Custom Widgets (meters and compass)

[Dave Hazen]

I am preparing a GUI and am looking for custom/customizable widgets (and don't want to reinvent the wheel). The two applications are for replicating a compass (0-360 degrees, North up) and providing background sectors on a numericmeter to show acceptable/unacceptable ranges of values (ie somehow make red and green zones).
Is there anything out there that I can access - or a recipe for customizing the distributed widgets (numericgauge and numericmeter.

I'm not sure about the specific controls that you want but you can look at how custom controls are made by viewing the source for the custom controls that come with CVI in the cvi\toolslib\custctrl directory. There are also example projects that show how to use these in the cvi\samples\userint\custctrl directory.

I spent a few minutes making a compass rose display the other day, I'll attach it here i anyone wants to use it.

With reference to acceptable / non acceptable ranges, you can try experimenting with color ramp settings that are available for some numeric controls (all but numeric and color numeric), like in the example below:

Hi, I answered in your other thread with a possible solution for a compass. In the future try not to spread the same question over multiple threads to avoid confusion.

The controls used there are standard CVI controls so you can set their values with a simple SetCtrlVal; is there a special reason for using an ActiveX control like the one you showed us?
