New Table Widget

Table Widget at Runtime

Changed:

When the Input process executes, after the Pre-Display event point runs, the Table Widget(s) will be loaded. Each Table Widget will execute the Event Points in the Table Source process as described above. You can prevent a Table Widget from loading by setting --- WIDGET RELOAD DATASOURCE to "N" in the Pre-Display event point. You might want to do this if the PCF for the Table Source contains a large number of records, and you don't want the table loaded until the user has a chance to enter some filter criteria.

When the Input process executes, after the Pre-Display event point runs, the Table Widget(s) will be loaded. Each Table Widget will execute the Event Points in the Table Source process as described above. You can prevent a Table Widget from loading by reading the --- WIDGET record(s), setting --- WIDGET RELOAD DATASOURCE to "N" and rewriting them in the Pre-Display event point. You might want to do this if the PCF for the Table Source contains a large number of records, and you don't want the table loaded until the user has a chance to enter some filter criteria.

If you have specified an Option for either the Single click or Double Click actions, then those Options will fire when the user clicks a row. This is no different than the user clicking a button that fires an Option, so the Option Intercept event point will execute first. If --- OPTION still contains the USER XX value after the Option Intercept event point ends, then Appx will continue it's normal processing, i.e., it will attempt to run the specified Optional Child, then re-execute the normal event points for the image, including Pre-Display. This means your Table Widget will be re-executed as well, and the data reloaded (unless you have turned off the --- WIDGET RELOAD DATASOURCE spec). If you do not want this to happen, you should set --- OPTION to blank in the Option Intercept Event Point. Conversely, if you want the Table Widget to reload, but do not want all the other Event Points in the Input process to fire, you can use the --- .WIDGET RELOAD DATASRC subroutine, then set --- OPTION to blank. Since --- OPTION is blank, no other event points will execute, and since --- WIDGET RELOAD DATASRC was run, the Table Widget will re-execute.
