CMenu problem

[olekba]

Hi !

I making my class what is derive from CMenu.

All items are add to menu with falg MF_OWNERDRAW.

I see that if with MF_OWNERDRAW is use MF_POPUP MeasureItem is NOT call for this Item. Class use his values. I can draw this item, but not in my size and arrow (for show where will be draw next popup) are draw automaticly too.

How support it ?

Thnx in advance

Try handling ON_WM_MEASUREITEM() in your mainframe class. I've used owner draw menus and that's were I handle it.

Problem is, that for this items (POPUP) OnMeasureItem is NOT call too. This is work like without MF_OWNERDRAW, but this flag is add - I'm sure.

You can receive WM_MEAUREITEM messages for popup menus. When you add/insert the popup menu you specify the MF_OWNDRAWN flag.

If its an existing menu then thou need to get he menu item MF_BYPOSITION hand set the MF_OWNDRAWN flag on the item.

Popup menu arrow: Its not possible to render this yourself. Even in you know an item is a popup, windows automatically draws this arrow for you. The only way around is to cause windows to render to an offscreen bitmap and then overdraw its arrow. Its a right pain and really difficult to do, so I would not worry about it.

Mike Harnad is right ! If I move it to mainframe all work super (hera was another one bug, so my preview post was wrong).

All items (without separator ) have this same width now.

THNX A LOT for all for help
