How to update title of plugin

[SinghRajenM]

I am working on a plugin where I need to update the title of the plugin based on the selected document.

How this can be done.

tTbData tbData;

tbData.uMask = DWS_DF_CONT_BOTTOM | DWS_ADDINFO;
tbData.pszName = TEXT("pszName");
tbData.pszAddInfo = TEXT("pszAddInfo");
tbData.dlgID = 0;
tbData.iPrevCont = -1;

SendMessage(_hParent, NPPM_DMMREGASDCKDLG, 0, (LPARAM)&tbData);

A referenced bug: https://github.com/notepad-plus-plus/notepad-plus-plus/issues/2389

I know that NPPM_DMMUPDATEDISPINFO accepts the handle instead of tTbData. Hence, this bug might have been marked invalid.

Is there any way to update the title?

AFAIK NPPM_DMMUPDATEDISPINFO is only for updating the tbData.pszAddInfo field, i.e., the text in the title bar of the dialog, e.g.:

1. before sending NPPM_DMMUPDATEDISPINFO

2. after sending NPPM_DMMUPDATEDISPINFO

That may not be what you want. If you’re talking about the Plugins menu on the main application’s tool bar, try NPPM_GETMENUHANDLE instead: https://npp-user-manual.org/docs/plugin-communication/#2049nppm_getmenuhandle

@rdipardo this is what I wanted. Thanks!

I wanted to change the title of plugin based on the filename.
e.g. Json Viewer Panel - new 1 to Json Viewer Panel - new 2 when user switches from new 1 to new 2

Adding tbData.pszAddInfo works. However, I does not have control over delimiter. E.g. changing - to : or something else. But I am ok with - to as well.

Gotcha. As you said above, the LPARAM must be a handle to the docking dialog. An example involving an instance of StaticDialog shows _hself being passed.

The - separator is indeed fixed. It is only drawn when pszAddInfo is not NULL, but I don’t know of any public method for customizing it.

Yes, it is fixed as we can see it here . Also, it seems we need to ensure tbData.pszAddInfo remains valid. If you want to change anything there, update the text on the original pointer.

I feel, instead passing _hself to LPARAM, it should pass tTbData to NPPM_DMMUPDATEDISPINFO.

Anyway, - is very minor stuff here. I am good with it. Thanks for the help on this.
Cheers!
