各位前輩好,

最近測試2017時,發現按ctrl來複製物件

在拖拉的動作上,畫面會頓頓的,不知道這個來源是什麼呢?

我使用的系統是win10,i5,20G記憶體,SSD硬碟,也有顯卡

謝謝

原因是LabVIEW 2016後的 New Feature "LiveDrag",佔去太多顯示效能。

 

[連結2] 長期解法 LiveDrag = False

在C:\Program Files\National Instruments\LabVIEW 2017\LabVIEW.ini

最後增加一行LiveDrag = False並儲存,不太需要在意這行後面你要留著幾行空行。重新開啟LabVEW 2016/2017即可生效。

 

64-bit Windows + 32-bit LabVIEW,請改

C:\Program Files (x86)\National Instruments\LabVIEW 2017\LabVIEW.ini

 

[連結3] 短期解法或上述做法無效時

請暫時性測試在複製拖拉的過程中,按下鍵盤上的'x',進行功能切換。先前在2016上稍做測試是有效的,可以親自試試長期解法下,短期解法切換時,Move與Copy一個While Loop的行為反應。

LabVIEW 2016 Features and Changes

Improvements to Selecting, Moving, and Resizing Objects

LabVIEW 2016 includes usability improvements to selecting objects, moving objects, and resizing structures on the front panel or block diagram.

 

  • Moving Objects—When you move selected objects, the entire selection moves in real time. Certain objects, such as structures, rearrange or resize to accommodate the movement of the selected objects.

Solution
 
A feature was added in LabVIEW 2016 to improve the usability of moving objects on the front panel and block diagram. Users will now see the selection they are dragging update its position in real time. However, this feature can also have a negative impact on editor performance for certain operations, particularly in large VIs. 
 
Additionally, with this feature enabled in LabVIEW 2016 the Navigation Window will only update when a drag operation has completed. This behavior is being tracked by CAR 599907. 
 
To temporarily turn the feature off, begin a drag operation and press the x key. To turn the feature off by default, go to the LabVIEW INI file located in C:\Program Files\National Instruments\LabVIEW 2016\ and add the token LiveDrag = False. The feature may then be temporarily toggled back on by pressing the x key during a move operation.

If you find live drag too sluggish, you can temporarily toggle it off by pressing the 'x' key during the drag.

 
It will revert to live drag for the next drag.
 
You can add 'LiveDrag=False' to your LabVIEW.ini file to disable live drag by default.  When live drag is turned off, you can still toggle it back on for a single drag by pressing 'x'.
 
Also, if any single refresh during a drag takes longer than 200 ms, LabVIEW will automatically turn off live update during the drag.  We are aware that for very large panels or diagrams, performance could be an issue, and this was an attempt to automatically mitigate that, but perhaps 200 ms was too conservative.
