Feb 16, · – Code Editorwindow: Besides the text area for editing code, a code editor in NetBeans contains a toolbar at the top and a breadcrumb at the bottom. The toolbar contains buttons that allow you to quickly navigate through the code. NetBeans IDE is a free and open source integrated development environment for application development on Windows, Mac, Linux, and Solaris operating systems. The IDE simplifies the development of web, enterprise, desktop, and mobile applications . The NetBeans IDE with the C/C++ plugin provides advanced editing features for modifying your source code. To explore these features, we’ll use the Quote project. If you have not already created this project, do the following: Choose File > New Project.

How to Use NetBeans IDE from the Basics
Just want to play with some projects? If you have not already created this project, do the following:. For some types of files, you can use the code folding feature to collapse blocks of code so that only the first line of the block appears in the Source Editor.
Click the collapse icon small box with minus sign in the left margin to fold the code of one of the methods. You can set an option so that when you click on a class, function, variable, or macro, all occurrences of that class, function, variable, or macro in the current file are highlighted. In the customer. All of the occurrences of the Customer class in the file are highlighted with a yellow background.
The right margin also shows markings that indicate points where an occurrence is located in the file. The markings let you see how many occurrences there are without scrolling through the file. You can click the markings to jump to the occurrences that they represent. Open the customer. The IDE also dynamically searches for documentation for the classes, functions, methods and so on, and displays the documentation in a popup window.
On the first blank line of the quote. The code completion box displays a short list that includes the Cpu and Customer classes. A documentation window also opens but displays “No documentation found” because the project source does not include documentation for its code. Use your arrow keys or mouse to highlight a standard library function such as calloc from the list, and the documentation window displays the man page for that function if the man page is accessible to the IDE.
Complete the new instance of the Customer class by typing ” andrew; “. On the next line, type the letter a and press Ctrl-Space twice. The code completion box displays a list of choices starting with the letter a , such as method arguments, class fields, and global names, that are accessible from the current context. Double-click the andrew option to accept it and type a period after it.
Press Ctrl-Space and you are provided with a list of the public methods and fields of the Customer class. You can add comments to your code to automatically generate documentation for your functions, classes, and methods. The IDE recognizes comments that use Doxygen syntax and automatically generates documentation. The IDE can also automatically generate a comment block to document the function below the comment.
In the quote. Type a slash and two asterisks and press Enter. The editor inserts a Doxygen-formatted comment for the readNumberOf class.
Click the readNumberOf class to highlight it in yellow, and click one of the occurrences marks on the right to jump to a location where the class is used. Click the readNumberOf class in the line you jumped to, and press Ctrl-Shift-Space to show the documentation that you just added for the parameters.
Click anywhere else in the file to close the documentation window, and click on the readNumberOf class again. You can generate the full code snippet by typing its abbreviation and pressing the Tab key.
For example, in the quote. Type uns followed by a tab and uns expands to unsigned. To see all the available code templates, modify the code templates, create your own code templates, or select a different key to expand the code templates:.
When you type one of these characters, the Source Editor automatically inserts the closing character. The closing curly bracket and semi-colon are added automatically and the cursor is placed on the line between the brackets. The closing bracket is added automatically. You can use the Find In Projects dialog box to search projects for instances of specified text or a regular expression. The Grep tab uses the grep utility, which provides a faster search, especially for remote projects.
In the Grep tab, type the text or regular expression for which you want to search, specify the search scope and file name pattern, and select the check box Open in New Tab so you can save multiple searches in separate tabs.
Click Find. The Search Results tab lists the files in which the text or regular expression is found. Click the other buttons to show the search results as a directory tree or as a list of files. These options are useful when you perform a search across multiple projects. Double-click one of the items in the list and the IDE takes you to the corresponding location in the source editor. The Classes window lets you see all of the classes in your project, and the members and fields for each class.
Click the Classes tab to display the Classes window. All classes in the project are listed. The Navigator window provides a compact view of the file that is currently selected, and simplifies navigation between different parts of the file.
To navigate to an element of the file, double-click the element in the Navigator window and the cursor in the Editor window moves to that element. Right-click in the Navigator to choose a different way to sort the elements, or group the items, or filter them. The Usages window opens and displays all of the usages of the Customer class in the source files of the project.
Click the arrow buttons in the left margin to step through the occurrences and show them in the Editor, or change between logical and physical view. You can also filter the information using a second column of buttons in the left margin.
The Call Graph window displays two views of the calling relationships between functions in the project. A tree view shows the functions called from a selected function, or the functions that call the selected function. A graphical view shows the calling relationships using arrows between the called and calling functions. The Call Graph window opens and displays a tree and graphical view of all functions called from the main function. If you do not see all the functions as shown here, click the third button on the left side of the Call Graph window to show “who is called from this function.
Expand the endl node to display the functions called by that function. Notice the graph is updated to show the functions called by endl as well.
Click the second button, called Bring Into Focus, on the left side of the window to focus on the endl function, then click the fourth button Who Calls this Function to view all the functions that call the endl function. Hyperlink navigation lets you jump from the invocation of a class, method, variable, or constant to its declaration, and from its declaration to its definition.
Hyperlinks also let you jump from a method that is overridden to the method that overrides it, and vice versa. In the cpu. The ComputeSupportMetric function is highlighted and an annotation displays information about the function. Mouse over the definition while pressing Ctrl, and click the hyperlink. The editor jumps to the declaration of the function in the cpu.
Click the left arrow in the editor toolbar second button from the left and the editor jumps back to the definition in cpu. Hover the mouse cursor over the green circle in the left margin and see the annotation that indicates that this method overrides another method. Click the green circle to go to the overridden method and you jump to the module. Click the Cpu::ComputeSupportMetric item and you jump back to the declaration of the method in the cpu. The Includes Hierarchy window lets you inspect all header and source files that are directly or indirectly included in a source file, or all source and header files that directly or indirectly include a header file.
Right-click on the include “module. By default, the Hierarchy window displays a plain list of files that directly include the header file. Click the right-most button at the bottom of the window to change the display to a tree view.
Click the second button from the right to change the display to all files that include or are included. Expand the nodes in the tree view to see all of the source files that include the header file.
