Description
A QControl is an object-oriented alternative to using an XControl. Use QControls to receive the benefits of XControls without the headaches.
- Easily allow for UI Logic Code reuse.
- Encapsulate and decouple the UI Logic away from the Business Logic of the main application.
- Allow use of multiple UI Skins while implementing the same UI Logic.
- Abstract away complicated UI Logic from the main application development.
Release Notes
New features and bug fixes:
For MulticolumnListboxSelection:
- Added Get and Set Selection which can be used via Property Node, Selected Items.
- Added Select All.vi and Deselect All.vi methods.
- Added Selection Change user event that fires anytime an item is toggled.
For TreeSelection and MulticolumnListboxSelection:
- Toggle will not happen for disabled items.
For TreeControl:
- Fixed issue where Get Children.vi returned the root rather than empty children array if the item had no children.
For Linux OS:
- An error would occur on install because of actions to integrate into the LabVIEW IDE in Linux paths were different than Windows. Now it should resolve the paths correctly.
