what do you mean by dialogue box and its various components?
Answers
dialog boxes enable you to provide input for various functions. The type of dialog box provided depends on the type of input required. Your input might require any of the following: text entry box, check button, radio button, option button, single-selection list, multiple-selection list, two-column selection list, a tabbed box, or a tree structure.
In a text entry box, you can enter numbers or a character string (such as a parameter name)
various components
A tabbed dialog box presents groups of related commands in one location. You select an individual tab by clicking on it, or by using Ctrl+Tab to move between the tabs. Some tabbed dialog boxes require that you navigate through each tab sequentially, with later tabs “grayed out” until you complete required tasks in an earlier tab.
A tree structure presents a hierarchical flow of logical choices from major categories to specific subcategories. Select a major category by clicking on the category. Subcategories appear listed vertically and indented beneath that major category. If you select a subcategory in the same way, further subcategories are listed, and become more specific. Continually selecting subcategories yields the final item in the “branch” of the tree. At this point, instead of a categorical choice, you enter or edit data to provide specific input .
