Selecting a Widget Display
Some slot types have multiple widget configurations that can be selected from the Widget Type menu. For example, a String slot can have a number of different widgets, such as a TextFieldWidget, TextAreaWidget, a UniqueStringWidget, or a YellowStickyWidget. By experimenting with these widgets, you can learn how to use them to get the desired display.
You can also remove a widget from the form by hiding it completely.
Using the Selected Widget Type Menu
To select a different display for your widget from one of the available configurations:
Click the widget you wish to edit in the Form Editor. The widget will be outlined.
Click the Selected Widget Type menu. A list of possible widget types will be displayed.
Select the type of widget that you wish to use.
Using the Configure Form Dialog Box
You can also select different widgets, using the Configure Form dialog box.
To change the widget type for the slot:
Double-click on an empty part of the form to display the Form Configuration dialog box.
Click on the widget name in the widget column. A menu will show the list of standard widget types for the slot.
Note: If the menu does not display, click on the down arrow at the right.
Select the widget you want.
