Question 1

How to data-bind a table in Glimmer DSL for SWT?

Accepted Answer

Use the `items bind(model, :collection)` syntax with column properties, as shown in the Hello Table sample. This automatically syncs table rows with model data and handles edits bidirectionally.

Question 2

Glimmer vs Shoes for Ruby GUI development?

Accepted Answer

Glimmer is more mature and offers multiple backend DSLs with data-binding, while Shoes is simpler but less feature-rich. The README mentions 'If You Liked Shoes, You'll Love Glimmer!' highlighting Glimmer's advanced capabilities.

Question 3

Can I package a Glimmer app as a native executable?

Accepted Answer

Yes, Glimmer DSL for SWT supports native packaging into DMG/PKG/APP on Mac and MSI/EXE on Windows. Other DSLs may have varying packaging support, so check the specific gem documentation.

Question 4

Is Glimmer DSL for LibUI stable for production?

Accepted Answer

No, the README states LibUI is 'an incomplete mid-alpha only,' so it's best for prototyping or simple apps. For production, consider more mature options like SWT or Tk DSLs.

Question 5

How to create custom widgets in Glimmer?

Accepted Answer

Use the custom widget scaffolding support; for example, in SWT DSL, define a class mixing in Glimmer and use DSL syntax. The README highlights scaffolding options for reusable widgets.

Question 6

Glimmer or Tk for simple Ruby desktop apps?

Accepted Answer

Tk DSL offers fast startup and light memory but has non-native widgets on Linux. Glimmer's Tk DSL is good for simple apps, while SWT DSL is better for enterprise features. Choose based on trade-offs in the comparison table.
