Masters are like Templates *

When you need to create many similar screens, you can create a Master screen and derive other screens from it:

• All derived screens will display widgets from a master.
• Any changes made to a master screen will also be automatically applied to all derived screens.
• Some attributes of master’s widgets (like captions and such) can be altered on derived screens. What can’t be altered are the position and size of the widgets derived from a master.

Example:

• A web heading is usually the same on many screens in a web application; thus it is a good tactics to place heading widgets on a master (as opposed to making separate copies for each screen).

You can manage the masters in Masters panel, below the Screen Tree:

Any changes made on a master will be applied to all derived (child) screens:

• Adding a widget will display that widget on all derived screens.
• Changing a caption on a widget will change it on all derived screens

When changes will not be propagated:

• Change won’t be propagated to any widgets that has been altered; they will retain their own values instead.

Creating and Applying a Master *

Create a new master in one of two ways:

• Copy an existing screen and paste it into Masters panel.
• Create a blank master by “New Master” command above the Masters panel:

Apply a master to a screen:

• Right-click on a screen and choose “Apply Master to Screen” option, then choose one of the existing masters to apply.

To unlink a screen from a master:

1. Right-click on a derived screen and choose “Unlink Screen from Master”.

2. Choose whether to delete derived widgets or to leave them as copies:

Identifying Screens Derived from Masters *

When a screen is derived from a master, you can recognize it by a master indicator icon on a Screen Tree:
