Thus, you would end up using either a conventional [[PUI]] dialog, or create custom widgets from scratch. | Thus, you would end up using either a conventional [[PUI]] dialog, or create custom widgets from scratch. | ||
Alternatively, a good/better workaround may be to use a raster image and register event listeners, to show an embedded canvas with the actual canvas displayed separately - that is an approach that F-JJTH originally came up with. | Alternatively, a good/better workaround may be to use a raster image and register event listeners, to show an embedded canvas with the actual canvas displayed separately - that is an approach that F-JJTH originally came up with.

Basically, you'd have a "shell" with controls (think widgets) and an inner canvas showing the actual graph, which is accomplished using clipping (you can treat another canvas as a raster image and place it in an outer canvas) - for example, the red area is treated as a screen region, where the instrument is displayed, whereas the outer area is just a conventional raster image that responds to "events" to set up the instrument/oscilloscope): | Basically, you'd have a "shell" with controls (think widgets) and an inner canvas showing the actual graph, which is accomplished using clipping (you can treat another canvas as a raster image and place it in an outer canvas) - for example, the red area is treated as a screen region, where the instrument is displayed, whereas the outer area is just a conventional raster image that responds to "events" to set up the instrument/oscilloscope): | ||
