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!
