Circular Light Indictor Widget

Hello,

Does PowerShell Studio sport a circular light/LED type On/Off indicator of any type. I'm not finding one in the Toolbox. Maybe there is a way to make a button circular and make that function of a light indicator?

Thanks.

There is no build in or custom control set for this, but you could create your own.

It is possible to override the CheckBox's Paint event and draw an image, but that is a bit advanced. I recommend searching the web for C# examples.

If you were to use a Button with an image, you would have to track the state outside of the control and toggle the image within your script.

I would just use an picture control and paint a circular color in the center. Set the paint color to red or green as needed. It shouldn't take more thanabout 5 lines of code.

You could also just add two images (LED) and set the image as needed.

A third possibility is to use the XAML/WPF custom control to host the WPF LED control.

Here is a quick and dirty example. You can resize the LED without changing the code.

Using images would allow you to use pictures of LEDs or stoplights as an annunciator/indicator.

Same control and code but altered for new look in the designer.

Thanks Mr. V - nice idea.
So to add images we can use open button in PS studio and just add our BMP/JPG.
To add an image programmatically is it:
$checkboxONOFF.image = [System.Drawing.image]::FromFile('c:\redcircle.bmp')?
