LQ (pronounced "Luke") is a set of LabVIEW bindings for the Qt toolkit. It lets LabVIEW programmers create dynamic, flexible, and powerful GUIs.
LQ is currently focussed on the widget classes, but other major technologies from Qt are planned for inclusion in future releases.
Development Platforms
- LabVIEW 2016 or newer (32-bit and 64-bit)
Deployment Platforms
- Windows (as supported by LabVIEW)
- NI Linux RT 19.0 or newer (x64)
First, add the LQ feed to NI Package Manager (NIPM):
- https://jksh.github.io/LQ-Bindings/feeds/win_x86/ or
- https://jksh.github.io/LQ-Bindings/feeds/win_x64/
Then, install the LQ package:
For step-by-step instructions, read the Windows setup guide.
First, add the LQ feed via NI Measurement & Automation Explorer (NI MAX):
Then, install the LQ package:
For step-by-step instructions, read the NI Linux RT setup guide.
Open LabVIEW, then open the NI Example Finder (Help > Find Examples...) and
search for the keywords "LQ" or "Qt".
Here is a video compilation of some of the examples:
Copy example code into your own block diagram and modify it.
If a class has already been loaded into LabVIEW's memory, it is accessible via the Quick Drop menu. Otherwise, drag it from Windows Explorer onto your block diagram (from vi.lib\addons\LQ\).
NOTE: LabVIEW palette entries are planned for future releases.
This is a pre-alpha release, which means (i) the API will likely change in the near future, (ii) the library is far from feature-complete, (iii) performance is not optimized, and (iv) you might experience crashes. Other issues include:
-
You currently can't disconnect signals, except by calling LQCoreEngine.lvclass:Stop Engine.vi.
-
QWinThumbnailToolButton cannot be applied to non-Qt windows, such as LabVIEW front panels.
