Move Up and Down Tree Control Sub-items Programmatically in LabVIEW
July 10th, 2009
In my current project, I’m using a tree control to store the test items and the test operations are taken in sequence following the tree control’s top to down order. To make the test more flexible, the test sequence(here is the tree control’s items order in this program) should be able to modified by the user. The user should be able to move test item up and down in this test sequence tree control.
LabVIEW provides the basic tree item move VIs, but in the actual test project, there is more to be considered and much more work to do. In my project, I use a two level tree to store the test sequence, the top level is the test item’s category and the sub-level is the test items as the following picture.
