Adding Custom Components and Windows
You can add your own custom windows and components to the layout
(without having to add them to a palette):
- Generic Component. Creates a particular type
of component when you specify a component class in the attribute
editor and set its attributes.
- Generic Window. Creates a top-level
window when you specify a frame or dialog class in the attribute
editor and set its attributes.
To add a custom component
with Generic Component:
- Click on Generic Component in the Additional palette.
- Click in the cell where you want to place the component.
- Open the attribute editor by clicking on its button in the main
toolbar.
- Use the
class attribute to specify your
custom component by its full package and class name. By
default, the class attribute of Generic
Component contains java.awt.Button, the
standard AWT button object.
The component must have a null constructor, and it must be a subclass
of java.awt.Component.
- Enter a unique component ID in the name box.
Using Generic Component does not integrate your component into the GUI
builder component palette.
To add a custom window to
the layout:
- Choose GUI -> Add New Window to open the New Window
dialog box.
- Choose Generic Window from the list.
- Click Create.
- Select Generic Window in the mode list (next
to the component palette) to open the attribute editor.
- Use the
class attribute to specify your
custom window by its full package and class name.
By default, the Generic Window class attribute
contains sunsoft.jws.visual.rt.awt.RootFrame.
Your custom window must be a subclass of
sunsoft.jws.visual.rt.awt.RootFrame or
sunsoft.jws.visual.rt.awt.RootDialog
See Defining Attributes for
information on defining attributes for custom shadows or groups.
