[Q] OwnerDraw Menu - Large Font - MainMenuBar thickness

S

Stuart Norris

Dear Group,

I am new to c# and windows form designer - coming from a Motif
background.

I am attempting to develop an application for a touch screen and I
need to have a menu system with a larger font to allow ease of
selection.

I have used OwnerDraw menus implementing the DrawItemEventHandler and
MeasureItemEventHandler event handlers.

My attached sample works for the menus, however the MainMenubar
thickness is still the default thickness.

How do I change the Main menu bar thickness? So I can use larger
fonts for my application.

Thanks

Stuart

If you add your menu inside a ReBar control (like menus in internet explorer
or developer studio), then you can set the height of rebar control to
watever you want.

Hi All,

Just a quick followup on this.

Is the only way to change the height of the main menubar using a third
party package.

How do they do it? Do they draw the menus completely differently.

Thanks

Stuie
