Create a GUI with UI Designer

Create a graphical user interface with predefined objects from the UI Designer toolkit.

The UI Designer toolkit provides an easy drag-drop method to create graphical user interface designs without manual coding. The intuitive workflow lets you assemble a GUI design with predefined objects, preview and modify the design, then save the design as an OML code skeleton that you can further develop.
  1. From the ribbon, select Tools > UI Designer.
    The UI Designer opens in a new window.
  2. Drag objects from the Widget box into the Dialog to create your GUI design.
    The following example shows a simple GUI with a list box, slider, radio buttons, push button and labels.
  3. Modify the location, name, and properties of each object as required for your design.
    • To adjust location, select the object and move it with your mouse or arrow keys.
    • To modify properties, select an object, then modify the desired properties in the Property Editor.

      You can also right-click an object and define a number of properties through the context menu.

  4. From the UI Designer ribbon, select the Preview button.
    A preview of your graphical user interface design is displayed. Review your design, then close the Preview window.
  5. Save your design and specify your preferred file format:
    Save As Descrption
    *.ui Saves your design as a UI Designer file. Use this file format when you want to continue working on your design through UI Designer.
    *.oml Use this format to generate a code skeleton.
    Note: Once you save your design as code, you cannot load it back into the UI Designer. If you want to keep a working verision of your design that you can open through the UI Designer, save a version in .ui format before saving as code.
    When the design example from above is saved as an .oml file, the following code is produced:

    function radioButton_2_callback(handle, callstate)
      % Add callback implementation: [radioButton_2]
    end
    
    function pushButton_callback(handle, callstate)
      % Add callback implementation: [pushButton]
    end
    
    function popupMenu_callback(handle, callstate)
      % Add callback implementation: [popupMenu]

  6. Return to the Twin Activate window and load the .oml file with your design.
  7. Run the file.
    The software produces a GUI based on the code file you saved through the UI Designer.
