Windows Forms Menu (XNA Style)

 
0
 

XNA Game Studio is not required to use this functionality. This example is very basic, and I typed it up because I was bored. It does not contain functionality for navigation through the menu, but it will display the menu as it should at the specified location. Please enjoy it, and I will revise it later tonight when I'm not busy and update this post with a version that supports navigation. Until then, enjoy. :)

I will add a ton more of functionality to this; things like color, fonts, and other miscelaneous items of normal menus.

***UPDATE***

// v1.2
// I've added colors and fonts to the menu items, as well as set a default value.
// There is only one bug with the update at this time;
// I've set it up so that the font size can be changed,
// But at runtime it's not correctly placing the menu entries;
// I will work on it and get the functionality up to speed.
// Anyways, here is the updated source.
// I've included the empty class template for the event args that will handle the navigation of the menu.
// I'm going to go eat and then get back to work. I haven't eaten anything in about 3 days.
// Loss of appitite.

UPDATE: Fixed all problems but one. The application is updating too fast because I'm using a timer so before the class has a chance to fix it's index value (to prevent it from going out of range) it updates and throws the exception. Other than that it works fine. I've now included navigation functionality.
