Title bars display basic information about a computer window, including the window’s contents and the name of the application it came from. They often have buttons to minimize, maximize, and close the window. The appearance of a title bar varies depending on the application and desktop environment.
A title bar is the area at the top of a computer window that displays basic information about what is contained in that window. Title bars usually contain a brief description of the window’s contents, as well as the name of the application the window came from. Most windows in a computer’s graphical user interface have a title bar, and it’s not very common to see a blank title bar, as properly descriptive title bars can tell a lot about a window.
Title bars are the small rectangular regions that span the top of a computer window, and their descriptions are usually found on the far left. The descriptions may or may not be next to an icon designated by the program the window came from, but usually there is some kind of icon. Typically, the format of the description on the title bar is first a description of the window’s contents, followed by some sort of separator, and then the program name. The main windows of a computer program are more likely to have detailed title bars, and the small dialog boxes that sometimes appear within a program aren’t always as detailed.
On the right or left side of the bar there are often buttons to minimize, maximize and close the window. Like the titlebar descriptions, these buttons tend to get smaller depending on the type of window or dialog being shown. Main windows almost invariably have all three buttons, and some even have a help button nearby. Important dialogs usually have all three buttons as well, although the scaling buttons may be absent or disabled if scaling is not needed. Small message dialogs can have all three buttons, but often only have a close button, because resizing messages is almost never necessary.
The exact appearance of a title bar varies depending on the application that opened it and the specific look of a particular computer’s desktop environment. While it is possible in programming to code the appearance of a title bar, this is often discouraged due to the possibility of it clashing with a client’s desktop environment. When programming, the size, coloring, and general layout of the bar are usually handled by the operating system, so you almost never need to explicitly code them. As both a user and a developer, paying attention to title bars can be crucial, both for informational and understanding purposes, no matter how it looks.
