    Owner Drawn Menus

    Does anyone know any tutorials on the internet that cover Owner Drawn Controls, specifically Menus? if you are saying to yourself: "Why would anyone want an owner drawn menu?" well, i am trying to achieve the "Office XP Menu Style", i know how to draw the menu in the client window (using PatBlt()) but i cant find out how to draw ON the menu itself.

    Don't know of any tutorials offhand, sorry. The basic idea however is this:

    --Load or create your menu
    --Set up a MENUITEMINFO structure so fMask = MIIM_TYPE, fType = MFT_OWNERDRAW and dwTypeData = whatever you feel like (usually a pointer to an application defined struc)
    --Set the menu item(s) as owner drawn by calling SetMenuItemInfo.
    --In your parent window proc, handle the WM_MEASUREITEM and WM_DRAWITEM messages. MSDN has good documentation on these items.

    That's basically it.

    office XP style? do you think that's how they did those? There is a shadow and such that I'm not sure you could simulate with an ownerdraw. I was assuming that they just made their own control rather than using actual menus. I'm probably wrong about that. I'd be curious to hear how it goes.

    Don't like that solution? Here's another one, although far more involved and invites many bugs.

    --Create 2 custom controls one for the menu bar and one for the popup menus.
    --In each, handle all applicable mouse messages and painting. Make sure to install a timer to handle when your mouse moves in/out of the client area of your custom window otherwise if the mouse moves too fast you'll get items staying high-lighted
    --Don't forget to leave room in the window for extra data -- you're probably gonna need a linked list to store all the menu items, and you'll wanna save the pointer to that list in GWL_USERDATA or similar
    --You'll have to create the menu as a child of your app window. This'll mess up any drawing you were doing in the client area which you can fix either by using creating yet another window or drawing everything about 20 pixels lower.
    Or, you could intercept WM_NCCALCSIZE, reserve yourself some area in the non-client area of the window, create the menu as a child of the desktop and try to coordinate the position and size of the menu bar with the position and size of your parent. Good luck with that one.

    (and I'm pretty sure Office created their own control for this, as you mentioned)

    Have fun

    Here is an example of the menu i want to copy (using the API, instead of MFC):

    i tried to look at MSDN before, but i just dont understand what they are doing, thats why i was looking for a tutorial

    Since your original post was about Owner Drawn Menus, here's some code regarding such to get you going. Sorry if it isn't the cleanest... just started C++ a couple of days ago... built it from DevC++ so there's the comments in there...

    There's a cheap resource file, and a skeleton for the WM_DRAWITEM and WM_MEASUREITEM messages.

    The basic idea is this: get the menu. Set the first item as owner-drawn. Then set it to 400 pixels wide. When DrawItem is called, draw a rectangle (green if selected) and then draw some text over top.

    If you wanna add image lists or whatever later it's easy enough to do.

    Code:
    #include <windows.h>
    
    LRESULT CALLBACK WindowProcedure (HWND, UINT, WPARAM, LPARAM);
    char szClassName[ ] = "WindowsApp";
    char szMenuString[ ] = "Some Text";
