanner , should I open an issue on the site for the project to continue discussing, so as to not annoy uninterested readers here?
