Migrating to GUI

Conference - 2002

Migrating to GUI

How do you get there from here?

Migrating to GUI

you must decide if character mode is an ongoing requirement or if it can be abandoned after migrating to GUI.

Before you begin...

Migrating to GUI

• Character mode Auto-GUI

• Single Application - Duplicate Processes

• Dual Applications

• Single Application - Dual mode processes (coming in 4.2)

Four Strategies

Migrating to GUI

• Advantages:– Easiest

• Most applications run “without change”

• Applications can be easily “tweaked” for best possible auto-GUI effect

– Fastest - Up and running immediately

– Looks better than character mode

– Can be starting point for full GUI

• Disadvantages:– GUI is limited to “basic” presentation

Character Mode Auto-GUI

Migrating to GUI

• Buttons on menu and input images

• Title Bar with 3 buttons

• Pull-down menus– System (Direct Process 1)

– Application (Direct Process 2)

– Process (Current Process)

• Check boxes for Logic fields

• Horizontal scrolling within field

• Scrolling text fields

Character Mode Auto-GUI

APPX Release 4.1

• Scan indicators (Binoculars)– PCF scan

– DLU scan

– SCAN statement (ILF)

• List box for token fields

• List box for alpha table fields

• Scrolling screens– Boxes around column headings

– Separator lines between fields and records

– Scroll bar

Character Mode Auto-GUI

• Title Bar

• Buttons

• Process Pull-down

• Column heading boxes & blue text

• Horizontal lines between records

• Vertical lines between fields

• Box around selected record

• Scroll bar

• Scan indicator

• Check box for Logic fields

• Separator under column heading

• List box for Token fields

• SCAN indicators

Migrating to GUI

• No new applications or databases

• Two sets of menus

• Different startup process (menu) depending on user ID or Client type

• Two sets of input processes

• Use design transfer to make a copy of each menu and input process

• GUI-ize one copy of each menu and input process

Single Application - Dual Processes

Migrating to GUI

• Two versions of each application– For example:

• TAR CH (character mode applications)

• TAR GC (GUI mode applications)

• Shared data files– Two databases

– One “uses” the other’s data files

• Different startup database depending on user ID or Client type

Dual Applications - Different Versions

Migrating to GUI

• Create a copy of the applications

• Give them a different version code

• Reengineer each menu process

• Reengineer each input image

• Reports and Inquiries do not require any changes

Design New GUI Applications

Migrating to GUI

• Reengineer each menu process– Image

• Define named resources for wallpaper, logos, icons, etc.

• Replace top row with title bar

• Replace “option” text with buttons

• Add boxes around groups of buttons

• Define tab order for buttons

• Replace “other” text with GUI labels

• Add wallpaper or background color

• Add logo graphic

Design New GUI Applications

Migrating to GUI

• Reengineer each menu process– Navigation aids for each menu item (Optional

child process)• Define named resources for icons

• Add Pull-down menus

• Add Toolbar buttons

• Add Right-click menu items

Design New GUI Applications

Migrating to GUI

• Reengineer each input process– Same as menu processes

– Specify GUI attributes for data fields• Type of control and size

• Text font, style, color, scaling

• Border Style and color

• Other

– Add boxes around groups of fields

– Define tab order for fields
