<![CDATA[Add new API NPPM_ADDTOOLBARICON_FORDARKMODE for dark mode]]>Usage:
void NPPM_ADDTOOLBARICON_FORDARKMODE(UINT funcItem[X]._cmdID, toolbarIconsWithDarkMode iconHandles)

This new API NPPM_ADDTOOLBARICON_FORDARKMODE is for replacing obsolete NPPM_ADDTOOLBARICON which doesn’t support the dark mode.
2 formats / 3 icons are needed: 1 * BMP + 2 * ICO

All 3 handles below should be set so the icon will be displayed correctly if toolbar icon sets are changed by users, also in dark mode.

	struct toolbarIconsWithDarkMode {
		HBITMAP	hToolbarBmp;
		HICON	hToolbarIcon;
		HICON	hToolbarIconDarkMode;
	};

You can find the demo here:

Was just starting to implement darkmode icons…
What happens with plugins used in older versions of NPP?
I guess I’m not the only one facing this for some time.
I would implement both messages and make the choice by the NPP version:

         if (8 <= HIWORD(execute(nppHandle, NPPM_GETNPPVERSION))) { // version 8 did introduce the dark mode
            g_TBIconsDrk.hToolbarBmp = (HBITMAP)::LoadImage(_findDlg.getHinst(), MAKEINTRESOURCE(IDB_TB_ANALYSE), IMAGE_BITMAP, 0, 0, (LR_DEFAULTSIZE | LR_LOADMAP3DCOLORS));
            g_TBIconsDrk.hToolbarIcon = (HICON)::LoadIcon(_findDlg.getHinst(), MAKEINTRESOURCE(IDI_ANALYSE_NEW));
            g_TBIconsDrk.hToolbarIconDarkMode = (HICON)::LoadIcon(_findDlg.getHinst(), MAKEINTRESOURCE(IDI_ANALYSE_NEW_DRK));
            execute(nppHandle, NPPM_ADDTOOLBARICON_FORDARKMODE, (WPARAM)funcItem[SHOWFINDDLG]._cmdID, (LPARAM)&g_TBIconsDrk);
         }
         else {
            g_TBIconsOld.hToolbarBmp = (HBITMAP)::LoadImage(_findDlg.getHinst(), MAKEINTRESOURCE(IDB_TB_ANALYSE), IMAGE_BITMAP, 0, 0, (LR_DEFAULTSIZE | LR_LOADMAP3DCOLORS));
            g_TBIconsOld.hToolbarIcon = (HICON)::LoadIcon(_findDlg.getHinst(), MAKEINTRESOURCE(IDI_ANALYSE));
            execute(nppHandle, NPPM_ADDTOOLBARICON_DEPRECATED, (WPARAM)funcItem[SHOWFINDDLG]._cmdID, (LPARAM)&g_TBIconsOld);
         }

This works with older versions also.
Comments?

Using Fluent icons in non-dark mode with some non-fluent plugin icons and Customize Toolbar plugin - ALL WORKS!!!

I’m not suggesting modifying the struct, just to use the one icon in the struct in all cases to prevent missing icons.

I will see what I can do about it.

OTOH, there’s no way to extend NPPM_ADDTOOLBARICON since the pointer of icons handles structure is passed as arguments.

Many existing plugins are still using this old message. This causes missing icons on the toolbar for plugins when Notepad++ is configured to use Fluent UI.
I would suggest slightly modifying the behavior of NPPM_ADDTOOLBARICON so that it reuses the hToolbarIcon icon in place of the hToolbarIconDarkMode icon.
This would at least allow a plugin to have ugly icons when using Fluent UI rather than icons that are completely missing.

Message NPPM_ADDTOOLBARICON works as usual in the newest version of Notepad++ for all plugins which use this message. It doesn’t support only dark mode.

The new API NPPM_ADDTOOLBARICON_FORDARKMODE for dark mode is here for substituting NPPM_ADDTOOLBARICON, so the retro-compatibility is remained.

OTOH, there’s no way to extend NPPM_ADDTOOLBARICON since the pointer of icons handles structure is passed as arguments.

Since the NPPM_ADDTOOLBARICON message is being deprecated I do have a suggestion.

Many existing plugins are still using this old message. This causes missing icons on the toolbar for plugins when Notepad++ is configured to use Fluent UI.

I would suggest slightly modifying the behavior of NPPM_ADDTOOLBARICON so that it reuses the hToolbarIcon icon in place of the hToolbarIconDarkMode icon.
