Customizing the Squeak UI
Last updated at 6:26 pm UTC on 24 January 2020
Customizing Squeak's Look & Feel. See also FAQ: Look and Feel.

There are two different UI's available in Squeak,
- Morphic and
- MVC.
MVC (Model-View-Controller) is the original Squeak UI, it looks a bit outdated, and is no longer the default interface which Squeak starts up in.
Morphic is the newer UI (see the link for details). Most of the following customizations apply for Morphic, but some will also work with MVC. To work in the Morphic environment, see Setting up a Morphic project.

Customizing the UI within Squeak

There is a 'Do' menu attached to the Dock and World Menu which can be edited and thus customized.
Customize Squeak by editing the do menu entries

You might want to give the project a name.

The easiest way to customize Squeak's UI is via the main menu (world menu), in MVC or Morphic.

There are several UI appearance changes that can be made from the "appearance..." submenu under the world menu.
These include changing

The other important place to look is in the Tools menu Preferences window in the top menu.
To get to the same window you may also choose the world menu and then 'appearance...' and then 'preferences...'. This applies to versions 2 up to 5.3.

Some key UI preferences include inboardScrollbars (for fixed vs. flop-out scrollbars), scrollBarsOnRight, roundedWindowCorners, and fastDragWindowInMorphic (for dragging a window outline versus a live window). Use the balloon help to learn more about the other preferences.

To set the background to an image, see FAQ: How can I give my Morphic world a wallpaper?. Also, see the Squeak FAQ for other UI tips, including changing fonts.

In Squeak 5.1 UserInterfaceThemes were introduced. To use them choose the menu 'Extras / Themes & Colors'.
