A widget is a control in a graphical user interface (e.g. a button or slider). Module behaviour is controlled by parameters which either arrive via the module input port, are controlled by a widget on the Diminutif or maximised control panel, or both.
The following widget types are available for an IRIS Explorer control panel:
- Slider (horizontal or vertical)
- Text box
- Scrolled list
- Drawing area
- Radio button
- Option menu
- File browser
- Check box
- Multi-line text box
Interaction with these widgets is achieved using the left-hand mouse button, and (where appropriate) type-in of text. Users are also able to edit numerical values on dials and sliders (including the maximum and minimum values) by selecting with the left-hand mouse button, typing a new value and pressing <Enter>.
Examples of IRIS Explorer control panel widgets are shown in the figures below.
