My learning of Gtk basics on Haskell.

Translating Gtk documentation

https://github.com/haskell-gi/haskell-gi#translating-from-the-c-api-to-the-haskell-gi-generated-api

Example function

GI.Gtk	Gtk
mainQuit	gtk_main_quit

Makes the innermost invocation of the main loop return when it regains control.

mainQuit

https://hackage.haskell.org/package/gi-gtk-3.0.18/docs/GI-Gtk-Functions.html#v:mainQuit

gtk_main_quit

https://developer.gnome.org/gtk3/stable/gtk3-General.html#gtk-main-quit

Example property

GI.Gtk	Gtk
sensitive	GTK_WIDGET_SENSITIVE

sensitive

https://hackage.haskell.org/package/gi-gtk-3.0.18/docs/GI-Gtk-Objects-Widget.html#g:299

GTK_WIDGET_SENSITIVE()

https://developer.gnome.org/gtk2/stable/GtkWidget.html#GTK-WIDGET-SENSITIVE:CAPS

Example signal

GI.Gtk	Gtk
onButtonClicked	“clicked”

onButtonClicked

https://hackage.haskell.org/package/gi-gtk-3.0.18/docs/GI-Gtk-Objects-Button.html#v:onButtonClicked

The “clicked” signal

Gtk documentation

This document is for the GTK+ 3 library, version 3.22.26 https://developer.gnome.org/gtk3/stable/

Lots of reference material. https://developer.gnome.org/references

Working in the REPL

In terminal type stack ghci, it will load ghci REPL in the package context. If you do it in eshell you will get available functions auto-completion.

Typing :browse *Main will give you a list of interesting data that can be searched with Emacs. You can grep though the results by using following example if you are looking for Button related information.

echo ':browse! *Main' | stack ghci | grep Button

Typing Gtk.ma will offer auto-completion for mainquit, pressing Enter will prompt you the correct case.

*Main> Gtk.mainquit

<interactive>:3:1: error:
    Not in scope: ‘Gtk.mainquit’
    Perhaps you meant ‘Gtk.mainQuit’ (imported from GI.Gtk)
    No module named ‘Gtk’ is imported.
*Main>
