PowerWeb app example - Event Management (Part 4)

#1 Post by SlavkoDam »

Application Event Management.

This is an application for browsing and editing events. It is an Alaska CXP application example which is developed in the PowerWeb way.

Below is the code for creating pages in the application, which are displayed in the following screenshots. You can see in the code that each web UI component is created with a single-function call and its attributes are set in Xbase++ language and style
without HTML/CSS. You can find the complete code in the attachment of the Part 1 post about the new PowerWeb library.

Code: Select all

                {"DTOC(s_date)","Start",,80},;
