Data

If you create a tool group in your MVApp, make sure to connect your tool parameters and results in the Frontend Designer before grouping. For more information, see Connecting to Tools in a Group in Adjusting Your Widgets.

Connected Tool:

Connect to a tool from your MERLIC Vision App by selecting the desired tool from the drop-down menu. You can only select tools that are used in your MERLIC Vision App. At the property Connected Parameter you may then select the parameter whose value you want to adjust with the slider.

Connected Parameter:

Select the parameter of the connected tool whose value you want to adjust from the drop-down menu. The list shows only the parameters of the tool that is selected in the property "Connected Tool". Therefore, you have to make sure that the widget is connected to a tool before selecting a parameter.
