Edit and execute displays

EDIT Mode

In EDIT mode, QtEDM functions as a display editor. You can:

• Create new displays or open existing ADL files
• Add, select, move, resize, and delete widgets
• Edit widget properties through the Resource Palette
• Copy, cut, and paste widgets
• Group widgets into composites
• Save displays to ADL files
• Toggle grid display and snap-to-grid

The Object Palette provides access to all available widget types. Click on a widget type, then click and drag on the display to create a new widget.

EXECUTE Mode

In EXECUTE mode, QtEDM connects to EPICS and displays live process variable data. Widgets become interactive:

• Monitor widgets display current PV values
• Control widgets allow operators to modify PV values
• Dynamic attributes change widget appearance based on PV values
• Related Display buttons open additional screens
• Shell Command buttons execute system commands

When QtEDM starts without -x, use the Edit/Execute selector in the main window to change modes. A command-line EXECUTE launch locks the selector for that process. Ctrl+X remains the standard Cut shortcut in EDIT mode; it is not a mode switch.
