Can you add a color picker component for vision.

Hate to resurrect this, but this is a great idea and would be really helpful.

Use system.gui.chooseColor()

Was not aware of this, thank you!

I prefer system.gui.chooseColor() as recommended in post 3, but while working on a different problem, I developed a way to manipulate the cell renderer of the dropdown and subsequently began exploring alternate uses for the script. Here is an alternative approach that converts a dropdown component to a color picker:

• Replace the dropdown's string datatype Label column with a color datatype label column:

• Then, use the following script on the dropdown's propertyChange event handler:

if event.propertyName == "componentRunning":
	from javax.swing import DefaultListCellRenderer
	from java.awt import Color
	class ColorCellRenderer(DefaultListCellRenderer):
		def getListCellRendererComponent(self, list, value, index, isSelected, cellHasFocus):
			component = DefaultListCellRenderer.getListCellRendererComponent(self, list, value, index, isSelected, cellHasFocus)
			if index != -1:
				color = event.source.data.getValueAt(index, 1)
				component.background = color
				component.foreground = color
			elif event.source.selectedValue is not None:
				selectedValue = event.source.selectedValue
				color = event.source.data.getValueAt(selectedValue, 1)
				component.background = color
				component.foreground = color
			else:
				component.background = event.source.background
				component.foreground = event.source.background
			return component
	renderer = ColorCellRenderer()
	event.source.setRenderer(renderer)

Here is the result:

Note: for this script to run in the designer, preview mode must be on when the window is opened

I imagine that this could be useful if there is a need to limit the color choices
