You can open files from different projects at the same time, but only one project displays in the project pane. To switch between projects, select it from the project toolbar's drop-down list or the Window menu. The name of each file is displayed on its tab at the top of the file in the content pane. When you click on a tab, that file becomes the current file, and its project becomes the active project in the project pane. To customize the content pane tabs, select Tools|IDE Options and change the settings on the Browser page.
The content pane also lets you split the source view of a file into two or more vertical or horizontal panes. This setting applies to an individual file, not to all the opened files in the content pane. You can have a different configuration for every opened file.
To split the view into panes, right-click in the content pane when the Source tab is selected and choose either Split Vertically or Split Horizontally. To return a split view to one pane, right-click in each source pane and choose Close View.
The content pane gives you access to various file views and operations by way of the file view tabs shown at the bottom of each file window. The tabbed pages that are available in the content pane depend on what kind of file you have selected in the project pane. Only tabs appropriate to the opened file will appear below its window in the content pane.
Source | The Source tab displays the Java or HTML source code in the editor for the opened file. |
Design | The Design tab displays the UI designer for the opened file. In the UI designer you can see how the code displays in the user interface, manipulate layouts, create components, use Two-Way Tools, and modify layout properties. |
Bean | The Bean tab exposes the BeansExpress Property, Event, BeanInfo, and Property Editor designers. Use them to add properties and events to your bean, choose what properties are exposed, and create custom property editors. |
Doc | The Doc tab shows the API reference documentation (if available) for the class that is opened in the content pane. |
History | The History tab displays information that helps you manage revisions of files. It displays the source code of the active file and a revision list of previous versions of the file. The features of the history pane vary by JBuilder edition. |
View | The View tab displays the opened HTML file or image file in a browser or image viewer in the content pane. |
Web View | The Web View tab displays the output from your running web file, such as JSPs, servlets, SHTML, and HTML. For JSPs, the Web View tab displays the output from your running JSP. For servlets, this tab displays the output from the running servlet in parsed HTML. |
Web View Source | The Web View Source tab displays raw HTML in the content pane. |
