Best way to add a toolbar to a dockable dialog

dipaolov

For the plugin I’m developing, I would like to add a dockable dialog to the left side of Notepad++, with a toolbar and a treeview. I found the Tree Control to add to the dialog within my resource file, but didn’t find anything like a toolbar.

So my question is, what is the simplest way to add a toolbar to a dockable dialog? Could you suggest me some existing plugin to take as an example?

Thanks,
Vince.

@dipaolov ,

The builtin Function List feature has a toolbar on its dockable window, so maybe its code would help.

The NppFTP plugin has a toolbar on its dockable window, so maybe its code would help.

The Search Engine That Knows All tells me that https://learn.microsoft.com/en-us/windows/win32/controls/create-toolbars might tell you how to create a toolbar for a window.

@PeterJones thanks. That search engine of your seems neat, one of these days I gotta try it out.

Thanks again,
Vince.

Helllo, @dipaolov, @peterjones and All,

Regarding the search engine, I suppose that Peter :

Ask, first, for the google site, if not its default opened site
Put the two words create and toolbar in the Google search box and simply hit the Enter key ;-))

Among all the results, the first one should be the right one !

@guy038 I don’t believe you, it can’t be that easy.

My solution after considering the options available. The approach is the one used by the Notepad++ code for the Function List panel, but slightly different where some data structures are not visible by the plugin code.

First of all, create an empty dialog in the resource file. Then use the following code in the .CPP file:

INT_PTR CALLBACK ProjectDlg::run_dlgProc(UINT message, WPARAM wParam, LPARAM lParam)
{
	switch (message)
	{
		// the dialog is being initialized
		case WM_INITDIALOG:
		{
			// create the toolbar with the specified style
			int style = WS_CHILD | WS_VISIBLE | CCS_ADJUSTABLE | TBSTYLE_AUTOSIZE | TBSTYLE_FLAT | 
				TBSTYLE_LIST | TBSTYLE_TRANSPARENT | BTNS_AUTOSIZE | BTNS_SEP | TBSTYLE_TOOLTIPS;
			_hToolBar = ::CreateWindowEx(0, TOOLBARCLASSNAME, NULL, style,
				0, 0, 0, 0, _hSelf, nullptr, _hInst, NULL);

			// set the bitmap size
			::SendMessage(_hToolBar, TB_SETBITMAPSIZE, 0, MAKELPARAM(24, 24));

			// get the icons from the resources
			TBADDBITMAP addbmp = { 0, 0 };
			const int nbIcons = 8;
			int iconIDs[nbIcons] = { IDB_NEWPRJ, IDB_OPENPRJ, IDB_SAVEPRJ, IDB_ADDLIB,
									IDB_RMVLIB, IDB_ADDFILE, IDB_COMFILE, IDB_COMALL };
			int iconDarkModeIDs[nbIcons] = { IDB_NEWPRJ_DM, IDB_OPENPRJ_DM, IDB_SAVEPRJ_DM, 
												IDB_ADDLIB_DM, IDB_RMVLIB_DM , IDB_ADDFILE_DM,
												IDB_COMFILE_DM , IDB_COMALL_DM };
			for (size_t i = 0; i < nbIcons; ++i)
			{
				int icoID = ::SendMessage(nppData._nppHandle, NPPM_ISDARKMODEENABLED, (WPARAM)0, (LPARAM(0))) ? iconDarkModeIDs[i] : iconIDs[i];
				HBITMAP hBmp = static_cast<HBITMAP>(::LoadImage(_hInst, MAKEINTRESOURCE(icoID), IMAGE_BITMAP, 24, 24, LR_LOADMAP3DCOLORS | LR_LOADTRANSPARENT));
				addbmp.nID = reinterpret_cast<UINT_PTR>(hBmp);
				::SendMessage(_hToolBar, TB_ADDBITMAP, 1, reinterpret_cast<LPARAM>(&addbmp));
			}

			// set up the buttons
			TBBUTTON tbButtons[nbIcons];

			tbButtons[0].idCommand = IDC_NEWPRJ;
			tbButtons[0].iBitmap = 0;
			tbButtons[0].fsState = TBSTATE_ENABLED;
			tbButtons[0].fsStyle = BTNS_BUTTON | BTNS_AUTOSIZE;
			tbButtons[0].iString = reinterpret_cast<intptr_t>(TEXT("New project..."));

			// set up all the other buttons

			// set up the tool bar and show it
			::SendMessage(_hToolBar, TB_SETMAXTEXTROWS, 0, 0);
			::SendMessage(_hToolBar, TB_BUTTONSTRUCTSIZE, sizeof(TBBUTTON), 0);
			::SendMessage(_hToolBar, TB_SETBUTTONSIZE, 0, MAKELONG(24, 24));
			::SendMessage(_hToolBar, TB_ADDBUTTONS, sizeof(tbButtons) / sizeof(TBBUTTON),
				reinterpret_cast<LPARAM>(&tbButtons));
			::SendMessage(_hToolBar, TB_AUTOSIZE, 0, 0);

			::ShowWindow(_hToolBar, SW_SHOW);

			// create the other controls

			
		// the dialog was resized
		case WM_SIZE:
		{
			// get the new width and height of the panel
			int width = LOWORD(lParam);
			int height = HIWORD(lParam);

			// get the size of the toolbar
			RECT toolbarMenuRect;
			::GetClientRect(_hToolBar, &toolbarMenuRect);

			// move the toolbar to the top with a margin
			int margin = 1;
			::MoveWindow(_hToolBar, margin, margin, width, 
				toolbarMenuRect.bottom, TRUE);
			// set the size of all the other controls
		}
		// manage the other messages
		
	}

	return DockingDlgInterface::run_dlgProc(message, wParam, lParam);
}

Hope this will help someone eventually.
