Dynamic ROI Tool tips
All controls have a Tooltip Text property. The text in this property is displayed when the cursor is held over
the control. Tool tips for Image controls with ROIs can contain special keywords that will be replaced by
information about the ROI.
Each type of Image control uses different keywords. Text may be interspersed with keywords, and more than
one keyword can be used in a tooltip text property.
For example, if the tooltip text for a Rectangle ROI is
Inspection Area %extents%
the tooltip will display the text "Inspection Area," along with the ROI values, like this:
Inspection Area 100, 100, 90, 200, 200
The Blob List and Greyscale Template Model do not have dynamic tooltips. Tooltips in these controls are
displayed for individual elements. For example, a BlobList tooltip is displayed when the cursor is held over
each Blob ROI in the list.
