In this final chapter of part 2 of the book, we round out our discussion of basic Windows Forms programming with the ToolBar and ToolTip classes. You may wonder why these concepts were not presented earlier in our discussion, and they certainly could have been. The reason is either poor planning or clever organization you decide which. These two concepts are not necessarily related, but they do make for a catchy chapter title. Toolbars in Windows Forms applications are created using the ToolBar and ToolBarButton classes. We will look at these classes along with the ImageList class in the first three sections of the chapter. Image lists are used by toolbars and other controls to hold a set of images available for display within the control. The final section in the chapter will examine tool tips and the ToolTip class. Specific topics we will look at in this chapter include: Adding a toolbar to a window. Creating toolbar buttons: push buttons, separators, dropdown menus, and toggle buttons. Associating menu commands with a toolbar button. 410

Here at last is the source of the river: the place where the games come from Development companies exist to do one thing: design and build video games In the early days of the personal computer game business, the developer was usually just one person, a programmer, who did all the art and music (what there was of it) himself Nowadays, most first-class games require teams of 10 to 50 people, and a development company is a full-scale business with administrators and a personnel department If a developer is big enough, it may have several projects going on at once, possibly for several different publishers Publishers tend to be a bit leery of developers who work with more than one publisher at once, since they re afraid that the program code they re paying for may find its way into another publisher s products However, if the developer is good enough, the publisher will either overlook this, or try to give the developer so much work that they don t have time to work for anyone else Development companies tend to be small, rarely more than 200 people, all of them usually highly dedicated to making great games, and most of them more interested in the fun aspects of the game industry rather than in the business and moneymaking aspects These tend to be more relaxed and less corporate places to work, with

Interacting with toolbar buttons. Creating and managing image lists. Providing tool tips for controls in a form. We begin our discussion with toolbars.

Toolbars were added to windowing environments as an alternate shortcut method for common tasks, especially menu bar items. While keyboard shortcuts are fine for more experienced users, they do not have a graphical presence in the window. Toolbars provide a graphic for each shortcut button, so users should be able to quickly perform common tasks without the need to hunt through the menus or documentation all the time. At least that was the theory. Personally, I prefer keyboard shortcuts, and find the plethora of toolbars a distraction in many interfaces. While common tasks such as opening and closing a file or selection of a bold or italic font style have developed somewhat standard graphical buttons, I have trouble deciphering many of the tiny graphics shown on many toolbars and prefer to search for keyboard shortcuts instead. When creating toolbars in your programs, make sure their meaning is clear, and do not use a toolbar as an excuse to avoid keyboard shortcuts and access keys. Some users prefer the keyboard over the mouse, so it is a good idea to provide keyboard as well as mouse access to program functions. But I digress. Let s get back to toolbars in .NET. Whether you employ them yourself or not, your users will likely expect them. In this section we will look at the ToolBar class in detail, create a blank Figure 13.1 Our toolbar will use a raisedtoolbar in our MyPhotos project, and also button appearance for displaying its butintroduce the ToolBarButton class. tons. A flat appearance is also possible. Later sections will look at image lists and the creation of the various kinds of toolbar buttons. By the end of section 13.3, our efforts will produce the interface shown in figure 13.1.
