@ -8,15 +8,13 @@ This repo includes both a cross-platform Go package providing
(simple dialogs that interact graphically with the user),
as well as a *“port”* of the `zenity` command to both Windows and macOS based on that library.
**This is a work in progress.**
Lots of things are missing.
For now, these are the only implemented dialogs:
Implemented dialogs:
* [message](https://github.com/ncruces/zenity/wiki/Message-dialog) (error, info, question, warning)
* [text entry](https://github.com/ncruces/zenity/wiki/Text-Entry-dialog)
* [list](https://github.com/ncruces/zenity/wiki/List-dialog)
* [password](https://github.com/ncruces/zenity/wiki/Password-dialog)
* [file selection](https://github.com/ncruces/zenity/wiki/File-Selection-dialog)
* [color selection](https://github.com/ncruces/zenity/wiki/Color-Selection-dialog)
* [text entry](https://github.com/ncruces/zenity/wiki/Text-Entry-dialog)
* [password](https://github.com/ncruces/zenity/wiki/Password-dialog)
* [notification](https://github.com/ncruces/zenity/wiki/Notification)
Behavior on Windows, macOS and other Unixes might differ slightly.
