Titleless Tool Windows

The simple fact is that I don't like window decorations. MS has sought a look for Windows [as part of their branding] that isn't universally conducive to the effectiveness of the user, imho. Once I'm comfortable with an application I want the decoration to not imped my focus.

This examples is a simple step in that direction by using the tool menu to host icons for window control. The first problem is how to move the tool window. By holding a shift-key the menu can be grabbed to move the window. This is not as much a problem as it might seem - tool windows are put where they need to be and live there.

The icons are built into the system and just need to be added to the menu:

Code:

Main.mII MENUITEMINFO \
        cbSize:         sizeof MENUITEMINFO,\
        fMask:          MIIM_FTYPE or MIIM_BITMAP or MIIM_ID,\
        fType:          0,\
        fState:         MFS_ENABLED,\
        wID:            IDM_SYS_SYSTEM,\
        hbmpItem:       HBMMENU_SYSTEM

LoadMenuIndirectW ADDR .MenuTemplate
mov [g_hMenu], rax
InsertMenuItemW [g_hMenu], 0, TRUE, ADDR .mII
mov [.mII.fType], MFT_RIGHTJUSTIFY
iterate <BITMAP,                COMMAND>,\
        HBMMENU_MBAR_RESTORE,   IDM_SYS_RESTORE,\
        HBMMENU_MBAR_MINIMIZE,  IDM_SYS_MINIMIZE,\
        HBMMENU_MBAR_CLOSE,     IDM_SYS_CLOSE
        mov [.mII.hbmpItem], BITMAP
        mov [.mII.wID], COMMAND
        InsertMenuItemW [g_hMenu], -1, TRUE, ADDR .mII
end iterate


; HBITMAP
HBMMENU_SYSTEM:=1
HBMMENU_MBAR_RESTORE:=2
HBMMENU_MBAR_MINIMIZE:=3
; HBMMENU_MBAR_?:=4
HBMMENU_MBAR_CLOSE:=5
HBMMENU_MBAR_CLOSE_D:=6
HBMMENU_MBAR_MINIMIZE_D:=7
HBMMENU_POPUP_CLOSE:=8
HBMMENU_POPUP_RESTORE:=9
HBMMENU_POPUP_MAXIMIZE:=10
HBMMENU_POPUP_MINIMIZE:=11
HBMMENU_CALLBACK:=-1

By using command ids that match the SYSMENU commands there is almost no code to support the functionality:

Code:

IDM_SYS_SYSTEM          := 0xF090 ; SC_MOUSEMENU | SC_KEYMENU
IDM_SYS_RESTORE         := 0xF120 ; SC_RESTORE
IDM_SYS_MINIMIZE        := 0xF020 ; SC_MINIMIZE
IDM_SYS_CLOSE           := 0xF060 ; SC_CLOSE

.WM_COMMAND:
        cmp r8w, IDM_FILE_QUIT
        jz .WM_DESTROY
        cmp r8w, 0xF000
        jc .default
        SendMessageW rcx, WM_SYSCOMMAND, r8, r9 ; mimic standard WS_SYSMENU use
        jmp .processed

The code is on github.
