The System Tree – PB Docs 125

Using the Workspace tab page

The System Tree has a single tab page that provides a view
of the current workspace. The Workspace tab page displays the current
workspace and all its targets. Most targets display the library
list for the target and all the objects in each PBL. The Workspace tab page in the
System Tree works like a tree view in the Library painter, but you
can keep it open all the time to serve as the control center of
the development environment.

You can set the root of the Workspace page to your computer’s
root directory, the current selection, or any directory or library,
as well as to the current workspace.

Working with targets

To see the pop-up menu that lets you perform operations on
a target such as search, build, and migrate, you must set the root
of the System Tree to the current workspace.

The following illustration shows a workspace with two targets.
The first target, orders, has a second library in its library search
path.

Current target

The orders target is
bold, indicating it is the current target, which means that it is
the default target used in the New dialog box and for Run and Debug.
The current target is set whenever you:

• Invoke
  an action in the System Tree, Library painter, or main menu that affects
  a target or a child of a target, such as Build, Migrate, Run, or Debug.
  Some actions, such as Search and Migrate, display a dialog box.
  If you cancel the action by clicking the Cancel button in the dialog
  box, the current target is not changed.

• Open an object painter.

• Change the active object painter.

If you prefer to set the current target explicitly using the
Set as Current Target pop-up menu item for the target in the System
Tree or the File>Set Current Target menu item, clear the
Automatically Set Current Target check box on the Workspaces tab
page in the System Options dialog box. To open the System Options
dialog box, select Tools>System Options from the main menu.

Actions in the System Tree

You can use the Workspace page as the hub of your PowerBuilder
session. Pop–up menus let you build and deploy targets
and open and edit any object. Double-clicking an event or function
in the System Tree opens its script in the Script view. Events with
scripts have a different icon and are listed before events without
scripts.

Table 1-1 lists
the actions you can take on each item that displays on the Workspace
page. You can also set properties for each item, choose which object
types display in the tree view, change the root of the Workspace
page, and reset the root to the current workspace.
