SAP Screen Personas empowers SAP users and developers to customize SAP GUI screens to improve usability, streamline workflows, and boost productivity. One of the interactive features available in SAP Screen Personas is drag-and-drop functionality. This feature enhances user experience by enabling intuitive repositioning of UI elements directly on the screen, allowing more dynamic and flexible screen layouts.
This article guides you through the basics of configuring drag-and-drop functionality in SAP Screen Personas, covering its setup, use cases, and best practices.
Drag-and-drop refers to the ability to click an on-screen element, drag it to a different location, and drop it there to reorder or reposition it dynamically. In SAP Screen Personas, this capability can be applied to various controls such as list items, tables, or container elements within a flavor.
Using drag-and-drop, end users or designers can:
SAP Screen Personas does not provide a built-in drag-and-drop toggle in the GUI. Instead, drag-and-drop behavior is configured using JavaScript scripting within the flavor.
Example approach:
Here is a simplified example of scripting logic to enable drag-and-drop on table rows:
// Find the table element by its ID
var table = session.findById("wnd[0]/usr/cntlTABLE/shellcont/shell");
// Attach drag start event to rows
table.getRows().forEach(function(row) {
row.setDraggable(true);
row.addEventListener("dragstart", function(event) {
event.dataTransfer.setData("text/plain", row.getIndex());
});
});
// Define drop event on table body
var tableBody = table.getTableBody();
tableBody.addEventListener("drop", function(event) {
event.preventDefault();
var draggedIndex = event.dataTransfer.getData("text");
var targetIndex = ... // Determine drop target index
// Logic to reorder rows in the table based on drag-and-drop
reorderRows(draggedIndex, targetIndex);
});
Configuring drag-and-drop functionality in SAP Screen Personas adds a modern, interactive dimension to classic SAP GUI screens. While it requires some scripting effort, this feature can significantly enhance user engagement and customization capabilities. By leveraging JavaScript event handlers within flavors, you can implement flexible drag-and-drop interactions that make your SAP applications more intuitive and productive.
