Question 1

How to handle mouse clicks in GOCUI?

Accepted Answer

Mouse support is built-in; set up event handlers using SetKeybinding with mouse events like gocui.MouseLeft to capture clicks and movements, as referenced in the features.

Question 2

GOCUI vs tcell for terminal UIs in Go?

Accepted Answer

GOCUI is higher-level with overlapping views and a simpler API for UIs, while tcell is lower-level for raw terminal control with better performance. Choose GOCUI for rapid UI development and tcell for fine-grained control.

Question 3

Can GOCUI applications be resized dynamically?

Accepted Answer

Yes, but it requires manual handling in the layout function to recalculate view coordinates on terminal resize, which can add complexity to the codebase.

Question 4

How to create a custom widget like a button in GOCUI?

Accepted Answer

Build reusable widgets by defining functions that set up views with specific properties and keybindings, leveraging the io.ReadWriter interface for content, as suggested in the features for complex layouts.

Question 5

Does GOCUI support Unicode or special characters?

Accepted Answer

GOCUI relies on the terminal's capabilities, so Unicode support depends on the terminal emulator, but it can handle colored text and basic special characters within Go's string handling.

Question 6

What are the performance implications of using overlapping views?

Accepted Answer

Overlapping views can impact rendering speed in complex layouts, as each view must be drawn separately, but for typical terminal applications, the performance is generally adequate.
